AMD has just posted their “Core is Back” teaser over at their Facebook page which hints at an imminent CPU announcement. Now this may sound crazy but this actually coming from AMD’s official Facebook and Youtube pages makes this so much more interesting that we couldn’t wait to find out what this announcement is about actually.AMD Core is Back

AMD CORE IS BACK Teaser Video

AMD Teases “Core Is Back” Teaser and Core Evolution Video

AMD is teasing their upcoming CPU announcement with a picture on their Facebook page and a CGI Video on their YouTube channel. The Facebook page and Youtube Video lists down the following statements:

The war continues to rage and battles may be lost but heroes will evolve.#AMDEvolved via AMD Facebook

“In your PC, applications battle for resources. While powerful CORE hardware fights to maintain the balance. But the war never ends. And the applications only get stronger. Battles may be lost. But heroes will EVOLVE. CORE IS BACK!” via AMD YouTube

When I first saw this picture, I thought it was some fan prompting AMD to release a new CPU but after looking at the teaser video, I become quite excited myself. As you can note, the “Core is Back” title is a conformation that a new CPU announcement is coming and some might even say that core can also be used for GPU but if you take a look at the video, you will notice that applications and CPU have a mutual relationship and makes it the only device to do such a teaser announcement for. The video itself is called “Core Evolution” which hints that the new core technology is an evolution of an existing architecture. So this could be a new FX launch, an updated Kaveri APU or a FX APU based on Steamroller architecture with the iGPU disabled for faster core clock speeds.

Evidence regarding stacked DRAM on next generation AMD APUs has surfaced once again which gives hints that the upcoming Carrizo APU or its successor will be the first APUs to enable high-bandwidth stacked DRAM design on-chip.AMD APUs Carrizo APU Stacked Memory

Evidence Regarding AMD APUs Featuring High-Bandwidth Stacked Memory Surfaces

It has been known for a while that AMD is sampling their first generation HBM (High Bandwidth Memory) and we can find official specifications in slides dating back to December 2013. While there was no mention of what product or application may make use of HBM back then, the latest slides from AMD’s official Fast Forward presentation talks regarding stacked DRAM specifically on APUs. The Fast Forward project’s objectives are to enhance the high volume APU architecture and investigate in next generation processor and memory tech for exascale and consume scale systems.

Within the presentation, you can find several references of stacked memory and new APU technologies such as HSA+, PIM (Processing In Memory) and Two Level memory. Some of these are already part of the current AMD APU family such as Kaveri which introduced several new features such as HSA on software and steamroller, gcn or hardware side.

During the Q2 financial conference call, AMD’s SVP and COO, Lisa Su, assured that their company will out 20nm products next year followed by 16nm FinFET later on. While there have been rumors that AMD might introduce 20nm products in late 2014, I believe that this statement is an end to all those reports since AMD’s entire lineup is to stick with the current 28nm process node this year.AMD 20nm

AMD Assures 20nm Products in 2015 – 16nm FinFET Later On

In Q1 2014, AMD forwarded the same statement that their graphics and semi-custom business products will both stick with 28nm. We have seen several 28nm products across AMD graphics and processors designs which include the Radeon R9 and Radeon R7 series for graphics while Steamroller, Jaguar powering AMD’s processors and accelerated processing units were also based on 28nm.

“We (AMD) will be shipping products in 20 nanometre next year and as we move forward obviously a FinFET is also important,” Lisa Su (Senior Vice President and Chief Operating Officer at AMD) via Fudzilla

This news is interesting for the moment since AMD is on the verge to introduce new graphics processing units for the consumer industry. These include the Tonga, Iceland and Maui which are reportedly launching in Q3 and Q4 2014. So we can more or less confirm that all three of these chips will feature the existing 28nm process design while their replacements which are now believed to arrive 2015 will be based on 20nm. The same goes for AMD’s upcoming semi-custom APUs which are part of AMD’s Skybridge initiative which allows pin-to-pin compatibility for x86 and ARM based processors. The Cambridge APU will feature this technology leveraging the efficiency while the K12 ARM core which is a 64-bit ARM custom designed core will use 16nm FinFET technology. It should be noted that AMD also has a true x86 architecture in development to feed high-performance needs which should not be expected prior to 2016-2017 so we may see it based on a smaller node.

