AMD Radeon Pro SSG Pairs Polaris GPU with 1TB of On-board Memory
During their Capsaicin Siggraph 2016 event, AMD has introduced an interesting Radeon Pro product, the Radeon Pro SSG (Solid State Graphics). This new professional card includes two PCIe 3.0 M.2 slots that can be utilized to pair a Polaris GPU with up to a terabyte of on-board solid state storage.
At this point, we don’t exactly know how the slots will be attached to the GPU: whether this involves a PCIe switch or it’s wired directly. But whatever it is, the AMD Radeon Pro SSG massively increases the amount of local storage available on the card.
According to AMD, the purpose is to add an additional tier of storage to deal with the workset size limitations of current professional graphics cards. AMD’s top of the line card features 32GB of memory, which is a fair amount, but it is very limiting when it comes to analyzing large datasets.
In the past, if you wanted to use more memory than was available in your GPU’s frame buffer, you would have to use your system memory which adds a lot of latency and could degrade your performance. Obviously, the Radeon Pro SSG is not as fast as the GPU’s on-board GDDR5 VRAM, but it offers much greater performance compared to a GPU that is using the system memory configurations.
AMD claims that the Radeon Pro SSG is capable of scrubbing through 5K videos in real-time at 90 FPS. Currently, we don’t know what kind of memory this new GPU will be using but it is very likely to be NAND or 3D-NAND.
AMD Radeon Pro SSG is available for purchase, but only in beta at a whopping price of US $10,000.
