AMD 3D V-Cache Boosts RDNA 2 iGPU On Ryzen 9 7950X3D By Over 4x Versus 7950X CPU

wccftech.com:

AMD's Ryzen 9 7950X3D CPU's integrated GPU seems to get a nice boost in gaming performance thanks to the 3D V-Cache technology.

The AMD Ryzen 7000 Desktop CPUs come with an entry-level RDNA 2 iGPU that incorporates just 2 compute units or 128 stream processors.  These cores run at a base clock speed of 400 MHz and a graphics frequency of 2200 MHz. Offering up to 0.563 TFLOPs of 563 GFLOPs of compute power, these chips deliver slightly better GPU performance than the Nintendo Switch which is rated at 500 GFLOPs.

We have already seen how these chips perform, stock and overclocked, on the standard Ryzen 7000 Desktop CPUs. PCMag took the iGPU on the newly released Ryzen 7000X3D CPUs to the test & the results are very fascinating, to say the least. The benchmarks done in games show a massive 4.3 times performance gain at 720p and up to 4 times at 1080p versus the non-3D V-Cache CPUs.

Games used for testing included F1 2022, Total War: Three Kingdoms, Tomb Raider, and Bioshock Infinite. While these performance figures are still not on par with Intel's iGPUs featured on its own desktop lineup, this radical improvement in performance shows the benefits that 3D V-Cache can bring to APUs.

We know that AMD's APUs feature some really strong iGPUs or integrated graphics. AMD will be bringing up to 12 RDNA 3 compute units on its latest Ryzen 7040 "Phoenix" APU lineup on laptops. While there is no desktop release imminent, we might see a future AMD desktop lineup that also incorporates RDNA 3 or enhanced GPU sub-sections on the same monolithic die. Considering just how bandwidth-starved these iGPUs are, a singular stack of 3D V-Cache such as the ones on Ryzen 7000 X3D
