GeForce GTX 650 Ti 2GB vs GeForce GTX Titan Black

Intro

The GeForce GTX 650 Ti 2GB uses a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 memory works at a speed of 1350 MHz on this particular card. It features 768 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Compare that to the GeForce GTX Titan Black, which features GPU clock speed of 889 MHz, and 6144 MB of GDDR5 memory set to run at 1750 MHz through a 384-bit bus. It also is made up of 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
