RTX 3080 review is out! Really big gain in performance. Limited by CPU on certain games.

Only 21% faster than 2080 ti at 1440p.
I’m going to wait for big navi and better CPUs.
Yeah, it won’t be able to flex its muscles at 1440p. Unless the game is pushing the graphics. Definitely for 4k at the moment. Need to see more ray tracing benchmarks.
Very very few play at 4k.
Seems to be around a ~20% uplift at 1440p over a 2080 ti, and a ~30% uplift at 4k, conventional rasterization.
It means CPUs are too slow.
FYI, TPU did a whole series of reviews you can check out. In a nutshell based on the entire TPU gaming suite;
RTX 3080 on PCIEx16 4.0 is roughly 1.1% faster then the RTX 3080 on PCIE 3.0 x16 and that is regardless of 1080p, 1440p, and 4k.
With the RTX3080, The intel 9900k OC to 5ghz is just under 9% faster then the AMD 3900XT at 1080p, under 7% at 1440p and 1% faster at 4k
With the RTX3080, The intel 10900k at stock is just 10% faster then the AMD 3900XT at 1080p, 7% faster at 1440p, and 2% faster at 4k.
got a link for that?
edit: nm found it

Toms shows an 18% FPS increase in their gaming suite on medium settings going from the 3900X to 10900k at 1080p. About 13% increase with the 9900K at 1080p medium settings.

Any RT shadowlands benchmarks up yet?

youtube or reddit fan boys would be your only place to find such info. SInce SL is still in beta, no legit reviewer is going to touch it until its final.
Already expected CPU bottleneck before the review. Nvidia pushed RTX 3080 a lot.
It’s nice to see 100+ FPS on 1440p when CPU doesn’t bottleneck too.
Looking at TPU’s review the data seems to indicate the 8700k at 5ghz won’t really be a bottleneck any more than anything else. 3600 was slower than the 3900x, but that’s probably due to clock speed.
I’m honestly surprised nobody did a 10600k pairing as that’s going to be a really common CPU for gamers.

Eventually someone will do it. Zen 3 is coming. Maybe that will tell you more on RTX 3080 CPU bottleneck.
CPU bottleneck also depends on games.
Well this game for sure doesn’t give two gnomes about cores. So there’s that.
Shadow of the Tomb Raider is probably one of the only core-heavy games that I see on there, but most stuff isn’t that well optimized for the extra resources.
Don’t even wanna look anymore. I only see 1 thread constantly loaded. The rest of the threads does have processes but barely.
According to TPU there was no difference between an OC 9900k @ 5ghz and 10900k at stock at 1080p. Both TPU and Toms use an OC 9900k in their test bed so I would assume an OC 8700k would be in the same ballpark as the 9900k.
Assuming they are faster then on OC 9900k
If you have a fast enough CPU, the wow engine will dump as much rendering as it can on one core
Most i’ve ever seen my 6/12 utilized while playing wow was 38%.
In FFX14 it’s gone as high as 47%.
I can’t think of many games that have actually pegged the whole thing yet. I guess I really haven’t looked.
typically, I only see it while the game is loading something

I just want to say that I know this is the conventional wisdom, but I recently upgrade from a 4 core i5 7600k overclocked at a hot 5.0ghz with near constant 100% cpu usage in WoW to a 10850k at 4.9ghz to 5.3ghz and see massive performance increases with CPU usage rarely exceeding 30% on any core.
I know WoW doesn’t care about multicores or whatever but it sure seems to take stress off the other cores having more of them?
WoW recently in 8.1 got an update that improved multithreading performance. There’s uplift in all systems that have SMT/HT or more than 4 physical cores - I noticed an improvement on my 8700k.
That said, it seems the scaling stops at 4/8 in this game. Unfortunately you had a 4 core without SMT/HT, and it shows especially after 8.1.
I said what I said because most modern mid-range CPUs nowadays are 6 core chips with SMT/HT, and scaling past 8 or so cores isn’t really beneficial in most games.
Your case is just the other end of the extreme.

No bottleneck when using RT shadows. People have reports 20-50fps
