Video Card Roundup - DVD Quality, Features & Performance - October 2000

Performance Comparison
The overall performance is split into five major sections, blitter, data transfer, MPEG-2 encoding, default and reference decoder performance.
The Blitter and Data transfer tests are mainly dependent on local video memory performance and AGP performance. The MPEG-2 encoding test is almost exclusively dependent on the CPU performance of the system and was thus not included as it didn't really have any purpose in the results. The default decoder performance measures the CPU utilization using the currently installed software decoder while playing back a 3Mbit, 6Mbit and 9Mbit MPEG-2 stream.

For the most part the GeForce2 remains in the lead, and in a few cases the Radeon comes pretty close as well. The biggest disappointment here is the Savage 2000 but then again we've never expected the Savage 2000 to be the best performer in any situation. The two 3dfx cards perform very well in these tests, in some situations even besting the GeForce2.
The Data transfer tests were pretty much dependent on a card and driver's ability to transfer data at a high rate, the Radeon ended up coming out in front in Non-Local to Local memory copies, while the Matrox solutions came ahead in the Local to Non-Local and Video to System memory copies.
