Which CPU to get to maximize gpu utilization?

Hey folks so im currently running a R7 1700 which i have been for the past 3 years and has done me well but now as games are getting more demanding and i have a RTX 2070 Super and game at 1080p a CPU upgrade would be the logical choice im assuming?

ive done a few benchmarks in games which show u how bound your GPU is 100% being GPU bottlenecked and 0% being CPU bottlenecked in Gears of war 4 and 5 plus Shadow of the tomb raider at Ultra settings im getting from as low as 5% bound to around 50% bound.

i want my CPU to last another 3 years and have no expectation at changing my monitor to 1440p as i prefer the higher frame rate than how good a game looks.

also would need a motherboard for my new CPU my Trident Z ram should be good enough to keep?

im Leaning towards a 5800x and B550 which would be about a 450 pounds upgrade after i sell my current CPU/MB do you's think that's worth it?

Also the games il be playing are Cyberpunk 2077,Destiny 2 and Cold War so want to have it built before 10th November.

Any Help is Greatly Appreciated :)
 
Im a Ryzen noob (waiting for first one, 5900x)

Would your current board not support a 3900 or something? Would be enough of an upgrade, without a new board probably?
 
Yea I'm definitely going to wait for reviews I've been hearing people say the NDA isn't going to lift until there release which sounds stupid imo who's going to buy a product without first knowing how it performs I think they will lift NDA on the 28th when they announce there new GPUs.

I think you're on the right track. 5000 series will be blazing fast and will help to keep the GPU fed.

from what they showed already its definitely looking good... lets hope that they've learned from previous launches and will not overpromise this time..
 
they did... but their biggest advantage is there biggest issue..
chiplet design allows you to cheaply build high core count cpu's .. but it has latency issue.. great for work but gaming needs low latency and high clocks..

zen 2 (ryzen 3000) is already good enough and the price is right.. but to claim the crown they will need to beat intel in gaming
 
Ryzen 7 5800x, Aorus B550 Elite and Wraith Spire RGB cooler comes to around £577

or

Core i7 10700k, Aorus b460 Pro AC and a half Decent Air Cooler works out around £540

I Want the Aorus board as been using one for 3 years and had no trouble plus need 2 m.2 slots for my Dual 960 Evo's

Lets just wait for benchmarks but less than 40 quid of a difference for hopefully 5-10% more performance and PCI-E 4.0 for future upgrades.
 
Its a tricky, one if I understand correctly Ryzen always suffered a latency penalty with threads going from CCX to CCX incl. a CCX in a different CCD.

With Ryzen 5000 they have increased the max cores per CCD and increased the cache sizes (among other things) however:
- 5900x is 6core CCX over two CCD (chiplets) <---- two disabled cores per chiplet, possibly the slowest therefore higher boost potential
- 5800x is 8core CCX with one CCD <----- No risk of latency, but only £100 less than a 5900x
- 5950x is 8core CCX over two CCD (chiplets) <--- Binned 8core chiplets but still CCX - CCX latency potential and higher heat output also double the price of a 5800x

I suppose the good news is there are no bad options, it just makes it harder to choose and differentiate on gaming performance alone 5800x is probably going to give you all you need for years to come if you don't multitask

5950x is probably the best because I believe you can shutdown cores, in theory I guess you could switch off one CCD entirely and try to boost all-core on the stronger CCX/CCD to give the max perf for games, sounds like an expensive option though

When you say multitask. A second monitor with discord, chrome etc open. Would that count. I was going to get the 5900x

No not really, by multitask I mean playing a PC game whilst managing streaming software or rendering video i.e. something that actually puts the cores to work as opposed to background tasks and low demand threads

Discord and Chrome consume relatively low amounts of CPU resources, 8 cores is plenty for that work load.
 
I'm in the same position as the OP (Ryzen 1700 @ 3.7GHz all cores) but as I game at near 4k (5120x1440), I'm just going to drop in a 3700x when they get to about £200ish and that should last me until AM5. I figure that as I game at quite a high resolution, I will be pretty much GPU bound even with something like an RTX 3080.

My monitor is 3840x1600 so om thinking the same, for now drop in a 3600 or 3700x.
Probably get a couple of years out of it then do a full new build
