Compare any two graphics cards:
GeForce 9600 GT 1GB vs Radeon HD 6950
IntroThe GeForce 9600 GT 1GB makes use of a 65/55 nm design. nVidia has set the core speed at 650 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this specific card. It features 64 SPUs as well as 32 Texture Address Units and 16 ROPs.
Compare those specifications to the Radeon HD 6950, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this particular card. It features 1408 SPUs along with 88 TAUs and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon HD 6950 should be quite a bit faster than the GeForce 9600 GT 1GB in general. (explain)
Texel RateThe Radeon HD 6950 is a lot (about 238%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)
Pixel RateThe Radeon HD 6950 will be quite a bit (approximately 146%) more effective at FSAA than the GeForce 9600 GT 1GB, and should be capable of handling higher screen resolutions more effectively. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
