Compare any two graphics cards:
GeForce GT 315 vs Radeon HD 5570
IntroThe GeForce GT 315 uses a 40 nm design. nVidia has clocked the core speed at 625 MHz. The DDR3 memory is set to run at a speed of 790 MHz on this card. It features 48 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specs to the Radeon HD 5570, which makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The DDR3 RAM runs at a speed of 900 MHz on this particular model. It features 400(80x5) SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 5570 will be 14% faster than the GeForce GT 315 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 5570 will be much (approximately 30%) more effective at AF than the GeForce GT 315. (explain)
Pixel RateThe Radeon HD 5570 should be just a bit (about 4%) more effective at full screen anti-aliasing than the GeForce GT 315, and also able to handle higher screen 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per 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 card will be at handling 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 could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
