Intel Xeon Platinum 8276 vs AMD EPYC 9684X

In this CPU comparison, we compare the Intel Xeon Platinum 8276 and the AMD EPYC 9684X and use benchmarks to check which processor is faster.

We compare the Intel Xeon Platinum 8276 28 core processor released in Q2/2019 with the AMD EPYC 9684X which has 96 CPU cores and was introduced in Q2/2023.

The Intel Xeon Platinum 8276 is a 28 core processor with a clock frequency of 2.20 GHz (4.00 GHz). The processor can compute 56 threads at the same time. The AMD EPYC 9684X clocks with 2.55 GHz (3.70 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 1024 GB of memory in a maximum of 6 memory channels is supported by the Intel Xeon Platinum 8276, while the AMD EPYC 9684X supports a maximum of 6144 GB of memory with a maximum memory bandwidth of 460.8 GB/s enabled.

The Intel Xeon Platinum 8276 has a TDP of 165 W. The TDP of the AMD EPYC 9684X is 400 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The Intel Xeon Platinum 8276 has 38.50 MB cache and is manufactured in 14 nm. The cache of AMD EPYC 9684X is at 1,152.00 MB. The processor is manufactured in 5 nm.
