AMD Radeon R9 Fury X review • Eurogamer.net
vram e micro-stuttering
There's a simple rule of thumb developers have been telling us for years now - when it comes to making a GPU purchase, the more VRAM you have onboard and the faster it is, the better. This puts AMD in a difficult position with the R9 Fury X. HBM is expensive, and while it's ultra-fast, current designs are limited to 4GB of RAM. Meanwhile, Nvidia ships the GTX 980 Ti with 6GB of GDDR5, while AMD's own R9 390 and 390X have a colossal 8GB of onboard memory.The question is whether 4GB is enough, or if current and future titles need more. Our benchmarks typically omit multi-sampling anti-aliasing (a traditionally large drain on memory) so across 1080p, 1440p and 4K, we don't tend to see anything above 4GB of RAM making much in the way of difference right now. In future, that might be entirely different, of course.
However, one of our tests does indeed push memory to the limits - Assassin's Creed Unity, running at 4K on very high settings with FXAA. And here's where we see some interesting data. Click on the images in this sidebar, and note the latency spikes on the red and orange lines (the rectangular drops on the right graph) representing the Fury X and the R9 290X - the only 4GB cards in the comparison. Then note the lack of such spikes on the R9 390X and GTX 980 Ti, both of which have much more than 4GB of RAM.
If there's a smoking gun here, it's that we are running 290X and 390X on the same driver - that's the same hardware effectively, the only difference coming from clock-speed and VRAM allocation. If more VRAM wasn't helpful here, we should expect the R9 390X to stutter just like the Fury X and the 290X, but it doesn't. This may be indicative that VRAM - or lack of it - is the culprit for the latency spikes we do see, even though the Fury X has delta compression technology that the 290X lacks, which should help to make its 4GB go further.Right now, we feel that 4GB isn't a deal-breaker for the Fury X - most games fit within that allocation relatively comfortably as the benchmarks attest, though we do shy away from Shadow of Mordor's ultra textures (as the developer does not recommend them for sub-6GB cards). However, based on our discussions with developers, we feel that VRAM utilisation is only moving in one direction - upwards - and that's a consequence of the lavish amount of unified memory available on the current generation of consoles dictating the trend of development.
As one well-placed developer told us recently: "The harder we push the hardware and the higher quality and the higher res the assets, the more memory we'll need and the faster we'll want it to be. Our games currently in development are hitting memory limits on the consoles left, right and centre now - so memory optimisation is on my list pretty much constantly."
