Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 9600 GT 1GB features core speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 64 SPUs along with 32 Texture Address Units and 16 ROPs.
Compare those specifications to the GeForce GT 430 1GB, which has a core clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 16 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce 9600 GT 1GB should in theory be a lot superior to the GeForce GT 430 1GB overall. (explain)
Texel RateThe GeForce 9600 GT 1GB is a lot (more or less 86%) faster with regards to anisotropic filtering than the GeForce GT 430 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 9600 GT 1GB is a better choice, by a large margin. (explain)
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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock 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 in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
