Will my CPU bottleneck a GTX 1070

Slaayr · Aug 30, 2016

I've asked this in 2 reddits already, but no one gave me the anwser i want.

I have a i5 3350p, and bought a Gigabyte GTX 1070 G1 Gaming, for a sweet price, where in my country.

Im worried that my CPU will hold my 1070 too much.

The games that i play/will play are: Overwatch, Battlefield 1, Forza Horizon 3, League Of Legends

wouldn't worry too much
it might hold you back a little at certain points but it's not too much of an issue
kinda depends on the display you're using as well.

Im using 2 1080p monitors, only gaming in one

at 60fps you will be more than fine, but going up higher then your CPU will cause bottlenecks

Well thats some good news, because im hyped to install the GPU, but i was very worried about a massive bottleneck or something like that

No massive bottleneck.

Im hoping! Thanks

Not massive, and for most games it is quite small.

You'll probably see up to 25% loss for a few games compared to an i7-6700K, but you'll still have a great experience.

Here's a worst-case scenario with the poorly optimized, older (most is) Fallout 4 engine:

You'd sit around 60FPS for the same 1440p scenario shown. (39/33x 71FPS). Close to 85FPS is possible with better CPU.

Here is a TOMB RAIDER game that has much less CPU load:

Minimal CPU bottleneck here for Tomb Raider.

So..

*So simply forget about it IMO, and tweak the game settings to get your desired FPS. The best benefit requires you understand how to use:
- VSYNC, Adaptive VSYNC, or
- Fast Sync, or
- GSYNC (with GSYNC monitor)

For example, LoL is probably best played using Fast Sync. Some games are best using Adaptive VSYNC.

FastSync
- must be able to output at least 2x the refresh (at least 120FPS for 60Hz monitor)
- no screen tearing
- draws new frames as quick as possible, but only updates monitor with newest one
- *so no screen tear, and reduced lag

Adaptive VSYNC
- turns VSYNC on and off automatically
- you get STUTTER with normal VSYNC if you can't output at least 60FPS (for 60Hz monitor). Disabling VSYNC just gives screen tear like normal. (usually, periodic tear is preferable to stutter)

Holy... thats a complete anwser! Thank you very much!
I will try to forget about it and enjoy the amazing GPU the 1070 is
