GeForce GTS 150 vs GeForce GTX 560 Ti

Intro

Compare all that to the GeForce GTX 560 Ti, which has GPU core speed of 822 MHz, and 1024 MB of GDDR5 RAM running at 1002 MHz through a 256-bit bus. It also is made up of 384 Stream Processors, 64 Texture Address Units, and 32 ROPs.

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

Texel Rate

The GeForce GTX 560 Ti is a bit (approximately 11%) more effective 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 a high screen resolution is important to you, then the GeForce GTX 560 Ti is the winner, 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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
