GTX 770 Bottleneck?

Postposted on Mon Dec 02, 2013 12:24 am

This is the system I am going to put the GTX 770 in. Will it be bottle necked by the processor etc?

Depends on the game. However, even at stock CPU speed I doubt you'll be seeing much of one unless it's a game that's not very GPU dependent, in which case your FPS will be well beyond 60 anyway...

What is your monitor resolution? 1080p?
Is your processor over clocked?
If you're running at stock on 1080p, I'd say the processor is holding your GPU back slightly, but not a serious bottleneck.

If you are driving 4Megapixels or more. The GTX 770 becomes the bottleneck in newer titles. If you are driving 2Megapixels (1080p and 1920x1200) then the CPU is going to be bottleneck. You will see it mostly in CPU-intensive games like BF4, Civilization 5 (late game), EU4 (late game) and Starcraft 2 (8 player bouts).

It really just depends on what you play. It's impossible to say XYZ CPU is a bottleneck for ABC GPU globally, because sometimes the CPU just doesn't really matter, and other times you'll be CPU-limited no matter what you have.

Case #1: RAGE -- RAGE does not really care what CPU you have, as long as your GPU is fast enough to do the virtual texture decoding. I've seen RAGE played flawlessly at 1440p 60FPS on a Core 2 Duo (stock speed!) and a GTX 580.

Case #2: TERA Online -- TERA does not really care what GPU you have, as long as it's past a certain point of performance. Some friends of mine saw performance improve a lot going from Intel HD 3000 to various Fermi-based Geforce cards, but I saw minimal performance improvement going from SLI 460s to a GTX Titan, so I tested CPUs briefly -- it runs about the same on a Core i3-3220 as it does on my 3570K, but going from 3.4ghz -> 4.4Ghz on my Core i5 made a bit of difference (not much!), and it still bogs pretty hard when you get into it.
As an aside, most MMORPGs exhibit similar performance characteristics as the above, including Everquest II, World of Warcraft, Champions Online, Neverwinter, The Old Republic, Guild Wars 2, and so on.

Case #3: Warframe -- Warframe does not really care what CPU or GPU you have, because it has both 32-bit and 64-bit versions of its DX9 and DX11 renderers, and it's going to run like bollocks in any case. I've seen Warframe played on tons of machines (it's free, after all), and your maximum framerate can be quite high if you have fast hardware, but your minimum framerate -- and average, over a long period -- is going to be no higher than the 30-40 range no matter what you have. I'd like to chalk this one up to the game's "Beta" nature, but it's been "Beta" for over 2 years now and nothing's really changed on this front -- if anything, it's gotten *worse*. The netcode sure has.

You definitely won't be CPU bottlenecked in any game with a single GPU and a 2500k.

You may become slightly CPU bottlenecked if you use multiGPU.

Single GPU (R9 290x) BF4: 4FPS difference between AMD FX-4100 (94fps) and Intel i7-4960x (98FPS) with R9 290X 1200p

Dual GPU (ASUS ARES II) BF4: 128FPS i7 3970x, 58FPS AMD FX-4100, a whopping 70FPS difference.

Last year, I was very CPU bottlenecked with an i5 750 quad core @ 3.06 GHz and 2 GTX 670s in SLI. I was getting 50 FPS with 2 GPUS, and 60 FPS with 1 GPU in BF4.

Overclocking to 4GHz removed most of the bottleneck to the point that I was getting 90-120FPS but still my frame rates were a bit of a rollercoaster. Getting an i7 3820 removed the bottleneck completely and things were subjectively smoother on my 120hz monitor.

I don't think there are many games right now where you will be CPU bottlenecked, unless deliberately imposed by playing at a low resolution like 720p.

Late game CIV 5 maybe..... and busy WOW games could see your performance take a hit but still, the 2500k is no slouch and I'm sure you can OC to 4.4-4.6 GHz with relative ease.

There will always be a bottleneck somewhere and it depends on what game you're playing.

If you run into a situation where the i5-2500K is the bottleneck, I guarantee your FPS will be so high you won't care. And if for some reason you do care (looking for 120FPS?), that CPU overclocks very well. So no worries, you're good.
