VS

GeForce 8600 GS (OEM) vs GeForce GTX 965M

Intro

The GeForce 8600 GS (OEM) features a GPU clock speed of 540 MHz, and the 256 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specifications to the GeForce GTX 965M, which makes use of a 28 nm design. nVidia has set the core speed at 944 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this card. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
