“I don’t think there’s any argument that this is a worse console, at least for thermals and for cooling,” says Evans. Worst quote they coulda pulled. Literally sends the opposite message than the one its meant to convey. Unless im even worse at english than i thought.

Don’t think of “argument” meaning a statement in support of something. Think of it as a synonym for “debate”.

“There’s no debate” as in “it’s so obvious, there’s no one on the other side debating that it is not true”

> with rear exhaust temperatures around 3 to 5 degrees higher Is that C or F? I'm going to assume Fahrenheit. Also, is that bad? In other words, did they measure the rest of the unit to see if it was hotter or cooler? Maybe they've directed more heat to the exhaust. Which is the whole point, after all.

It's centigrade. The video does all measurements in metric (weight in grams too). Anyway it's pretty common for consumer electronics people to talk in centigrade.

My PS5 already overheats if I play a PS5 game on it with my cabinet door closed. It was never an issue with my PS4 Slim, PS3, or XBox 360. All in all I think it's the worst designed console I've ever had. The curvy top makes controllers slide off while they're charging so I had to put a drawer liner on top. The white plastic overhang seems delicate, I have no idea how I'd ever pack the thing up without breaking it. A…

Presumably a 5nm 'slim' version is just 1-2 years away, the PS4 'Slim' was released in 2016 on 16nm, which is the same timeframe as 16nm GPUs were released.

Yeah, this generation of consoles are much more power hungry than their predecessors (you can just see that in their designs). PS5 draws like ~220W from the wall, Series X draws like 200+. The 360 draws like ~120W.

The ps5 isn’t the only console that does not like to be enclosed in a cabinet with adequate airflow

Nope, like I said, it's the only console, PC, or 7.1 receiver that doesn't like to be enclosed in this particular cabinet in the 10 years I've had it.

It's not enclosed, the back is open and separated from the wall by about 5 inches.

Which is why it's all the more alarming that they've made the cooling system in the PS5 even worse.

It's C. In terms of if it's bad? shrug . With a smaller heat sink, the chips are almost certainly going to be hotter (dunno how much.. at least 3-5 degrees, maybe up to 10?). Does that matter? Tech youtubers love to emphasize cooling - which is fair, I think it's important, but I also think it's overdone. From the end-user standpoint, the question is does this meaningfully increase the rate that their unit thermal th…

I think for the end user the primary concern is not performance, but the potential fan noise.

If the performance goes up or down, end users might not even notice, but if the fan is constantly kicking in and being too loud too often, more people will be concerned.

The 360 also has a 32th of the memory and a 50th of the graphical performance. If you prioritize power draw over performance you can always continue using the old consoles.

Consoles have design lifetimes, and thermals are part of the computation that helps you figure out if your components are going to last as long as the warranty. Obviously, if you run a chip hot, its service life will be reduced.

So companies develop models that tell them how long things like the SOC (main chip with CPU, etc.) will last for a given temperature and use frequency, and whether or not they've got a 1-year design on their hands, or one that will last 20 years.

The model improves as you gain experience with manufacturing, customer issues, and get more testing than you could do before launch. Making the systems too beefy can be expensive, and saving pennies really matters when you're making millions of units.

So I imagine that the folks at Sony determined they could get away with a smaller heatsink and still have an acceptable fleet failure rate, probably a year or two out from the posted warranty.

Does the power usage scale with resolution? Do games have "run at 1080p vs 4K but cooler/less power" option?
