Poor AMD. They know the windo for raytracing is nearly up, and they haven't caught up. Within on or two more generations of nvidia cards this will be very much the norm for PC development and leap frog it again over consoles, so AMD need to catch up....they saw far from it.
They’re almost always behind in tech, but I don’t think it’s even been as worse as now with Nvidia going nuts with RT and ML
The thing is they also have to catch up in ML too. While peoples are still flabbergasted how it’s possible for cyberpunk 2077 to have path tracing due to the witchcraft that is ReSTIR (RTXDI), Nvidia is already researching the next step with NRC, neural radiance cache, using AI for even faster performances.
They’re not sitting on their laurels
AMD RT is just a generation behind Nvidia, so they are not that far behind. The issue with AMD, is that RT is its least focused on and developed tech in their GPUs.
On a RT performance per CU basis, it’s worse than Turing. Enable path tracing and Mid range Turing, while having shit performances, is also in the realm of shut performances that a 7900XTX will see 9 fps at 3840x1600 FSR balanced.
It’s hard to find direct comparison with Turing because those users are often with older CPUs too, but it’s not even 3060 territory, somewhere in mid range Turing, for a LOT more CUs
They are doing this stupid thing on focusing on raster performance so that picks up the slack of their RT shortcomings. Whereas what they need to do is an Nvidia, and that's what they seem to not what to do. Remember the 20 series? That was Nvidia leaving raster mostly untouched from the 10 series cards but building AI and RT tech into their GPUs. AMD needs to do the same.
Yeah
Their engineering decision for hybrid RT/rasterization pipeline to save silicon area and complexity to get MORE rasterization made sense. But they also never really got the advantage there either by huge margins. Nvidia has reportedly ~25% of silicon dedicated to RT and ML and they still managed to trade blows within a few % in rasterization too on a worse node (ampere). Now a 4080’s 379mm^2 is a few % difference with AMD flagship that has 529mm^2 total
So yeah, that solution is hitting a wall soon. Intel is more of a threat by catching up in RT rapidly (on paper, their drivers don’t make sense with path tracing games).
