This has been discussed on this thread already. A node shrink is nice, but it is not a mandatory requirement for a major performance uplift. 780 Ti -> 980 Ti proves this. Same 22nm node but 50% performance increase.
That is exactly the point...just because it's 512 bit which is exactly double of 256, why would he even bring up the possibility of MCM if 512 bit is already possible on a monolithic die? The reason why MCM was brought up, to generate buzz. Which clearly worked.
I'm no engineer so I won't comment on how hard or easy it is to do accurate EOTF tracking, but yes you are right it is possible to do if some effort is made. As others have mentioned, the launch of the 32GS95UE was probably rushed in order to get something out to market before QD OLEDs take up...
We have had 512 bit memory GPUs in the past like the R9 290X. His tweet of saying he doesn't know whether it's MCM or monolith basically got everyone jumping on the possibility that it might be not monolithic which is expected. I'm pretty sure he said it on purpose to generate some buzz because...
I do have a mini LED lol. But I also have an OLED as well because mini LED doesn't get anywhere near 240Hz OLED in terms of motion clarity. Until OLED monitors get up to at least the current TV level brightness, it won't be the death knell of anything.
Well is it brighter because the EOTF is totally screwed when running in High Mode? The GR27 is also known of be one of the dimmest OLEDs and so LG had to refresh it with the GS27 after just 1 year so being brighter than the GR27 isn't really a huge accomplishment.
I don't own the LG monitor so I won't say too much, but I highly doubt it is "a lot brighter" than a C2 in real content. Everything that has been shown about it so far has all been limited to just a bunch of test slides. Once RTings gets one in then we will know for sure whether it is a lot...
