GeForce GTS 150 vs GeForce GTX 560 Ti

Intro

Compare those specs to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 RAM is set to run at a speed of 1002 MHz on this particular model. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

GeForce GTS 150		141 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 29 Watts (21%)

Memory Bandwidth

Theoretically, the GeForce GTX 560 Ti should perform a lot faster than the GeForce GTS 150 overall. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 96256 (301%)

Texel Rate

The GeForce GTX 560 Ti should be a small bit (approximately 11%) faster with regards to 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 running with high levels of AA is important to you, then the GeForce GTX 560 Ti is superior to the GeForce GTS 150, and very much so. (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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 potential to get to the max fill rate.
