GeForce GTS 150 vs GeForce GTX 560 Ti

Intro

Compare those specifications to the GeForce GTX 560 Ti, which has core clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

GeForce GTS 150		32000 MB/sec
	Difference: 96256 (301%)

Texel Rate

The GeForce GTX 560 Ti is just a bit (more or less 11%) better at AF than the GeForce GTS 150. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 5248 (11%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 560 Ti is superior to the GeForce GTS 150, by far. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 14464 (122%)

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 data (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
