4k 120hz CPU impact?

[MaXxBoulton]

If 4k@60fps is gpu limited, how would adding more gpu load in the form of 120fps load the cpu up? It would just add to the gou bottle neck

It isn't limited to 60fps with NV 3000 series cards. It really depends on the game.

LGA1700/AM5 are pretty much guaranteed for 2021, as is DDR5.

Do you have a source / sources of info for this? All i’ve read so far is ‘maybe’

I'm not saying the card is limited to 60fps what I am saying it the limit was cards can't push 60fps @ 4k.

The new cards are stronger and can push 60fps @ 4k, but can they push 120fps at good settings?

The limit would still be the gpu.

They can push well above 60 at ultra settings. They can't hit 120 consistently so Gsync is essential, but what isn't clear to me is how the 5000 series CPU will aid that. My gut tells me the difference will be negligible when compared to a 3700x but I can't say that for sure.

Zen 4 isn’t going to be out in 2021 when Zen 3 launched in Q4 2020, it’s going to take until q2 2021 for all of the zen 3 SKUs to be released and in good supply.

Then you have a Zen 3/+ mid cycle refresh to fit in if there’s going to be one.

Zen 4 is more likely to be Q1/2 2022 at the earliest. It doesn’t look like intel has a response so I doubt they’ll rush their fine wine. 32gb of decent DDR5 is also going to be mega money compared to the £130 you pay for DDR4 now with little real world tangible benefit in anything GPU bound (GPU is where the material gains are needed in most games, as with Zen 3 benchmarks, most games are only CPU bound when you artificially lower the resolution and settings and put in a £1500 GPU, that’s just not realistic).

To answer the question, I doubt you’ll have issues with a 3900 at 4K 120, I doubt you’ll even be able to get 120fps from the GPU in a modern or future AAA (like cyber punk) game from a 3090 at 4K anyway, especially with ray tracing on. The vast majority of games just don’t run like doom eternal.

If you find yourself CPU constrained (you won’t) then just upgrade it when the time comes. I think the only CPU limited game at 4K will be FS2020 which runs like a complete dog on everything. It’s game engine just appears to be poorly optimised and relies heavily on a single core.

You need to track usage. If your hitting 100% gpu usage no cpu will change anything

Google it, hundreds of leaks/roadmaps/articles on both platforms. Of course things could be delayed, though as you can imagine Intel are working all hands on deck to launch a counter attack with both Rocketlake (works on existing Z490 motherboards) and Alder Lake (LGA 1700 next gen platform).

If AMD want to keep the gaming performance crown, they'll need Zen 4 next year. They only just took the gaming performance crown with Zen 3, verses 5 year old Intel Skylake and 6 year old Intel 14nm. Intel's bat is winding up for what they hope will be their knockout blow, just means we win as consumers

They push between 60 and 120 FPS at 4k. Looks a hell of a lot better than 1080P/1440P imo, and is silky smooth on OLED's (#CX48 master race)

I hope this is true but can’t say i believe all leaks, roadmaps and articles on the internet.

Well on a screen that big it's bound to because of the pixel density, when i upgrade to 4k it will look even better on a smaller monitor and not even have to worry about burn in of OLED to boot.

 

[b0rn2sk8]

Intel are not worried about the gaming performance crown, that’s just marketing nonsense to people like us which is an absolute niche of a niche. Go and ask joe blogs off the street and ask them who AMD are or why powers their PS5/Xbox.

There worried that they are losing market share left and right in the data centre. That’s where the money is made. They also have ARM coming over the hill in a pincer movement for the consumer space. It isn’t all about AMD.

what a silly thing to say, of course it looks better because of the pixel density

They push between 60 and 120 FPS at 4k. Looks a hell of a lot better than 1080P/1440P imo, and is silky smooth on OLED's (#CX48 master race)

are you saying your 3080 can push 120fps? because if you can and your only using a 6700k then this thread is done and can be locked.

now.. looking at benchmarks from "IGN" the 3090 with a 10900k on ultra setting @ 4k, hits around 80fps average over a group of AAA games

I suggest you re-read my post. Note the part where I state "between 60 and 120FPS". You quoted this specific part of my post, so you've read it. If you can't understand what 'between' means, I'd suggest booking a GCSE English refresher course, once they are available post covid.

in what games dose your setup hit 120fps

 

[Rofflay]

As someone who has been on 4k 120hz for two years nearly you will not hit this in new games imo. Resident Evil 2 or 3 or AC Valhalla etc forget it! You would need to lower settings and need a 5.2ghz Ryzen 5000 and a 3090 minimum! And i bet you still only get 100. Its massivly GPU limited.

I manage it on a few games, 4770k 2080ti but typically only keep AF 16x and the textures at max and sacrifice everything else. So i play things i can achieve it on and wait on those i cannot. But i think you reslly need the next gen Nvidia 2021 cards tbh a 3090ti would be a real 4k/120 card in my opinion.

Well the 6900XT and AMD might be a solution to that problem.

Doubtful, It will match the 3080? Thats not enough power for this gen at all older games yes but not 2020 games.

I think that’s the 6800XT. We’ll have wait and see, but a 6900XT plus infinity cache and a tweaked Ryzen 3 chip looks set to be the fastest gaming system.

 

[b0rn2sk8]

No, a 6900XT trades blows with a 3090 with rage mode on (small overclock) and SAM, this also hasn’t been independently verified and is only the manufactures data. Trades blows is not better, though the 6900 is cheaper of course.

The 3090 also doesn’t need to be paired with the latest processor to get that performance and at 120fps you can get away with a much older and cheaper CPU to get the same performance.

Once you start overclocking the 3090 to match the rage mode as well it will start to pull ahead again.

If a 3090 can’t do 4K 120 in the latest games at max settings, neither can a 3900XT without sacrificing quality.

If you drop down the image quality you can get 4K 120. That’s what the consoles do.

And before you say doom eternal, yes you could do 4K 120 in that game but it’s just one extremely well optimised game, the vast majority do not run like that.

Don’t get me wrong the 6900/6800 range look like really powerful cards and seriously good value but let’s step off the hype train, take a breath and wait for the claims to be independently verified.
