I know the latter cards may generate more heat, and thus have "thicker" heat sinks built into them for that reason, but surely they could have been redesigned more efficiently, so that they still only used the two slots? Just pointing that out as an observation.
yes that would have been doable as its the complete opposite to what amd and their AIBs have done.
AMD had designed the 7900XT/X series with compactnes in mind as the reference cards came in smaller packages with needing only 2 8-pins connected to them.
but AIBs like Asus for example with the TUF series went and made the card 2.3 slots or something with a 3-8pin power supply.
this made the cards some monster cards with slot requirements.

Nice to see the 4090 TUF OC I bought at launch from PCCG for $3459 is now $2769. Hopefully the price comes down even more for those wanting to grab one of these bad boys. Not only is it a fast card but also ironically the most efficient card I’ve ever used.

I read coil whine was an issue for this card, can you comment on that?

I just bought that model from Umart the other day at that price. Oddly enough the non-oc version is still a hundred bucks more.

From my brief usage, I'd call mine more of a low coil buzz than a whine. I still have my side panels off and I can hear it from ~40cms away with game volume off. It's barely noticeable and you have to listen for it. It's certainly not obnoxious.

Never had any issues with mine. But I undervolt all my GPU’s so maybe could help for you.

What are your undervolt settings, and how is performance compared to stock?

See, that term I don't quite get. You buy a card with supposedly standard specifications, yet you still under volt it? I know what undervolting does in the general terms/field in regards to GPU technology _when_ overclocking, , but seriously, Nain, or someone else, could you elaborate what this actually achieves in the current climate please?

By reducing voltage below the conservative levels set by default (designed to ensure stability with even the worst silicon that still meets the specs), you can get lower power draw and lower temperatures, which in turn may let the card boost higher for longer.
Increasing power efficiently like this could also increase the lifetime of the components.
Der8auer did videos around the time of the 40 series launch, and from memory reducing power consumption by a large chunk (25% or more) had a negligible impact on performance.

^ Ada GPUs are quite efficient when undervolted, even the 4090. The cards are pushed very far from optimal point on the efficiency curve. For example at stock settings Metro Exodus might be roughly 112 FPS at 445W but when undervolted to 2535 MHz@875mV, at the same spot you get 103 FPS at 315W.
~40% power savings for ~8% performance loss.

I would want the same performance for less power. That's the only thing that makes sense to me.
Even at 950mv I am seeing a performance loss compared to no undervolt and 80% power.
Still unsure if 40 series actually benefit from undervolt compared to power limiting.

Undervolting can allow clocks to boost higher whereas limiting power doesn't. The former gives you more power within the same budget to spread around, whereas the latter reduces the overall budget.

Maybe undervolting works better for typical gaming use. I need 100% GPU sustained for many minutes. 80% power gives higher throughput compared to undervolt of 950mv at 2700mhz 100% power. Undervolting does reduce power and heat, but also performance.
To be fair I've only ever tried 950mv and 2700mhz, there's probably a lot more to try that may result in equal or better performance to a 80% power cap

100% GPU performance is relative to what your silicon can achieve. Your silicon quality is different from everyone elses.
You can still get 100% GPU performance with an undervolt, the reason you're not is because what you've tried
I've only ever tried 950mv and 2700mhz
is too low an undervolt for your silicon to be able to maintain 100% of its factory performance.
Been a while since I have looked at 4090 prices.

Typo there. "Suss" has double S.

Pretty sure this one is legit though.

Looks like 4090 prices are falling but the 4080s are holding a bit. Was hoping they would be under $1600 by now...
the 4080s are holding a bit.
Not really much incentive for the prices to drop more at the moment if Nvidia doesn't want them to. Directly under the 4080 sits the 7900 XT. Still a lot of Ampere stock propping things up as well.

$1699 at umart. Unless AMD drop the prices of the 7900xtx there isn’t much reason to. Despite the $200 usd difference they are the same price at stores.
