Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 4850 2GB
IntroThe GeForce GTX 470 makes use of a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 RAM runs at a frequency of 837 MHz on this specific model. It features 448 SPUs as well as 56 Texture Address Units and 40 ROPs.Compare those specs to the Radeon HD 4850 2GB, which uses a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR4 memory works at a speed of 993 MHz on this particular card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 470 will be 111% faster than the Radeon HD 4850 2GB overall, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 470 will be quite a bit (approximately 36%) faster with regards to texture filtering than the Radeon HD 4850 2GB. (explain)
Pixel RateThe GeForce GTX 470 should be much (approximately 143%) more effective at AA than the Radeon HD 4850 2GB, and also will be capable of handling higher resolutions without losing too much performance. (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 max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 number of pixels the graphics card could possibly write 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 clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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.
