GeForce 830M vs GeForce 9800 GT 1GB

Intro

Compare all of that to the GeForce 9800 GT 1GB, which comes with GPU core speed of 600 MHz, and 1024 MB of GDDR3 RAM running at 900 MHz through a 256-bit bus. It also is made up of 112 SPUs, 56 TAUs, and 16 ROPs.

GeForce 830M		14400 MB/sec
	Difference: 43200 (300%)

Texel Rate

The GeForce 9800 GT 1GB is a lot (approximately 104%) faster with regards to AF than the GeForce 830M. (explain)

GeForce 9800 GT 1GB		33600 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 17136 (104%)

Pixel Rate

The GeForce 9800 GT 1GB will be just a bit (about 17%) better at AA than the GeForce 830M, and able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 9800 GT 1GB		9600 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 1368 (17%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
