GeForce GTX 750 vs Geforce GTX 770

Intro

The GeForce GTX 750 comes with core speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Compare those specifications to the Geforce GTX 770, which features GPU core speed of 1046 MHz, and 2048 MB of GDDR5 RAM running at 1753 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

In theory, the Geforce GTX 770 should be 180% faster than the GeForce GTX 750 in general, because of its greater data rate. (explain)

Geforce GTX 770 224384 MB/sec
GeForce GTX 750 80000 MB/sec
Difference: 144384 (180%)

Texel Rate

The Geforce GTX 770 will be quite a bit (more or less 310%) better at anisotropic filtering than the GeForce GTX 750. (explain)

Geforce GTX 770 133888 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 101248 (310%)

Pixel Rate

The Geforce GTX 770 should be much (about 105%) more effective at FSAA than the GeForce GTX 750, and capable of handling higher resolutions more effectively. (explain)

Geforce GTX 770 33472 Mpixels/sec
GeForce GTX 750 16320 Mpixels/sec
Difference: 17152 (105%)

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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
