GeForce 8800 GS vs GeForce GT 450 (OEM)

Intro

Compare all that to the GeForce GT 450 (OEM), which comes with a core clock speed of 790 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 192-bit bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 ROPs.

GeForce 8800 GS		105 Watts
GeForce GT 450 (OEM)		106 Watts
	Difference: 1 Watts (1%)

Memory Bandwidth

The GeForce GT 450 (OEM) should in theory perform a lot faster than the GeForce 8800 GS in general. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 57600 (150%)

Texel Rate

The GeForce 8800 GS will be a lot (more or less 39%) more effective at AF than the GeForce GT 450 (OEM). (explain)

GeForce 8800 GS		26400 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 7440 (39%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) is the winner, and very much so. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 12360 (187%)

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 information (measured in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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