GeForce GTX 650 Ti vs GeForce GTX 750

Intro

The GeForce GTX 650 Ti makes use of a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 memory runs at a frequency of 1350 MHz on this specific model. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Compare all of that to the GeForce GTX 750, which features a clock speed of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
