Intel Xeon Platinum 8351N vs AMD EPYC 9655

In this CPU comparison, we compare the Intel Xeon Platinum 8351N and the AMD EPYC 9655 and use benchmarks to check which processor is faster.

We compare the Intel Xeon Platinum 8351N 36 core processor released in Q2/2021 with the AMD EPYC 9655 which has 96 CPU cores and was introduced in Q4/2024.

The Intel Xeon Platinum 8351N is a 36 core processor with a clock frequency of 2.40 GHz (3.50 GHz). The processor can compute 72 threads at the same time. The AMD EPYC 9655 clocks with 2.70 GHz, has 96 CPU cores and can calculate 192 threads in parallel.

The performance values of the processor's AI unit. The isolated NPU performance is specified here, the total AI performance (NPU+CPU+iGPU) can be higher. Processors with support for artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors.

Graphics (iGPU) integrated into the processor not only enable image output without having to rely on a dedicated graphics solution, but can also efficiently accelerate video playback.

A photo or video codec that is accelerated in hardware can greatly accelerate the working speed of a processor and extend the battery life of notebooks or smartphones when playing videos.

Up to 6144 GB of memory in a maximum of 8 memory channels is supported by the Intel Xeon Platinum 8351N, while the AMD EPYC 9655 supports a maximum of 6144 GB of memory with a maximum memory bandwidth of 480.0 GB/s enabled.

The Intel Xeon Platinum 8351N has a TDP of 225 W. The TDP of the AMD EPYC 9655 is 400 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The Intel Xeon Platinum 8351N has 54.00 MB cache and is manufactured in 10 nm. The cache of AMD EPYC 9655 is at 384.00 MB. The processor is manufactured in 4 nm.
