GeForce GTX Titan Black vs Radeon HD 3850 512MB

Intro

The GeForce GTX Titan Black uses a 28 nm design. nVidia has set the core frequency at 889 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this particular card. It features 2880 SPUs along with 240 TAUs and 48 ROPs.

Compare all that to the Radeon HD 3850 512MB, which has a core clock speed of 668 MHz and a GDDR3 memory frequency of 828 MHz. It also features a 256-bit bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
