CPU bottleneck neck

[Athomas822]

I have an AMD FX 8370 CPU and I want to upgrade my GPU to the gtx 1080. I was wondering if the 8370 would be a bottle neck for the 1070

[Canada EH]

Yes it will

Your question also depends on what resolution you plan to play with. For most cases, an 8370 should not be a bottle neck for the 1070. If you overclock it, it definitely wont be a bottleneck even for the 1080.

This is wrong.  Even the 6600k is a bottleneck for a 1070/980ti at 1080p in cpu intensive games.   It will most certainly bottleneck a 1080.   Only at higher resolutuons, 1440p and above, where the load shifts to the gpu, does an 8370 not bottleneck high end cards, and generally not untill 4k Do you completely put the onus on the gpu.

 

 

Op, yes, and 8370 will bottleneck a 1070.  That doesn't mean you shouldn't get it, however.  You can always downsample your resolution and run 1440p or 4k on a 1080p display.  Yes, fps will go down, but you won't get large frame time stuttering that occurs with high frame rates/cpu bottlenecks.

FX CPUs also work very well with DX12.

Yup, for all 3 titles.

 

 

Dx 12 does remove cpu overhead, allowing the gpus to do more of the work, but that doesn't make the gpu perform any better, it just lets (radeon) gpus use more of their potential that was starved in dx11.  It really has to do with the gpu driver improvement.  Unless you mean spreading the load over more cores.

I have clearly mentioned it also depends on what resolution OP will play at alongwith the fact that for MOST gaming scenarios it wont bottleneck the 1070 since it has an equivalent performance of an i5 (though shitty IPC but an overclock can help overcome it )

 

The i5 6600k definetly isnt a bottleneck for most gaming related tasks for the 1070, infact an i5 + a 1070 or an i5 + a 1080 is what most people are buying nowadays and is recommended too. Only if OP plans to do some other CPU intensive stuff would there be a bottleneck involved. For a normal gamer, it isnt gonna be worth to go higher than an i5.

 

I would suggest the OP to get a good cooler and OC your current CPU and you will be good with most of your tasks with a 1070

MOST gaming scenarios are at 1080p, in which it IS a problem.  PER core performance is not close to a new i5, which is why it Will bottleneck much worse than one.

 

You don't see people recommending i5's with 1080s.  No one I have seen has done so.  Check digital foundry, hardware unboxed, and many others.  The i5 holds the card back in open world titles (cpu intensive),  and the stuttering induced by being a cpu bottleneck is extremely frustrating. Especially when you are paying so much for a component.

 

 

Once again, I didn't say he shouldn't get a 1070, but he asked the question so he obviously wants to be informed as much as possible going in.  If he buys the 1070, and then expects to go play gta 5 on ultra 1080p, he is going to be a little pissed when it starts stuttering all over the place When the frametimes dip like crazy. Same thing in fallout and far cry 4, cities skyline, far cry primal, witcher 3, and other gpu intensive games.  The Only way to reduce the bottleneck (and the stutter) is to turn the resolution up which drops fps, or have a faster cpu (overclock or replace.)

I have the corsair h100i v2 240mm cooler and it's over clocked @4.7ghz  1.46v

Most i'd put with a 8370 is a 1060.  Upgrade to intel or wait to see what Zen offers

Depends on the game, in DX9 games for sure in DX11 maybe in DX12 well probably not...
