Minimum cpu that won't bottleneck pascal mxms

What would be the minimum for the 1060? And if different what is the minimum for the 1070?

 

Not all engines utilize CPUs the same. Some like more speed, some like more cores and some will use all you got of both.

I've just recently soured on the 6300HQ for a gtx 1060 and see that pairing as a mixed result of good&bad when compared with an i7/1050Ti. The 7300HQ/GTX1060>i7/1050Ti. I don't think the i5 is ever matched to a 1070. The locked i7(s) is plenty fast for the 1060/1070 even if you leave a few fps on the table here and there.

 

Very True

 

For a 1060 - I'd say start at an i7 6700HQ or i7 7700HQ
For a 1070 - it depends - at 1440p or higher, the above-mentioned CPUs are fine. For 1080p - you really want a 6820HK or 7820HK for the higher clockspeed capabilities
For a 1080 - I'd really recommend a 6820HK or 7820HK - As we've seen, 6700HQ bottlenecks it and the 7700HQ is not that much faster. You really want a high end CPU to go with a top end GPU

i5 6300HQ and i5 7300HQ are suited more towards the 1050 and 1050 Ti

 

Thanks Don, I will keep that all in mind.

 

Agreed! My thoughts exactly!

 

6820HK/7820HK at 4.0Ghz, for the 1070. The 3.4Ghz of the 7700HQ will hold the GPU back, at both 1080p and 1440p.

The 1070 isn't fully GPU bound until 4K resolution.

 

Its a complicated question. For almost all games you can adjust your graphics alot more than cpu options. So your cpu determines your max fps in most cases if you are willing to lower graphics settings. If you have a game you have in mind it would be helpfull to lookup or ask what fps it can get in that game. Make sure its up to your standards. The 6700hq can get 144 fps or more in overwatch 99% of the time for example.

I would get a cpu that can do what you want it to do then go from there. The good news is that you can look at your gpu's usage and if its not high enough you can adjust settings up and get a better looking game. If its too high you can adjust down and get more fps. This way you can get your parts to use all their power in most situations.

 

Er what? This is simply not true even if you turn down settings, unless you're by yourself in the Practice Range or something. Remember, the 6700HQ is clocked very low, only 3.1 GHz. It's simply not fast enough for 144Hz gaming.

 

I'm sorry but i own the 6700hq and i get 144 fps or more 99% of the time in overwatch. Please know what you are talking about before you post. If you want to disagree still I'll post a shadowplay of it and put you in your place. I'm tired of people saying things without knowing what they are talking about.

 

Sure go ahead, and your settings while you're at it. I know I can't hold 144 FPS constant in a 6v6 point capture/hold even with a 4790K at 4.5, which wipes the floor with your 6700HQ.

 

I must mention to make sure you are not near 100% gpu usage even though you probably already have done that. If you are near 100% gpu usage ever, turn down your graphics settings.

The cpu waits for the gpu. Overwatch gets around this a little with the multithreaded renderer (one thread does the waiting while others keep working). Turning off vsync can still help. This way the cpu doesnt wait for the gpu while the gpu is waiting for the screen. Nvidia fastsync will have a similar increase in cpu perfromance compared to vsync off. The "reduce buffering" option in game refers to the multithreaded renderer buffering. Turning "reduce buffering" to ON can decrease cpu performance but also reduce input lag. However the input lag change is not as great as with triple buffering. If you are cpu limited I would turn "reduce buffering" to OFF. You should not need to use triple buffering with this game.

If you are super stable at your desired refresh rate and using vsync off you can limit your fps with the in game fps limit to 3 or 4 frames above your monitors refresh rate. This will help with the way that the screen is updated with data making sure that each part of the screen has about the same relationship between cpu/gpu side updates happening each frame.

If you cant maintain the desired refresh rate when using the in game frame limiter then put it at its max 300. This can give you a little wiggle room when having 1 frame computation spikes.

Sorry about the cell phone video but I dont want to set up shadowplay and edit the video right now.
