Remember the Vega 12? Well, a Geekbench listing has appeared that has got people talking about the GPU found in the Radeon Pro Vega 16 and Radeon Pro Vega 20, the dedicated GPU option for last year's 15-inch MacBook Pro. Initially brought to our attention by prolific leaker @KOMACHI_ENSAKA, the GPU has now seemingly found its way into a desktop setup.
Paired with an ASUS RAMPAGE IV FORMULA motherboard and an Intel Core i7-3960X CPU, the GPU, codenamed the GFX904, has 16 Compute Units (CUs) and 4 GB of High-Bandwidth 2 (HBM2) memory just as the Radeon Pro Vega 16 does. However, Geekbench reports the GFX904 as boosting up to 1.49 GHz, which is way above what either the Radeon Pro Vega 16 or Vega 20 can reach.
There are plenty of unanswered questions here, not least of which why a mobile GPU is being tested on a desktop motherboard. In a corresponding Reddit thread, people have suggested that AMD could be working on a new Desktop GPU, a re-badged mobile GPU or it even being part a high-end APU.
Either way, we cannot currently see a reason why AMD would resurrect a 14 nm chip when it apparently has newer 7 nm alternatives on the way. Perhaps we have missed something, but this seems like one of the more curious GPU-related things to have appeared on Geekbench recently.
