Compare any two graphics cards:
GeForce GT 315 vs Radeon HD 5570
IntroThe GeForce GT 315 comes with clock speeds of 625 MHz on the GPU, and 790 MHz on the 512 MB of DDR3 memory. It features 48 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 5570, which makes use of a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 RAM works at a speed of 900 MHz on this card. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 5570 should be a bit faster than the GeForce GT 315 in general. (explain)
Texel RateThe Radeon HD 5570 will be much (more or less 30%) better at anisotropic filtering than the GeForce GT 315. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 5570 is the winner, but only just. (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 Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 are applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
