Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 5570
IntroThe GeForce GT 440 3GB comes with a core clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It features 144 SPUs, 24 Texture Address Units, and 24 ROPs.
Compare all of that to the Radeon HD 5570, which comes with core clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 RAM. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GT 440 3GB should be quite a bit faster than the Radeon HD 5570 in general. (explain)
Texel RateThe GeForce GT 440 3GB will be a little bit (approximately 10%) better at anisotropic filtering than the Radeon HD 5570. (explain)
Pixel RateThe GeForce GT 440 3GB should be quite a bit (approximately 174%) more effective at full screen anti-aliasing than the Radeon HD 5570, and also capable of handling higher screen resolutions better. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once 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 AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
