GeForce 8800 GTX vs GeForce 9800 GTX+

Intro

The GeForce 8800 GTX comes with clock speeds of 575 MHz on the GPU, and 900 MHz on the 768 MB of GDDR3 RAM. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.

Compare those specifications to the GeForce 9800 GTX+, which features GPU core speed of 738 MHz, and 512 MB of GDDR3 memory set to run at 1100 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 TAUs, and 16 ROPs.

Texel Rate

The GeForce 9800 GTX+ should be a lot (more or less 28%) faster with regards to AF than the GeForce 8800 GTX. (explain)

GeForce 9800 GTX+ 47232 Mtexels/sec
GeForce 8800 GTX 36800 Mtexels/sec
Difference: 10432 (28%)

Pixel Rate

The GeForce 8800 GTX is a bit (more or less 17%) more effective at FSAA than the GeForce 9800 GTX+, and also able to handle higher screen resolutions more effectively. (explain)

GeForce 8800 GTX 13800 Mpixels/sec
GeForce 9800 GTX+ 11808 Mpixels/sec
Difference: 1992 (17%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units 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 in a second.

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