Compare any two graphics cards:
Geforce GTX 770 vs Radeon HD 7870
IntroThe Geforce GTX 770 features core clock speeds of 1046 MHz on the GPU, and 1753 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.
Compare those specifications to the Radeon HD 7870, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1200 MHz on this card. It features 1280 SPUs as well as 80 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 770 is 46% quicker than the Radeon HD 7870 in general, because of its higher bandwidth. (explain)
Texel RateThe Geforce GTX 770 should be much (approximately 67%) faster with regards to texture filtering than the Radeon HD 7870. (explain)
Pixel RateThe Geforce GTX 770 is just a bit (more or less 5%) better at full screen anti-aliasing than the Radeon HD 7870, and also should be able to handle higher 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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core 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 applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
