Compare any two graphics cards:
GeForce 9600 GT 1GB vs Radeon HD 6950
IntroThe GeForce 9600 GT 1GB comes with core speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 64 SPUs as well as 32 Texture Address Units and 16 ROPs.
Compare those specs to the Radeon HD 6950, which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this specific card. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 6950 should theoretically be a lot faster than the GeForce 9600 GT 1GB overall. (explain)
Texel RateThe Radeon HD 6950 should be a lot (approximately 238%) more effective at AF than the GeForce 9600 GT 1GB. (explain)
Pixel RateThe Radeon HD 6950 should be much (about 146%) more effective at full screen anti-aliasing than the GeForce 9600 GT 1GB, and should be capable of handling higher screen resolutions without losing too much performance. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
