Power – Temp – GPU Clock Frequency
Power
The TDP of the NVIDIA GeForce RTX 5080 FE is 360W. In our testing, we hit about 357W on board power, in our test. In the same test, this puts the power draw definitely higher than the GeForce RTX 4080 Super FE by about 17%, or on par with the power draw of the Radeon RX 7900 XTX. It does use 17% less power than the GeForce RTX 4090 FE.
Temperature
Interestingly, the NVIDIA GeForce RTX 5080 FE was the hottest running GPU according to the GPU Temp in GPU-Z. It hit 71.4, which is on par with the temperature of the larger and much faster GeForce RTX 4090 FE. It’s much warmer than the 65c of the GeForce RTX 4080 Super FE.
GPU Clock Frequency
The boost clock on the NVIDIA GeForce RTX 5080 FE is 2617MHz. According to our real-world in-game GPU frequency test, we are hitting a GPU Boost up to 2760MHz-2790MHz while gaming, so it does boost a bit higher than its boost frequency specification.

No surprise here, given the specs, I didn't expect the RTX 5080 to do any better.
The RTX5070Ti hopefully will be a much better option as it's supposed to be right behind the RTX4080.
I'm very disappointed, I can't remember the last time a next gen x80 card wouldn't beat or at least meet the next up tier.
I remember when I got my 1070 that it was supposed to be on par with the 980ti
Looks like 5080 is a dud. I hope people read reviews before buying them on ebay for hundreds more. Maybe holding on to the 4090 is a good idea. But, the 4090 just increased in resale value!
So why is the 5090 not anywhere twice as fast as the 5080? what's holding it back?
Honestly, I'd love to see some deep dive on if the 5090 is being constrained by CPU. I've seen some side mentions on a couple sources saying it seems that way but no deep dive.
Reminds me of the 1000 series to 2000 series jump, only without the DLSS carrot there to give you a reason to bite.
On a side note, I've seen a few posts claiming that the new transformer DLSS mode is much more improved quality than the old one. So much as DLSS balanced mode being indistinguishable from quality mode and even performance mode being much better than before.
That should be pretty easy to test with time available.
System 1: Ryzen 9700X Down clocked, or even just set to 65w
System 2: Ryzen 9800X3D pushed as high as you can go with clock
run both systems at 4k and see if there is any significant difference
I mean it's a BIT more than that. You might want to use Intel's monitoring tools to see how things are working and better project where there is a bottleneck between the platforms for differences.
That's an interesting idea, give me some ideas (examples) of what to test to accomplish this. I also think it is true that the 5090 is being held back by the CPU, I said as much in my review.
Thanks for that suggestion, as I said above, I personally think that is a great idea to test. Right now, something like that wont be soon, but I've got it written down in my potential reviews doc.
It would need to be basic. at 4k whatever refresh is the GPU at 100% while the CPU is running at max ghz high utilization across cores? That's how I would logically think a held back device would look.
But it would need to be a slim test.. like perhaps raster only... I'm not sure on that.
Jay has a video on how to use the intel tool to track and see if the CPU or GPU is throttling. *shrugs*. It seems kind of esoteric to me. All the info I've seen calling out CPU throttling has been at higher res where NORMALLY that would be at lower rests... so it's interesting.

Presentmon is the tool that you can use... just a idea. Jays video has some info on how to use it but there are better tutorials online.
Gotta wonder if a cutdown GB202 die is on the table for a $1499 5080 Ti w/ 24 GB VRAM.
It appears the 5080 is a good overclocker. If that is consistent across a bunch of samples then it's a great candidate for water cooling to open up some possible additional headroom.
Good point. A lot of folks are complaining about how close this is to a 4080 SUPER but things could get really interesting when OC'd and liquid cooled since you don't have to worry about hitting a 600W power limit for the cable.
