AMD Radeon R9 390X rumored to have truly next-gen 4096-bit memory bus

AMD rumored to inject 4096-bit memory bus onto its next-gen Radeon R9 390X, would result in 640GB/sec memory bandwidth

Here we are again, another post about the AMD Radeon R9 390X, but this time we have some even more exciting news. There's more details leaking out on the codename Fiji XT board, thanks to a listing in the SiSoft Sandra benchmark database.

If the details are true, and right now we're classing them as rumors, we could expect the Radeon R9 390X to feature a whopping 4096 stream processors, with 64 compute units and 256 texture units - but the best bit, we've saved until last: a massive, game-changing 4096-bit memory bus. This insane jump in memory bus specs will have been a result of the HBM technology we reported on a little while ago now, with a 1024-bit input/output interface.

We should see the first R9 390X cards with 4GB of RAM, but 8GB of VRAM will be seen on these GPUs very quickly. If we do see four, first-generation HBM DRAM chips with a 4096-bit memory bus operating at around 1.25GHz, we can expect a huge memory bandwidth of 640GB/sec. Considering the still-fresh, and kick-ass NVIDIA GeForce GTX 980 has a 256-bit memory bus with 224GB/sec of bandwidth, AMD would be killing it at high-res. 4K and beyond would see AMD leaping ahead, which is something they need right now.

With 4096 stream processors and an insanely wide memory bus, it would be the highest bandwidth ever used on a single GPU. If these specs are correct, it means that AMD should have the fastest video card on the market, by a nice amount - even more so when it comes to high-res, and multi-monitor gaming.
