Pixel Shader Performance

Again, using RightMark D3D we'll take a look at some of the Pixel Shader performances of the S18 Nitro alongside the other boards:



Rightmark3D, 1024x768 (FPS) S18 Nitro X600 PRO 6600 6200
PS1.1 Procedural 77.0 98.0 144.3 67.7
PS1.4 Procedural Procedural 84.4 57.6 100.4 52.8
PS2.0 Procedural 48.2 51.1 67.1 32.8
PS2.0 1 Light (FP) 35.1 41.9 66.4 33.3

S18 % Faster Than: X600 PRO 6600 6200
PS1.1 Procedural -21.4% -46.6% 13.7%
PS1.4 Procedural Procedural 46.4% -15.9% 59.7%
PS2.0 Procedural -5.7% -28.1% 47.0%
PS2.0 1 Light (FP) -16.2% -47.1% 5.5%
PS2.0 1 Light (PP) -16.0% -59.0% -17.2%

Given the number of shader pipelines the 6600 has its not much of a surprise that the S18 is performing lower in these shader tests than that, however its also having a hard time against the X600 PRO in a number of cases.

We'll take a look at more shader performances with ShaderMark V2.1:

Under ShaderMark the S18 is having an even more difficult time in relation to the other boards, even underperforming the 6200.
