GeForce GT 450 (OEM) vs GeForce GTX 260 216SP 55 nm

Intro

Compare all of that to the GeForce GTX 260 216SP 55 nm, which has a clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit memory bus, and uses a 55 nm design. It features 216 SPUs, 72 TAUs, and 28 ROPs.

	Difference: 15888 (17%)

Texel Rate

The GeForce GTX 260 216SP 55 nm is a lot (more or less 119%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 22512 (119%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 450 (OEM) is the winner, but it probably won't make a huge difference. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce GTX 260 216SP 55 nm		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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
