GeForce GT 450 (OEM) vs GeForce GTX 465

Intro

Compare that to the GeForce GTX 465, which has a core clock speed of 607 MHz and a GDDR5 memory speed of 802 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It features 352 SPUs, 44 TAUs, and 32 Raster Operation Units.

GeForce GTX 465		102592 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 6592 (7%)

Texel Rate

The GeForce GTX 465 is much (about 41%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

GeForce GTX 465		26708 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 7748 (41%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 465 is the winner, not by a very large margin though. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 464 (2%)

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 (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
