GeForce 9600 GT 512MB vs GeForce GTS 450

Intro

The GeForce 9600 GT 512MB comes with a core clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit memory bus, and uses a 65/55 nm design. It is made up of 64 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare those specifications to the GeForce GTS 450, which comes with GPU clock speed of 783 MHz, and 512 MB of GDDR5 memory running at 902 MHz through a 128-bit bus. It also is made up of 192 SPUs, 32 Texture Address Units, and 16 ROPs.

GeForce GTS 450 57728 MB/sec
GeForce 9600 GT 512MB 57600 MB/sec
Difference: 128 (0%)

Texel Rate

The GeForce GTS 450 should be a little bit (more or less 20%) faster with regards to anisotropic filtering than the GeForce 9600 GT 512MB. (explain)

GeForce GTS 450 25056 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 4256 (20%)

Pixel Rate

The GeForce GTS 450 should be a small bit (approximately 20%) better at AA than the GeForce 9600 GT 512MB, and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTS 450 12528 Mpixels/sec
GeForce 9600 GT 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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
