Geforce GTX 760 vs Geforce GTX 770

Intro

The Geforce GTX 760 comes with a clock frequency of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Geforce GTX 770, which comes with a GPU core clock speed of 1046 MHz, and 2048 MB of GDDR5 memory set to run at 1753 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Geforce GTX 760 94080 Mtexels/sec
Difference: 39808 (42%)

Pixel Rate

The Geforce GTX 770 is a small bit (approximately 7%) better at anti-aliasing than the Geforce GTX 760, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Geforce GTX 770 33472 Mpixels/sec
Geforce GTX 760 31360 Mpixels/sec
Difference: 2112 (7%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
