AMD’s Vega Will Double Your Usable Graphics Memory Capacity With Its Clever New High Bandwidth Cache

 

Perhaps the most intriguing and exciting of all the new bells and whistles that Vega brings to the table is its unique memory architecture and High Bandwidth Cache. The new memory architecture allows Vega GPUs to do a number of exciting new things that its predecessors can’t. One of its features in particular is impressive enough to warrant having its own discussion.

Besides handling memory traffic in a vastly more efficient fashion it also significantly cuts back on wasteful memory allocations. We go into a lot of details on how it works and why it’s quite revolutionary in our Vega graphics architecture piece, where we break it all down. We’re not going to dive into the details here, so if you want to read more about it we’d highly recommend checking out that article.

 

An 8GB Vega graphics card, just as an example, will be effectively have as much usable memory as a 16GB graphics card. It’s all thanks to the company’s brand new High Bandwidth Cache Controller at the heart of every Vega graphics chip and the way it works is quite clever. And who is better to explain it all than AMD’s top graphics man and beloved nerd Raja Koduri.

Raja Koduri – Chief Architect Radeon Technologies Group, AMD
With regards to the High Bandwidth Cache from a gaming perspective. We looked at all the modern games, the big games that push memory hard, and one of the things we noticed is the VRAM – graphics memory – utilization. We look at how much of the VRAM that the game allocates. So if the game say needs 4GB of memory when we looked at actually how much of that memory is actually used to render pixels we found that many games, actually most games, don’t use more than 50% of what they allocate.

That’s because the current/old GPU architecture doesn’t give you flexibility to move memory in fine granularity. So with Vega and with the High Bandwidth Cache and the HBC controller, for games it will utilize the amount of frame-buffer you have much more efficiently. So effectively you can think of it as Vega will be doubling your memory capacity for games.

Brad Chacos – Senior Editor,PC World
So basically a game that says it uses 4GB of VRAM right now, is in actuality using 2 and with Vega, you’re saying, it will actually allocate 2.

Exactly