AMD’s Carrizo APU “Mobile” platform specifications and details have been unveiled in a slide posted by VR-Zone. The slide confirms pretty much everything we have known about Carrizo and will end much of the confusion that has been build around the information regarding AMD’s 5th generation of accelerated processing units for their mobile platforms.AMD Carrizo APU Platform Details

AMD Carrizo APU “Mobile” Platform Details Unveiled

The platform details regarding AMD Carrizo APU have been unveiled for the Mobile platform rather the desktop platform but we will believe that the desktop platform will be similar in terms of architecture and design as was with Kaveri generation of processors, earlier this year. If you look at the picture of the slide posted by VR-Zone, you will note that it is very similar to the SteamrollerB powered Kaveri 2.0 platform slide which was leaked almost 8 months ago and turned out to be true at the time of Kaveri’s launch since most of the details reported were accurate.

AMD’s Carrizo APU would become the fifth installment in the Accelerated Processing Units family which will feature the latest Excavator core architecture. From previous leaks, we have come to know that Excavator is based on a 28nm process probably based on GlobalFoundaries since AMD chose it the node for Kaveri too. Powering the CPU side, these new x86 Excavator modular cores will leverage the IPC for greater performance compared to Steamroller. The mobile platform will feature both Quad Core and Dual Core variants but right now, we are looking at a glimpse of the top-end variant which shares 2 MB L2 cache.

Videocardz.com has just released some new information about AMD GPUs. The GPUs in question are ofcourse Tonga, Iceland and Hawaii. As for the Maxwell Mobility news, we have already covered the 870MX a while back. Now we had already told you that the speculated Hawaii XTX with 3072 SP doesn’t exist and now it seems that VC is stating the same, citing a Hawaii core with higher clocks. AMD Tonga GPU

AMD Iceland, Tonga and Hawaii Revision Detailed – R9 390X Allegedly Leaked

Now before we begin, the leak from our source also mentions the fabled R9 390X citing some specs. However the leak of the R9 390X is slightly shady. Here are the reasons why:

[RUMOR] Notice the shiny tag at the start. Continue. We have received some information regarding AMD’s upcoming APU Carrizo, this information is unverified so I will be treating it as a rumor. The report comes from the Italian site bitsandchips.it and states that AMD’s upcoming flagship APUs will have Stacked DRAM while maintaining the 28nm Node.

Carrizo APU RoadmapThe Quite Old ‘Leaked’ Roadmap

Carrizo APU will be based on the 28nm Node and have HBM (High Bandwidth Memory)

Now it goes without saying, that you need to keep that pinch of salt handy throughout this post. However this news, if true, is very interesting. We know for a fact that APUS benefit a lot from good memory and if these APUs will truly support HBM then we can expect to see some very substantial performance per clock gains while jumping from Kaveri to Carrizo even while staying on the same node. Another important point to note is that with the Carrizo APU the implementation of HSA will be perfected resulting in probably significant in compute as well as gaming.

Now we already know that AMD is working with Hynix to create Stacked DRAM.  We also know that this memory will come in two types, namely 3DS and HBM (Don’t be fooled by the lack of 3D in this name, both are stacked). The memory that is in question here is the HBM variant type which will feature the highest bandwidth and I know for a fact that there are two types already in production. Namely the 2-Hi and 4-Hi variants. You can find the detailed analysis of the same in my Pascal Architecture Analysis. Now the max bandwidth of a single HBM is 128-256 GBps (compare this to the 28GBps of GDDR5), so we are looking at an insane growth in bandwidth, albeit at reduced clocks (most probably around 1000Mhz).

