GeForce 8800 GTS (G92) vs GeForce 9800 GTX+

Intro

Compare all that to the GeForce 9800 GTX+, which makes use of a 55 nm design. nVidia has clocked the core speed at 738 MHz. The GDDR3 memory works at a speed of 1100 MHz on this specific card. It features 128 SPUs along with 64 TAUs and 16 ROPs.

GeForce 9800 GTX+		70400 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 8320 (13%)

Texel Rate

The GeForce 9800 GTX+ is a bit (approximately 14%) more effective at anisotropic filtering than the GeForce 8800 GTS (G92). (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 5632 (14%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9800 GTX+ is the winner, but only just. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 1408 (14%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
