Performance in First-Person 3D Shooters
Aliens vs. Predator
The improve tessellation unit shows good performance. Of course, the new Radeon HD 6800 cards, priced at $179-239, cannot match the GeForce GTX 470 ($259) but the senior model is as good as the GeForce GTX 460 1GB and even beats the latter at 1920x1080 and higher resolutions in terms of bottom speed. We must confess that the gameplay is only comfortable at 1600x900, though. Thanks to the architectural improvements even the Radeon HD 6850 is ahead of the Radeon HD 5870 in this game. And that’s just the beginning.

The results confirm AMD’s promise. Having fewer functional subunits, the Radeon HD 6870 competes with the Radeon HD 5850 successfully, even though this is largely due to the difference in their GPU clock rates. The Radeon HD 6850, on its part, does even better than promised, beating the GeForce GTX 460 768MB and matching the GeForce GTX 460 1GB. Considering its lower price, the Radeon HD 6850 looks most appealing but what will the other tests show us?
Call of Duty: Modern Warfare 2
AMD’s promise to deliver the performance of a Radeon HD 5850 is only fulfilled by the Radeon HD 6870 at 1600x900. Starting from 1920x1080, the new card is somewhat slower than its predecessor. Considering the different price ranges, we doubt anyone would want to exchange his Radeon HD 5850 for a Radeon HD 6850, especially as there are still very few games with tessellation. We can note that the 6800 series can be slower than the 5800 cards, though.
Despite being known as a very heavy 3D application, this game doesn’t use tessellation and the Barts cannot show its best here. As a result, the senior model of the new series is only as good as the Radeon HD 5850 while the junior model competes with the GeForce GTX 460 1GB at high resolutions. This is, however, of little practical worth since the frame rates of these cards are only high enough for normal play at 1600x900.
