GeForce 9800 GTX vs GeForce GTX 560 Ti

Intro

Compare all that to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 memory works at a frequency of 1002 MHz on this specific model. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GTX		140 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 30 Watts (21%)

Memory Bandwidth

In theory, the GeForce GTX 560 Ti will be 82% quicker than the GeForce 9800 GTX in general, due to its higher data rate. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce 9800 GTX		70400 MB/sec
	Difference: 57856 (82%)

Texel Rate

The GeForce GTX 560 Ti should be quite a bit (approximately 22%) better at anisotropic filtering than the GeForce 9800 GTX. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce 9800 GTX		43200 Mtexels/sec
	Difference: 9408 (22%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti is superior to the GeForce 9800 GTX, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 15504 (144%)

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 largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
