GeForce GTX 460 SE vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which makes use of a 40 nm design. nVidia has clocked the core speed at 810 MHz. The GDDR5 RAM runs at a speed of 1001 MHz on this model. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 560 should be 18% faster than the GeForce GTX 460 SE overall, because of its greater bandwidth. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GTX 460 SE		108800 MB/sec
	Difference: 19328 (18%)

Texel Rate

The GeForce GTX 560 should be quite a bit (more or less 45%) better at AF than the GeForce GTX 460 SE. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 14160 (45%)

Pixel Rate

The GeForce GTX 560 will be quite a bit (approximately 25%) faster with regards to AA than the GeForce GTX 460 SE, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 5120 (25%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
