I'm interested in upgrading my 2700x specifically to fix issues that I experience in games where the CPU holds the GPU back. AC:Odyssey is one title that really seems to suffer with this, and also Far Cry 4 & 5. Is it likely that the improvements with Zen 2 can remedy this? Is the IPC improvement enough, or is it purely single core clock speed that's the problem? If so then I'm not seeing a massive improvement there according to the figures being banded about.

I'm concerned that I'll end up with very little improvement after the upgrade, and it's getting a little bit frustrating as Intel just feels totally dead end and flawed right now.

Resolution is 1440p and target frame rate is 100-144Hz.
 
we can hope. What little we know about the ryzen 3000 series, suggests that they will have a big IPC improvement and a fair clock speed improvement. Lisa also specifically called out improved core to core latency which is one of the 1st and 2ng gen ryzens biggest weaknesses. If its as good as she's said then yes you'll see improvements, as too how noticeable they will be is questionable.

Honestly I don't know if it will be worthwhile, at least not at launch prices. I suspect at best you'd get the same performance in gaming as a 9900k which at 1440p even with a 1080ti is only a few % higher than a 2700x


 
Please do not confuse clock speed alone with CPU performance, IPC is the more important metric, AMD's IPC right now looks like it is potentially stronger than Intels, so strong infact at lower clock speeds it is bypassing Intels, so where an AMD Chip is hitting 4.5ghz an Intel CPU will need to hit 5ghz to keep up with it.

What we need to see right now is single threaded benchmarks run on both 9900k and Zen2 to ascertain exactly where the best single threaded performance lays. Multithread performance AMD already owns that crown, and we now think they probably own the Single threaded crown as well.

Metrics are showing that the Zen2 IPC is 15% faster than the 2700x and they have a 200-300mhz boost advantage as well, this is without any information on overclocking as well.

Right now i would wait to see solid Zen2 benchmarks, i think we are about to see something quite special.

Is that high refresh improvements? The issue I see is that there is room left in the GPU tank but it can't be utilised because the CPU is holding it back. I think what you are describing is extra FPS squeezed out when the GPU is already at 99% load - apologies if that's not what you meant.

Yea, it's early. I'm really interested in user benchmarks after release as there are various scenarios that reviewer benchmarks just don't seem to take into account.
 
Imho it depends on Res , my main Sig has issues at my current res ( 2560 x 1080 ) battlefield even which is renowned for using most of any CPU that's given to it can't push my 2080 to beyond 80% util most of the time , sometimes it peaks but it's rare. Add 15% performance increase to the CPU with my mostly basic math it still won't get me a concistant 100% GPU util . Some games it will be even worse . But this allows me some extra room for down sampling to get the most use from my 2080 with affecting my overall frame rate as thata limited by the CPU .
 
What FPS are you trying to hit in FC5? I tend to use the NV recommended settings which in New Dawn and using a 2080 is only about 70 FPS @ 1440P.
I've done some tests in the past comparing a 6700K to a 1950X, including FC5 using the recommended NV settings, and saw hardly any difference (2-3FPS) using the same GPU (1070 Ti) and maybe also a TXP (can't remember 100%). I'd have thought the 2700X less likely to have a problem.
