And the 5090 is so different in core count and memory bandwidth that it will be hard to extrapolate the 5080 performance from the 5090 results.

Daniel Owen did a video on this:

If you compare the Far Cry 6 and Plague Tale: Requiem numbers (i.e. apples to apples without 2x frame gen) then it looks like nVidia is targeting about a 35% increase gen on gen.

For the 5070 that puts it near a 4070 Ti Super at significantly less money and $50 under 4070 pricing
For the 5080 that puts it slightly ahead of a 4090 at 4080 Super pricing
For the 5090 that is 35% increase in perf... for 25% increase in $$$.

5090 reviews on Jan 24th -


Looks like Papa Jensen is worried it won't be in as high demand as 4090 was...

I don't get the logic here.

Usually people are concerned when the review embargo is on the same day sales start, basically so FOMO buyers pretty much have buy before they can absorb the reviews.

That's kind of the case for the 5080, but the 5090 has reviews much sooner, which means people have plenty of time to absorb the reviews before they can buy. That's more of an indication of confidence than worry for the 5090.

Even the 4090 has issues with CPU still bottlenecking at high resolutions, the 5090 might suffer even more there.

The 4090 is ~45-60% faster than 4070 Ti or 4070 Ti Super, and the ratio of shaders and bandwidth that the 5080 has with the 5090 is somewhere between those two. I'd expect a basically similar ratio between the 5080 and 5090.

Early reviews are great, it's just weird that we get the 5090 review a week early and only launch day reviews on the 5080. Seems suspiciously like they want a week of great press for the big increase the 5090 should bring before they launch a 5080 that probably won't be a terribly impressive jump over the same priced 4080S it's replacing.

People way overthink this stuff IMO. Unless you are FOMO buyer getting ready to order the moment they will take your money, why would you care at all about reviews a week before or day of the release.

But if anything this reflects more poorly on the 5080, than the 5090 which was the claim I was responding to.

Videocardz article suggests there were late BIOS tweaks to the 5080 that made it hard for AIBs to stick with the original Jan 21st embargo for the 5080.

Oh absolutely, I agree with you. Review embargo coming off a week early is definitely a sign of confidence in the 5090.

I pretty much expect both cards to sell out as soon as they launch and be up on StockX a day later though. We'll see how it plays out, but I don't see any stock of 4080/4080S in the States within a couple hundred of of MSRP. Nvidia's done a masterful job of managing supply ahead of the launch.

Those numbers don't make any sense.

The 5090 has 33% more SMs.The 5080 has 5%, 5070 Ti 6%, and 5070 4% (over 4070 NS). You'd expect the gap between the 4090 and 5090 to be 25-30% more than the other ones.

NVidia data is kind of terrible. I think they are using DLSS performance mode for scaling, so it's running a 5090 at 1080p real resolution, so much more likely to have CPU limitations.

Need to wait till the end of the month for real benchmarks.

They certainly picked games with settings that would ensure CPU is not a bottleneck, but to make sure they run quickest they'd rationally use the best available CPU on market - 9800x3d.

You would think they would do that.

But check Far Cry 6 results here:


At 1440p 4090 is 13% faster than 3090 Ti. (massive CPU bottleneck).
At 4K 4090 is 50% faster than 3090 Ti.

9800X3D will shrink those gaps, but 1080P is going to make them worse, so we need real 3rd party testing.

Far Cry 6 does not support DLSS (just double checked it) - which is what made it notable in that group of games

Ooops. My bad, I remembered fine print that they were using Performance mode DLSS, and thought they had it on for everything.

Still have to wait for real reviews to see where the performance is going. Only the 5090 has a significant jump in active units. It's gains should be head and shoulders above the lower models.

Think most of us have been around the merry go round enough times with how canny nvidia marketing is.

5090 is obviously going to be impressive. Once again the fastest GPU ever, and a tangible boost over the 4090, that will get that tier of buyers to buy another halo card again.

5080 is going to be underwhelming. Probably the most underwhelming 80 card in a long while. Slower than 4090, not much faster than a 4080S. We have the specs and there doesn’t look to be anyway around this, outside of DLSS4.

I think we’re almost certainly getting an 80ti this gen. Defective 5090 dies once amassed, released as 5080ti for $1500-$1600 sometime in the fall.

RTX 5090 uses a a cut down GB202, so almost all the dies with a defect will still be used for 5090 GPUs. There might be a very small number of dies that can't meet 5090 specs, but could be used in a cut down mem bus configuration. I don't think there would be enough to meet the demand for a 5080 Ti that bridges the gap between the 5080 and 5090 though. If anything, they might do something like a 5090 with a slightly narrower memory bus and higher memory clock speeds. Hell, they could put 3GB modules on it and call it an upgrade. 5090 Super 36GB 384bit GDDR7 36gbps.

I don't see why they couldn't do a 384-bit, 24 GB cut-down version of GB202 that's half-way between a 5080 and 5090... GB202 is a really big die, so given enough time, they could gather enough defect chips to meet those specs. Only real problem with it is it will likely only be 10-15% faster than a 4090 at the same launch price as the 4090.
