GeForce GTX 275 vs GeForce GTX 560 Ti

Intro

Compare those specifications to the GeForce GTX 560 Ti, which uses a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 memory runs at a frequency of 1002 MHz on this specific card. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 Ti		170 Watts
GeForce GTX 275		219 Watts
	Difference: 49 Watts (29%)

Memory Bandwidth

The GeForce GTX 560 Ti, in theory, should perform a bit faster than the GeForce GTX 275 overall. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce GTX 275		127008 MB/sec
	Difference: 1248 (1%)

Texel Rate

The GeForce GTX 560 Ti will be a small bit (approximately 4%) more effective at anisotropic filtering than the GeForce GTX 275. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 1968 (4%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 560 Ti is superior to the GeForce GTX 275, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 8580 (48%)

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 information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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