GeForce GTX 980M vs Radeon HD 6870

Intro

The GeForce GTX 980M comes with a GPU clock speed of 1038 MHz, and the 4096 MB of GDDR5 memory runs at 1000 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 96 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon HD 6870, which features a clock speed of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also uses a 256-bit bus, and makes use of a 40 nm design. It is made up of 1120 SPUs, 56 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure 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 graphics 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 amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
