AMD EPYC 9354 vs Intel Atom x7405C

In this CPU comparison, we compare the AMD EPYC 9354 and the Intel Atom x7405C and use benchmarks to check which processor is faster.

We compare the AMD EPYC 9354 32 core processor released in Q4/2022 with the Intel Atom x7405C which has 4 CPU cores and was introduced in Q2/2024.

The AMD EPYC 9354 is a 32 core processor with a clock frequency of 3.25 GHz (3.80 GHz). The processor can compute 64 threads at the same time. The Intel Atom x7405C clocks with 2.20 GHz (3.40 GHz), has 4 CPU cores and can calculate 4 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 6144 GB of memory in a maximum of 12 memory channels is supported by the AMD EPYC 9354, while the Intel Atom x7405C supports a maximum of 32 GB of memory with a maximum memory bandwidth of 38.4 GB/s enabled.

The AMD EPYC 9354 has a TDP of 280 W. The TDP of the Intel Atom x7405C is 12 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The AMD EPYC 9354 has 288.00 MB cache and is manufactured in 5 nm. The cache of Intel Atom x7405C is at 8.00 MB. The processor is manufactured in 10 nm.
