GeForce 9600 GSO 512MB vs GeForce GTS 450

Intro

The GeForce 9600 GSO 512MB uses a 65/55 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 memory works at a frequency of 900 MHz on this specific model. It features 96 SPUs along with 48 Texture Address Units and 16 Rasterization Operator Units.

Compare all that to the GeForce GTS 450, which uses a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 memory is set to run at a frequency of 902 MHz on this specific card. It features 192 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

GeForce 9600 GSO 512MB 57600 MB/sec
Difference: 128 (0%)

Texel Rate

The GeForce 9600 GSO 512MB is quite a bit (approximately 25%) more effective at texture filtering than the GeForce GTS 450. (explain)

GeForce 9600 GSO 512MB 31200 Mtexels/sec
GeForce GTS 450 25056 Mtexels/sec
Difference: 6144 (25%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTS 450 is the winner, though only just barely. (explain)

GeForce GTS 450 12528 Mpixels/sec
GeForce 9600 GSO 512MB 10400 Mpixels/sec
Difference: 2128 (20%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video 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 maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
