AMD Ryzen 7 9800X3D Linux Performance: Zen 5 With 3D V-Cache
For those wondering, between the prior ASUS ROG X670E GAMING WIFI motherboard and the ASRock X870E Taichi motherboard, at least under Linux there was no real CPU performance difference observed. Similarly the slightly tighter timings with the new GSKILL DDR5-6000 modules supplied as part of the AMD review kit didn't make a significant difference.
For most workloads not very sensitive to the L3 cache size, the Ryzen 7 9800X3D came in right where one would expect between the Ryzen 7 9700X and Ryzen 9 9900X.
The Ryzen 7 9800X3D with 3D V-Cache begins to flex its muscles more when hitting some of the creator workloads able to better utilize the larger cache size. With the Open Image Denoise library the Ryzen 7 9800X3D was matching the performance of the Ryzen 9 7950X3D.
The performance under OIDn is particularly enticing and not far behind Intel's flagship Arrow Lake CPU, the Core Ultra 9 285K, while costing significantly less.
Moving to the HPC-type workloads where the AMD 3D V-Cache has consistently shown to be beneficial, the OpenFOAM CFD results are very positive for the Ryzen 7 9800X3D. In fact for the small mesh size model, the Ryzen 7 9800X3D was faster than the Ryzen 9 9950X!
The 2nd Gen 3D V-Cache with the Ryzen 7 9800X3D performance in creator/HPC workloads has me very eager to see AMD EPYC Turin with 3D V-Cache as well as the presumed Ryzen 9 9900X3D series parts.
