Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GT 440 1.5GB uses a 40 nm design. nVidia has set the core speed at 594 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 144 SPUs as well as 24 TAUs and 24 ROPs.
Compare those specs to the Radeon HD 6570 (OEM) 1GB, which features GPU clock speed of 650 MHz, and 1024 MB of GDDR3 memory running at 900 MHz through a 128-bit bus. It also is comprised of 480 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GT 440 1.5GB should perform much faster than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB should be a little bit (more or less 9%) better at AF than the GeForce GT 440 1.5GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 440 1.5GB is the winner, by a large margin. (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 max amount of information (counted in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher 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 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 amount of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
