Does overclocking a gpu boost performance marginally?

Recommended Posts

Posted · Original PosterOP

I always see JayzTwoCents or Slick/Luke overclock their gpus in testing and I would like to know if it actually makes a difference? Gpus usually base at 1ghz, and after that I see people getting them up to 1400 mhz (1.4 ghz) and I am wondering, does it make a difference in gaming performance? I am thinking of building a pc and I probably wont overclock, but I want to know if I do, would it give me a 10% boost? 20% boost? More? Less? The gpu will be the r9 380x, so yeah have at it. The gpus I saw tested were in this video:

Thanks!


Is Firewatch playable on ultra at 11 fps? Yes it is!

Check meh profile for my laptop specs, don't want to scare anyone without warning them

Hmm. Then why do Jay and Luke do it?

depends on how big a overclock you do

Boost was at around 1300, and OC was at 1400

theres no set increase in performace, it varies from card to card and what games you are playing

It all depends on the card being used, how well each card overclock, and if the games was GPU speed limited and not memory, bandwidth or processor limited..

 

Depending on the card you can see significant increases.. Generally though you won't see a 10% difference UNLESS it stops you from chugging a bit or stops Vsync dropping to 30fps or less.

 

It's like you can compare it to performance in other things.. eg a car thats 10 - 20 % faster, you only really see when it's pushed, being timed or racing.. You don't notice the increases for the most part and when you do, generally, you need a side by side comparison, unless as said, it stops issues coming in that the oc can negate.

 

Is it worth doing? well that depends on if it would stop you having an issue, or push frames from a point where it's not as fluid as you'd like to where it is.

being honest, these "gains" those are more visible when doing benchmarks and stuff. irl these boosts are not as visible as shown in these review videos. 

i prefer the life of my stuff more than say, 5% of gain. 

also u know certain games react different to certain configs, so all in all i would not recommend unless, u have shit load of money to upgrade ur broken and burnt hardware :D

Well, it depends on the amount of overclock. It can have a very noticeable increase in performance.

 

Taking my card (1,000 mhz base clock and around 1,200 boost clock) to 1,500 mhz gave a noticeable increase.

 

For example in Fallout 4 ultra settings with max shadow/object/person draw distances at 1440p at stock speeds the framerate tends to drop well below my 85hz vsync cap but when overclocked it tends to stay at(over) the 85hz cap much more.

 

Sorry i cannot give you solid numbers but I just don't have numbers recorded just my observations.

For me, i have the g1 r9 380, stock is 990MHz core, 1425MHz memory. Before the OC i was sometimes dipping into 30-40 fps on GTA V. After my oc, where i got to 1100MHz and 1600MHz memory, I get constant 60 with dips to 55. For me on GTA V it helped alot.

It depends a lot with the gpu and the game played.

As you'll be getting a 380x, better stop thinking about 1400MHz (Maxwell terrain), because the maximum will be 1150-1200MHz.

Then, there're some games that see a nearly 1:1 ratio increase, while other even if you get a 20% OC you barely get 1-2fps more.
