Not a problemYeah, can you match your quote to my edit please, i realised people who aren't fanatics also wear similar headdress
It says 92 degrees C on Techpowerup's review:
AMD Radeon RX 7800 XT Review
With the Radeon RX 7800 XT, AMD is going after the GeForce RTX 4070. Our review confirms that AMD has achieved performance parity in rasterization and is pretty close in ray tracing, at a much better price point, and they are giving you 16 GB VRAM, instead of just 12 GB.
With higher average GPU temps as well.
Wonder if that's correct?
Even higher than I thought. Higher RPM on the fans as well.
My brother opted for the Hellhound, partly due to significantly lower hotspot temp.
I've seen the Merc 319s go for £500, I think they'd be a better buy...

It's more to do with the delta between the edge and hotspot temp. Less than 20c is considered fine. They don't start throttling til 110c so I can imagine that temp will be ok even in summer.

Yeah i thought that but when you add it to basket, it shows VAT is already included in the 473 price.
way things are going the whole world be at it.
get those gpu orders in before it all kicks off
If i know its gonna kick off, im 100% hoarding gpu's to last me through a nuclear winter
. Just need to figure out how to power it all when the power plants go down.It says 92 degrees C on Techpowerup's review:

Wasn't there a bad batch of these or was that the 7900xt where in a certain orientation it would overheat?
7900xtx, due to a batch of vapor chambers not being filled to the right level

Yeah 92c... that's what worries me about them, 35db is not bad at all but the hotspot temps running right at the limit like that.... i don't like it.

According to TPU this one is 85c, 61c edge temp, that's a high delta... but that's at 26 db, now when you consider that a quiet whisper from 2m away is 30 db 26 is almost imperceptible, a quiet still room is 20 db. IMO the fan curve on it is set too low.
So there is some room to turn the fans up quite a bit and it still be quiet, my card is very quiet at 32 db, its a dammed good card especially for £510, it is apparently also well made, it has a plastic shroud but overall its build is quality. Its why i can't get over the fact that a similar quality 4070 Vanilla should cost £600, some of those at around £550 are just crap, in 2024 some of those shouldn't even be a thing, they are just bad.
There aren't any actually crap cards among the 7800XT or 7700XT range...

It’s a bit late. Sorry been away for a few weeks on work. Did you get a MBA 7800xt in the end? I can say max hotspot even when overclocked to 2900mhz core and 2600mhz vram and undervolted to 1040mv is around 81C tops. The fans are a tiny bit loud on load but honestly in my case I have 10 fans so I struggle to hear the card tbh. I really love the MBA looks and tried the Merc and didn’t like the looks or the fact the IO bracket wasn’t screwed into the cooling shroud so was supported only by the display ports so potentially a point of weakness.

Is clock scaling linked to the hotspot or average temp? I wouldn't let that trouble you IMO. My 6800 XT's had a hotspot in the low/mid 90's since I bought it 3 years ago yet it's never throttled as a result. When OCing without an undercoat it hit around 100°c and still didn't blink.

Starts to throttle the clocks at 110c+ (hotspot).

I wouldn’t call it useless, just a bit slower that’s all.

Yes, but in terms of clocks prior to that, I'm not sure which it's linked to. Guessing average, or does it not work like that?

Afaik it goes completely off hotspot, which is why it's so important.
