What's the best free stress test for GPUs?

Ignore what the table says - Valley and Heaven both run constantly anyway in a demo mode (not sure about Superposition)

I may be strong becayse I haven't installed Superposition in a long time but I'm pretty sure they changed that with it. Hence the reason I've stuck with Heaven for all these years.

Unigine Superposition although you dont exactly say what you are stress testing, an overlock? an undervolt ? a stock card but then again why do you want to stress a stock card ?

Heaven and the above would always give me a guide as to whether my OC was successful or not.

Does it matter? People stress test to test stability whether the PC is at stock, undervolted or overclocked

I'm really just looking to make sure it's not overheating and throttling at stock, and I think I'll go for Superposition and Heaven.

Thanks for the replies. :)

There's also EZBench (it's on steam)....It's not really a benchmark as it produces inconsistent results, but it'll definitely put a serious load on a GPU. (there are also some murmurings in the steam reviews speculating whether it's data harvesting to some extent, so at your own risk!)
 
Since you've said no to CP2077, another vote for Superposition.

However I've just been running some undervolt tests on my new 7800XT and settings which ran fine in Superposition would crash the CP2077 benchmark, so I'd advise testing across multiple different benchmarks/games before coming to the conclusion it's stable!
 
Depends on what you're trying to stress, if it's the thermal solution then a power virus like Furmark, Kombustor, or OCCT will do that. If it's the GPU core and/or an OC on the core then pretty much any benchmark like Time Spy will do. If it's the memory and/or memory OC then something like MemetestCL is what you'd need, although you shouldn't really need to stress test VRAM as it's EEC so any instability should really show up in benchmark results due to correcting loads of errors slowing things down.

Yeah but stable is stable regardless of use case....
What would yoy recommend to test stability for a stock s vs an overclocked vs and an undervolted system?

I already did for free you must have missed it. See also above post for same line of reasoning.

I'm now looking to test how my case and AIO copes with heat - what's the best way to stress burn the GPU and CPU at the same time?

For example, is there a GPU test I could run at the same time as Cinebench R23

I believe Furmark/Cinebench is the most common 'murder your system' load :)

Wait until a really hot day in summer (unless you have AC) and use it like you normally do but with something like HWInfo running to see how close it gets to throttling.

I know stress testing used to be a thing, and that it's a good way to check HW is running as it should, but do people still bother with extended stress tests? Back in the day I'd do it to test for stabled overclocks and set the right fan speeds but with how most modern hardware runs at maximum clocks, throttles based on temperature, and lets you set fan curves i thought extended stress testing was largely redundant these days.

I just ran a quick Cinebench test when i built my system and set the fans to be at 100% when it's 5-10°C bellow the throttle limit with a reasonable curve leading up to that.
 
A proper stress test you say? got to be Furmark that will give it a good workout lol but sensible option is use the Metro Exodus EE benchmark tool.
