Tests with Integrated Graphics

The new ATI Radeon HD 4290 graphics core based on the AMD 890GX chipset is claimed to be 12 to 13% faster in games than the graphics core integrated into the AMD 785G chipset. This could be expected since the AMD 890GX-based mainboards have a higher GPU frequency and a Sideport memory chip. 

We are more interested to check out the power efficiency of the new graphics core. 

The comparison of the Gigabyte cards suggests that the Radeon HD 4290 is not much more economical than its predecessor. No wonder as the AMD 890GX North Bridge is manufactured on the same 55nm tech process as the AMD 785G and has a TDP of 22 watts as compared to the predecessor's 15 watts. On the other hand, the ASUS M4A89GTD PRO/USB3 surprises us with its low practical power consumption again, but it is not due to the properties of the chipset. The good results are due to ingenious engineering solutions of ASUS's development team.
