GeForce GTX 460 (OEM) vs GeForce GTX 560 Ti 448

Intro

Compare all of that to the GeForce GTX 560 Ti 448, which uses a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this particular model. It features 448 SPUs along with 56 Texture Address Units and 40 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 (OEM)		150 Watts
GeForce GTX 560 Ti 448		210 Watts
	Difference: 60 Watts (40%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti 448 should be 32% faster than the GeForce GTX 460 (OEM) in general, due to its higher data rate. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 35200 (32%)

Texel Rate

The GeForce GTX 560 Ti 448 should be just a bit (about 13%) more effective at texture filtering than the GeForce GTX 460 (OEM). (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 4592 (13%)

Pixel Rate

The GeForce GTX 560 Ti 448 will be quite a bit (about 41%) faster with regards to anti-aliasing than the GeForce GTX 460 (OEM), and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
GeForce GTX 460 (OEM)		20800 Mpixels/sec
	Difference: 8480 (41%)

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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at 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 graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
