Intel Core 2 Quad Q9400s vs Intel Xeon D-2161I

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 D-2161I clocks with 2.20 GHz (3.00 GHz), has 12 CPU cores and can calculate 24 threads in parallel.

Processors with the support of artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors. Algorithms for ML improve their performance the more data they have collected via software. ML tasks can be processed up to 10,000 times faster than with a classic processor.

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 D-2161I supports a maximum of 512 GB of memory with a maximum memory bandwidth of 68.2 GB/s enabled.

The Intel Core 2 Quad Q9400s has a TDP of 65 W. The TDP of the Intel Xeon D-2161I is 90 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 D-2161I is at 16.50 MB. The processor is manufactured in 14 nm.
