GeForce 830M vs GeForce 9600 GT 512MB

Intro

Compare all of that to the GeForce 9600 GT 512MB, which comes with GPU clock speed of 650 MHz, and 512 MB of GDDR3 RAM running at 900 MHz through a 256-bit bus. It also features 64 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

GeForce 830M		16464 Mtexels/sec
	Difference: 4336 (26%)

Pixel Rate

The GeForce 9600 GT 512MB should be much (approximately 26%) faster with regards to anti-aliasing than the GeForce 830M, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 9600 GT 512MB		10400 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 2168 (26%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
