    [News] Performance Penalty from Enabling HDR at 4K Lower on AMD Hardware Versus NVIDI

    The folks over at have took it into their hands to study exactly how much of an impact >(if any) would activating HDR on a 4K panel affect performance cross different hardware configurations. Supposedly, HDR shouldn't impose any performance penalty on GPUs that were designed to already consider that output on a hardware level; however, as we know, expectations can sometimes be wrong.

    Comparing an AMD Vega 64 graphics card against an NVIDIA GeForce 1080, the folks ate Computerbase arrived at some pretty interesting results: AMD hardware doesn't incur in as big a performance penalty (up to 2%) as NVIDIA's graphics card (10% on average) when going from standard SDR rendering through to HDR rendering. Whether due to driver-level issues or not is unclear; however, it could also have something to do with the way NVIDIA's graphics cards process 4K RGB signals by applying color compression down to reduced chroma YCbCr 4:2:2 in HDR - an extra amount of work that could reduce frame rendering. However, it's interesting to note how Mass Effect Andromeda, one of the games NVIDIA gave a big marketing push for and that showcased HDR implementation, sees no performance differential on the green hardware.I also seem to remember some issues regarding AMD's frame time performance being abysmal - looking at Computerbase's results, howveer, those times seem to be behind us.
