Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTS 450 1GB		106 Watts
GeForce GTX 260 216SP 55 nm		171 Watts
	Difference: 65 Watts (61%)

Memory Bandwidth

In theory, the GeForce GTX 260 216SP 55 nm will be 94% quicker than the GeForce GTS 450 1GB overall, due to its greater data rate. (explain)

GeForce GTX 260 216SP 55 nm		111888 MB/sec
GeForce GTS 450 1GB		57728 MB/sec
	Difference: 54160 (94%)

Texel Rate

The GeForce GTX 260 216SP 55 nm should be quite a bit (more or less 66%) more effective at texture filtering than the GeForce GTS 450 1GB. (explain)

GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 16416 (66%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 260 216SP 55 nm is superior to the GeForce GTS 450 1GB, and very much so. (explain)

GeForce GTX 260 216SP 55 nm		16128 Mpixels/sec
GeForce GTS 450 1GB		12528 Mpixels/sec
	Difference: 3600 (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 (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of 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 amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
