GeForce GTX 260 vs GeForce GTX 460 (OEM)

Intro

Compare that to the GeForce GTX 460 (OEM), which features GPU clock speed of 650 MHz, and 1024 MB of GDDR5 memory set to run at 850 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 TAUs, and 32 Raster Operation Units.

GeForce GTX 460 (OEM)		150 Watts
GeForce GTX 260		182 Watts
	Difference: 32 Watts (21%)

Memory Bandwidth

In theory, the GeForce GTX 260 should perform a little bit faster than the GeForce GTX 460 (OEM) in general. (explain)

GeForce GTX 260		111888 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 3088 (3%)

Texel Rate

The GeForce GTX 260 should be just a bit (more or less 1%) faster with regards to anisotropic filtering than the GeForce GTX 460 (OEM). (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 464 (1%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 (OEM) is the winner, and very much so. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 4672 (29%)

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 information (in units of MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
