£600...for a '70 class GPU, Madness, utter madness.
And when your card requires an anti sag bracket it should tell you immediately that there is something fundamentally wrong with the design.
Is it not too difficult to ask you to include the benchmarks for the 1080 Ti?
You know that gut feeling that tells you the 2030 will be £200, don't you? You try to dismiss it but it never goes completely away.
There's a partner 1080 Ti in all the charts.
My bad, think I'm going blind.... mother did warn me about that
I find both the price and performance of these RTX cards singularly disappointing, largely because of my use-case, I know, but still.
I've wondered for some time why the oldschool supports from the AT days haven't returned. Give cards an official max length, put support slots in every case at that distance, problem solved.
You can't trust AIBs card to actually meet specifications. The Reference/FE cards did (until the most recent, that goes a bit overheight) but those are actually well built enough not to need a support in the first place making it moot.
Or use intelligence when designing a cooler rather than strapping a 1KG+ block to it and calling it a day...
Also a good idea.
Edit: but really, that's a bit of a rock/hard place issue. You can't cool a modern graphics adapter with the kind of weight that an unsupported piece of PCB plugged into a card edge connector is meant to bear, any more than you can power one through that dinky card edge connector. There's better and worse approaches to the issue, but ultimately we need a whole new paradigm for graphics installation. I'd love to see nVidia's mezzanine connector become a standard graphics interface. It won't happen, but it'd be nic .
True, but the vapour chamber tech that Sapphire demoed to great effect on the 3870 Atomic seems to have died a death... and that allowed a fairly hot running dual-slot card to get compressed down into what is a fairly meagre single-slot cooler... and still be cooler than the stock heatsink! I had one, which I got when Play.com were having a blowout sale. I actually thought the fan was broken when I first set it up, because I'd got used to "turn on the PC, immediately cover ears from turbine noise". Was hilarious that it came in a (poor quality) pseudo-flight case, with "Atomic" plastered all over it. Not something you want to travel with now, I fear.
Now, I know it won't magically solve the fact that modern GPUs throw out a lot more heat... but I don't remember seeing any more recent cards really using vapour chambers. Have I simply not been paying attention? Or have patents/royalties stopped it? Or are they not good enough for these modern 250W+ TDP cards?
That's a good question.
My best guess is that it is one of aesthetics and marketing. Plain ol' heatpipes let you put those big honkin' fans all down the length of the card, and that implies better cooling to the purchaser, even if it isn't actually true. I gather that vapor chamber coolers work best with blower fans, which don't look that impressive and have a reputation for being rather noisy.
I wouldn't be surprised if the vapor chamber cards just didn't sell as well as something with a larger and cheaper cooler, regardless of actual performance.
I'm not saying they can't do better than they are doing. I'm sure they can. I'm just saying that there's a lower boundary to what can be done, and doing better is just slapping band-aids on the problem.
Vapour chambers are in relatively common use (every Nvidia reference/FE card since the NVTTM-type cooler debuted back with the OG Titan). The difference is that the 3870 Atomic had what, 150W to deal with? And with a tiny screaming fan that would not pass muster today. The GTX 1070 Katana would be a modern equivalent (similar power, single slot, teeny weeny fan).
Heatpipes are used in preference to monolithic vapour chambers on AIB cards due to cost (MUCH cheaper to bend a few generic heatpipes to the desired shape than manufacture a bespoke vapour chamber and charge it with working fluid) and performance parity except at extremely high power dissipations (high power, or smaller heatsink volume). As consumers seem perfectly happy to buy triple-slot overheight plastic-encrusted glowing monstrosities there is little market pressure on AIBs to actually build smaller more efficient coolers.
