I've also thought of buying a pair of 2080tis for SLI. Depends which perform best although support for mGPU is fading fast.

An RTX 3080 @2.1Ghz exceeds the performance of the RTX 3090 @ 1.7Ghz

- Start date
I was also thinking of keeping my 2080ti and buying a second one now there going for cheap prices
But i hear MS FS 2020 doesn't support SLI/NV link and that about the only game i play at the moment that i could do with more GPU performance for
So it not really worth me buying a second 2080ti
Some of the AIB cards will go to 500W..................
1. Yes if you can afford one
2. But - Only if cooling will allow for it (e.g. if you wanna spend even more on a RTX 3090 with a hign end cooler). I heard non reference / custom 3090s are gonna be sold for ~$2000.
I really doubt the temps are gonna be the same as the RTX 2080 TI, as the RTX 3090 has a 100w higher TDP.

The 3090 has 20% more cudas and 23% faster memory speed. That may equate to around 30% perhaps more over the 3080 especially when overclocked as both cards will likely run at the same approximate speed.
Even then going from stock to max on the 3080 will yield less than 10% so it’s unlikely to come near the 3090 especially once both cards are overclocked and likely running at the same speed.

But will it go to 11?
MS FS2020 doesn't in DX11 but I bet they will support it when DX12 version arrives. £1 says it will, either way unless it does it will be unplayable 4K ultra over NYC with 2080ti SLI and/or 3080 unless something changes fast. 20-35fps with trackir is air sickness inducing. I suspect AMD may have some secret sauce to apply to the problem.I was also thinking of keeping my 2080ti and buying a second one now there going for cheap prices

Any idea which ones?
Just saw earlier today the gigabyte auros xtrme 3090 was listed on come Chinese etailer with a boost clock over 2000.
It's a strange comparison, basically the best clocking 3080 against a throttling 3090.
A better comparison is the best clocking 3080 against the cheapest 3090 at its published boost clock, the minimum guaranteed clock.

I also found that the RTX 3080 clocked @ 2050 Mhz would be equal (or a tiny bit ahead) of an RTX 3090 @ base clocks, in terms of TF count, pixel rate and texture rate.
I'm just using the info / stats listed on Techpowerup, personally don't see the point in comparing to an overclocked RTX 3090 (we know what would win), the point is to see if a much cheaper overclocked GPU can offer similar performance to an RTX 3090 running at the specified Boost clocks.

it all depends if the both boost to the same amount though.
let’s say due to the chips being so poor that a 3080 can only boost to 1900 but a 3090 boost to 2200. Then the gap becomes wider than the 20-30% at stock.
I don’t ever see the point in comparing an overclock lesser card to the next highest card in the range at stock. You may as well say that an overclocked 3070 will match a 3080 at stock.
not sure what point you are trying to make?
Sure, there will be some variation on the boost clocks of the RTX 3090. The point is that a factory overclocked model could be about as fast as an RTX 3090 @1.7Ghz - That is the boost clock that Nvidia is guaranteeing all RTX 3090s can run at. You *might* get higher than this on the reference model.
We have no way of knowing at this point what the max boost clocks of every RTX 3090 will be.
We can debate about the values of boost clocks all day, and the silicon lottery but the fact above remains.

Temps will be fine on the 3090 and it won't have any problem getting to very high clock speeds.
I have CPUs that can use twice as many watts as the 3090 when overclocked and can reach high clockspeeds.
When you overclock something like a 7980XE you don't ask "can my PSU handle it" you just use two PSUs lol.
As to temps don't be surprised if the FE 3090 actually runs cooler than the FE 2080 Ti.

Big difference in the coolers fitted to the cards, the FE 3090 has a far better one than the 3080.
The performance will be there on the 3090 as it is nearly twice the price of the 3080 and people would not buy the former if it did not come up with the goods.
