GeForce GT 450 (OEM) vs GeForce GTX 260

Intro

Compare that to the GeForce GTX 260, which has clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 192 SPUs as well as 64 TAUs and 28 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
GeForce GTX 260		182 Watts
	Difference: 76 Watts (72%)

Memory Bandwidth

In theory, the GeForce GTX 260 is 17% faster than the GeForce GT 450 (OEM) overall, because of its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 260 should be quite a bit (more or less 94%) better at AF 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 using a high resolution is important to you, then the GeForce GT 450 (OEM) is superior to the GeForce GTX 260, but only just. (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 max amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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