Compare any two graphics cards:
GeForce GT 430 1GB vs Radeon HD 4830 1GB
IntroThe GeForce GT 430 1GB uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this specific card. It features 96 SPUs along with 16 TAUs and 4 ROPs.Compare all of that to the Radeon HD 4830 1GB, which has a core clock speed of 575 MHz and a GDDR4 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4830 1GB should be much faster than the GeForce GT 430 1GB overall. (explain)
Texel RateThe Radeon HD 4830 1GB should be quite a bit (approximately 64%) more effective at AF than the GeForce GT 430 1GB. (explain)
Pixel RateThe Radeon HD 4830 1GB will be a lot (approximately 229%) better at FSAA than the GeForce GT 430 1GB, and also capable of handling higher 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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
