Compare any two graphics cards:
Geforce GTX 760 vs Geforce GTX 770
IntroThe Geforce GTX 760 comes with a clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is made up of 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.
Compare those specs to the Geforce GTX 770, which features a clock speed of 1046 MHz and a GDDR5 memory speed of 1753 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It features 1536 SPUs, 128 Texture Address Units, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 770 is 17% quicker than the Geforce GTX 760 overall, because of its higher data rate. (explain)
Texel RateThe Geforce GTX 770 will be quite a bit (about 42%) more effective at anisotropic filtering than the Geforce GTX 760. (explain)
Pixel RateThe Geforce GTX 770 is just a bit (about 7%) better at FSAA than the Geforce GTX 760, and 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.
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 largest amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once 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, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
