Compare any two graphics cards:
Geforce GTX 760 vs Geforce GTX 770
IntroThe Geforce GTX 760 comes with clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1152 SPUs along with 96 TAUs and 32 ROPs.
Compare all that to the Geforce GTX 770, which has clock speeds of 1046 MHz on the GPU, and 1753 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Geforce GTX 770 should theoretically be just a bit superior to the Geforce GTX 760 overall. (explain)
Texel RateThe Geforce GTX 770 should be quite a bit (more or less 42%) faster with regards to AF than the Geforce GTX 760. (explain)
Pixel RateThe Geforce GTX 770 will be a small bit (about 7%) better at anti-aliasing than the Geforce GTX 760, and also able to handle higher 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 max amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied 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 graphics 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 maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
