GeForce 9600 GT 512MB vs GeForce GT 450 (OEM)

Intro

Compare all of that to the GeForce GT 450 (OEM), which uses a 40 nm design. nVidia has clocked the core speed at 790 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this card. It features 144 SPUs along with 24 TAUs and 24 ROPs.

The GeForce 9600 GT 512MB is a bit (about 10%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)

GeForce 9600 GT 512MB		20800 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 1840 (10%)

Pixel Rate

The GeForce GT 450 (OEM) should be much (more or less 82%) more effective at FSAA than the GeForce 9600 GT 512MB, and able to handle higher screen resolutions while still performing well. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce 9600 GT 512MB		10400 Mpixels/sec
	Difference: 8560 (82%)

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 (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
