During their Vega Next-Generation GPU Architecture preview event earlier in the day, AMD shared a whole lot of high-level details for their new graphics design. As expected, the new architecture design features numerous under the hood improvements along with the use of HBM2. Luckily for us, AMD also showed off an unnamed Vega GPU chip, with Raja Koduri holding it up to the crowd.
One of the first things you’ll notice about this unknown Vega GPU is that it features 2 stacks of HBM2. Given the 8x capacity increase, we could be seeing anywhere up to 16GB of HBM2 on this specific chip. It’s also most likely Vega 10 which is the first of the new architecture to arrive.
Looking more closely at the chip, it appears to about 530-560mm2 which is somewhat larger than the GP102 powering the Titan X Pascal but less than the monster GP100 Pascal flagship. Given the immense size we are seeing, I suspect Vega 10 may be the top end chip that will do battle with the Titan X while Vega 11 will be a lower end model targeting the GTX 1080. With HBM2, this GPU likely features up to 512GB/s memory bandwidth due to the improved speeds over HBM1.
Finally, AMD also showed off a demo of DOOM running at 4K at Ultra settings on an unspecified Vega GPU. It has been confirmed that the GPU being used for the demo featured 8GB of memory so it will be interesting to see what AMD will be bringing to the table first. While no release date has been given out thus far, it is for sure 2017 and hopefully sooner rather than later.
