Compare any two graphics cards:
Geforce GTX 760 vs Geforce GTX 770
IntroThe Geforce GTX 760 has a GPU core speed of 980 MHz, and the 2048 MB of GDDR5 memory is set to run at 1502 MHz through a 256-bit bus. It also features 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.
Compare that to the Geforce GTX 770, which has core clock speeds of 1046 MHz on the GPU, and 1753 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 770 should in theory perform a little bit faster than the Geforce GTX 760 in general. (explain)
Texel RateThe Geforce GTX 770 will be a lot (about 42%) better at AF than the Geforce GTX 760. (explain)
Pixel RateIf running with a high resolution is important to you, then the Geforce GTX 770 is a better choice, but only just. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
