AMD EPYC 9754 vs AMD Athlon II X4 645

The AMD EPYC 9754 is a 128 core processor with a clock frequency of 2.25 GHz (3.10 GHz). The processor can compute 256 threads at the same time. The AMD Athlon II X4 645 clocks with 3.10 GHz, has 4 CPU cores and can calculate 4 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 6144 GB of memory in a maximum of 12 memory channels is supported by the AMD EPYC 9754, while the AMD Athlon II X4 645 supports a maximum of 16 GB of memory with a maximum memory bandwidth of 21.3 GB/s enabled.

The AMD EPYC 9754 has a TDP of 360 W. The TDP of the AMD Athlon II X4 645 is 95 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The AMD EPYC 9754 has 256.00 MB cache and is manufactured in 5 nm. The cache of AMD Athlon II X4 645 is at 2.00 MB. The processor is manufactured in 45 nm.
