Summary Diagrams

A comparative diagram with the results of the two GeForce GTS 250 cards with different amounts of memory was meant to be the first in this section, but the test session showed no difference between the 1GB and 2GB versions of GeForce GTS 250. Therefore there is no need to build such a diagram. So, the first diagram will show how faster the new Radeon HD 4890 is in comparison with the Radeon HD 4870 whose performance is considered the baseline.

In the low-quality mode, the Radeon HD 4890 has an average advantage of 6.4% and 10.1% over the Radeon HD 4870 at 1280x960 and 1920x1200, respectively. When FSAA and anisotropic filtering are turned on, the advantage is 9.7% and 10.2%, respectively.

The next diagram compares the GeForce GTX 260 and GeForce GTX 275 with the former card as the baseline.

These two cards differ more than the Radeon HD 4870 and HD 4890. The GeForce GTX 275 is an average 13.3% and 15.1% faster at 1280x960 and 1920x1200, respectively, in the low-quality mode and 15.3% and 14.5% in the high-quality mode.

Then, let’s check out the efficiency of the CrossFireX tandem based on two Radeon HD 4770 512MB cards as compared to a single Radeon HD 4770.

CrossFireX technology works in every game now but the performance growth seems to be limited by the amount of graphics memory which is not enough for modern games at high graphics quality settings.

Additionally, you can view a diagram comparing the Radeon HD 4770 CrossFireX with the Radeon HD 4890 and a diagram comparing the GeForce GTX 275 with the Radeon HD 4890.
