GeForce 830M vs GeForce GT 230

Intro

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

Compare those specifications to the GeForce GT 230, which features a GPU core clock speed of 550 MHz, and 1536 MB of DDR3 RAM running at 800 MHz through a 192-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M 25 Watts
GeForce GT 230 65 Watts
Difference: 40 Watts (160%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 230 should be 167% quicker than the GeForce 830M in general, due to its greater bandwidth. (explain)

GeForce GT 230 38400 MB/sec
GeForce 830M 14400 MB/sec
Difference: 24000 (167%)

Texel Rate

The GeForce 830M will be much (approximately 87%) more effective at AF than the GeForce GT 230. (explain)

GeForce 830M 16464 Mtexels/sec
GeForce GT 230 8800 Mtexels/sec
Difference: 7664 (87%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 830M is superior to the GeForce GT 230, by far. (explain)

GeForce 830M 8232 Mpixels/sec
GeForce GT 230 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 data (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