‘GTA V PC’ had been the pinnacle of PC release controversy this past year (before Watch Dogs that is) and we are still waiting to see how the game looks after the application of Photoreal mods. Thankfully the game along with other titles could be getting Mantle API support, which needless to put, would be a literal game changer. The info was given to us by our sister site Videocardz.com

GTA V PC

‘GTA V PC’ And Other Titles Could be Getting ‘Mantle API’ Support

“GTA V PC” was the the World’s Most Expensive Video Game ever made (and could still be considering Destiny’s budget is now in question) and if it gets Mantle Support, it would be a massive win for AMD. There are other games that are “Mantle Support Pending” and contain some notable titles such as Call of Duty: Advanced Warfare, but no title will make as big an impact as “GTA V PC”. Now before we go any further lets take a look at the unreleased games that are queued for Mantle Support:

  • Homefront: The Revolution
  • Call of Duty: Advanced Warfare
  • Alien: Isolation
  • Elite: Dangerous
  • Grand Theft Auto V
  • Lara Croft and the Temple of Osiris
  • Kingdom Come: Deliverance
  • Lichdom: Battlemage

A few days ago, we reported that AMD might slash prices off of their Radeon R9 280X and Radeon R9 280 series graphics cards and from the looks of it, the first round of price cuts have already hit the market. While their have been a few pricing adjustments from manufacturer’s, AMD is now sending out the word to slash prices from the Radeon R9 and Radeon R7 series graphics cards.AMD Radeon R9 280 and R7 265

First Round of Price Cuts Hit The AMD Radeon R9 and Radeon R7 GPUs

Computerbase managed to find out that HIS, one of AMD’s biggest AIC partners have started offering price cuts on their cards by as much as $10-$30. The new price cuts aren’t just limited to the Radeon R9 280X and Radeon R9 280 graphics cards but the Radeon R9 270X and Radeon R7 260X are also receiving price reductions which can be seen through several retailers. Judging from the new prices, the HIS Radeon R7 260X is retailing at 99.90 Euro, HIS Radeon R7 265 for 119.90 Euros, HIS Radeon R9 260X for 149.90 Euros and the Radeon R9 280X for 219.90 Euros. Currently, HIS is the only manufacturer who have started offering price cuts on their graphics cards how-ever, other manufacturers will soon follow.

Taking a look over at Newegg, I spotted some really interesting listing under the HIS GPU section. I recently published a review of the HIS Radeon R9 280 IceQ X2 graphics card last week and at that point of time, the card was retailing at $279.99 US over at Newegg. Now its down to $259.99 US and the cheapest variant which comes with the IceQ cooler can be bought for $219.99 US. The official cost of the Radeon R9 280 at launch was $279.99 US and it did receive a price cut to $249.99 US so we are looking at a $30 reduction in its average price. Similarly, the flagship Radeon R9 280X non-reference IceQ x2 variants can now be purchased at the reference MSRP of $299.99 US and we are expecting at least $279.99 US for the reference variants.

AMD has just recently launched the A10-7800 APU of the Kaveri family. The APU is the locked sibling of the Kaveri A10-7850K and features a massive reduction in TDP (30W) taking it down from the 7850K’s 95W to a much more reasonable 65W. The only downside being that the multiplier is locked, though you can still mess with the BCLK. The A10-7800 should be priced around the $145 price point.

AMD Mobility Kaveri APU Features

Kaveri A10-7800 APU Launches – Locked Multiplier, 512 GCN Cores and 65W TDP

Now the APU is based on the Kaveri architecture and actually features the full shader count of the flagship. On the CPU side the APU features steam roller cores that are divided into two blocks. It features the Radeon R7 series graphics with the full 512 GCN 2.0 core count. It supports Mantle API and Direct X 11.2. Basically, more or less the specs are identical like support for DDR3-1866Mhz memory.  The APU is clocked at 3.5Ghz with a Turbo frequency of 3.9 Ghz while the GPU side is clocked at 720Mhz.

The only other differences between the A10-7800 and A10-7850K are  that the flagship is clocked 200 Mhz higher on the base clock and 100Mhz higher turbo clock. Apart from that, the 7800 is the splitting image of the Kaveri flagship with the added bonus of having a much lower TDP rating. Needless to say that for HTPC builds and very casual gaming rigs, this is a god sent chip. The pricing as I already mentioned will be somewhere between 140 and 150 US dollars.

