Compare any two graphics cards:
GeForce GT 315 vs Radeon HD 3650 512MB
IntroThe GeForce GT 315 has a GPU core speed of 625 MHz, and the 512 MB of DDR3 memory runs at 790 MHz through a 128-bit bus. It also is made up of 48 SPUs, 16 TAUs, and 8 ROPs.Compare those specs to the Radeon HD 3650 512MB, which has a GPU core clock speed of 725 MHz, and 512 MB of GDDR3 RAM set to run at 800 MHz through a 128-bit bus. It also is made up of 120(24x5) Stream Processors, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 3650 512MB should in theory be a bit superior to the GeForce GT 315 overall. (explain)
Texel RateThe GeForce GT 315 will be quite a bit (approximately 72%) faster with regards to texture filtering than the Radeon HD 3650 512MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 315 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 Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the ability to get to the max fill rate.
