as you are running it higher than the intented speed of manu, you will have an overall faster system + FPS increase (although this depends case on case)

Your room stays a lot warmer in winter ?

 

All kidding aside, different people will have different opinions as allways.

For most its just a hobby, for some competitive.

 

My take on it its just a few FPS at the cost of a disproportianate amount more power, and thus noise, thus needing more expensive psu, high airflow hovercraft level noise cabinet etc. It is not "free performance", i think a lot of times the expenses could have been better put towards higher tier cpu or gpu (although some exceptions like intel 9900 exist i suppose).

 

And with nvidias recent gpu boost, and AMD cpus being stock already at the edge of what they can do most oc do very little except consume a ton of more power and possibly doing more harm than good.

all you are doing is increasing the amount of cycles the chip completes per second. as result, it's compute performance which is measured in floating point operations per second increases. you are doing more work in the same amount of time

makes it do more work, so you can say that leads to more frame rates, but also more heat

Yeah this is a good analogy.

In general stock car can be tuned to have higher power output.

Is it good? no, it creates problem in the long run like overheating etc.

 

Overclocking in general boost the overall system performance, not just games.

Games happens to be the easiest to quantify.

For the record, I was asking in regards to overclocking GPUs.

Makes the GPU run faster than its stock speed, which should improve FPS. Also usually makes it run hotter and use more power.

 

By how much performance improves depends on how much you overclock its core and/or memory and whether the GPU is now starved for data because the CPU is now too slow to keep it fed. Might also run into the issue that it runs into power limits or the additional heat causes it to throttle a lot if e.g. the cooler isn't good enough.

My GPU overclock is good for about 10 frames and a little more heat. It is not on by default like my CPU overclock and I set it before I play a game. 

 

All my GPU gaming overclocks use the default fan curve to keep noise down but I have benching overclocks that use 100% of the fans. They are really noisy.

 

If I am playing at 4k or RT games I usually notice if I forget to turn on the overclock but at lower resolutions and without RT I may not notice at all.

more fps, more productivity. Nowadays i'm warming up to optimizing voltages even on stock. The stock settings of zen 2 is a bit of a mess, gotta optimize the voltage.

 

For Turing, my card will deliver the same performance on a lower power limit than stock.
