GeForce GTX Titan Black vs Radeon R9 380X

Intro

The GeForce GTX Titan Black has a GPU core clock speed of 889 MHz, and the 6144 MB of GDDR5 RAM runs at 1750 MHz through a 384-bit bus. It also is made up of 2880 Stream Processors, 240 Texture Address Units, and 48 Raster Operation Units.

Compare those specs to the Radeon R9 380X, which uses a 28 nm design. AMD has clocked the core frequency at 970 MHz. The GDDR5 RAM works at a frequency of 1425 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
