GeForce 9800 GT 1GB vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which features core clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

GeForce 9800 GT 1GB		105 Watts
GeForce GTX 560		150 Watts
	Difference: 45 Watts (43%)

Memory Bandwidth

In theory, the GeForce GTX 560 will be 122% faster than the GeForce 9800 GT 1GB overall, due to its greater data rate. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 70528 (122%)

Texel Rate

The GeForce GTX 560 should be quite a bit (approximately 35%) faster with regards to anisotropic filtering than the GeForce 9800 GT 1GB. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 11760 (35%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is superior to the GeForce 9800 GT 1GB, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 16320 (170%)

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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
