GeForce GTX Titan Black vs Radeon R9 270

Intro

The GeForce GTX Titan Black uses a 28 nm design. nVidia has set the core speed at 889 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this particular model. It features 2880 SPUs along with 240 Texture Address Units and 48 Rasterization Operator Units.

Compare that to the Radeon R9 270, which features a GPU core clock speed of 900 MHz, and 2048 MB of GDDR5 memory running at 1400 MHz through a 256-bit bus. It also features 1280 Stream Processors, 80 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
