Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 4850 2GB
IntroThe GeForce GT 240 GDDR5 1GB features a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It features 96 SPUs, 32 TAUs, and 8 ROPs.Compare all of that to the Radeon HD 4850 2GB, which has core clock speeds of 625 MHz on the GPU, and 993 MHz on the 2048 MB of GDDR4 RAM. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4850 2GB is 17% faster than the GeForce GT 240 GDDR5 1GB in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 4850 2GB will be a lot (more or less 42%) better at anisotropic filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 4850 2GB 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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total 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 processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
