The always polarizing DXOMark has released their sensor score for the Canon EOS R3, and it's the highest for any Canon camera in their database with a score of 96. While this may be Canon's highest sensor score ever, it's still behind offerings from Panasonic, Sony and Nikon, but very slightly.
DXOMark did call the Canon EOS R3 the best low light performer in their full-frame sensor database, something Canon hasn't been at the top of for quite some time.

While we’ll have to wait and see what form a possible top-of-the-range EOS R1 takes, the Canon EOS R3 is certainly a compelling contender for its intended market. Not only does it have excellent dynamic range at key low, mid and high sensitivities, it has the best low light performance of any full-frame camera in our database. This makes the Canon EOS R3 a very attractive option for Canon EOS-1DX Mark III users transitioning over to Canon’s mirrorless RF system and it’s a solid option for any photographers new to the Canon brand.

Edit: also excited to see this sensor tech in new cameras.
The R3 is surprising good and my favorite Canon camera to date. Size is perfect. Neither too large or too small.
And btw it shoots 30 fps lossless raws with best AF system(according to testers), plus animal af in video, plus big battery, and it's cheaper than 'you know who'.
But somehow 6000x4000 is a deal-breaker.

If the camera only had a clown face recognition... imagine the hit rate...
I do have both but I use them in different situations.
Actually R5 is underused until now but I have verified that it is easily (DXO) cleaned up to high iso (I have tested 10000) and it's superb for shooting at low light using IBIS + IS (I have tested mostly RF 24-70 2.8L IS)
I have shot once a low light scene with my D850 and 500PF (my only lens) I was amazed by IQ. OK, I was using tripod and low ISO but it seemed to me that I got the resolution of 5DsR with the low light IQ of 5DMkIV combined in a single camera!
I would get more Nikon lenses but I have a complete Canon system and I love Canon lenses... And now IBIS with R5 gives even more advantages...
I went from the 45MP R5 to the 12.1MP Sony A7S3 and lived to talk about it. The R3 should suffice.
The 24 megapixel aspect is, surprisingly, not much of an issue for anything that isn't reach-limited. It really does shoot above its megapixel weight. The comment from some days ago that it's about the sharpness/detail equivalent of the 5D4's 30 MP is probably exactly right. But at this point - despite loving the R3 - I don't plan on keeping it because the things I shoot typically *are* reach-limited, so the R5 is going to be better for me.
My average published shot is perhaps 35 percent of the frame, and typically winds up 300 dpi. To give perspective, with the R3, if you shot in landscape orientation something you wanted to be on the cover of a magazine, you'd be able to crop only 1/8th of the height of the image before you sank below 300 pixels per inch. And, yes, you can get good cover shots with 4 megapixels, yada yada, but if you brought a 4 megapixel sensor to this knife fight, you'd get gunned down most times by someone else. I had the same decision back when I had the A9 Mark II (24mp) and the A7r Mark IV (61MP). I found eventually that I kept using the A7r4 whenever I went to shoot wildlife, even though it was really the remit of the A9; and it was just for the resolution. Been there before. But I do recognize my use case isn't normal.
As an aside, I see a lot of people assuming the R1 will be a higher resolution sensor, but that actually doesn't conform to any Canon precedent. I expect the R1 will be a really cool camera with a sensor that will - as it has for the last decade, without fail - disappoint those wishing for resolution similar to that found in competing cameras. I'm hoping, instead, that we'll see an R5 Mark II in two years (yes, it'll be that long) that adopts much of the R3 tech and even more resolution.
For the R1 I don't think we'll see much more than 50MP max. I could see a few scenarios: 1) 50mp-ish stacked sensor to double the R3 2) 36-38MP sensor which is just enough to give 8k video and far enough away from the R3 to make sense or 3) The same or similar resolution to R3 but with additional features.
With the R3 at 24 and already blazingly fast, I doubt we'll see a resolution there or lower. Even with QPAF and global shutter, I don't know if that would be enough differentiation. Especially since I think they want to price this thing at $8-10k USD. (I'm hoping the competitive pressure prevents them from doing that anyway, but Canon doesn't seem to care usually). So I don't know how likely option 3 is.
All just guesses, but I do enjoy the speculation.

If you want 8192 on the long side, the number jumps to 44.7MP.
I think it’s save to assume the R1 will need to be 40MP+ to compete with the very excellent Z9 and A1.
Canon already had a 45MP sensor. They will most likely take the R5 sensor stack it, BSI, and perhaps something else to improve performance and throw it into a R1 body.
I’m more curious about Canons upcoming video sensors and their supposed DR claims. I would love a C70 FF camera with a DGO sensor and 14-15 stops dynamic range.
