Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 4750
IntroThe GeForce GT 430 uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this card. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.Compare all of that to the Radeon HD 4750, which has a core clock frequency of 730 MHz and a GDDR5 memory speed of 800 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is comprised of 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4750, in theory, should perform a lot faster than the GeForce GT 430 overall. (explain)
Texel RateThe Radeon HD 4750 should be a lot (approximately 109%) more effective at texture filtering than the GeForce GT 430. (explain)
Pixel RateThe Radeon HD 4750 is a lot (more or less 317%) more effective at anti-aliasing than the GeForce GT 430, and also able to handle higher screen resolutions while still performing well. (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 max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 are processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
