PowerColor

We've received many emails from readers asking about the phenomenon known as micro-stuttering and what it means to multi-GPU setups in CrossFire and SLI. After running plenty of benchmarks, we're ready to weigh in on what turns out to be a real issue.

It takes guts to try passively cooling a 127 W graphics processor. PowerColor sells the first Radeon HD 6850 we've seen topped only with a heatsink. Does the triple-slot cooler do its job, or is Barts simply too complex of a GPU to cool like this?

PowerColor’s half-height Radeon HD 5750 launched a quest to build a tiny gaming PC. But things didn't work out the way we planned. We ended up building two half-height machines capable of cranking out playable frame rates, and put them both to the test.

Improvements to performance, acoustics, and bundles can add big value once a reference graphics card is modified by third-party vendors. We compare four modified Radeon HD 6850 1 GB boards to find out which company's additions best suit your gaming needs.

AMD quietly introduced its new Radeon HD 5550 and prepped the Radeon HD 5570 GDDR5 to follow. We examine the performance of these two stealth-launched models to see if they have what it takes to replace a couple of power contenders in the sub-$100 market.
