Presented server AMD Epyc (Naples)
Today, among other things, were presented and server processors AMD Epyc, which we know under the code name of Naples.
Unfortunately, as in the case of Threadripper desktop CPU, AMD solutions Epyc details about the characteristics, range and pricing was not revealed.
AMD boasted that in comparison with direct competitors (which, not specified) new server processors the company will offer 45% more of the engines 122% more memory bandwidth and 60% more throughput interfaces I / o.
In the maximum configuration CPU Epyc will get 32 cores. Thanks to the support of SMT processors can handle up to 64 data streams. You can also select eight-channel memory controller and the presence of 128 PCIe. Here we would point out that data on the number of PCIe lanes is in the official press release, however, on some slides you can see that the 128 lines are for dual-processor systems, so this question remains open.
Due to the huge number of cores, AMD set the system with one CPU Epyc dual processor system Intel. And below you can see the results of the specific comparison with CPU Intel Xeon E5-2699A v4. More precisely, it compares a dual-processor system based on older CPU Epyc and above Intel processors.
You can also see and compare uniprocessor systems, where the enemy flagship AMD supports Intel Xeon E5-2650 v4.
An important aspect is that the CPU Epyc, in fact, represent a single-chip systems, as they contain the required set of interfaces I / o that eliminates the need of using a separate chipset.
Separately, AMD showed a roadmap specific to server-side solutions. As can be seen, followed by CPU, followed by the CPUs with code names like Rome and Milan. The first will use the core Zen 2, and the second will have Zen 3. Both generations will be using seminomatous process.