AMD might possibly be preparing to offer another round of price-cuts on their Radeon R9 280X and Radeon R9 280 series graphics card in preparation of the upcoming Tonga GPU. According to Sweclockers, AMD’s is planning to slash prices on the two Radeon R9 280 series graphics cards which feature the Tahiti graphics processing unit which has spanned two and a half years in the graphics industry making it one of the most longest running desktop graphics card entry in the company’s history.r9 280x reference

AMD Radeon R9 280X and Radeon R9 280 To Recieve Price-Cuts – Preparation of the Tonga Chip’s Arrival

The AMD Radeon R9 280X and Radeon R9 280 are based off the Tahiti XT and Tahiti Pro dies respectively. The Radeon R9 280X comes with 2048 Stream processors, 3 GB of GDDR5 memory and a 1000 MHz clock speed at pricing of $299.99 US. The second chip in the line which is featured on the Radeon R9 280 is a cut down Tahiti silicon with 1792 Stream processors and 3 GB GDDR5 memory running across a 384-bit memory interface and priced at $249.99 US. The Radeon R9 280 was initially launched at $279.99 US but AMD quickly responded with price cuts due to the GeForce GTX 760 being quite successful at NVIDIA’s front (and it still holds a successful position in the mid-range market).

The AMD Radeon R9 280X and Radeon R9 280 are essentially the same old Radeon HD 7970 and Radeon HD 7950 we have known since the launch of the Radeon HD 7000 series back in December 2011. Its time for AMD to move ahead and offer something new in the form of the upcoming Tonga GPU. As for the price cuts, it can be predicted that the Radeon R9 280X will cost $279.99 – $249.99 US and the Radeon R9 280 will cost $229.99 US after the price cuts. This puts them in a more competitive position against their GeForce rivals which include the GeForce GTX 760 and GeForce GTX 770. AMD also offers $150 US of value as a part of their Never Settle Bundle promotion which may entice users to join the red team but NVIDIA has their own AAA gaming bundle on their cards too so it all comes down to user preference.

Chinese VR Zone (Via Videocardz) has revealed more details on AMD’s upcoming Tonga GPU. They state that the said GPU will be arriving sometime in August and is all set to replace the Tathiti PRO core and therefore the R9 280 GPU for the mid-end spectrum. Its performance is supposed to be somewhere in between Tahiti PRO and Tahiti XT.

AMD’s Tonga GPU will Replace Tahiti PRO and Radeon R9 280 Sometime in August

The exact nomenclature of the GPU is not known but a common dubbing is the Radeon R9 285, which being nothing more than a speculation, can be easily wrong. The card is rumored to have a 256bit interface with 32 CUs and consequently 2048 SPs. The card is supposedly very power efficient and could even get a 7Ghz memory clock. The fab for the Tonga GPU is said to be Global Foundries, but there are rumors circulating that put it back to TSMC’s 28nm node. Now we had previously heard that the GPU would be landing near Autumn and VR Zone seems to have given a more accurate time frame for the same.

The Tonga GPU is aimed at the completely mid-end spectrum and equal-to-or-less-than $200 price point if it is going to be replacing the R9 280. It is also speculated to be be based on GCN 2.0 as opposed to GCN 1.1 which Hawaii and Bonaire were based on. AS we draw closer to the launch more information about the GPU will inevitably leak out, and from the looks of it, Tonga is shaping up to be a very interesting GPU.  The design scheme introduces latest architectural improvements such as new ACE (Asynchronous Compute Engine) Units and an increased focus towards compute shaders. Leaving aside the choke full of speculation in this article, the only thing that is 100% confirmed at this point is that the GPU is landing in August and will replace the Tahiti Pro.

Update: The ending has been elaborated further.

[Editorial] Wow, these GPU leaks feel like one big roller coaster ride don’t they? just me? Ok. So I just received some pretty startling information from our friend Robbie Pyckhout who runs an emerging site BlackHoleTec. Robbie talked to me extensively via email and provided a wealth of evidence that the Hawaii XTX core, actually doesn’t exist. He has published an article on the same also which can be found on BlackHoleTec.  Now about Hawaii XTX; well I guess I better start from the beginning.

The Hawaii XTX 48CU Core Doesn’t Exist – Does that mean no R9 295XT/XTX ?

Sadly, I cannot reveal much of the evidence he showed me, but rest assured, it was water tight. So heres the thing, one of the major sources of the rumor mill was 8Pack’s revelation, which I quote, stated, “290X is not full fat…… NDA stops me from saying much”. Seems to more or less prove that the core exists right? Well, try looking at the thread now. The comments now reads “Removed”. So either 8Pack is in trouble or there is no such thing as a Hawaii XTX Core and he corrected the mistake. Think that this one tilts both ways? I agree.

