GeForce GTX 280 vs GeForce GTX 980M

Intro

The GeForce GTX 280 makes use of a 65 nm design. nVidia has set the core speed at 602 MHz. The GDDR3 memory is set to run at a frequency of 1107 MHz on this model. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 980M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1038 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 1536 SPUs along with 96 Texture Address Units and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
