Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs Radeon HD 4870 1GB
IntroThe GeForce GTX 260 216SP 55 nm comes with a clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit bus, and makes use of a 55 nm design. It features 216 SPUs, 72 TAUs, and 28 ROPs.Compare those specs to the Radeon HD 4870 1GB, which comes with a GPU core clock speed of 750 MHz, and 1024 MB of GDDR5 RAM set to run at 900 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4870 1GB should theoretically perform just a bit faster than the GeForce GTX 260 216SP 55 nm overall. (explain)
Texel RateThe GeForce GTX 260 216SP 55 nm is a lot (more or less 38%) faster with regards to AF than the Radeon HD 4870 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 260 216SP 55 nm is superior to the Radeon HD 4870 1GB, by far. (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 max amount of data (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If 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 number of texture map elements (texels) that are processed in one second. This is calculated 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 in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few 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.
