GeForce GT 450 (OEM) vs GeForce GTX 460 SE

Intro

Compare those specifications 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 along with 48 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 44 Watts (42%)

Memory Bandwidth

The GeForce GTX 460 SE, in theory, should perform just a bit faster than the GeForce GT 450 (OEM) overall. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 12800 (13%)

Texel Rate

The GeForce GTX 460 SE is quite a bit (approximately 65%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 12240 (65%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 SE is a better choice, though not by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 1840 (10%)

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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
