As soon as we got the PowerColor’s HD 4870, the luxury design attracted us: 4+2 phase digital powering, new cooler from ZeroThermal, higher clock than a reference 4870, but the price stay as low as a reference card. So we can’t wait to try it out.
After one day’s test, we found the card delivers a gorgeous performance, but lower stability. For one thing, BIOS limited fan speed too low, that results in a higher GPU temperature; For the other thing, it gets through 3DMark Vantage, but fails to complete FurMark test. We believe it’s the BIOS setting that causes these problems and asked PowerColor for a new BIOS, but the answer was not avalaible yet.
In any case, the PowerColor’s HD 4870 surprises us with its elaborate design. We’re expecting PowerColor to release a refine BIOS to make it better than the best.
