GeForce 830M vs GeForce 9500 GT DDR2

Intro

The GeForce 830M makes use of a 28 nm design. nVidia has set the core frequency at 1029 MHz. The DDR3 memory works at a frequency of 900 MHz on this card. It features 256 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

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 features 32 SPUs, 16 Texture Address Units, 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

Theoretically speaking, the GeForce 9500 GT DDR2 should be 11% quicker than the GeForce 830M in general, because of its greater data rate. (explain)

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

Texel Rate

The GeForce 830M will be a lot (more or less 87%) better at AF 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 running with a high resolution is important to you, then the GeForce 830M is superior to the GeForce 9500 GT DDR2, and very much so. (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 (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
