AMD Ryzen 3000 CPUs Allegedly Feature 15% Better IPC, Up To 4.5 GHz – X570 Rumored To Have 40 PCIe Lanes, No 3rd Gen Ryzen Support on A320 Boards
It looks like new reports are coming in regarding AMD's next-generation Ryzen 3000 processors which rock the brand new 7nm Zen 2 core architecture. The latest details come from a popular Chinese tech portal who got their information from various motherboard manufacturers who've already received Ryzen 3000 CPU samples.
AMD Ryzen 3000 Processor Samples Clock Up To 4.5 GHz, Feature 15% Better IPC
According to the source, motherboard manufacturers have already been playing around with the AMD Ryzen 3000 CPU samples which they received earlier in Q1 2019. In our previous report, we also confirmed from our own sources that motherboard makers have been supplied quad-core Zen 2 CPU samples to test them with their upcoming products. These CPUs were early samples which were only supplied for internal testing and not necessarily indicate final retail performance or clock speeds.
The report states that the samples allegedly feature a 15% boost in terms of IPC which would be a good increase over existing Zen+ based parts that already lifted the IPC by 3% over Ryzen 1st Gen CPUs. It is also reported that the boost frequency for these samples is reported at up to 4.5 GHz which should scale better with higher core and higher TDP parts. It looks like AMD would make a serious focus on the efficiency of their 7nm processors while delivering a good boost in processor performance over the last generation parts.
It is also reported that the memory controller has got an upgrade but it isn't as significant as we had expected. Still, it would be nice to see Ryzen 3000 series running along well with the higher clocked DDR4 DIMM kits (4000 MHz+). The report also goes in line with the IPC improvements we had expected for the Ryzen 3000 series processors, coming in the 10-15% range.
Here's What To Expect From The AMD Ryzen 3000 Series Processors
The AMD Ryzen 3000 lineup is based on the new Zen 2 core architecture which is made possible with TSMC’s bleeding edge 7nm process node. AMD has reaffirmed that their Zen 2 based Ryzen 3000 series processors for the AM4 desktop platform will be available in mid of 2019. We are now hearing multiple reports of a possible launch in early July and that might be it as far as the launch day is concerned for the new desktop processors.
AMD has made significant changes to their CPU architecture which help deliver twice the throughput of their first generation Zen architecture. The major points include an entirely redesigned execution pipeline, major floating point advances which doubled the floating point registers to 256-bit and double bandwidth for load/store units. One of the key upgrades for Zen 2 is the doubling of the core density which means we are now looking at 2x the core count for each core complex (CCX).
- Improved Execution Pipeline
- Doubled Floating Point (256-bit) and Load/Store (Doubled Bandwidth)
- Doubled Core Density
- Half the Energy Per Operation
- Improved Branch Prediction
- Better Instruction Pre-Fetching
- Re-Optimized Instruction Cache
- Larger Op Cache
- Increased Dispatch / Retire Bandwidth
- Maintaining High Throughput for All Modes
Zen 2 also includes stronger hardware level enhancements when it comes to security. This further solidifies AMD CPUs against enhanced Spectre variants and these mitigations will be adopted fully be Zen 2. When it comes to Zen, AMD already had strong software level support when it came to security and they have further enhanced it through low-level software mitigations.

AMD X570 Chipset – A New House For AMD’s Next-Gen Ryzen 3000 Series CPUs
As we saw with X470, there were a few features for the Ryzen 2000 series processors which were only supported by new motherboards such as Precision Boost Overdrive and XFR 2.0. There’s no doubt that AMD’s Zen 2 based Ryzen mainstream processor family would come with new features but the main highlight would be support for PCIe Gen4. The X570 platform would be all PCIe Gen4 solution which means this would most probably be the first consumer platform to feature support for the new PCIe standard.
That, however, doesn’t mean that AMD Ryzen 3000 series would only be compatible on X570 boards since just like last time, the new CPUs will be backward compatible with X470 & X370 boards too. They certainly won’t display the same feature set that will be available on the newly launched X570 lineup but will feature fully stable functionality for users who just want to drop in a new CPU and continue using their PCs without the hassle of upgrading the motherboard and everything from scratch.
We have also seen the first few teasers from ASRock, Gigabyte and Biostar about their upcoming X570 chipset based motherboards which would be launching at Computex 2019, you can see the teasers here.
AMD X570 Reportedly Offers 40 PCIe Gen 4 Lanes, No Ryzen 3000 Support on A320 Chipset
The same report also states that the X570 platform offers 40 PCIe Gen 4 lanes which would be available from the CPU and PCH. This means that the Ryzen CPUs and X570 PCH will split the Gen4.0 lanes over tons of I/O. A leaked data sheet shows that the X570 PCH is classified in the Enthusiast segment with 16 lanes dedicated to PCIe Gen 4 expansion slots (8+4+4), 8 USB 3.1 Gen 2, 4 USB 2.0, 3 SATA ports (4+4+4_ and an x4 Gen 4 PCIe Uplink port. The rest of the PCIe Gen 4 expansion would run over the CPU lanes.
It is also said that X570 motherboards have encountered a problem with the PCIe 4.0 speeds and a new version of the motherboards are being tested right now which should be ready for launch in a couple of months when Ryzen 3000 series officially hits the market. While X570 is the enthusiast tier PCH, there would also be B550 casual audiences but would lack PCIe Gen 4.0 support.
The X570 launch is scheduled for July along with the 3rd Gen Ryzen processors while the B550 chipset based motherboards would hit shelves at least two months after the launch in late Q3 2019. Also, the A320 chipset would not support Ryzen 3000 series processors which means users running the entry-level boards would have to upgrade in order to run the new CPUs. Various board makers have also supplied BIOS for their current-gen motherboards to support the upcoming CPU lineup.
Motherboard manufacturers are said to be expecting 12 and 16 core parts and would design their upcoming motherboards around this information. So we can see better power delivery and more stable operation for higher core count chips. It only proves that AMD is in a much ready state with Ryzen 3000 series processors and we can't wait to hear more details from the red team on their new mainstream and high-end desktop parts soon at Computex 2019.
