GeForce 9800 GTX+ vs GeForce GTX 560 Ti

Intro

Compare all that to the GeForce GTX 560 Ti, which comes with a GPU core clock speed of 822 MHz, and 1024 MB of GDDR5 memory running at 1002 MHz through a 256-bit bus. It also is made up of 384 SPUs, 64 TAUs, and 32 Raster Operation Units.

GeForce 9800 GTX+		145 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 25 Watts (17%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti should be 82% faster than the GeForce 9800 GTX+ in general, due to its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 560 Ti is a bit (approximately 11%) faster with regards to texture filtering than the GeForce 9800 GTX+. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce 9800 GTX+		47232 Mtexels/sec
	Difference: 5376 (11%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 Ti is the winner, by a large margin. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 14496 (123%)

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 data (in units of MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, 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 that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
