Performance during Video Playback
To evaluate the performance of our today’s testing participants during the playback of different video formats, we used Windows Media Player 10 with the patch to enable the Direct X Video Acceleration for WMV HD-content . For the test purposes we used the following movies:
- “Magic of Flight” movie in WMV HD format, 1080p
- Movi in DivX format, 640x480
- DVD with “Starship Troopers” movie in PAL format
All RADEON X1000 family members demonstrated identical performance here.
New ATI graphics accelerators proved most efficient during WMV HD file playback: the CPU utilization was only 41% in the most complex scene of the movie, where a huge flock of birds raised up into the sky from the lake surface. The minimal CPU workload in this test was 15%, which is more than twice as good as the results obtained by GeForce 6/7 and RADEON X850 XT Platinum Edition. The average CPU utilization during the test movie playback was 20%-25%, which can surely be called an excellent result. According to the results of this test we can call new RADEON X1000 the best solution for HD content playback.
The playback of a movie in DiVX format was less successful: the new ATI product family showed the highest CPU utilization rates during this test. The minimum CPU workload throughout this test equaled 8%, which is better than the 10%-11% by GeForce 6/7 and worse than 2% by RADEON X850XT Platinum Edition.
As for the playback of a standard DVD disc, the newcomers did real well there, leaving no chances for other testing participants.
Well, as we can see from the results of these few tests, ATI Avivo technology works perfectly well, being especially efficient during HD and DVD content playback. Moreover, the results obtained for the 1080p movie can be even called sensational: there haven’t yet been any graphics solutions out there that would cope so well with a resource-hungry format like that. By the first GeForce 6800 Ultra modifications with disabled video processor, the CPU Utilization level could be as high as 100%. Now this number has dropped down to 20%-30% due to ATI’s Avivo technology. At the same time, the CPU utilization during DivX playback appeared higher than by the competitors, although it is still not too bad to cause you any serious inconvenience. I think that the final CATALYST version for RADEON X1000 may be free from this drawback.
It is remarkable that all RADEON X1000 models demonstrated the same performance during video playback. Looks like the Avivo processor works at its own frequency, which is the same for all members of the new family, and isn’t connected with the GPU clock rate.
