AMD Ryzen 7 7840S vs AMD EPYC 9554P

In this CPU comparison, we compare the AMD Ryzen 7 7840S and the AMD EPYC 9554P and use benchmarks to check which processor is faster.

We compare the AMD Ryzen 7 7840S 8 core processor released in Q2/2023 with the AMD EPYC 9554P which has 64 CPU cores and was introduced in Q4/2022.

The AMD Ryzen 7 7840S is a 8 core processor with a clock frequency of 3.30 GHz (5.10 GHz). The processor can compute 16 threads at the same time. The AMD EPYC 9554P clocks with 3.10 GHz (3.75 GHz), has 64 CPU cores and can calculate 128 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 256 GB of memory in a maximum of 2 memory channels is supported by the AMD Ryzen 7 7840S, while the AMD EPYC 9554P supports a maximum of 6144 GB of memory with a maximum memory bandwidth of 460.8 GB/s enabled.

The AMD Ryzen 7 7840S has a TDP of 15 W. The TDP of the AMD EPYC 9554P is 360 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The AMD Ryzen 7 7840S has 24.00 MB cache and is manufactured in 4 nm. The cache of AMD EPYC 9554P is at 320.00 MB. The processor is manufactured in 5 nm.
