3080 benchmarks are in! Are they good?

TLDR:

If u have old and/or slow CPU, and u want to get a 3080, make sure ur running 4k.

You could use DSR in the meantime.

You can still game at 1440p using your current 1080p monitor using nVidia DSR. I do that too and I play GTAV at 1440p on my 1080p monitor and GTA4 at 2160p.

I guess that makes sense. Would it look any good though?

At 1080p you'll probably have a roughly equally CPU/GPU bottlenecked system. 

Wouldn't my CPU bottleneck the 3080 though? Why would it also be the other way around?

[Tieox]

I am pondering now if the 3070 is worthwhile upgrade for a 1080 for 1440p 165hz gaming?

[BlueChinchillaEatingDorito]

Well that's just marketing isn't it? 80%? Well that's close to 100% so let's just say double the performance. It rolls off the tongue nicer and really gets peoples' attention. But it's still no slouch so I don't see a reason why people should be absolutely disappointed. Would you rather get 80% improvement or just the 20% generational improvement that's typical in the tech space? 

[MrBrightSyde]

Well at least my guesses on the power draw were right. 325w stock, 375w OC. 650w is enough for most people.

As usual, a good product that seems a little better than it actually is due to modern marketing practices.

Don't rush and buy cards wait for RDNA2 to be out

I'm not in a rush to upgrade, it would be nice if AMD had something that could at least compete with a 3070 with more VRAM, but i'm not getting hyped for anything from AMD.

And wow that 325w power draw at stock, I wonder how much power AIB cards will use.

[DeScruff]

So Nvidia showed the numbers that put the card in the very best light compared to the last generation.
I feel like we go through this every generation, and every couple of generations a hype train gets built up.

I literally told everyone that Nvidia lied on the Doom test with evidence, and that they exaggerated.   What they were doing was using older drivers for the 2080 Ti to misrepresent data.

...did they though?

[AnonymousGuy]

Seems like the 3000 series is going to be a pretty convincing win along the lines of 900 series -> 1000 series.

 

2000 series owners are getting it both ends.  Crushed on resale value and never really had good enough performance for 4K anyways.

it looks like they over exaderated how much faster the 3080 is over the 2080.

how so?

See above I never hit under 144 with mine, and they are using a higher binned with an older driver.

So now you're implying not just that Nvidia purposefully gimped the 2080Ti to make the 3080 look better in comparison... but also Techpowerup?

And Eurogamer too, apparently:

Spoiler

 

Maybe they just ran their benchmark in a different level/area, as opposed to the one you're in in the screenshots? From my experience playing the game performance varies quite a bit depending on the level and where exactly I'm at in it.

I laugh at the so called bottlenecks. It was never a great way of thinking unless you're ludicrously unbalanced, but any consumer 6 core since coffee lake or zen 2 should be fine for any regular gamer with a 3080. I propose the "good enough" decision on if if you should pair a CPU and GPU together. In short, both have to be good enough to do what you want it to do. That's it. It doesn't matter if one is limiting the other as long as it reaches the performance target.

How dare you! I'll be getting the 3090, and running at 720p!

You can have bottlenecks though that aren't desirable (for ex 2200g and gtx 1060) but in the case of 3xxx I'd rather see it as "reserve" as long you have a decent CPU (3600 and up)

900 series -> 1000 series

Nah this is never coming back, not with conventional tech. Moore's law (or rather the inevitable death thereof)  is a real thing and not just a meme .

I mean...is this not already happening with 2000 -> 3000.  The 3080 is already about 30% better than a 2080Ti so 50-60%  that happened from the 980Ti to the 1080Ti) is plausible for 2080Ti vs 3090?

[-rascal-]

My 2-cents.

You can't just compare the TFLOPS numbers; 2x TFLOPS =/= 2x real life performance.

RTX 3070 > RTX 2080 Ti because TFLOPS numbers...cuz nVidia said so...

 

RTX 3080 still a decent card, though.

I guess the biggest things I hate about "bottleneck" posts are two fold:

1, the same "bottleneck" wont happen in all possible variations of settings. You have to define the test case.

2, for some reason it is better for the GPU to be limiting, not the CPU.

 

I can kinda understand #2 if you're doing a tight budget build, where you probably want to overspend on one part or the other.  The first part is usually not well defined, and varies enough with game title even if you pick a resolution and quality class target.

 

While on the topic, the other one people have been flooding the forum with is the PCIe 3.0 or 4.0 question. It was linked somewhere earlier in the thread, but TechPowerUp did the testing, and we're looking around 1% difference. It is really not something to be concerned about. They have also done testing putting red and blue CPUs against each other, specifically 3900XT and 10900k. In short, red is still behind on average. 10% down at 1080p, 7% down at 1440p, and near enough parity at 4k. The PCIe speed difference is nothing in comparison.

RTX 3070 = RTX 2080 Ti because TFLOPS numbers...smh

 

RTX 3080 still a decent card, though.

I think it's a much better measurement than reviews or benchmarks because both inevitably will be biased in one way or another (and not even necessarily on purpose).

 

 

The fact that you don't get 2x in-game performance with 2x TF is something one should know though I agree.

 

 (Though, you do, "in theory").

Shouldn't the 3090 be compared to the RTX Titan though?

[Xaiux]

I recently upgraded to a 1440p 144hz monitor, and my 2070 is struggling even without any RTX games yet. I think I might spring for a 3080 and try to get some resell value for my old card, thankfully my CPU isn't a bottleneck at all.

just adding on this, i think for last gen we were able to somewhat recommend a 3300x/3600 up to a 2070S. For this gen it's important to note that every cpu can bottleneck a 3080 under 4k, and even sometimes at 4k. We need faster cpus, waiting for zen 3 will make your 700usd gpu run faster.

 

Here's some key point i saw

 

In general performance was ~20% faster

RT on it jumps to about 25-30%

CPU bottleneck is severe in some cases

PCIE bottleneck =1%

If doing a new build, wait for zen 3.

I looked at the 3090 specs again and am now expecting the 3090 to be 25% faster than a 3080

3070 will take the price to performance crown, but the 3080 is king for now

 

Just waiting on the hero that buys a 3080 to use with a 1080p/144hz monitor to play RT on/DLSS off.

No, your CPU is fine enough. No need to worry. Just use DSR and crank up the resolution to 1440p or even 2160p if your GPU can handle it.

Currently using my i7 4770 and GTX1080Ti and I too use DSR. No problems.

[suicidalfranco]

Tfw I don't feel disappointed about it cause all i want is a 1080p silent system

[RejZoR]

Part of me wants to just grab RTX 3080 and call it a day and my other part of me wants to wait for RX 6000 series and better general availability. The only problem is Cyberpunk 2077 getting released in the meanwhile and I'd really like to play it all maxed out with ray tracing and all that stuff. Also given the amount of raw compute horsepower should help me run RTGI ReShade shader easier on non RTX games since it's done through regular shaders. Argh.
