Compare any two graphics cards:
Geforce GTX 680 vs Geforce GTX 770
IntroThe Geforce GTX 680 has a GPU core speed of 1006 MHz, and the 2048 MB of GDDR5 memory runs at 1502 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 TAUs, and 32 Raster Operation Units.
Compare all of that to the Geforce GTX 770, which comes with a GPU core clock speed of 1046 MHz, and 2048 MB of GDDR5 RAM set to run at 1753 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 770, in theory, should perform just a bit faster than the Geforce GTX 680 overall. (explain)
Texel RateThe Geforce GTX 770 is a small bit (more or less 4%) more effective at AF than the Geforce GTX 680. (explain)
Pixel RateThe Geforce GTX 770 will be a bit (approximately 4%) faster with regards to full screen anti-aliasing than the Geforce GTX 680, and capable of handling higher screen resolutions while still performing well. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate 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 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 get to the max fill rate.
