AMD Radeon Vega 12 and Vega 20 Listed in Ashes Of The Singularity Database
Back at Computex, AMD showed a demo of their Vega 20 graphics processor, which is produced using a refined 7 nanometer process. We also reported that the chip has a twice-as-wide memory interface, effectively doubling memory bandwidth, and alsomaximum memory capacity. The smaller process promises improvements to power efficiency, which could let AMD run the chip at higher frequencies for more performance compared to the 14 nanometer process of existing Vega.
As indicated by AMD during Computex, the 7 nanometer Vega is a product targeted at High Performance Compute (HPC) applications, with no plans to release it for gaming. As they clarified later, the promise of "7 nanometer for gamers" is for Navi, which follows the Vega architecture. It's even more surprising to see AOTS results for a non-gaming card - my guess is that someone was curious how well it would do in gaming.The device ID 66A0 has been never seen before and is sufficiently far away from Vega 10 (687F) to indicate that AMD treats Vega 20 as a really new product and not as a minor revision. We expect Vega 20 to be used on a Radeon Instinct card first, with 32 GB of HBM2 memory and 4096 shaders, a professional workstation card called "Radeon Pro Vega 20" could also be possible, as indicated by other leaks, but I'm skeptic whether AMD really wants to put the "20" from the GPU codename into the official marketing name, going against what they used for "Vega 64".The second card listed is Vega 12, for which very little is known. Its device ID 69A0 is also from a new, unused value range. It is rumored that Vega 12 is targeted at lower-end, mobile markets, possible to offer an alternative to Polaris. We also wouldn't be surprised to see improved power management on Vega 12, to cater better for mobile devices, which require higher energy efficiency. Please note that Vega 12 does not indicate the number of CUs (like on Vega 64 for instance), but rather represents the internal GPU codename, like Vega 10.
