AMD RX-421ND vs Intel Xeon Platinum 8280M

In this CPU comparison, we compare the AMD RX-421ND and the Intel Xeon Platinum 8280M and use benchmarks to check which processor is faster.

We compare the AMD RX-421ND 4 core processor released in Q4/2015 with the Intel Xeon Platinum 8280M which has 28 CPU cores and was introduced in Q3/2019.

The AMD RX-421ND is a 4 core processor with a clock frequency of 2.10 GHz (3.40 GHz). The processor can compute 4 threads at the same time. The Intel Xeon Platinum 8280M clocks with 2.70 GHz (4.00 GHz), has 28 CPU cores and can calculate 56 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 GB of memory in a maximum of 2 memory channels is supported by the AMD RX-421ND, while the Intel Xeon Platinum 8280M supports a maximum of GB of memory with a maximum memory bandwidth of 140.7 GB/s enabled.

The AMD RX-421ND has a TDP of 35 W. The TDP of the Intel Xeon Platinum 8280M is 205 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The AMD RX-421ND has 2.00 MB cache and is manufactured in 28 nm. The cache of Intel Xeon Platinum 8280M is at 38.50 MB. The processor is manufactured in 14 nm.
