Thanks to CPU boost. GPU probably isn't (or not fully). AC Unity shows this very well. In areas where the PS4 game was CPU limited, the game is locked to 60fps on PS5. But the game has big framerate drops during GPU heavy (well heavy for PS4 at 900p) moments.breakpoint and division 2 got upped to 60fps on PS5.
Gotta say, the shrinking of the heat sink poses far less of a concern than that of coil whine. The power supply coil whine on some units completely cancels any effort spent on acoustic design. I wonder if the new model has fixed this.From the PS5 new 1100 model hands-on from Digital Foundry we learn interesting power consumption measures.
- Control regular gameplay (30fps RT mode): 170W
- Most demanding scene (corridor of death, 30fps RT mode), but still gameplay: 200W
- Photo mode unlocked (non gameplay, taxes mainly the GPU according to a reliable source who has actually profiled the game during photo-mode): 214W.
So what does it tell us if we trust Cerny and the dynamic clock system that is based on instructions load which are themselves based on actual power draw? It means the PS5 should run at max clocks in the vast majority of time as it seems the actual max power consumption (so logically the max number of instructions before a downclock) could be higher than 210W (and not 200W like previously thought).
During normal and demanding gameplay the system should run at max CPU / GPU clocks and it could lower the clocks only in very specific conditions: photo modes which are similar as cutscenes / when game is put in the background. All those scenes share the fact that the GPU is not limited by any CPU logic and is stupidly (and uselessly) trying to work as much as it can. It can also happens in plenty of games when you enter the dashboard while a game is running in the background. Also in some games menu and maps.

On my unit the coil whine is the loudest while playing Genshin Impact, which is curious, as we thought Astro’s showed the upper limit of PS5’s power draw, apparently Genshin draws more?
Oh that could be why.On pc, coil whine doesn't go linear with power. It have a sweet spot where the whine is the loudest. I assume ps5 is the same.
If you had heard a coil-whining PS5 coil whining under Genshin Impact you would not say that. On my unit the whining penetrates through the game audio and the sound of my fridge in the other room, it’s not higher pitched than what I’ve previously heard while playing Astro’s or SM:MM - it’s hard to describe but definitely more noticeable. This is a bit of a concern: with more game to be released, who knows how much worse the coil whine can get?Unfortunately most human are unable to hear coil whine…
Btw does all PS4 games now automatically got boosted to PS5 (like Xbox Series). Or it's still only boosted to ps4 pro?
wow, that's way better if those CPU temperatures are accurate. Significantly better. Surprising really, wasn't expecting the resistance level to be better while being smaller.
Good video. Numbers start at 5:20.
Due to the VRMs and DRAM (edit: NAND) also having lower temps and not just the SoC I think we can eliminate hardwarebusters getting lucky with the silicon lottery. This heatsink redesign is simply superior despite the lower weight.I appreciate that the presenter noted the minimal sample size and his luck in both units having the same fan model.
My only reservation is that they didn’t really show how they measured soc temps. So I have no actual idea how accurate it is. It’s promising, of course, but this is the first time anyone (?) has provided soc temps, so they should have spent more time explaining how they rigged that up.Due to the VRMs and DRAM (edit: NAND) also having lower temps and not just the SoC I think we can eliminate hardwarebusters getting lucky with the silicon lottery.

He says in a comment that he measured the SOC temp from the back of the board, so it isn't so much an accurate reading of the SOC, but the PCB below it. But if he measured both systems in the same way, it should be a fair comparison. I'd like to see more also, though.My only reservation is that they didn’t really show how they measured soc temps.

So does this mean that Sony actually made an improvement?
