Intel's 8th Generation Coffee Lake CPU Family - The First Mainstream Chips From Intel With 6 Cores, 12 Threads

First of all, what is Coffee Lake? In simple terms, Coffee Lake is an improved Kaby Lake that has been made possible with the latest 14nm++ process node. Intel briefed in their webinar that Coffee Lake is on the same architectural level as Kaby Lake with no changes at all. Aside from that, the new 14nm process allows for improved power efficiency and higher clock speeds. There’s a reason that Intel is bumping up the core count across their entire range of processors. The Intel Core i7 and Core i5 lineup gets 6 cores (HT/Non-HT) while the Core i3 lineup gets 4 cores.

The Intel Core i7 and Core i5 processors with 6 cores feature the same TDPs as their predecessors so bumping up the core count hasn’t changed the TDP numbers. Actual power consumption may vary during testing real world applications but for that, you’d have to wait for our review in the coming weeks. You will also note that Intel has given a fairly good bump to both CPU and integrated GPU clock speeds which is only possible with the new and improved 14nm++ process.

Intel Coffee Lake CPUs Have 16 PCIe 3.0 Lanes, PCH Supports 24 PCIe 3.0 Lanes – These Make Up The 40 PCIe Platform Lanes

Now one thing you might have noticed in other articles is that they state the Intel Coffee Lake platform will feature 40 PCIe Lanes. That’s true but not entirely an accurate representation. As you see, Intel does has 40 PCIe 3.0 lanes on their upcoming family but those are a combination of CPU and PCH lanes. All Coffee Lake CPUs feature 16 PCIe Gen 3.0 lanes while the 300 series PCH offers up to 24 PCIe 3.0 lanes. These make up the 40 PCIe 3.0 lanes that Intel claims of.

This means that people can add in two GPUs for SLI or mGPU support which will be given to the CPU while PCH can allow for additional devices such as PCIe / M.2 storage or Intel Optane support.

The Intel 8th Gen, Core Desktop Family Full Specifications and Prices

At launch, Intel will introduce 6 new Coffee Lake CPUs to consumers. These include the flagship Core i7-8700K, Core i7-8700, Core i5-8600K, Core i5-8400, Core i3-8350K and Core i3-8100. Intel includes three “K” unlocked CPUs in the lineup while the rest are locked CPUs that don’t feature overclocking but great for budget users in their own place.

Following are the detailed specs for these CPUs:

Intel Core i7-8700K – The Coffee Lake Flagship With 6 Cores and 4.3 GHz Boost Across All Cores

The Intel Core i7-8700K will be the flagship processor of the lineup. It will feature 6 cores and 12 threads. The chip will be compatible with the LGA 1151 socket on the Z370 chipset only. The chip will be Intel’s first hexa core product and will be based on the 14nm process node.

In terms of clock speeds, we are looking at a 3.7 GHz base frequency which boosts up to 4.3 GHz (6 core) and 4.7 GHz (1 core). These clocks are really impressive so we can expect much faster gaming performance on Coffee Lake parts than the current generation of CPUs. The chip is fully unlocked allowing for overclocking and comes with a TDP of 95W. There’s 12 MB of L3 cache on board along with a GT2 tier iGPU. The chip supports DDR4-2666 MHz memory (native) and up to 4400 MHz+ (OC). The Intel Core i7-8700K will cost $359 US at launch.

Intel Core i5-8600K – The Gamer Aimed Hexa Core With Overclocking Capability and 4.3 GHz Boost

The Intel Core i5-8600K is the second unlocked chip in the lineup and features a hexa core design. We have learned that the Intel Core i5 series will stick with 6 cores but they will not feature a multi-threaded design. The chip probably features 9 MB of L3 cache while being supported on the LGA 1151 socket.

In terms of clock speeds, we are looking at 3.5 GHz base, 4.2 GHz (6 core), 4.3 GHz (1 core) boost clocks. The chip will feature a TDP of 95W and the pricing will be set at $257 US which is just a few bucks over $242 US Price of the Core i5-7600K making it a great option for gamers who want some extra cores inside their rigs.

Intel Core i3-8350K – A Quad Core i3 Processor With 4 GHz Clock Speed

The Intel Core i3-8350K might be the only Core i3 chip in the 8th Gen family that enables overclocking support. Intel’s 8th Gen Core i3 family is also the first to feature 4 cores which will be a great deal for budget builders. The Intel Core i3-8350K comes with 4 cores and 4 threads that are clocked at 4.0 GHz. The chip features 6 MB of cache and will feature a TDP of 91W.

The Intel Core i3 chips will not feature boost clocks but they will have a more stable base clock speed and pricing is set at $168 US for the unlocked model.

Intel Core i5-8400 – A 6 Core Chip Under $200 US, Is This The Dream Gaming Chip?

The one other chip that is worth mentioning is the Intel Core i5-8400. This is a 6 core processor with no hyper threading and no overclocking enabled so what makes it so special? The pricing. The Intel Core i5-8400 has been priced at a remarkable $182 US range which is under the $200 US pricing range. This makes it a very competitive chip for the gaming desktop market as you can have a modern 6 core gaming processor for a fantastic price. We are very interested to test the chip out ourselves.
