RTX 3090 looks awesome, i want it, will an 9900k and PCI 3.0 bottleneck it?

[danygia]

I'm worrying about this.

Of course. Wait for next line of intel to come out as even an i9-10900K would bottleneck it.

You can't prove that. Wait until it actually comes out.

Specs of PCIe 4.0 are already out, and a 10900k is just barely the optimal CPU for TITAN RTX... 3090 is about 50% better and uses PCIe 4.0, so you really should wait until the next Intel release to jump on the 3000 train.

You really don't understand specs do you.

The cards will be fine on pcie gen3, I suspect a 9900k will also be more than upto the job seeing as it isnt breaking a sweat with a 2080ti and unless the game can use more than 8 cores, not much is any faster in reality still.

Kurumi, you realise that if a 10900k is barely enough for a rtx titan, then your non overclocked 10900X is holding it back and bottlenecking it as its notably slower than the K variant.

im worried about it too, i got a i7 10700k and i hope the rtx 3080 can run at its best with it

just don't play at 1080p problem solved

[sebo]

no bottleneck. anyone who says otherwise is purely guessing. first, look back at previous generations. pcie 3 graphic cards weren't limited by pcie 2 motherboards. pcie 3 x16 is as fast as pcie 4 x8, and it's not going to bottleneck that. plenty of benchmarks floating around in the past comparing 3.0 x8 with x16 and made zero difference in gaming.

BUT lets stick to the facts:

pci gen 3 = 8GT per lane @ x16 = 126 GT/s
pci gen 4 = 16GT/s per lane @x8 = 128 GT/s

8GT/s = 985MB/s
985MB/s = 7.8 Gb/s
7.8 Gbps x16 lanes = 125 Gb/s

I'll leave you the rest to figure out.

Bottleneck doesn't depend on resolution. It depends on a number of things, a few off the top of my head are, framerate, the game in question, the bus bandwidth (if he's running in x8 mode), and the physics/scene complexity of said game.

Well, this is one of the largest leaps in generation performance I've seen, so there could be reason for speculation; and there are some new features - if I'm not mistaken Nvidia said about a new storage to VRAM feature thing, that could cause a large amount of bandwidth usage on the PCI-e lane. So it could potentially make 3.0 not enough. Though, like I said, potentially, I'm still waiting to read more info on it.

Worthless math, here's the real review

i highly doubt a 6 core with 4.3 ghz would bottleneck a 3090 if that's the case what kind of a beast are we lookin at xd

also read this bit just now:

As for the performance impact from PCIe 4.0, we’re not expecting much of a difference at this time, as there’s been very little evidence that Turing cards have been limited by PCIe 3.0 speeds – even PCIe 3.0 x8 has proven to be sufficient in most cases. Ampere’s higher performance will undoubtedly drive up the need for more bandwidth, but not by much. Which is likely why even NVIDIA isn’t promoting PCIe 4.0 support terribly hard (though being second to AMD here could very well be a factor).

as i've said, there isn't a card now that will bottleneck 8x lane gen 3, let alone saturate x16 lanes.

Who really knows at this point( i think it shouldnt bottleneck though). that GPU can apparently play at 8K.

[Carlsberg]

The card needs 3 slots, a 750w psu and has a price tag of around $1500. Couple that with the price of the rest of the system and a 4k monitor, who in reality is even going to consider one?

Just to play a game? cmon ppl, how many will they actually sell? I know there are people who can afford this but not mainstream, most will buy the intermediate cards and trade price/performance to their respective budgets.

Well not me anyway. I am happy with my gtx 1080 ti for now. Not fussed about ray tracing. Any upgrade is a hard sell. When unreal engine 5 games come out, then maybe a 4000 series one for me.

You don't need a 750w PSU or 2160p monitor though...
