Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce GT 430 1GB
IntroThe GeForce 8600 GT 256MB GDDR3 makes use of a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 RAM is set to run at a frequency of 700 MHz on this particular card. It features 32 SPUs along with 16 TAUs and 8 ROPs.
Compare all that to the GeForce GT 430 1GB, which features GPU clock speed of 700 MHz, and 1024 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also features 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GT 430 1GB should in theory be much superior to the GeForce 8600 GT 256MB GDDR3 in general. (explain)
Texel RateThe GeForce GT 430 1GB should be a lot (more or less 30%) faster with regards to AF than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateThe GeForce 8600 GT 256MB GDDR3 is a lot (approximately 54%) better at FSAA than the GeForce GT 430 1GB, and should be able to handle higher resolutions more effectively. (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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
