GeForce 9800 GTX vs GeForce GTX 860M

Intro

The GeForce 9800 GTX has a clock speed of 675 MHz and a GDDR3 memory speed of 1100 MHz. It also features a 256-bit memory bus, and makes use of a 65 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the GeForce GTX 860M, which features a GPU core clock speed of 797 MHz, and 4096 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 1152 SPUs, 96 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the 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 number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
