GeForce 8800 GTS (G80) 640MB vs GeForce GTS 250 1GB
Intro
The GeForce 8800 GTS (G80) 640MB makes use of a 90 nm design. nVidia has clocked the core frequency at 513 MHz. The GDDR3 memory runs at a frequency of 792 MHz on this particular card. It features 96 SPUs along with 48 Texture Address Units and 20 ROPs.Compare that to the GeForce GTS 250 1GB, which has core speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 memory. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number 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 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 number of pixels the video 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 potential to reach the maximum fill rate.

2 Responses to “GeForce 8800 GTS (G80) 640MB vs GeForce GTS 250 1GB”I like this post n I want to buy the Geforce GTS 250 1GB buh u dont actually show the prizes from amazone at all, u only show prizes on different items altogether. So check on that pls
That's Amazon's fault, nothing I can do about it.
