The amount of CUs was less because the APU had 32MB of ESRAM that took a huge amount of mm^2. The point is after the bad June E3 showing Microsoft's Andrew Goossen (Now architect on XSX APU) and Nick Baker sat down with DF 3 months later and gave a very detailed breakdown of why actual games on Xbox One would be equal/better than PS4 due to increased clocks. A lot of sound logic seemingly abandoned.
well, andrew goosen was sincere when he said that with xbone they didn't try to build a powerhouse, but rather a "balanced" machine. somewhere on youtube there must be the video where he speaks about it.
that was again damage control of course, but it was kind of sincere because they admitted the obvious, that xbone was not powerful enough for its time and its expected duration (both xbone and ps4 had equivalent of mid tier- gpus of their time and weak-ass cpus. ps4 in a slightly lesser degree but also was 100% saved and championed the even less powerful xbone).
then, I have to remind you that ms's plan was so STUPID that on top they also had reserved a full 10% of these limited resources for kinect.
again, in my opinion a tremendously STUPID plan from microsoft, probably because they saw nintendo selling a toaster with a remote and gathering the billions and got envious. they paid the price.
I have some questions about PS5's variable clocks and how it may affect the I/O block elements.
At what clock speed(s) do the various I/O blocks run at? All the same clock as each other or independently different? Do they run at the CPU or GPU clock rate?
Anyone have any insight?
Yes. think of it more like a seewaw, where for one (gpu-cpu) to have full mhz the other cuts frequency, and the opposite.
I have written about this, carefully analyzing what cerny said, but of course what he didnt say is how much lower each clock runs in order for the other to run at full speed. just some vague example that to cut x% consumption you only need a much less y% downclocking.
but of course the higher the clock, the higher the consumption and the thermals, thats why a stripdown and a hands-on is needed.
