by techPowerUp! (Apr, 2009)To find the maximum overclock of our card we used a combination of ATITool's successor and our benchmarking suite.
by techPowerUp! (Apr, 2009)Many partners will be offering overclocked boards as well ranging up to 1000 MHz core speed.

What People Are Saying Give it to me straight
Performance
by techPowerUp! (Apr, 2009)At 1920 x 1200, performance increments of 92.3%, a near-perfect scaling is observed, which is impressive indeed.
by techPowerUp! (Apr, 2009)8.0PowerColor's HD 4890 PCS can impress with great performance right out of the box.
by techPowerUp! (Jun, 2009)The card offers considerably improved performance over the HD 4890 reference design and can beat the GeForce GTX 280.
Power
by techPowerUp! (Apr, 2009)Two six pin PCI-Express power connectors are required to supply additional power to the graphics card.
by techPowerUp! (Aug, 2009)Power is delivered to the card via two six pin power connectors.
by techPowerUp! (Apr, 2009)This means that any decent power supply should be able to power such a dual HD 4890 rig.
Multi card
by techPowerUp! (Apr, 2009)Once the drivers are up and running, you will be greeted by a message from ATI's Catalyst Control Center, that a CrossFire compatible configuration has been detected and that it would be best if you enabled CrossFire.
by techPowerUp! (Apr, 2009)After installing the cards you need to put both CrossFire bridges across the CF connectors, hook up the power and you are ready to go.
by techPowerUp! (Apr, 2009)It's now 1:46 AM here and I tested the HD 4890 CrossFire setup fan noise.
Applications
by techPowerUp! (Apr, 2009)This is very nice for overclockers because they can now change both voltages via software.
by techPowerUp! (Apr, 2009)Voltage controller does not support software adjustments.
by techPowerUp! (Aug, 2009)At its suggested retail price of US $249, the MSI HD 4890 SOC is a decent buy for its target buyers, gamers looking for peace of mind when it comes to high-definition gaming.
Consumption
by techPowerUp! (Jun, 2009)Overall the power consumption is very reasonable.
by techPowerUp! (Aug, 2009)If you remember the last page, power consumption of this card is really high.
by techPowerUp! (Apr, 2009)In both idle and load the card draws a lot of power, making it the least efficient card in our test group when considering performance per Watt.
