Compare any two graphics cards:
GeForce GTX 560 vs Geforce GTX 760
IntroThe GeForce GTX 560 comes with a core clock frequency of 810 MHz and a GDDR5 memory speed of 1001 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It features 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.
Compare all that to the Geforce GTX 760, which has a clock frequency 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 comprised of 1152 SPUs, 96 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 760 should be 50% faster than the GeForce GTX 560 in general, because of its higher data rate. (explain)
Texel RateThe Geforce GTX 760 is quite a bit (approximately 107%) faster with regards to texture filtering than the GeForce GTX 560. (explain)
Pixel RateThe Geforce GTX 760 should be quite a bit (approximately 21%) better at full screen anti-aliasing than the GeForce GTX 560, and also will be able to handle higher screen 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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
