Compare any two graphics cards:
GeForce GT 310 vs Radeon HD 5550
IntroThe GeForce GT 310 has core speeds of 589 MHz on the GPU, and 1000 MHz on the 512 MB of DDR2 RAM. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.Compare those specifications to the Radeon HD 5550, which comes with GPU core speed of 550 MHz, and 512 MB of DDR2 RAM running at 400 MHz through a 128-bit bus. It also is made up of 320(64x5) SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GT 310 will be 25% quicker than the Radeon HD 5550 in general, due to its greater bandwidth. (explain)
Texel RateThe Radeon HD 5550 is quite a bit (more or less 87%) more effective at anisotropic filtering than the GeForce GT 310. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5550 is a better choice, 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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, 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 maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
