Intel Xeon Silver 4214Y vs AMD EPYC 7643

Intel Xeon Silver 4214Y or AMD EPYC 7643 - which processor is faster? In this comparison we look at the differences and analyze which of these two CPUs is better. We compare the technical data and benchmark results.

The Intel Xeon Silver 4214Y has 12 cores with 24 threads and clocks with a maximum frequency of 3.20 GHz. Up to 1024 GB of memory is supported in 6 memory channels. The Intel Xeon Silver 4214Y was released in Q2/2019.

The AMD EPYC 7643 has 48 cores with 96 threads and clocks with a maximum frequency of 3.60 GHz. The CPU supports up to 4096 GB of memory in 8 memory channels. The AMD EPYC 7643 was released in Q1/2021.

The Intel Xeon Silver 4214Y has 12 CPU cores and can calculate 24 threads in parallel. The clock frequency of the Intel Xeon Silver 4214Y is 2.20 GHz (3.20 GHz) while the AMD EPYC 7643 has 48 CPU cores and 96 threads can calculate simultaneously. The clock frequency of the AMD EPYC 7643 is at 2.30 GHz (3.60 GHz).

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.

The Intel Xeon Silver 4214Y or AMD EPYC 7643 has integrated graphics, called iGPU for short. The iGPU uses the system's main memory as graphics memory and sits on the processor's die.

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.

The Intel Xeon Silver 4214Y can use up to 1024 GB of memory in 6 memory channels. The maximum memory bandwidth is 115.2 GB/s. The AMD EPYC 7643 supports up to 4096 GB of memory in 8 memory channels and achieves a memory bandwidth of up to 204.8 GB/s.

The thermal design power (TDP for short) of the Intel Xeon Silver 4214Y is 85 W, while the AMD EPYC 7643 has a TDP of 240 W. The TDP specifies the necessary cooling solution that is required to cool the processor sufficiently.

The Intel Xeon Silver 4214Y is manufactured in 14 nm and has 16.50 MB cache. The AMD EPYC 7643 is manufactured in 7 nm and has a 256.00 MB cache.
