Intel Xeon Platinum 8354H vs Intel Atom C3955

In this CPU comparison, we compare the Intel Xeon Platinum 8354H and the Intel Atom C3955 and use benchmarks to check which processor is faster.

We compare the Intel Xeon Platinum 8354H 18 core processor released in Q2/2020 with the Intel Atom C3955 which has 16 CPU cores and was introduced in Q3/2017.

The Intel Xeon Platinum 8354H is a 18 core processor with a clock frequency of 3.10 GHz (4.30 GHz). The processor can compute 36 threads at the same time. The Intel Atom C3955 clocks with 2.10 GHz (2.40 GHz), has 16 CPU cores and can calculate 16 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 1146 GB of memory in a maximum of 6 memory channels is supported by the Intel Xeon Platinum 8354H, while the Intel Atom C3955 supports a maximum of 256 GB of memory with a maximum memory bandwidth of 38.4 GB/s enabled.

The Intel Xeon Platinum 8354H has a TDP of 205 W. The TDP of the Intel Atom C3955 is 32 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The Intel Xeon Platinum 8354H has 24.75 MB cache and is manufactured in 14 nm. The cache of Intel Atom C3955 is at 16.00 MB. The processor is manufactured in 14 nm.
