GeForce 9600 GSO 768MB vs GeForce GT 230

Intro

The GeForce 9600 GSO 768MB uses a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 memory works at a frequency of 800 MHz on this model. It features 96 SPUs as well as 48 Texture Address Units and 12 Rasterization Operator Units.

Compare all that to the GeForce GT 230, which features a GPU core clock speed of 550 MHz, and 1536 MB of DDR3 memory running at 800 MHz through a 192-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230 65 Watts
GeForce 9600 GSO 768MB 84 Watts
Difference: 19 Watts (29%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce 9600 GSO 768MB should be a lot (approximately 200%) more effective at anisotropic filtering than the GeForce GT 230. (explain)

GeForce 9600 GSO 768MB 26400 Mtexels/sec
GeForce GT 230 8800 Mtexels/sec
Difference: 17600 (200%)

Pixel Rate

The GeForce 9600 GSO 768MB is quite a bit (about 50%) faster with regards to anti-aliasing than the GeForce GT 230, and also capable of handling higher resolutions without slowing down too much. (explain)

GeForce 9600 GSO 768MB 6600 Mpixels/sec
GeForce GT 230 4400 Mpixels/sec
Difference: 2200 (50%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling 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 that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
