GeForce GTX 280 vs GeForce GTX Titan Black

Intro

The GeForce GTX 280 makes use of a 65 nm design. nVidia has clocked the core frequency at 602 MHz. The GDDR3 memory is set to run at a speed of 1107 MHz on this specific card. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX Titan Black, which features clock speeds of 889 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 RAM. It features 2880 SPUs as well as 240 TAUs and 48 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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