AMD EPYC 'Rome': Zen 2 on 7nm, 64C/128T of CPU power

Crystals for them manufactured by TSMC at the 7-nanometer process technology, the process of the first generation, and GlobalFoundries, a manufacturer of 14-nanometer "system controller".

Rome is set to have 64 Zen 2 cores and increased instructions per cycle, doubling the compute performance per socket. Now pushing up to 64 cores/128 threads, up from the 32 cores/64 threads of the previous gen "Naples" EPYC CPUs.

AMD has already said it's committed to AM4 for its next-generation CPUs, so it's likely Zen 2 won't change that. Earlier this year, the half-generational refresh dubbed Zen+ debuted, complete with its 12nm process found in the second-gen Threadripper CPUs unveiled in August. When matched against a dual-socket Xeon Platinum 8180M server, the AMD box ran the benchmark to completion first. Performance gains in terms of instructions per clock will be improved as well. So the company has been stuck adding ++++ optimizations to their 14nm line which has remained relatively the same for a while now.

Safety is also an inescapable issue for AMD.

Revealing the new chip tech at an AMD press and analyst event in San Francisco on Tuesday, the company said that Zen 2 represents the second and perhaps the most significant step in the architecture's timeline. Especially with regard to Intel's problems with Spectre and Meltdown. Many expect fireworks, which the company seems to have laid out already in Rome. Furthermore, AMD has increased the number of encryption keys for virtualizations for increased virtual machine support. The chips will be manufactured by TSMC on its leading 7nm node, which the company says will give it a significant advantage over Intel, which is now struggling with its own 10nm process. For instance, they can double chip density by two while halving the power consumption. Considering what AMD is now claiming, Rome should be able to match or exceed Intel's highest performing offering in 2019.

AMD will be using a new design approach for the EPYC "Rome" CPU. Furthermore, ROME processors have double floating point width to 256-bit, and has double load store bandwidth with increased dispatch and retire bandwidth.

Intel's long-delayed 10nm manufacturing process still has no specific launch date, with the company still using a 14nm process that's been refined numerous times, stretching all the way back to its "Broadwell" CPUs launched in 2014.
