Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 6870
IntroThe Geforce GTX 670 makes use of a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this specific card. It features 1344 SPUs along with 112 TAUs and 32 ROPs.
Compare those specs to the Radeon HD 6870, which features core speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 1120 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 670 should theoretically be quite a bit faster than the Radeon HD 6870 in general. (explain)
Texel RateThe Geforce GTX 670 will be a lot (approximately 103%) more effective at AF than the Radeon HD 6870. (explain)
Pixel RateThe Geforce GTX 670 should be a small bit (approximately 2%) faster with regards to full screen anti-aliasing than the Radeon HD 6870, and should be able to handle higher 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, 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 most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
