Intel Core 2 Quad Q9400s vs Intel Xeon Platinum 8468H

In this CPU comparison, we compare the Intel Core 2 Quad Q9400s and the Intel Xeon Platinum 8468H and use benchmarks to check which processor is faster.

We compare the Intel Core 2 Quad Q9400s 4 core processor released in Q1/2009 with the Intel Xeon Platinum 8468H which has 48 CPU cores and was introduced in Q1/2023.

The Intel Core 2 Quad Q9400s is a 4 core processor with a clock frequency of 2.66 GHz. The processor can compute 4 threads at the same time. The Intel Xeon Platinum 8468H clocks with 2.10 GHz (3.80 GHz), has 48 CPU cores and can calculate 96 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 16 GB of memory in a maximum of 2 memory channels is supported by the Intel Core 2 Quad Q9400s, while the Intel Xeon Platinum 8468H supports a maximum of 4096 GB of memory with a maximum memory bandwidth of 307.2 GB/s enabled.

The Intel Core 2 Quad Q9400s has a TDP of 65 W. The TDP of the Intel Xeon Platinum 8468H is 330 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The Intel Core 2 Quad Q9400s has 6.00 MB cache and is manufactured in 45 nm. The cache of Intel Xeon Platinum 8468H is at 105.00 MB. The processor is manufactured in 10 nm.
