Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 7870
IntroThe GeForce GTX 260 Core 216 makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory is set to run at a speed of 999 MHz on this specific model. It features 216 SPUs as well as 72 Texture Address Units and 28 ROPs.Compare those specifications to the Radeon HD 7870, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory works at a frequency of 1200 MHz on this specific card. It features 1280 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7870, in theory, should be a lot faster than the GeForce GTX 260 Core 216 overall. (explain)
Texel RateThe Radeon HD 7870 should be much (approximately 93%) better at AF than the GeForce GTX 260 Core 216. (explain)
Pixel RateThe Radeon HD 7870 will be quite a bit (more or less 98%) better at full screen anti-aliasing than the GeForce GTX 260 Core 216, and also should be capable of handling higher screen resolutions better. (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 transferred over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
