AMD’s Ryzen 9 7950X3D debuted earlier this week to vital acclaim because it dethroned Intel’s Core i9-13900K because the greatest CPU for gaming when paired with a discrete GPU. Nonetheless, PC Magazine reported in its 7950X3D evaluate that AMD’s 3D V-Cache tech, the chip-stacking expertise behind the large features in gaming efficiency, resulted in a 3x to 4x improve within the efficiency of the tiny built-in GPU onboard over the usual Ryzen 9 7950X. PC Magazine’s outcomes have been later picked up and cited by various different publications who clearly didn’t do their very own testing.

Whereas this would not be very thrilling with the essential RDNA 2 iGPU aboard the Ryzen 7000 collection processors, that kind of efficiency achieve would theoretically be phenomenal if the tech have been utilized to an APU, setting lovers’ hopes alight with the information. Nonetheless, we put the efficiency claims to the check by means of our personal battery of iGPU checks and located that the cited check outcomes look like in error.

Once we first learn PC Magazine’s report and the next tales about it by different retailers, the outcomes appeared questionable due to some technical features. First, each CPUs have the identical primary graphics engine, and the performance-boosting cache is situated on simply one of many 7950X3D’s two compute chiplets. 

Nonetheless, the iGPU resides on the I/O die and is a self-contained unit with its personal L2 cache. As such, it would not entry the L3 cache on the compute die in any significant means (diagram additional under within the article). Due to this fact, any efficiency features could not come from further cache bandwidth.

Quite, any improve must come from the 7950X3D’s phenomenal features in CPU compute efficiency. That may push the GPU even more durable, however the CPU is not the limiting issue. The Ryzen 9 7950X3D’s iGPU solely has two RDNA 2 compute items (CU) at its disposal, so it would not have the required horsepower to profit from elevated reminiscence bandwidth or a sooner CPU. This unit is totally GPU compute-bound.

Yet one more fast tidbit. AMD has been fairly clear that the Ryzen 7000-series’ new iGPU is not meant for any kind of significant gaming. As an alternative, it is meant to offer primary display-out capabilities for troubleshooting and the like in addition to sufficient efficiency for watching movies and doing primary workplace duties.
