GeForce GTX 650 Ti vs GeForce GTX Titan Black

Intro

The GeForce GTX 650 Ti has a clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

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

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a 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 - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
