GeForce GTX 650 Ti 2GB vs GeForce GTX 750

Intro

The GeForce GTX 650 Ti 2GB comes with a GPU core clock speed of 928 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1350 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 64 Texture Address Units, and 16 ROPs.

Compare all that to the GeForce GTX 750, which comes with a clock frequency of 1020 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
