3D V-Cache appears to do wonders for the iGPU in AMD’s flagship Ryzen 7000 Series processor. According to a set of integrated graphics benchmarks shared by PCMag, the Ryzen 9 7950X3D features dramatically increased iGPU performance versus its standard Zen 4 sibling thanks to the inclusion of the additional cache, with gains as high as 4x in the 720p and 1080p resolutions. The Ryzen 9 7950X3D features 144 MB of total cache, while the Ryzen 9 7950X features 80 MB of total cache. Both were launched at an SEP of $699.
From a PCMag report:
As it stands, the Ryzen 9 7950X3D’s IGP has just 128 stream processors, eight texture-mapping units (TMUs), and four render output units (ROPs) clocked at 2,200MHz. This is identical to the Ryzen 9 7950X, but the Ryzen 9 7950X3D’s IGP also benefits from the added 3D V-Cache. As you can see from the test results, the Ryzen 9 7950X3D’s IGP blows its fraternal twin out of the water with three to four times as much performance.
It’s jaw-dropping to see how much more competitive the Ryzen 9 7950X3D’s IGP is against the Core i9-13900K’s, too. The Core i9-13900K’s IGP is still faster in most tests but, at least in F1 22 at 720p, the 7950X3D’s IGP takes the lead.
To be clear, from the specs we can tell with certainty that the IGP inside of the competing Intel chips here is the faster IGP, but like most IGPs it is held back by bandwidth and memory limitations. These limitations undoubtedly affect the AMD Ryzen 9 7950X, as well, and they may be hitting the Ryzen 9 7950X3D too, but to a far lesser degree.
