AMD RX-421ND vs AMD EPYC Embedded 3251

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 AMD EPYC Embedded 3251 clocks with 2.50 GHz (3.10 GHz), has 8 CPU cores and can calculate 16 threads in parallel.

Processors with the support of artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors. Algorithms for ML improve their performance the more data they have collected via software. ML tasks can be processed up to 10,000 times faster than with a classic processor.

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 AMD EPYC Embedded 3251 supports a maximum of GB of memory with a maximum memory bandwidth of 42.7 GB/s enabled.

The AMD RX-421ND has a TDP of 35 W. The TDP of the AMD EPYC Embedded 3251 is 55 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 AMD EPYC Embedded 3251 is at 20.00 MB. The processor is manufactured in 14 nm.
