Today thanks to PowerColor we have the opportunity to test one of AMD's newest GPU's - The Radeon HD 3850. This version is not a stock HD 3850 card. The card we received from PowerColor is their Xtreme edition with 512MB of GDDR3. The Xtreme edition is a factory-overclocked card, equipped with a ZEROtherm VGA Cooler to offer better cooling performance. The reference Radeon HD 3850 card has 320 stream processors; the core is clocked at 670 MHz and has 256MB of GDDR3 memory clocked at 1.66 GHz. The PowerColor Radeon HD 3850 Xtreme's core is clocked at 720 MHz and has 512MB GDDR3 memory clocked at 1.8 GHz.
