Compare any two graphics cards:
VS

GeForce 9600 GSO 768MB vs GeForce GT 230

Intro

The GeForce 9600 GSO 768MB comes with core speeds of 550 MHz on the GPU, and 800 MHz on the 768 MB of GDDR3 RAM. It features 96 SPUs along with 48 Texture Address Units and 12 Rasterization Operator Units.

Compare all of that to the GeForce GT 230, which has a core clock speed of 550 MHz and a DDR3 memory speed of 800 MHz. It also uses a 192-bit memory bus, and makes use of a 40 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, 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 the same. (explain)

Texel Rate

The GeForce 9600 GSO 768MB is quite a bit (approximately 200%) better at texture 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

If using lots of anti-aliasing is important to you, then the GeForce 9600 GSO 768MB is the winner, and very much so. (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 data (in units of MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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