GeForce GTX 980M vs Radeon HD 6790

Intro

The GeForce GTX 980M makes use of a 28 nm design. nVidia has clocked the core frequency at 1038 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular card. It features 1536 SPUs as well as 96 Texture Address Units and 64 ROPs.

Compare those specs to the Radeon HD 6790, which uses a 40 nm design. AMD has set the core frequency at 840 MHz. The GDDR5 RAM works at a frequency of 1050 MHz on this particular card. It features 800 SPUs along with 40 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
