GeForce GTX 275 vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which features clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 560		150 Watts
GeForce GTX 275		219 Watts
	Difference: 69 Watts (46%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 560 should theoretically be just a bit better than the GeForce GTX 275 in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GTX 275		127008 MB/sec
	Difference: 1120 (1%)

Texel Rate

The GeForce GTX 275 is a bit (more or less 12%) more effective at texture filtering than the GeForce GTX 560. (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 5280 (12%)

Pixel Rate

The GeForce GTX 560 will be quite a bit (about 46%) more effective at full screen anti-aliasing than the GeForce GTX 275, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 8196 (46%)

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 MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
