GeForce GTX 590 vs GeForce GTX Titan Black

Intro

The GeForce GTX 590 uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory works at a speed of 855 MHz on this specific card. It features 512 SPUs along with 64 TAUs and 48 Rasterization Operator Units.

Compare all that to the GeForce GTX Titan Black, which has a core clock speed of 889 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It features 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could 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 Render Output Units 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
