The issue with all these discussions seems to ignore the GPU apocalypse which has meant the 6 year old GTX1060 is still at the top of the list,and it hasn't been made for years now.
In the top list of dGPUs,the non-RT capable dGPUs are at 39% of the userbase,which is nearly twice that of the RT capable dGPUs in the top list(20%). So it doesn't matter if the consoles suck at RT,because those 39% of non-RT capable dGPU suck even more,as do the vast majority of the dGPUs listed on Steam. Now if you go down the list further,it's most likely the figures get skewed in favour of non-RT capable dGPUs even more.
So 2/3 are not on RT capable dGPUs in the top 20 on Steam. Of that 20% of RT capable dGPUs,nearly 55% are made up of Turing dGPUs.
As indicated by the figures in Cyberpunk 2077,which likes Nvidia dGPUs,the RDNA2 GPUs are broadly similar to Turing dGPUs upto the RTX2080/RTX2080 Super in RT performance.
The RX6900XT is about RTX2080 Super performance in RT in Cyberpunk 2077. An RX6700XT is about RTX2060 Super/RTX2070 level RT performance.
So taking consoles into consideration,using your own 30 million number for RT capable PCs(and the recent update now says 30 million consoles),that is at least 60 million RT capable systems.
However,of that number that is around 46 million RT capable systems which this forum denotes as having subpar RT performance,because they are no better or worse than an RX6900XT,which also means almost all of the Turing range. But out of those Ampere users,a few are on an RTX3060 which doesn't have very great RT performance either,and in the realm of RDNA 2 dGPUs too. So that is easily over 50 millon out of those systems with subpar RT performance.
So going by that the VAST majority of PC gamers and console gamers today have a WORSE performing dGPU than my RTX3060TI when it comes to RT performance.
My RTX3060TI RT performance is much better than my mates RX6600XT,but still I need to use DLSS to get playable performance with reflections on in Cyberpunk 2077. This means in another year or so I expect,if I really want to keep using RT on in any reasonable way,I will have to buy an RTX4060TI.
It's frankly struggling today in native RT performance. RDNA2 and Turing owners struggle even more,but at this point its like comparing a Lada and a Trabant. One is technically much better,but not for much longer IMHO!
But many here upgrade every generation,so its going to be a moot discussion isn't it?!
Plus the number of gaming systems with non-RT capable dGPUs still swamps those with RT. The reality is the dGPU issues have meant many have just stayed with older designs. Its not normal for a 6 year old dGPU such as the GTX1060 to be number one.
