Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 4870 1GB
IntroThe GeForce GTX 260 Core 216 comes with a core clock frequency of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also features a 448-bit memory bus, and uses a 65 nm design. It is made up of 216 SPUs, 72 TAUs, and 28 Raster Operation Units.Compare those specifications to the Radeon HD 4870 1GB, which features core clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4870 1GB should theoretically be a bit better than the GeForce GTX 260 Core 216 overall. (explain)
Texel RateThe GeForce GTX 260 Core 216 should be quite a bit (more or less 38%) better at AF than the Radeon HD 4870 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 260 Core 216 is the winner, and very much so. (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 (in units of MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 reach the maximum fill rate.
