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 speed at 594 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this specific card. It features 144 SPUs along with 24 TAUs and 24 ROPs.
Compare those specs to the Radeon HD 5570, which has core clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 memory. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GT 440 3GB, in theory, should perform quite a bit faster than the Radeon HD 5570 overall. (explain)
Texel RateThe GeForce GT 440 3GB will be a bit (approximately 10%) faster with regards to AF than the Radeon HD 5570. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 440 3GB is superior to the Radeon HD 5570, and very much so. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
