GeForce 9600 GSO 768MB vs GeForce GT 450 (OEM)

Intro

Compare that to the GeForce GT 450 (OEM), which comes with GPU core speed of 790 MHz, and 1536 MB of GDDR5 RAM running at 1000 MHz through a 192-bit bus. It also is comprised of 144 Stream Processors, 24 Texture Address Units, and 24 Raster Operation Units.

GeForce GT 450 (OEM)		106 Watts
	Difference: 22 Watts (26%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 450 (OEM) will be 150% quicker than the GeForce 9600 GSO 768MB in general, because of its higher data rate. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 57600 (150%)

Texel Rate

The GeForce 9600 GSO 768MB will be quite a bit (about 39%) faster with regards to AF than the GeForce GT 450 (OEM). (explain)

GeForce 9600 GSO 768MB		26400 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 7440 (39%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 450 (OEM) is a better choice, by far. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce 9600 GSO 768MB		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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
