GeForce GTX Titan vs Radeon HD 5870

Intro

The GeForce GTX Titan makes use of a 28 nm design. nVidia has set the core frequency at 837 MHz. The GDDR5 RAM runs at a speed of 1502 MHz on this model. It features 2688 SPUs along with 224 TAUs and 48 ROPs.

Compare those specifications to the Radeon HD 5870, which makes use of a 40 nm design. ATi has set the core frequency at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this model. It features 1600(320x5) SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
