Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 5570
IntroThe GeForce GT 440 3GB uses a 40 nm design. nVidia has clocked the core frequency at 594 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this card. It features 144 SPUs along with 24 TAUs and 24 ROPs.
Compare those specs to the Radeon HD 5570, which uses a 40 nm design. AMD has clocked the core speed at 650 MHz. The DDR3 RAM works at a speed of 900 MHz on this card. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GT 440 3GB should be much faster than the Radeon HD 5570 overall. (explain)
Texel RateThe GeForce GT 440 3GB will be just a bit (approximately 10%) more effective at anisotropic filtering than the Radeon HD 5570. (explain)
Pixel RateThe GeForce GT 440 3GB will be much (about 174%) faster with regards to full screen anti-aliasing than the Radeon HD 5570, and will be able to handle higher 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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 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 AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
