What makes a GPU better than the other?

post #1 of 4
Thread Starter 
I've been wondering this ever since I started looking into upgrades. Some cards with the same clock speeds and VRAM can benchmark twice as high as the other one.

I know very little about GPU tech besides the clock speeds and total memory size. What else is there that makes them so much more powerful?

As stated above, lots of other specs are important beside memory and clock speed ... the best thing to do is to look up benchmarks though before you buy. There's too many variables involved to just look at specs ... well, I should say, you'd have to *really* understand the technology and each companies product lines to be able to properly make a buying decision based on specs alone. It's not wise for anyone to do it that way tbh, should always check the online benchies, preferably at a few different sites with different game selections, and pay special attention to the results at the resolution you plan to play with.

You can also always post options/prices here and let the other OCN'ers help ya thumb.gif

Good advice, thanks.
