Compare any two graphics cards:
GeForce 8800 Ultra vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce 8800 Ultra makes use of a 90 nm design. nVidia has clocked the core frequency at 612 MHz. The GDDR3 RAM is set to run at a speed of 1080 MHz on this particular card. It features 128 SPUs as well as 64 TAUs and 24 ROPs.Compare those specifications to the Radeon HD 6570 (OEM) 1GB, which has a clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 Ultra should in theory be quite a bit better than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe GeForce 8800 Ultra should be a lot (about 151%) more effective at texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe GeForce 8800 Ultra is much (approximately 182%) more effective at full screen anti-aliasing than the Radeon HD 6570 (OEM) 1GB, and also will be capable of handling 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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If 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 applied in one second. This number is worked out by multiplying the total amount of 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 processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
