Compare any two graphics cards:
GeForce GT 315 vs Radeon HD 3650 256MB
IntroThe GeForce GT 315 makes use of a 40 nm design. nVidia has clocked the core frequency at 625 MHz. The DDR3 memory works at a speed of 790 MHz on this card. It features 48 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 3650 256MB, which has a core clock frequency of 725 MHz and a DDR2 memory speed of 800 MHz. It also features a 128-bit bus, and uses a 55 nm design. It features 120(24x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 3650 256MB should in theory be a little bit superior to the GeForce GT 315 in general. (explain)
Texel RateThe GeForce GT 315 will be quite a bit (more or less 72%) more effective at anisotropic filtering than the Radeon HD 3650 256MB. (explain)
Pixel RateThe GeForce GT 315 should be much (more or less 72%) better at AA than the Radeon HD 3650 256MB, and able to handle 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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 quite a few 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.
