Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs Radeon HD 6770
IntroThe GeForce 9500 GT 512MB GDDR3 comes with a clock frequency of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 128-bit memory bus, and uses a 55 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 6770, which has a core clock speed of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 800 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6770 should theoretically perform a lot faster than the GeForce 9500 GT 512MB GDDR3 overall. (explain)
Texel RateThe Radeon HD 6770 is much (approximately 309%) more effective at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateThe Radeon HD 6770 will be quite a bit (about 227%) better at anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and should be able to handle higher screen 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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
