GeForce 8800 GTS (G80) 320MB vs GeForce GT 240 GDDR5
Intro
The GeForce 8800 GTS (G80) 320MB uses a 90 nm design. nVidia has set the core frequency at 513 MHz. The GDDR3 memory runs at a speed of 792 MHz on this model. It features 96 SPUs as well as 48 TAUs and 20 ROPs.Compare those specs to the GeForce GT 240 GDDR5, which comes with GPU clock speed of 550 MHz, and 512 MB of GDDR5 RAM set to run at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

One Response to “GeForce 8800 GTS (G80) 320MB vs GeForce GT 240 GDDR5”[...] because you rarely find benchmarks 2 series apart. so treat the 9600gt as the 8800gts 320mb. http://www.hwcompare.com/958/geforce...-gt-240-gddr5/ As I said earlier, 260 is just a bit faster than 8800, but also gives way better TDP and DirectX [...]
