GeForce 8800 GTS (G92) vs GeForce GT 340

Intro

The GeForce 8800 GTS (G92) makes use of a 65 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 RAM is set to run at a frequency of 970 MHz on this specific model. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the GeForce GT 340, which features a GPU core clock speed of 550 MHz, and 512 MB of GDDR5 RAM set to run at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Specifications

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
