Valve are asking for help testing "ACO", a new Mesa shader compiler for AMD graphics

Quoting: MohandevirHad an MSI RX580 Armor 8gb for 6 months before it died on me. It was a heat generator and noisy as hell, but performances were awesome. I put the failure on MSI's bad design choices though.

Next build (around christmas), if AMD as something to offer comparable to the GTX 1660ti (performance, price and TDP), I might give another chance to AMD in another brand (Gigabyte or Sapphire).

Isn't MSI's Armor series one of the cheaper models though? Noise and heat isn't a problem with this GPU, it's a problem with that particular card. Go for something a bit more premium next time and you will be happier. Sapphire is usually a safe bet if you want a good AMD-based graphics card.

Sorry for off topic. ACO sure came as a surprise. Sounds promising. It's been well known for some time that LLVM isn't optimal for graphics shader compilation.

This seems cool, and once again Valve is doing things the classy way: Open source, working with the community, respectful tone.

I've had my Sapphire factory OC'd RX480 for several years now. Sure it puts out quite a lot of heat and can get little bit noisy under constant load but its been good card to own, well built and it still delivers (I can play most of the titles I own/play in 1440p and get ~60fps in reasonable detail). Drivers have been solid in recent years and overall I've been very happy with my investment and can highly recommend Sapphire cards.

Sapphire RX480 was indeed a bit on the noisy side. They revised and improved their design quite a bit for the RX580 so despite it being basically the same GPU it was much less noisy. A lot of people were a bit let down when the RX480 came out after Sapphire completely blew their competition away with their R9 290, R9 390 and Fury but those came with a much beefier three fan heatsink similar to what you see on their Vega. These were 260-300W TDP GPU's but Sapphires awesome boards and heatsinks managed it without fuzz and their noise levels were on par with the best Nvidia based cards. I guess it was a bit overkill for the Polaris so they developed a cheaper heatsink when the RX480 came out and the first iteration was a bit noisy with fans regularly hitting >2000rpm. My Fury usually sits at 0rpm even during light gaming, and when fully loaded (260W) it hits about 1100-1200rpm, I had two of them for a while and that was a bit toastier so then they could hit 2000rpm sometimes when putting load on both cards which could be a bit too noisy for my taste.

I am afraid that I have a very very hard time with giving AMD another chance after the "hardware malfunction error" on my Mobility Radeon X1800. Even though that was on Windows. Even though that was 10 years ago.

Thanks! You just comfirmed what I suspected. Sapphire will probably be my next try, if AMD delivers something in my price range (sub 400$ CAN).

Thing is, when you buy a GPU, you don't buy it thinking it will break in the next 6 months. This one had really cheap fans that had bearing noise problems. None of my GTX650 (ASUS), GTX750 ti (Gigabyte) and GTX960 (Gigabyte) had these problems and I never paid for premium models. There's a minimum quality that must be respected. Not going to buy any GPU from MSI ever again.

Don't let this ancient experience discourage you. I have had my share of pain with AMD as well, but that is in the past. AMD is a solid choice nowadays.

Just run a small test for TW3. aco produces around +3 fps, that's approximately +3.6% improvement in my case. That is something.

I've had access to this for several months now and it really is promising. Most of my games do see small improvements, enough to match native D3D11 performance in some cases.

And then there's Nier: Automata, which sees a massive improvement (1440p rendering resolution, RX 480): https://imgur.com/a/DBpo43T

Well, one of my brothers had three different GTX970's, some from MSI and some from Gigabyte. They're good GPU's but one of them were semi passive and one of it's fans had trouble spinning up so the card would run really hot due to only one fan spinning. Another (or was it the same?) died after a MOSFET burned up. Yes it was overclocked, but they're supposed to be able to handle that and there are safety features built in that are supposed to stop that from happening. Stuff can happen to Nvidia-cards as well but I guess they're a bit more forgiving due to those GPU's generally using less power.
