Sapphire Radeon HD 5670 Overclocking just might be futile

There are two tiers of graphics cards out there, those that are worthy of overclocking and those that aren’t. Architecture differences, namely memory bandwidth, are the biggest roadblock to overclocking effectiveness.

TweakTown has a look at how well the Sapphire Radeon HD 5670 handles some increased clock speeds and it’s not looking so hot:

You’re not going to get a game changing experience with the extra clocks on offer and when you look through the graphs you see that the performance increase is only a couple of FPS here and there, which doesn’t sound all that impressive.

If you intend on grabbing a Radeon HD 5670 with some tweaking on your mind you might just want to save up and go for something with a wider memory bus width otherwise appreciate it for what it is as a media accelerating, low-power using, mid-range card.