Robbie said that anyone can simply X-Ray the Hawaii XT core and notice that there aren’t anymore CUs present there apart from the original 44. You might find an odd number of CUs associated with Yield but thats about it. None of the 48 CUs of the promised Hawaii XTX core will be present. Secondly, you may have noticed that AMD has been suspiciously quiet about all this, why haven’t they denied the existence of the core outright? Well I think I know a very very plausible reason for that. See, AMD is currently in its quiet period. Which means that a publicly listed company (AMD:NYSE in this case) cannot make any announcements about anything that could cause a normal investor to change their position on the company’s stock. This is mandated by the US Securities and Exchange Commission and denial or discussion of the Hawaii XTX Core/GPU most definitely falls into this one. So even if AMD wanted too, they could not squish the rumor right now. Infact, if you were to contact any PR member about this core, they just wouldn’t reply. Which could be erroneously taken as proof after the fact.

Rooting for your favorite graphic card giant is a primary part of any PC Enthusiast, but while it is almost customary for a tech enthusiast to do so, it is less becoming for the giants themselves to engage in low blows and PR Battles. The recent tit-for-tat PR Battle being fought between AMD and Nvidia is about Mantle Titles and the Game Works Library. Both Red and Green are trying their level best to gain the upper hand in being seen as the champion of PC Gaming, but they only thing they are currently achieving is making the trolls reach for popcorn.

NVIDIA GameWorks

Nvidia and AMD’s PR Team Exchanges Low Blows to be seen as the Champion of the PC Gaming World

Although it would seem unintuitive, I guess basic information about the spat is in order. Sometime ago AMD accused Nvidia of using the Game Works library in a negative way. Basically they said that Nvidia was making Game Works completely optimized to run on Nvidia Geforce cards while doing absolutely nothing about Radeon cards. The result is obviously that Game Works titles will perform superiorly on Geforce cards. Nvidia denies this accusation but fairly speaking there is no way to verify Nvidia’s claims because Game Works is a proprietary library and its code is not available to the public. Therefore any optimization has to be done by Team Green themselves. An admittedly tricky situation with no actual way to verify anything, apart from Game Works becoming open, which isn’t happening. However when AMD’s Robert Hallock accused Nvidia of optimizing Watch Dogs primarily for Geforce cards, Nvidia revealed a counter statement which said that the source code in question wasn’t actually necessary for driver optimization and AMD’s accusation s were just PR attacks. Here is the detailed response taken from Forbes.com:

The internet has been abuzz with a lot of news lately. Google’s I/O conference has given us a lot to report and post about. However, no matter what happens, the overclocker community always is hard at work, doing what they do best. Recently we informed you about Intel’s Devil Canyon flagship Core i7-4790K being massively overclocked to 7003.38 MHz. This time, the 8 GHz barrier has been broken, and not once, but twice. The processors are AMD’s FX-8320 and FX-8350 and the enthusiasts are Russians slamms and Atheros.

Russian Enthusiast Slamms Overclocks AMD’s FX-8320 To 8171.53 MHz Using Liquid Nitrogen. The FX-8350 Also Overclocked To 8157 MHz.

chtcbuRussian enthusiast Slamms has set a new record in overclocking AMD’s eight core FX-8320. The enthusiast has managed to overclock the processor to a staggering 8171.53 MHz. This has been done while running the processor in single core mode. The base frequency of the processor is 3500 MHz. The cooling employed by slamms was liquid nitrogen, as is expected in these cases. Core voltage for the processor was 2.16 Volts with maximum TDP being 125 Watts for the processor. The motherboard employed by the enthusiast was Asus CROSSHAIR V FORMULA-Z with 990FX Chipset Power consumption for the run was 1,300 Watt. The memory employed by Slamms was one module of Corsair 4096 MB of single channel DDR3SDRAM. Frequency of the RAM was 702.9 MHz. This run earned Slamms first ranking out of 61 entries for the FX-8320.

Now that Intel’s Haswell Refresh and Devils Canyon are out its time once again for another iteration of an all out round between Intel and AMD processors in terms of Gaming Performance. Basically these aggregated benchmarks are all about which CPU is the best for gaming. The benchmarks were provided to us by udteam.tistory.
