GeForce GTX 650 Ti 2GB vs GeForce GTX Titan Black

Intro

The GeForce GTX 650 Ti 2GB comes with a core clock frequency of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 768 SPUs, 64 TAUs, and 16 ROPs.

Compare all of that to the GeForce GTX Titan Black, which uses a 28 nm design. nVidia has clocked the core frequency at 889 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this card. It features 2880 SPUs along with 240 TAUs and 48 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high 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 texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
