GeForce 830M vs GeForce 9500 GT DDR2

Intro

The GeForce 830M has a clock speed of 1029 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It features 256 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare that to the GeForce 9500 GT DDR2, which comes with a core clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also uses a 128-bit memory bus, and makes use of a 65 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 ROPs.

GeForce 830M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 830M will be quite a bit (more or less 87%) better at texture filtering than the GeForce 9500 GT DDR2. (explain)

GeForce 830M 16464 Mtexels/sec
GeForce 9500 GT DDR2 8800 Mtexels/sec
Difference: 7664 (87%)

Pixel Rate

The GeForce 830M should be much (more or less 87%) faster with regards to FSAA than the GeForce 9500 GT DDR2, and will be able to handle higher screen resolutions while still performing well. (explain)

GeForce 830M 8232 Mpixels/sec
GeForce 9500 GT DDR2 4400 Mpixels/sec
Difference: 3832 (87%)

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 maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
