• The AMD Zen 4 Epyc processor could be an epic monster with 128 cores and 256 threads

Next-generation AMD Zen 4 Epyc processors could have up to 128 cores and 256 threads in a single CPU socket, which is double what existing Zen 3 Epyc processors currently have. AMD Zen 4 is the next major architecture revision from the company, codenamed Genoa, and is expected to be a big step up from the existing Zen 3 architecture. While the Zen 4 Epyc processors were known to have more cores than the existing Zen 3 processors, rumors that they would in fact double the number of cores compared to the previous generation are a big deal, assuming the rumors are true.

Wow, ZEN4 has more than 96 cores. I was skeptical when I first saw this news on Chiphell. Now I can also confirm that ZEN4 has up to 128 cores Jun 14, 2021 See More The new Zen 4 processors will also include a higher number of instruction sets, according to Neowin. This expansion would include AVX-512, BFloat16, and others that are critical for high-performance computing workloads as well as server operations, something Intel Xeon used but lacked in AMD Epyc chips.

Doubling cores with extended instruction sets could mean huge performance gains

While instruction sets don't look appealing at all, they can make a big difference in performance. Since a CPU instruction is executed in every CPU cycle, the more complex operations you can perform in a single clock cycle, the better. Otherwise, you will have to prepare for this operation with simpler instructions that require more CPU cycles. This is the difference in performance between direct multiplication of two numbers using a table and additive multiplication with a loop where each addition operation requires a full loop to perform. The power of these extended instruction sets can be seen in this benchmark, pinpointed by Ian Cutress between an octa-core Rocket Lake-S processor and a 2-core Zen 64 processor. < p lang="en" dir="ltr">Test AVX 3DPM Cutting Edge 8 Cores RKL 4,6 GHz AVX512290 W8 32845 pts 64 Cores Zen 23,0 GHz AVX2280 W7 28761 pts Mar 6, 2021 See more With these new extended instruction sets and a doubling of CPU cores and threads compared to Zen 3, the new Zen 4 Epyc processors should be absolute beasts.
