Intel Xeon W-3225 vs AMD EPYC 7642

Intel Xeon W-3225 or AMD EPYC 7642 - 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 W-3225 has 8 cores with 16 threads and clocks with a maximum frequency of 4.40 GHz. Up to 1024 GB of memory is supported in 6 memory channels. The Intel Xeon W-3225 was released in Q2/2019.

The AMD EPYC 7642 has 48 cores with 96 threads and clocks with a maximum frequency of 3.30 GHz. The CPU supports up to GB of memory in 8 memory channels. The AMD EPYC 7642 was released in Q3/2019.

The Intel Xeon W-3225 has 8 CPU cores and can calculate 16 threads in parallel. The clock frequency of the Intel Xeon W-3225 is 3.70 GHz (4.40 GHz) while the AMD EPYC 7642 has 48 CPU cores and 96 threads can calculate simultaneously. The clock frequency of the AMD EPYC 7642 is at 2.30 GHz (3.30 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 W-3225 or AMD EPYC 7642 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 W-3225 can use up to 1024 GB of memory in 6 memory channels. The maximum memory bandwidth is 128.1 GB/s. The AMD EPYC 7642 supports up to GB of memory in 8 memory channels and achieves a memory bandwidth of up to 51.2 GB/s.

The thermal design power (TDP for short) of the Intel Xeon W-3225 is 160 W, while the AMD EPYC 7642 has a TDP of 225 W. The TDP specifies the necessary cooling solution that is required to cool the processor sufficiently.

The Intel Xeon W-3225 is manufactured in 14 nm and has 16.50 MB cache. The AMD EPYC 7642 is manufactured in 7 nm and has a 256.00 MB cache.
