Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 4770
IntroThe GeForce GT 240 GDDR5 makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory works at a speed of 850 MHz on this model. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.Compare that to the Radeon HD 4770, which has a clock speed of 750 MHz and a GDDR5 memory speed of 800 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 240 GDDR5 should in theory be a small bit superior to the Radeon HD 4770 overall. (explain)
Texel RateThe Radeon HD 4770 should be much (approximately 36%) better at texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 4770 should be a lot (more or less 173%) faster with regards to AA than the GeForce GT 240 GDDR5, and also will be able to handle higher screen resolutions more effectively. (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 information (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number 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 a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
