AMD EPYC 7663 vs Intel Xeon Platinum 9221

In this CPU comparison, we compare the AMD EPYC 7663 and the Intel Xeon Platinum 9221 and use benchmarks to check which processor is faster.

We compare the AMD EPYC 7663 56 core processor released in Q1/2021 with the Intel Xeon Platinum 9221 which has 32 CPU cores and was introduced in Q3/2019.

The AMD EPYC 7663 is a 56 core processor with a clock frequency of 2.00 GHz (3.50 GHz). The processor can compute 112 threads at the same time. The Intel Xeon Platinum 9221 clocks with 2.30 GHz (3.70 GHz), has 32 CPU cores and can calculate 64 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 4096 GB of memory in a maximum of 8 memory channels is supported by the AMD EPYC 7663, while the Intel Xeon Platinum 9221 supports a maximum of GB of memory with a maximum memory bandwidth of 281.4 GB/s enabled.

The AMD EPYC 7663 has a TDP of 240 W. The TDP of the Intel Xeon Platinum 9221 is 250 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The AMD EPYC 7663 has 256.00 MB cache and is manufactured in 7 nm. The cache of Intel Xeon Platinum 9221 is at 71.50 MB. The processor is manufactured in 14 nm.
