GeForce 8800 GT 1GB vs GeForce GT 340 1GB

Intro

The GeForce 8800 GT 1GB has a GPU core clock speed of 600 MHz, and the 1024 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also features 112 Stream Processors, 56 TAUs, and 16 ROPs.

Compare that to the GeForce GT 340 1GB, which comes with GPU clock speed of 550 MHz, and 1024 MB of GDDR5 RAM running at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred past 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 RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card 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 amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
