I got a 4070Ti paired with a 3600 at 3440x1440 and it is glorious. The 0.1% and 1% lows are barely noticeable for me, probably because adaptive sync does such a good job at hiding them.

orange juche posted:FSR3 does run on RDNA2, since it's an open standard and AMD specifically stated it would run on older hardware, they'd be silly to not have it run on older hardware as current consoles are RDNA2 based, and also the lions share of their graphics hardware goes into consoles. I have been reading a bit on rdna3, and was pleased to discover it has acceleration for matrix operations, though this doesn't seem implemented through specialized circuitry. I bring this up because it seems like FSR3 would be perhaps be much more competitive if it utilized what rdna3 has baked in. If their goal is to sell rx7000 gpus, being an rdna3 exclusive--particularly if it rivals dlss3--doesn't seem like such a bad idea. Edit: rdna3 got the ability to handle dual issue fp32, so never mind: what can run on rdna 3 should work too on older rdna architectures, just more slowly.

Both the GPD Win Max 2 and the Beelink PCs use Zen 4 CPUs (the 7840U and 7840HS respectively). I think the 7840's memory controller is better than the desktop Ryzen parts due to something to do with the monolithic design, and maybe the only reason why the Beelink uses slower memory is because it relies on sodimms (which don't come in speeds that high), while high-speed LPDDR5X can be soldered onto the mainboard close to the APU. Zen 5 will almost certainly have a better memory controller than Zen 4 though. I'll be disappointed if it won't be able to utilize memory speeds of 7000 or more (which Raptor Lake already supports).

power crystals posted:The 5800X3D is notoriously a nightmare to cool due to the stacked die topology (the cache die effectively acts as a thermal insulator). The stock cooler won't break it or anything, but getting a fancier one may appreciably improve its performance by letting it boost for longer. One of the best things you can do with the 5800x3d is undervolt it a bit on vcore, I dropped my voltage down in the BIOS by nearly 0.1 volt, i think .08 or something, and it shaved off 10C as long as I'm not under all-core 100% utilization. The CPU doesn't get nearly as hot under gaming loads as it did before, I was sitting close to 80C while playing VRChat, and went down to 68C with no other changes. The amount of thermal load that the stacked cache puts the CPU under is pretty crazy, the CPU itself won't use more than about 70w under load, but it will drive right on up to 80C even under water cooling because the cache die blocks heat from traveling from the cores to the IHS. orange juche fucked around with this message at 00:34 on May 7, 2023 |

Two issues I've had with my 6600 was high memory clock and idle power usage when in multi screen and a black screen of death with chrome video playback which made me finally move back to Firefox. Drivers have been fine for gaming and it really is the only option in the price range but it is pretty obvious it is not going to have anything like the longevity the 1060 it replaced had.

It's 2-3 times as much stuff to glue together as a Ryzen CPU, so that number kinda makes sense on a napkin. Very funny that AMD keep it in the driver patchnotes as a known issue to placate the fans, as if it was fixable.

10x as high is way off but "proper" idle power for RDNA3 is seemingly about 5W per MCD, before driver patches it was 71W/81W for 4MCD/6MCD configurations and after patches it was 46W/54W. Given the relative changes between the two products, it sounds like the problem was primarily that the GCD was not idling down properly, moreso than it was blasting the MCDs improperly. So presumably in the absence of MCDs, it would idle at something like 26-28W for the GCD alone which is not dissimilar to the measured 34W idle for 6900XT (which has "MCDs built in" of course, in the form of PHYs on a monolithic die, but it can idle them better because it's monolithic). So yeah MCD does ramp up power by ~30-40W but not 100W. The problem is, of course, that you have that power anytime you want to talk to memory or maintain state in cache/etc, even if the GCD is essentially idle it still needs memory to talk to... sort of like how adding a small iGPU (or a small cache) on the IO die is a good idea for power efficiency compared to having a full chiplet. The evolution of chiplets is all about how you break apart the components so you can control when the chiplet has to be powered on. Incidentally when you look back on that talk from the radeon engineers about how the power penalty of MCD was pretty minimal (supposedly only 15W)... that really must have been idle power they were talking about.

I set both monitors to 60hz and now have an idle power usage of 18w-30w. I have never encountered this with a 1080, 970, or 7970. One monitor is 144hz, the other 60hz. The 60hz panel sucks and I was going to replace it anyway. Will two 144hz monitors be a problem, or is it only as you said: two monitors of different refresh rates? Thanks for your help, everyone.

It's not differing refresh rates that does it, really. I have two 165 Hz monitors. When both are at 165 Hz, my 4090 pulls around 100 watts at idle. When the secondary monitor is at 60 Hz, my GPU idles at a more reasonable 30 watts. I can set both to 120 Hz, and it's more like an 80-watt idle now. Just having one of the monitors at 60hz is enough to let the memory controller run at a lower power state. edit: Despite the above success, I highly doubt it's the mismatched refresh rates that does it exactly. GPU memory controllers just don't like high refresh displays and are really fickle in general. It seems unlikely to me that a second 144 Hz panel will solve the issue. But there can be strange quirks to the way monitor timings and pixel clocks work on different monitors, and some monitors randomly seem to be less disruptive to a gpu's idle states than others.

Just having one of the monitors at 60hz is enough to let the memory controller run at a lower power state. You are likely correct, but my dinosaur of a 60hz panel is not long for this world anyway. From my experimentation, refresh rate does not impact idle power with one monitor alone. With two monitors, it seems to scale with the combined refresh rate: 144hz + 60hz uses more idle power than 120hz + 60hz and so on. This seems like a problem on the part of AMD as my 1080 and 970 never did this. I do appreciate having a stop gap solution (running 60hz+60hz day to day), and I can only hope that this can be fixed in software.

AMD would probably prefer it to be broken into multiple smaller shaders with manual sorting steps inbetween, but then it wouldn't be able to take advantage of nvidia and intels on-chip sorting. the only way to make everyone happy would be to implement both approaches i think.

Been tinkering with undervolt settings for my 7900xt and my best scores on time spy extreme are a few hundred points below average. I’m wondering if it’s below average because the average 3Dmark user is overclocking/enthusiast grinding for performance/score or if I’m genuinely behind the majority of people who have a 5800x3D/7900xt setup?

In my experience, 3DMark averages tend to be slightly below what is normal for a typical, well-built PC because there are always a bunch of people with a dozen kinds of malware running in the background using these benchmarks too. That said, I wouldn't sweat a difference of just a few hundred points. That seems roughly within the margins of silicon lottery, and it shouldn't lead to a noticeable difference in gaming performance.

wolrah posted:This behavior is not fully understood and sometimes can come and go with different driver releases, so it's hard to say anything for sure. As alluded to by other posters in this thread, the memory clock is fucky. I recall this being a problem with some 3090tis. At 144hz+60hz the memory clock is locked at 2487mhz, at 120hz+60 it is locked at 909mhz, and at 60hz+60hz it varies between 25-110mhz. Given that, I am reluctant to place my hopes in a new monitor fixing this issue. Replacing a 9 year old 60hz panel isn't an unappealing idea, but my 144hz monitor is no longer available at a reasonable price. That is to say, an identical match is impossible, though getting the exact same settings on a newer LG 144hz+ panel shouldn't be a problem. As it stands, 120hz+60hz is an okay compromise with idle power usage at around 40-50w.
