Junction temperature is the highest temperature of a semiconductor (GPU hot spot, not entire package) on a card.

Don't confuse junction temperature with GPU temperature, two very different things and pretty much all cards will reach 100c plus on junction/VRM/hotspot, but typically a card won't sit and remain at 110c limit it will be brief or not at all in normal use, but of course if the cooler is faulty (lack of water in vapor chamber) then the card is not able to remove heat effectively or quickly enough from the GPU because vapor chamber is not working, at which point the card see's temps at 110c quickly and not reducing so throttles hard. A card with a working vapor chamber should only be reaching 110c is stressed heavily and it should still take some time. In regular gaming scenario it should not hit 110c or if it does will be short and/or a minor throttle to within spec will solve it.

Fair enough.

I can only see this been a bigger issue going forward with higher transistor density too. The 13900K/KS is a good example. Hit it with a voltage to not crash to get the 5.8Ghz/ 6GHz boost to it hits 100C and throttles. The Ryzen 7000X are crap too, need dialling in or 95C. All getting a little messy now.

Agree. And to think, people were calling my 9900k a "toaster" when I bought it! :)

pretty sure a card running at 110c hotspot is not going to last any longer than its warranty period at best

I think 110C under normal gaming conditions is definitely on the toasty side but both my 3080FE and 6950XT could hit 100C hotspot gaming and GDDR6X on the FE hit 104C!

Back in the day my 8800GT would hit 110C playing FarCry :p

Yep sorry, they have been delayed further, it seems AMD is testing them prior to shipping as the 300 units expected to ship is now reduced down to 265 units. So they are checking the coolers.

In short good and bad cards reach 110c junction temperature but a faulty card will reach if pretty damn quick, even with regular gaming and then throttle heavily below even advertised clocks.
A working card will still reach 110c but it takes longer and normally only using stress testing or benchmarking, gaming less likely and even then when they do hit this temperature the card only throttles a little and is still within AMD guidelines.

Hey Gibbo, I bought the Sapphire Radeon RX 7900 XTX with 2 yr warranty, can I change my order to the Nitro + the warranty I've already bought? Thanks

We don’t sell warranties.

A card comes with a warranty but if you contact customer service they can change / upgrade your order for you.

Thanks for the update, and I saw your post on the other thread! Would it be possible to preorder for delivery next week by chance?

I’m away for a couple of weeks from the 28th, and would love to get my GPU situation sorted beforehand! I’m happy to preorder (at the discounted price you suggested ) if it means I can get one sooner!
 
@Gibbo just wondered if you had any update on ETA for getting Powercolor Radeon RX 7900 XT Red Devil? Had one on pre-order since just before Christmas and I see most other XT cards in stock?

Aye, in my case it was CNY. So was busy all weekend. So I totally missed that deal offer. :(

Still, with the supposed refresh only 2 months away, I might wait 2 months to see if there really is a 7950 XTX and grab that to pair with my CPU. :)

There was a report a refresh or rdna3 plus has been scrapped.

Dismal AMD RDNA 3 refresh rumor suggests all RDNA 3+ RX 7000 SKUs have been canned

Launch reviews of the RX 7900 XT/XTX found that the GPUs weren’t performing as well as AMD had advertised. This disparity between the marketed and the measured performance sparked speculation that the Navi 31 GPU might be suffering from bugs. Later rumors suggested that a revised Navi 31 could...
