r5 3600 bottlenecking a 1070ti?

1 : Anonymous2021/07/30 16:10 ID: ounm21

when i searched for a good cpu for my 1070ti. the answer that always comes up is the ryzen 5 1600, qualifiying it as "the perfect cpu for that gpu". but when i play games with that configuration, my gpu usage is only at 60%. this means that there could be a cpu bottleneck.

should i maybe overclock the cpu? or even changing it completely?

What are you using? R5 3600 or 1600?

I think your title is confusing replies.

Why did you put 3600 in the title - are you looking to upgrade to that?

A 1600 is most definitely a bottleneck in CPU intensive games. Even my 3600 throttles my RX 6800 XT in CPU intensive scenarios and my fps can drop below 60. This happens in games such as Star Wars Jedi: Fallen Order, Batman Arkham Knight, Grand Theft Auto V, Far Cry 3/4/5 in the big villages with many objects and NPCs on screen and Rise of the Tomb Raider. (Reminder that I am talking about max settings in all of these)

I'll also assume from what I've seen from benchmarks online that a 3600 would also drop below 60 in Assassin's Creed Odyssey, Red Dead Redemption 2 and basically most games that have big open worlds with many NPCs, high draw distance and lots of geometry on screen.

I'd recommend a Ryzen 5600 for a better chance at maintaining 60 in your worst case scenarios and 1 percentage lows.

What Ram are you running?

ID: h73kco6

16g ddr4 2400mhz in dual channel

Oh wow that's slow for ryzen.

There's your bottleneck

Just overclock it!

Consider getting 3600MHz CL16 Memory

Ryzens are EXTREMEMLY sensitive to RAM speed. 2400 is just too low. You should be looking upwards of 3600MHz. In Intel processors RAM speed is important but not as much, meaning in the equivalent setup you will lose about 2 frames while in the Ryzen you can lose upwards of 10

1080p in some games? Yeah it could happen. It's not really a bottleneck. It's down to poor optimization and distribution between your CPU and your GPU. The 1070ti is capable of doing 1440p in many games and that will limit the bottleneck even more.

No bottleneck there, i have r5 3600x and RTX 2060 super and no bottleneck here, so you are good... Which games give you that usage? What drivers for gpu you have? What windows?

Im playing Orcs Must Die 3 and i have vsync on so gpu is like 50% all the time, because when i turn off vsync it goes above 100fps for 100% gpu usage,maybe that's the case with you...

Are you getting lower FPS than you'd like?

depends on the game really,

some games use heavy graphics effects and the GPU is slower than the speed the CPU can send Draw calls while also running the game

some other games are less GPU intensive and the GPU pipeline is waiting for more CPU calls

Zen 1 wasnt great in games compared to other CPUs from 2017 and more modern ones, the memory/interconnect system on Zen1 is pretty slow (high mem latency, and high ccx to ccx latency) so the cores always spend a lot of clock cycles waiting for Data to arrive, and the "low" clock speed wall of 3.8 - 4GHz make it even more of a problem

change your CPU if you are not happy with the performance you get now, yeah your 1070ti may not be used to 100% in every game, but it consumes less power and its cooler at the same time so if the FPS is already higher than your monitor refresh rate its not a bad thing really

Nah, even my 3060 ti paired with 3600, maxed out on cyberpunk on 1080p.
