GeForce 830M vs GeForce 9500 GT DDR2

Intro

The GeForce 830M has core clock speeds of 1029 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 256 SPUs along with 16 Texture Address Units and 8 ROPs.

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M 25 Watts
GeForce 9500 GT DDR2 50 Watts
Difference: 25 Watts (100%)

Memory Bandwidth

In theory, the GeForce 9500 GT DDR2 should be 11% faster than the GeForce 830M in general, because of its higher data rate. (explain)

GeForce 9500 GT DDR2 16000 MB/sec
GeForce 830M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 830M is quite a bit (about 87%) more effective 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

If using a high resolution is important to you, then the GeForce 830M is a better choice, by a large margin. (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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write 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 the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
