Geforce GTX 760 vs Geforce GTX 770

Intro

The Geforce GTX 760 has a GPU core clock 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 all that to the Geforce GTX 770, which comes with a clock frequency of 1046 MHz and a GDDR5 memory frequency of 1753 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It features 1536 SPUs, 128 TAUs, and 32 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
