Intel Core 2 Quad Q9400s vs AMD Ryzen Threadripper PRO 7945WX

In this CPU comparison, we compare the Intel Core 2 Quad Q9400s and the AMD Ryzen Threadripper PRO 7945WX 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 AMD Ryzen Threadripper PRO 7945WX which has 12 CPU cores and was introduced in Q4/2023.

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 AMD Ryzen Threadripper PRO 7945WX clocks with 4.70 GHz (5.30 GHz), has 12 CPU cores and can calculate 24 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 AMD Ryzen Threadripper PRO 7945WX supports a maximum of 2048 GB of memory with a maximum memory bandwidth of 332.8 GB/s enabled.

The Intel Core 2 Quad Q9400s has a TDP of 65 W. The TDP of the AMD Ryzen Threadripper PRO 7945WX is 350 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 AMD Ryzen Threadripper PRO 7945WX is at 76.00 MB. The processor is manufactured in 5 nm.
