GeForce GTX 260 Core 216 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 frequency at 822 MHz. The GDDR5 memory runs at a speed of 1002 MHz on this model. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 16368 (15%)

Texel Rate

The GeForce GTX 560 Ti should be much (approximately 27%) faster with regards to texture filtering than the GeForce GTX 260 Core 216. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 11136 (27%)

Pixel Rate

The GeForce GTX 560 Ti should be quite a bit (about 63%) more effective at AA than the GeForce GTX 260 Core 216, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 10176 (63%)

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 (measured in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
