3Digest: 3D accelerators usability and prospect rating calculations for the end of the month
|
Usability ratings are calculated by the following formula:
Kuse = (K-no-AAA * K-with-AAA) ^ 0.7 * (Poss ^ 0.3)) / (Price )) * 200
where:
K-no-AAA - considers performance without AA+aniso.
- For GeForce 6600-6800, RADEON X700PRO-X800XL the following method is used:
K-no-AAA = ((((C10xp^0.6 * C12xp^0.3 * C16xp^0.1) *

- For GeForce 6200, RADEON X300-X600PRO the following method is used:

K-with-AAA - considers performance with AA+aniso. Calculated using the same formula considering AA+aniso performance values.
The similar calculation (but for 1600x1200 resolution only) indicates the prospect of a videocard. The formula contains the same indexes as those used for usability rating calculations, but accelerator's price isn't considered. So, this rating indicates the capabilities of the current 3D cards in the current applications and future games.
You can also compare two ratings to see the correspondence of product prices to their capabilities and features.
Legend:
- Kuse - usability rating. The higher it is, the better card's mark is.
- Kpro - prospect rating. The higher it is, the better card's mark is.

- Price - card price for the end of the month taken from price lists of a number of companies (for an average card);
- Poss - estimated functional potential and quality of a videocard (see remarks below);
Poss is calculated by the following formula:
Poss = (Driver * AF * TLF * DOT3 * EMBM * CEM * AA * S3TC * VS * PS * 3dc * DH) ^ (1/11)
Where:
- Driver - estimated drivers quality (including installation difficulties, etc.) on the 1000-mark scale.
- AF - anisotropic filtering:
- = 700 - available;
- = 0 - n/a;
- TLF - trilinear filtering:
- = 600 - available;
- = 200 - potentially available with resource losses;
- = 150 - approximation;
- = 0 - n/a;
- DOT3 - Bump Mapping DOT3:
- = 600 - available;
- = 0 - n/a;
- EMBM - Bump Mapping EMBM:
- = 600 - available;
- = 0 - n/a;
- CEM - Cubic Environment Mapping:
- = 600 - available;
- = 0 - n/a;
- AA - antialiasing (on condition of minimal gameplay):
- = 700 - MSAA;
- = 1000 - MSAA+SSAA;
- = 1200 - MSAA+SSAA+TAA;
- = 0 - n/a;
- S3TC - texture compression:
- = 1000 - RADEON X700/800 - 3Dc;
- = 600 - RADEON 9600/9700/9800/X800, GeForce FX/6800;
- = 0 - n/a;
- VS - hardware vertex shaders:
- = 1200 - version 3.0;
- = 1000 - version 2.0b;
- = 600 - version 2.0;
- = 0 - n/a;
- PS - hardware pixel shaders:
- = 1200 - version 3.0;
- = 1000 - version 2.0b;
- = 600 - version 2.0;
- = 0 - n/a;
- DH - additional features: dual-monitor output with the support of DualHead/TwinView/HydraVision technologies, TV-tuner, etc.:
- = 700 - RADEON 9600/9700/9800/X800, GeForce FX/6800;
- = 0 - n/a;
P.S. We understand that such way of making ratings is not perfect, therefore we await suggestions and comments from our readers to be considered in our next 3Digest.
