CPU Pro Reviews Workstations

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

AutoCAD 2021 with the Cadalyst Benchmark Suite

Well, AutoCAD has never really been AMD’s domain, but Ryzen 5000 was able to catch up with Comet Lake S for the first time and even take a slight lead. It was even still good enough for Rocket Lake. And then came Alder Lake. Unfortunately, AutoCAD is extremely CPU-intensive and there is very little parallelization to be done in the normal workspace. It is often what a few cores are capable of that counts. There are hardly any differences between the two PL1 variants of the i9-12900KF, but to the rest of the test field outside of the blue bars. That’s where it gets really declassifying.

In 2D and in 3D, the RTX A6000 is still almost limited by the CPU even in Ultra HD, although things are looking a bit better with Alder Lake.

The faster of the i9-12900KF has a whopping 38 percentage point lead over the Ryzen 9 5950X here, and even the i5-12600K is significantly faster than the i9-11900K and all other Ryzen CPUs. The score is made up of various individual ratings, all of which go to the i9-12900KF and the i7-12700K. The smaller i5-12600K still has enough power to tame the CPUs with the red bars, at least in most benchmark parts.

Partial benchmarks of the Cadalyst

Let’s now take a look at the individual results, where the disk performance of ADL on the Z690 board can also positively surprise. I don’t think we need to write anything else about 3D and 2D, that’s self-explanatory.

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...
