Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
GeForce GTX 260 Core 216		202 Watts
	Difference: 96 Watts (91%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 Core 216 is 17% faster than the GeForce GT 450 (OEM) in general, because of its greater data rate. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 15888 (17%)

Texel Rate

The GeForce GTX 260 Core 216 is much (approximately 119%) faster with regards to AF than the GeForce GT 450 (OEM). (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 22512 (119%)

Pixel Rate

The GeForce GT 450 (OEM) should be just a bit (approximately 18%) more effective at FSAA than the GeForce GTX 260 Core 216, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 2832 (18%)

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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
