Intel Xeon Silver 4509Y vs Intel Xeon Gold 6434H

In this CPU comparison, we compare the Intel Xeon Silver 4509Y and the Intel Xeon Gold 6434H and use benchmarks to check which processor is faster.

We compare the Intel Xeon Silver 4509Y 8 core processor released in Q4/2023 with the Intel Xeon Gold 6434H which has 8 CPU cores and was introduced in Q1/2023.

The Intel Xeon Silver 4509Y is a 8 core processor with a clock frequency of 2.60 GHz (4.10 GHz). The processor can compute 16 threads at the same time. The Intel Xeon Gold 6434H clocks with 3.70 GHz (4.10 GHz), has 8 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 4096 GB of memory in a maximum of 8 memory channels is supported by the Intel Xeon Silver 4509Y, while the Intel Xeon Gold 6434H supports a maximum of 4096 GB of memory with a maximum memory bandwidth of 307.2 GB/s enabled.

The Intel Xeon Silver 4509Y has a TDP of 125 W. The TDP of the Intel Xeon Gold 6434H is 195 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The Intel Xeon Silver 4509Y has 22.50 MB cache and is manufactured in 10 nm. The cache of Intel Xeon Gold 6434H is at 22.50 MB. The processor is manufactured in 10 nm.
