Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 7870
IntroThe GeForce GTX 470 has a clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also makes use of a 320-bit bus, and uses a 40 nm design. It is comprised of 448 SPUs, 56 Texture Address Units, and 40 ROPs.Compare that to the Radeon HD 7870, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM runs at a speed of 1200 MHz on this specific model. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7870 should theoretically perform just a bit faster than the GeForce GTX 470 in general. (explain)
Texel RateThe Radeon HD 7870 should be a lot (about 135%) faster with regards to AF than the GeForce GTX 470. (explain)
Pixel RateThe Radeon HD 7870 should be quite a bit (approximately 32%) faster with regards to FSAA than the GeForce GTX 470, and also should be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
