Core i9-12900KF, Core i7-12700K and Core i5-12600 in a workstation test with amazing results and an old weakness | Part 2

Hi, you guys at IgorsLab are a lifesaver. A big thanks to you for this article. It would also be of highly interest to see if DDR4 vs DDR5 has any impact on the i9-12900 performance as well. Asking as many people, like me, have invested in 64-128GB DDR4 memory kits and it would be really interesting to see if one would still be able to use them with the i9-12900 without any performance penalty, in my case SolidWorks, or if it is worth investing in a new set of the much pricier DDR5.

A big thanks again,
Peter

So let's wait for a 2nd run :)

But I need a short rest.

Hi again, Any updates? Eager to see if DDR4 vs DDR5 has any impact on SolidWorks rebuild time as it is such pain in the ass :cool:

Going for DDR4 motherboard and the 12900K today as DDR5 memories aren't that easy to get around here, and must be imported, and i need the build now for my work. It will do till Raptor Lake enters the scene q3 next year and DDR5 and m.2 PCIe 5.0 are more matured.

Strange indeed. 12900K on a Gigabyte Z690i Aorus Ultra DDR4, all settings by default except for XMP.
My setup scores only 1.90 points in CPU Rebuild Composite compare to your 2.89. Huge difference indeed. So DDR5 seems yo speeds up rebuild time in SolidWorks dramatically. I tested to down clock my DDR4 to 2133Mhz only and rebuild time score surprisingly INCREASED to 2.04 points :-O
Other benchmarks are in line with other testers online...
