Is data throughput an entirely separate processor? I just assumed that running eye controlled AF and perhaps improved AF (happening faster - less time between frames, so even quicker processing required), plus the higher demand on power consumption (driving lens AF and aperture), as well as added heat reducing efficiency, all played a role in the 45x20=30x30 not quite adding up...

Doesn’t 45x20=30x30 assume that every single other detail is the same? Surely, with all the improvements Canon has added to the R3, it’s got to be doing a bit more behind the scenes, no?
The 1D X has two Digic 5+ processors for the imaging pipeline, and a Digic 4 to handle the AE algorithms. No reason the R3 would have to have only one.

No, I haven’t. I was responding to the the claim that 24 MP was a technological limit, and it’s not.
It may be, depending on how confident they are with their sensor production. As it is their first stacked and BSI sensor, we don't have a reference for how well behaved that is, do we?

Of course, that would be more of an economical limit caused by technological challenges, as even if for example their yield was quite low, that could be compensated for by a higher price.

We have to work with what technology provides us with at any given time. I trust Canon is doing the best it can. For a 'speed demon' camera they are launching in R3, 24 mpx seems to be the best compromise between speed and mpx. With time, engines will take more torque and the mpx will increase.
I do not believe the 24mp is a compromise. I think the 24mp is a deliberate choice because Canon believe that is the intended markets preference. Just like Sony and the 12mp A7S , A7S II, and A7S III.

I know a few professional wedding photographers that are more video orientated and use the A7S for the still photography as well when doing both at a venue. In fact it’s a remarkably popular camera for this.
I would use it if i am hired for both video and photos and I know the only place the photos will end up on is social media. I wonder how the noise looks on a low mp camera at a high iso compared to something like an r5

As AlanF has mentioned many times to do a proper noise comparison you will have to downscale R5 photos to 24mpixel.

That makes sense because of course, as we all know, a 12 MP image is entirely unsuitable for printing, enlargement, or any other use than a 0.8 MP instagram upload.

Side note, that image sure is blurry! Probably because it was shot on a 12 MP camera.

They could also use dual Digic processors if needed (or more, the 1D X has three of them), if needed. As I said, 24 MP is a choice.
Agreed.
I think Canon mentioned 'a' Digic X processor in the R3, so I'm assuming one?

A two year cycle is around average for new Canon processors at the moment, no doubt we'll see a Digic 11 (XI) in the R1 next year, even multi XI processors.

I'd assume just one, but I do recall that Canon highlighted the 1D X as having 'dual-digit 5+' in the development announcement, and didn't really mention the extra Digic 4 that was in there for handling AE.

I do prefer high mpx than low, and would be happy if Canon one day comes out with a 'speed' camera with higher mpx.

Honest question: is the 20 fps of the R5 not speedy enough for you? Or do you mean a higher MP body with integrated grip (something I prefer strongly, an add-on grip just isn't the same ergonomically)?

I briefly flirted with the idea of a A7S for low light work during church wedding ceremonies. That was until I compared my 5DS cameras with the A7S at my highest required ISO setting - 6400 with the 50mp 5DS downsampled to 12mp. Although the A7S was a little better the difference wasn’t worth bothering with.

Beside the point a little maybe, but wasn't DIGIC X a cover term for a range of processors? When they first came out, I thought Canon said different iterations could be called that, so it's not like in the past where, eg DIGIC 4 had a given capacity, which was subsequently exceeded by DIGIC 5. I'm not even sure XI comes after X, any more than the 1Dx was followed by 1Dxi.

Yeah, it will be interesting what they'll go for once they want to push the notion that the processing is a truly new generation. But for now, DIGIC X is just a marketing term that covers different chips.

Ok. Possible. Maybe.
Well just use logic, Canon already sell cameras with processors capable of processing much more than 24mp at 30fps, they also already sell sensors with a lot more than 24mp, ergo the choice of 24mp is entirely a choice.

After considering those facts you either think Canon arbitrarily decided to go with 24mp, or they did market research with the intended market for the camera and those potential customers said (in the region of) 24mp.

I did not mean just fps. The overall speed of the camera and performance.

But these cameras are not as 'fast' as R3. Logically speaking ie.
