GeForce GTX 260 Core 216 vs GeForce GTX 460 SE

Intro

Compare those specs to the GeForce GTX 460 SE, which features clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 288 SPUs as well as 48 TAUs and 32 ROPs.

Texel Rate

The GeForce GTX 260 Core 216 will be much (more or less 33%) more effective at anisotropic filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 10272 (33%)

Pixel Rate

The GeForce GTX 460 SE is quite a bit (more or less 29%) more effective at FSAA than the GeForce GTX 260 Core 216, and should be able to handle higher resolutions better. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GTX 260 Core 216		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: 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. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling 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 record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
