GL Excess

GL Excess is very good tool for measuring the performance of VGA cards on OpenGL applications and games. This benchmark is consisted of 12 scenes grouped in 4 categories (3 scenes in 1 category). Each category stresses different OpenGL graphical sequences. The overall result named XSMark is the sum of the first scene of each category. All scenes were run in the 1024x768 resolution at 32bit.

- Category 1

The first category include scenes 1,9 and 12. Nothing specific is stressed on these scenes. Just average use of general OpenGL techniques.

The pic you see is from scene 12 is made of three shifting and rotating layers, which are textured in 4 blending modes. Nice effect!

Aeolus is behind the ATI cards but it summed up a somewhat equal score as the FX 5900 did.

- Category 2

The scenes 3,5 and 6 stress the card's 3D particle and polygon processing. Particles are widely used in games and you see them for example when you fire with a laser beam or when you light up a torch.

All 3 scenes are made with a particle system that stresses the card's polygon count and video memory. The spaceship you see in the picture is made of a very large number of polygons.

Here the GForce cards show their presence showing their good ability when rendering many polygons.

- Category 3

The third category sum up scenes 4,10 and 11 that render the blending ability of the card. Blending is the mixture of the graphic layers that result in complicated textures and effects.

The fill rate of each card is also stressed in these scenes. So this test should be a reference of the quality of each card.

With a 3.2 Gpixels/sec pixel fill rate, Aeolus FX 5900 XT run off this test with a rather expectable score.

- Category 4

Scenes 2 and 7 that constitute this category have to do with multitexturing effects. Multitexturing is the process of applying two or more textures to a single polygon or pixel, in order to provide spectacular images.

Scene 8 uses a sphere map that is mixed to a simple texturing technique in order to give reflection effects. Just to know, the reflection and shadow effects you see in games are being accumulated by the stencil buffer

Aeolus here shows it's teeth surpassing even the high-toned Radeon 9800 XT.

XS Marks

The XS Marks is the score of the GL Excess benchmark. Keep in mind that this score doesn't sum up the results of all 12 scenes but it sums up the score of each category's first scene. The XSMarks you get with your card can be posted on the GL Excess web site to compare it with other scores.

Not bad are the results Aeolus brought. Staying behind it's ablest rival Radeon 9800 XT with only 600 points difference, resulted a score of 10493. Not bad at all for a GeForce XT card.

Till now the synthetic benchmarks indicated a rather expectable outcome with AOpen Aeolus 5900 XT struggling to catch up with the other. Now let's see if the situation changes with our game benchmark suite.
