NVIDIA RTX 50 SERIES - Technical/General Discussion

I thought the issue was that it isn't enough of an uplift over the 4080 (Super). I imagine if you upgraded to a 4080 card you'd be happy with a similar "huge upgrade" over the 3070.

There are many benchmarks which show very little uplift from 4080 super to 5080 and they are shown extensively in the reviews. There are some games that seem to perform badly on the 5080, and you can either believe there is some design flaw with the 5080 and that's why it performs the same as a 4070 in those tests or you can believe that it's a driver/engine issue and that it will improve (hence my fine wine comment). Then there are benchmarks were the 5080 beats the 4080 super by quite a margin and these just happen to be games and benchmarks that use newer technologies.

My comment was more that I am happy with what I am seeing so far with the 5080 even compared to what I know about the 4080 performance, and I believe the performance difference will increase over time.

Is there any chance it could be my power supply being insufficient? NVIDIA recommends a minimum of an 850w PSU, which I have, but I'm also rocking a 9800X3D, two SATA drives, two NVMes and a sound card (yes, in 2025.) Slightly ignorant on the power supply side of things, but fortunately I'm not afraid to show my ignorance.

I would have thought you’d only encounter issues when you're thrashing your GPU. And if the pcie 4 solution works for you, you can probably rule that out.

You can have a quick tot up of the expected power usage on some PSU websites to get an idea of what you’re actually drawing. Or have a look using HW monitor or similar.

I wouldnt imagine so unless there was a fault with it. What GPU were you running before the 5080? You could always do a OCCT PSU test to check stability.
There is little to no difference running it in X4 to X5 and it is being reported on reddit about this issue so i dont think you are an isolated case.

Tbh I don’t think I’ve ever encountered a power issue where the outcome wasn’t “system shut off” and not something in between.

Suppose the easiest way to test is run cinebench on a loop plus a GPU stress test and get them both chugging power - if your system doesn’t shut down and you can see the power draw near their specced TDP/TGP/whatever then you know the PSU can supply them both fine.
 
Did you try running in High performance power profile or using process lasso Bitsum highest performance profile just to check it's not the CPU or some power saving tech causing it?

Indeed yeah, I suppose I'm just a bit paranoid because reports of the third-party cards doing it are really sparse at the moment. I think I've seen four different people, and that is it. I had a 3060Ti prior as I was hanging on for the 5000 series before I replaced.

Nor me, but I guess I reasoned that it would only be pulling 'maximum juice' when under load. I did run 3DMark which was heavily on the utilisation, had no issues then. I'll give Cinebench a go, and perhaps also the 3DMark stress test option.

I'll give it a try.

5090 runs Kingdom Come 2 at 8k Ultra 30-40fps. Pretty impressive. Enable dlss quality for 60fps and performance for 100fps. 5090 can also do 16k with dlss performance for 45fps

After spending almost a week with the 5080, the card is nowhere near as bad as the reviews are making out, and a huge upgrade over the 3070. Performance in some tests like Steel Nomad has it at 30% faster than the 4080 super so perhaps a sign of things to come. I think this could be a Nvidia fine wine situation.

Agreed. My FE 5080 is running brilliant, great upgrade even from my 3080. The reviews have crapped on it unfairly tbh.

I'm also achieving +2000 Mem and +450 Core without any issue or artifacting, done a few hours of stress testing and temps are great, not exceeded 72c.

For day to day I have clocked it down to +1000 Mem and +300 Core just to be safe however.

Reviews are always comparing new cards to previous card. If you owned a 4080 then you'd think the reviews are accurate because the performance gain is tiny and the price is high. Of course if you go from a several generations old crd to a new one it's going to look good for you, that's the same with any electronics whether it's TVs, phones etc you wait several generations and then upgrade for a big jump but reviews aren't comparing the old stuff they always look at just the previous gen and try to find additional value

Even then the value is a bit iffy even if the performance feels good. 3080 was 649, average price of entry AIB 5080's is currently around 1200. So 5080 is 68% faster than 3080 but presently costs 84% more. Once prices come down it will look a bit better

Totally agree, in comparison to 4000 series it's not a great generational uplift. But for those of us that skip a gen, it's great and fully intentional to appreciate that uplift.

I had an EVGA (RIP) FTW3 3080 for about £740 - so paying £979 for the 5080 FE circa 4 years later, I'm still happy with the upgrade.

I don't think the reviews have been unfair at all , if you look on what's actually happening

the 80 class card is meant to beat the 90 class of the previous gen where relevant but this gen cant do it cause its a cut down trash card, should be a 5070 or lower

I think there's an issue with mistaking it as bad hardware, vs a badly marketed product. The hardware is solid. Its still good. But for what you are getting it shouldn't be called a 5080 and shouldn't cost well over 1k
 
Reviews for products don't typically just compare it to the previous products performance exclusively, because a review is for someone who needs to buy that product now. A review should also compare a product against what is available to buy in the current market at its current price. A new OLED TV might have minor feature upgrades but it doesn't make it bad because it's only marginally better but costs the same price. Many of these reviews are using historic pricing, unavailable products and performance expectations as a comparison, and choosing to ignore inflation, supply Chain issues, wars, earthquakes, Ai etc.

The 9800x3d was a marginal increase over the 7800x3d but had really positive reviews, it didn't make sense for people with 7800x3d to upgrade to it. How is that different than the 5080 vs 4080?
