AMD ever designed HD 4870 X2 back in last August, which pushed NVIDIA to make GeForce GTX295 in response. Considering HD 4770’s great success, we’re wondering if AMD should make a HD 4770 X2 at this time point.


According to our test, HD 4770 CrossFire brings more than 80% 3D performance improvements, superior to HD 4890 nearly 20%. When loaded by 3D tasks, the CrossFire platform sees about 80-100W power consumption increase compared with single HD 4890, but it still consumes less power than HD 4890 does.
