At the same CPU clock speed a 3.5 times increase in performance is very impressive - which shows the performance potential of Altivec instructions. Blur 2.00x 0.7 1.4 0.5 0.7 0.6 3.7 pix Gaus. Blur 1.65x 2.6 4. Although 150MHz faster in clock speed, the Athlon trails most systems in this test. The G4 gain was very small in these tests as shown in the table below.
All times are in seconds.
I used the same 'Chapter 7 completed' tutorial scene file from my past reviews . Rendering quality was set to Ray Trace, medium anti-aliasing, shadows on, patch detail low. I didn't change the default QT movie output file options. Infini-D was allocated 40MB of RAM for the tests. OS 9 and its 4 Altivec extensions were used for all G4 tests.
