GeForce 8600 GT 1GB GDDR3 vs GeForce GTX 465

Intro

The GeForce 8600 GT 1GB GDDR3 uses a 80 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 memory is set to run at a frequency of 700 MHz on this specific card. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare those specifications to the GeForce GTX 465, which has a core clock speed of 607 MHz and a GDDR5 memory speed of 802 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It is comprised of 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
