GeForce 9800 GTX vs GeForce GTX 965M

Intro

The GeForce 9800 GTX uses a 65 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR3 RAM works at a speed of 1100 MHz on this particular model. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.

Compare all that to the GeForce GTX 965M, which has a clock frequency of 944 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
