Intel Xeon Platinum 8280M vs Intel Core 2 Quad Q9400s

Intel Xeon Platinum 8280M or Intel Core 2 Quad Q9400s - which processor is faster? In this comparison we look at the differences and analyze which of these two CPUs is better. We compare the technical data and benchmark results.

The Intel Xeon Platinum 8280M has 28 cores with 56 threads and clocks with a maximum frequency of 4.00 GHz. Up to GB of memory is supported in 6 memory channels. The Intel Xeon Platinum 8280M was released in Q3/2019.

The Intel Core 2 Quad Q9400s has 4 cores with 4 threads and clocks with a maximum frequency of 2.66 GHz. The CPU supports up to 16 GB of memory in 2 memory channels. The Intel Core 2 Quad Q9400s was released in Q1/2009.

The Intel Xeon Platinum 8280M has 28 CPU cores and can calculate 56 threads in parallel. The clock frequency of the Intel Xeon Platinum 8280M is 2.70 GHz (4.00 GHz) while the Intel Core 2 Quad Q9400s has 4 CPU cores and 4 threads can calculate simultaneously. The clock frequency of the Intel Core 2 Quad Q9400s is at 2.66 GHz.

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.

The Intel Xeon Platinum 8280M or Intel Core 2 Quad Q9400s has integrated graphics, called iGPU for short. The iGPU uses the system's main memory as graphics memory and sits on the processor's die.

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.

The Intel Xeon Platinum 8280M can use up to GB of memory in 6 memory channels. The maximum memory bandwidth is 140.7 GB/s. The Intel Core 2 Quad Q9400s supports up to 16 GB of memory in 2 memory channels and achieves a memory bandwidth of up to 17.1 GB/s.

The thermal design power (TDP for short) of the Intel Xeon Platinum 8280M is 205 W, while the Intel Core 2 Quad Q9400s has a TDP of 65 W. The TDP specifies the necessary cooling solution that is required to cool the processor sufficiently.

The Intel Xeon Platinum 8280M is manufactured in 14 nm and has 38.50 MB cache. The Intel Core 2 Quad Q9400s is manufactured in 45 nm and has a 6.00 MB cache.
