GeForce GT 450 (OEM) vs GeForce GTX 260

Intro

Compare all that to the GeForce GTX 260, which makes use of a 65 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 RAM runs at a frequency of 999 MHz on this card. It features 192 SPUs as well as 64 TAUs and 28 Rasterization Operator Units.

Texel Rate

The GeForce GTX 260 will be much (about 94%) faster with regards to texture filtering than the GeForce GT 450 (OEM). (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 17904 (94%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 450 (OEM) is a better choice, though only just barely. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce GTX 260		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 (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
