No, it's actually the other way around. PS5 silicon was designed keeping in mind it also has to play nice with PS4 silicon. Cerny (more or less casually) mentions this in his talk. AMD (and probably Sony watching over it) had to make sure that the "new transistors" don't run havoc when they see microcode intended for old PS4 hardware. This is a bit difficult to explain as it actually constitutes a huge engineering problem. (What AMD really did I have no clues at all). As the naive solution, the PS5 could just kill half its CUs and lower the clocks to 800MHz on the gpu side and lower the cpu clocks to maybe 6-700MHz which makes it look like the new PS5 SoC executes with the same speed as the old PS4 SoC. This will not work in many cases as the timings in the new SoC would/could be completely different. If the PS5 runs too fast, all hell could break loose because the old PS4 code was not meant to run that fast (particularly code which used gpu cycles for async compute stuff on the PS4). In that context, the "dumbest PS4 game" is probably the safest bet for full bc, because it doesn't do tricks. My guess is it's the 1% of "tricky games" that constitute 99% of all headaches. Apparently within the 100 most popular games tested, the chosen solution seems to work for almost all of them out of the box. |
Cerny was explicit that they baked some of the logic of PS4 inside the silicon of PS5 and that is why the BC can't be removed.
The 100 tested is still unsure if they tested regular or boosted. We will need to wait for more info.

I haven't seen anyone on VGC bragging, the stats are what they are. The definition of 'pushing the boundaries' has to at least consider what the boundaries are. Given the Series X is clearly significantly more powerful, the PS5 cannot be considered the boundary. You can be damn sure Cerny would have had a different focus if last week Microsoft had announced lower CPU or GPU specs, or hadn't had vapour cooling. |
And what are the boundaries? Because I put where the PS5 pushed farther than Xbox, but you won't acknowledge them for whatever reason.
Also you may deny if you want but you know there will be a lot of bragging until the end of the year and then an exodus.

Not really a problem. MS just revealed XB early and yet the PS5 logo generated more buzz. NX was talked about forever but not revealed til October 2016 and we still knew almost nothing. 3 months before launch is when they gave us solid info. 52 million systems later... . Once Sony shows a box and price it will generate more buzz than Xbox unless Sony pulls an Xbox One with odd restrictions that piss everyone off. |
Pretty much this, not sure why some are so anxious to early.
