GeForce 9600 GT 1GB vs GeForce GTX 550 Ti

Intro

The GeForce 9600 GT 1GB uses a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular card. It features 64 SPUs along with 32 TAUs and 16 ROPs.

Compare that to the GeForce GTX 550 Ti, which has clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs along with 32 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB 95 Watts
GeForce GTX 550 Ti 116 Watts
Difference: 21 Watts (22%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 550 Ti should perform quite a bit faster than the GeForce 9600 GT 1GB overall. (explain)

GeForce GTX 550 Ti 98496 MB/sec
GeForce 9600 GT 1GB 57600 MB/sec
Difference: 40896 (71%)

Texel Rate

The GeForce GTX 550 Ti should be a lot (more or less 38%) better at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

GeForce GTX 550 Ti 28800 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 8000 (38%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 550 Ti is the winner, and very much so. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
GeForce 9600 GT 1GB 10400 Mpixels/sec
Difference: 11200 (108%)

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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR 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 amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
