We can better compare what are the technical differences between the two processors. The processor Intel Xeon W-2145 has more cores, that the maximum frequency of the Intel Xeon W-2145 is superior, that the heat dissipation power of the Intel Core i5-8400 is smaller. Both were produced during the same year.

Note: prices can change over time. They are not updated regularly. Shipping costs have not been integrated.

Performance comparison between the two processors, for this we consider the following benchmarking softwares: Geekbench 4, PassMark and Cinebench R15.

Geekbench 4:

Processeur Geekbench 4 – Score multi-core & single-core – Windows 64-bit
Intel Xeon W-2145  5 164
 27 503
Intel Core i5-8400  4 765
 18 154

Geekbench 4 is a complete benchmark platform with several types of tests, including data compression, image encryption, AES encryption, SQL encoding, HTML rendering, PDF rendering, Matrix calculation, Fast Fourier Transformation, 3D object simulation, photo editing, memory testing. This allows us to better visualize the respective power of these two chips. For each result, we took an average of 250 values on the famous benchmark software.

On the single-core side, the difference is 8%. In multi-core, the differential gap is 51%.


Processeur PassMark – CPU Mark & single thread
Intel Xeon W-2145  2,525
Intel Core i5-8400  2,335

PassMark is a benchmarking software that performs several tests including prime numbers, integers, floating point, compression, physics, extended instructions, encryption, sorting. Higher is the score, bigger is the power of the computer.

On PassMark, there is a difference of 8% in single-core. On the multi-core side, the gap is 70%.

Cinebench R15:

Processeur Cinebench R15 – Score
Intel Xeon W-2145  177
Intel Core i5-8400  169

Cinebench R15 allows to evaluate the performance of a CPU by rendering a photorealistic 3D scene. The scene has 2,000 objects, 300,000 polygons, antialiasing, uses sharp and fuzzy reflections, bright areas, procedural shaders, shadows, etc. Faster is the rendering of the scene created, more powerful is the PC, with a high number of points.

On this software, there is a difference of 5% in single-core. On the multi-core side, the gap reaches 76%.
