GeForce 830M vs GeForce 9500 GT 1GB GDDR3

Intro

The GeForce 830M uses a 28 nm design. nVidia has set the core frequency at 1029 MHz. The DDR3 RAM works at a speed of 900 MHz on this particular model. It features 256 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the GeForce 9500 GT 1GB GDDR3, which makes use of a 55 nm design. nVidia has set the core speed at 550 MHz. The GDDR3 memory works at a frequency of 800 MHz on this particular card. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

The GeForce 830M is much (about 87%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce 830M 16464 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 7664 (87%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 830M is the winner, by far. (explain)

GeForce 830M 8232 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 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 (in units of MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at 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 graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
