16GB HBM2 @ 1TB/sec
There have been lofty expectations around HBM2 performance, but ultimately, AMD disappointed with the Radeon RX Vega 64. 8GB wasn't enough for the main argument, with NVIDIA having 11GB of RAM on the GeForce GTX 1080 Ti at the time, but the new HBM2 available on Radeon VII really amps things up.
AMD has a huge 16GB of HBM2 on the Radeon VII with a huge 1TB/sec of memory bandwidth thanks to its super-wide 4096-bit memory bus. AMD isn't aiming the Radeon VII at casual gamers, so the 16GB being fully utilized will be for a small handful.
I normally would have to explain this part but AMD provided a great infographic in the last 8 hours or so before the review went live. Here we can see that there are games on the market that consume up to 12.9GB of framebuffer. NVIDIA's closest competitor to the new Radeon VII is the GeForce RTX 2080 which has 8GB of GDDR6, compared to the larger 16GB of much faster HBM2 on the Radeon VII.
Most of these games combined have tens of millions of players, millions of which now have a Radeon graphics card capable of 4K 60FPS in most games, and the large 16GB VRAM to back it up. I will be exclusively running native 8K at 7680 x 4320 on my Dell UP3218K monitor in a follow up article in a couple of days, to see if we can really stretch out that 16GB of HBM2.
Content Creation Monster
16GB of ultra-fast HBM2 doesn't just accelerate games, it would better serve as a content creation monster where it can smash through 4K and 8K video encoding faster than ever before.
Adobe Premiere is used by millions of content creators, even here at TweakTown we're in it every day of the week. AMD's previous-gen Radeon RX Vega 64 was already a good card, but 8K editing isn't easy on a GPU... any GPU. The 16GB of HBM2 on the Radeon VII really comes in handy, offering up some good improvements over the RX Vega 64 and RTX 2080.
But when you look at compute performance in something like LuxMark, you really see how much that 16GB of super-fast HBM2 at 1TB/sec comes into play. We're looking at over 60% more results on the Radeon VII over the RX Vega 64 and RTX 2080 graphics cards.
Blender user? Yeah, you'll enjoy the Radeon VII too.
The same 30% or so improvement over the 8GB HBM2 inside of the Radeon RX Vega 64, and the same performance as the RTX 2080.
