To see what's consumed, we have to measure real-world performance with frametime analysis. This means that the application has asked for the VRAM allocation – some games take an “as much as I can get” approach – but doesn't also mean that the allocated resources are consumed. The VRAM metric reported by GPU-Z and other tools is almost always a representation of VRAM requested, not actual VRAM utilization by the game. In these guides, and elsewhere on the site, one of our examined metrics is measured VRAM request size. The Witcher 3 Graphics Optimization Guide We've run several game graphics optimization guides in the past, including the below:Ĭall of Duty: Black Ops III Graphics Optimization Guide That content contains the complete charts, where this content only presents two cards. Should you like to see results from other neighboring video cards, like the GTX 1070, 970, or R9 390X, please bounce over to our RX 480 Review. For today, it's a single RX 480 GPU we're benchmarking, looking only into 4GB vs. This is something we will test as more cards become available to us. CrossFire RX 480 8GB cards may exaggerate some of our results by way of increasing computational ability but retaining a lower VRAM capacity. Note also that CrossFire RX 480 4GB cards vs. That deserved to be pointed out because, although the card should be indicative of “real” 4GB RX 480 performance, there is always a chance something is different – even if slightly. To this end, we're actually testing the same graphics card twice, just once before the VBIOS flash and once after. The press sample has flashable VBIOS that can “convert” the card into a 4GB model, thereby dropping the memory clock to 1750MHz from 2000MHz and reducing VRAM capacity. We've got two RX 480s, but they're both 8GB models: A retail card and a press sample.
