Gigabyte-RTX-5080.png

Pros:
  • DLSS 4 Frame Generation and Transformer Upscaling
  • $200 cheaper than RTX 4080 non-Super MSRP
  • No price increase over RTX 4080 Super MSRP
  • Compact dual-slot design
  • Extremely energy-efficient
  • Idle fan-stop
  • Support for HDMI 2.1 & DisplayPort 2.1
  • PCI-Express 5.0
  • Good video encode/decode hardware acceleration support
Cons:
  • Only small performance improvements gen-over-gen (except for multi-frame generation)
  • Very high idle/multi-monitor/video playback power consumption
  • Fans could be a bit quieter
  • Memory overclocking artificially limited by the driver

Video Reviews












I will update as others show up

Igors Lab:

RTX 5080 is only 8% faster than it's antecessor RTX 4080 SUper, making the most disappointing card of the new series so far

The RTX 5000 series really isn't a new generation of GPUs, it's just a refresh.
We'll have to wait another 2 years, before having a true next generation of GPUs.
But on a positive note, the RTX 4000 will still be a great GPU line for quite a while.
So anyone with one, doesn't have much of a reason to spend more money.

Damm, the 5070 should be a disappointment to. I was waiting for that, but now I should wait for the 18GB models.

Other than 5090
This one feels more like those nvfresh/rebrandeon days
Even the 5090 is really just a bigger (die not card) / more power hungry 4090. Generational improvements per core are definitely tiny.

I am not even sure the 5090 is the epic AI card people want to pretend it is. The memory capacity and bandwidth per watt is not really great, so you aren't going to see people with three or four of these like you do with 3090s for inference.

It will definitely train faster than a 4090/3090 but anyone doing training beyond hobby scale (i.e. SD LoRA) is using A100/H100 in the cloud.

Thing is 32GB for $2K is still pretty good for workstation side / local testing and inference. You can fit smaller to medium size models in memory with it.

Or might be able to get 2 (would be some beefy PSU) and do some local training from dev side.

Bigger cards really start jumping up in price quickly.

Exactly my thougts. Or maybe 9070 XT.
Thing is 5070Ti seems like it’s also going to be barely better vs 4070Ti judging by its hardware and 5080 “performance”.

And the rumor for 9070XT pricing isn’t particular promising now.

I might see if I can grab a 5080 from BestBuy and see what happens. And return it for 5070Ti if that performs better than expected.

I'm gonna wait until everything is released and extensively tested with many games. Then i'm gonna decide.

Oh absolutely, and since they don't make the older cards any more it's somewhat moot.

But you can get 4x 3090s (1400W w/o mobo/cpu/etc) for 96GB of inference capacity on a single residential / office 15A circuit where as you can't do 3x 5090s (1725W w/o a mobo/cpu/etc)

For LLM or video 32GB is just not enough for a lot of use cases. Totally great for smaller models, and again the 5090 is going to be a beast at training smaller data sets. Image guys are going to love it though. Flux on multi 4090 was always less optimal, and the 5090 will chew through these.

So at this point if we want to guess how much better the 50 series will be that we just look at power consumption? I mean the 5080 uses 360W vs the 4080S 320 which is 12% increase and it's 8% faster. Should we figure that since the 5070ti uses 300W and the 4070Sti 285 we'll see 5% increase in power so minimal improvement? (Oh well, at least the MSRP is $50 cheaper.)

It's a huge upgrade from a 3080, even if somewhat disappointing compared to the 4080.

After 4 years, paying 40% more for a 50% upgrade doesn't seem all that great. Other than path tracing, My 3080 still handles most things just fine. The few cases where VRAM is an issue, I can usually get around it by turning down some settings.

I'm not in any rush to upgrade, and the 5080 is doing nothing to motivate me.

I'm glad I opted for a well priced 4070ti Super even more now!! I'll opt for a top of the line card if the 6000s are a big step up.

I'm also on a 3080. I was hoping this would be enough of a lift to justify the cost, but that's a big nope.

Oh well. The wait continues.

I remember worrying that I was making a mistake getting a 4070 ti Super so late into the 4000 series gen. I paid £799. I definitely feel vindicated now though.

Is it just me, or is the 5000 series shaping up to be the worst gen ever? Unbelievably daft prices and multi frame gen as a key selling point really feels like it should be a disaster for Nvidia. Pity it won't be.

If Nvidia really wanted to make us laugh they could have just made a youtube skit or something instead of designing a whole GPU architecture.

Yea but those of us on 3000 series are starting to feel the heat of upgrading, if path tracing is wanted at least.

Although, the DLSS 4 performance mode being so good kinds of breath life into them. I'll have to evaluate if I don't just skip the gen.
 
Imagine a next gen 80 series not beating or at least reaching the previous gen 90. Gutter trash.
we´ve never had xx90 cards with such huge silcon differences to their xx80 counterparts before the 4090. Everyone who expected the 5080 to beat the 4090 without at least a full node shrink was nuts. And even WITH a nodeshrink from TSMC I´d absolutely not bet on the 6080 beating the 5090 which is literally a monster on die level.

This, it's just not happening anymore.

Depending on how low of a 3000 card people have I think that 4080 is still the sweet spot for a great upgrade path

I'm 3080 too and have decided not to jump yet unless other reviews are different. It's barely giving more per £ over my current card and I cant believe the 60 series will be this bad an upgrade.

For a 4080 owner it's bad... for a 3080, your getting that huge 4080 jump for (if you get it RRP) a lower price + a little extra.

Not ideal was hoping for a 15%-20% increase, but over the 5090's voltage and heat... I think I'm going for the 5080 anyway. The Monster Hunter Wilds beta was a joke on my 3080, I need an upgrade.

But they're not manufactured anymore anyway. If you find them they are at MSRP you would save $100 at best?

Like I know raster is disapointing for Blackwell, but if I were to pick a new card as of today when upgrading from a 3000 series, blackwell is the logic upgrade over Ada. When games start using Neural mega geometry, neural ray reconstruction, neural upscaler, neural skin, neural shaders, neural lipsync, neural... etc, Blackwell should age better. On top of having 2x, 3x, 4x MFG which again, I don't know if I'll like but the option is there.

5070 Ti maybe, waiting to see results. I'm only on a 3440x1440p 120Hz monitor so overkill doesn't make too much sense.

Or I skip entirely. Can't think of a game I can't play as of now really and DLSS 4 performance just revived my GPU.

One thing for sure, I ain't camping out for one :messenger_tears_of_joy:

I would just wait 9070/XT and 5070ti price/comparision

It's not about the money. I have several grand in my hobby fund that I could spend on whatever I want. I've been saving and buying very little for the last few years. I just hate the feeling of wasting money. The 5080 isn't interesting enough for my tastes, so a lower tier card certainly won't be.

I generally want to see at least a 50% performance increase before I upgrade, but preferably 60-70%. The 4090 had the performance but the price was too high. I'd like to see a card with 4090 performance and 20GB of VRAM for around $1,000. The 5080 wasn't going to get there, but I was hoping it would get close enough that I could lie to myself.
