AMD makes its next step in GPU dominance with Vega

By: Anthony Garreffa | AMD Radeon GPU in Video Cards | Posted: Jan 5, 2017 11:49 pm

See. I told you - look at that headline: "the world's most scalable GPU memory architecture". Say what?! How is this so? Is it just HBM2? No - it's not just that, as AMD have always been a company that strives towards next generation technologies, and that's what Radeon Vega introduces.

 

 

Introducing High-Bandwidth Cache

Everyone until now has thought that AMD has just worked on a refreshed GPU architecture and slapped HBM2 technology inside, but it's not quite that easy - a large part of Vega is the new High-Bandwidth Cache.

 

 

We also have HBM2 technology, which provides up to 2x bandwidth per pin - a huge 1024GB/sec (1TB/sec) of VRAM, ready for your current, and next-gen games.

HBM2 provides some massive savings on the PCB of graphics cards, with a 50% smaller footprint when compared to GDDR5.

 

Next up, we have the High-Bandwidth Cache Controller, which has up to 512TB (yes, that's terabytes) of virtual address space.

This allows for what AMD explains as "adaptive, fine-grained data movement" - remember, Vega isn't here for gamers only, but for supercomputers and massive systems that work on super-complex dataloads.

 

If we look at 4K gaming on Ultra settings with titles like Fallout 4 and The Witcher 3, the difference between 'allocated' and 'accessed' VRAM - there's a large difference. You don't need as much VRAM as you think, because the game will simply chew up a bunch of it - but only uses around half of that in real-world usage.
