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.
AMD Ryzen 9 7950X3D’s RDNA 2 iGPU Boosted By Over 4x Versus Standard 7950X CPU By 3D V-Cache
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 parts, can bring some huge performance increases.
Given what we know, the idea of seeing a Ryzen 7000-series APU, a processor with a relatively powerful IGP and the 3D V-Cache together, would be exciting. On the Ryzen 9 7950X, however, this is interesting but not particularly useful. Few folks are likely to buy the Ryzen 9 7950X intending to play games on its IGP. This makes the performance gains technologically intriguing, but mostly just a footnote.

The AMD 3D V-Cache technology has so far only been integrated into chiplet processors whereas the APUs utilize a monolithic design approach. Given the efficiency of 3D V-Cache chips for gaming, they can become an awesome platform for laptop gamers. AMD has brought the same desktop die to laptops in the form of Dragon Range “Ryzen 7045 series” but no 3D V-Cache implementation of an APU exists.
Once again, if AMD goes that route, it can be a game-changer & I believe that it might already be in consideration by the red team considering Intel’s going to bring out its own powerful iGPU architecture known as tGPU (Tiled-GPU) on next-gen Meteor Lake and Arrow Lake chips. The multi-tile and disaggregated chiplet design is supposed to carry powerful iGPUs and may also incorporate a separate cache die that directly benefits the iGPU. To tackle that, AMD has its own 3D V-Cache technology but we will wait to see how long it takes them to incorporate it in future APUs.
