The first round out onscreen frame time results shouldn’t come as any surprise for someone familiar with AMD’s struggles in this area. Not all that much has changed, with the HD 7990 providing a wholly unacceptable gaming experience in Assassin’s Creed III, Crysis 3 and Far Cry 3. In each of these instances, the stuttering was extremely noticeable.

Tomb Raider and Max Payne had two more “almost good” results since they only displayed a few instances where the HD 7990 noticeably stuttered. However, in both situations (particularly in Tomb Raider), the GTX 690 provided a noticeably smoother experience.

These results are simply detrimental to AMD’s hopes of laying claim to the title of fastest graphics card in the world. It seems like the HD 7990 is dropping or partially rendering a ton of frames in Crysis 3, Far Cry 3 and even some within some areas of Dirt Showdown. Ironically, in Assassin’s Creed III, it is relatively well behaved.
Compare and contrast the HD 7990 to the numbers posted by the GTX 690 and you’ll find a clear win in favor of NVIDIA. This goes to prove that while the HD 7990 is a fast solution according to FRAPS, a good portion of its rendered frames never make it to the screen, thus eliminating what was a considerable advantage.

But once we take away the runts and drops we find the HD 7970s in CrossFire fall behind the performance of both of the NVIDIA GeForce cards.
