GeForce 830M vs GeForce GT 210

Intro

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

Compare all of that to the GeForce GT 210, which comes with a core clock speed of 589 MHz and a DDR3 memory speed of 800 MHz. It also features a 64-bit memory bus, and uses a 40 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M 25 Watts
GeForce GT 210 31 Watts
Difference: 6 Watts (24%)

Memory Bandwidth

Theoretically speaking, the GeForce 830M should be 13% quicker than the GeForce GT 210 in general, because of its higher bandwidth. (explain)

GeForce 830M 14400 MB/sec
GeForce GT 210 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 830M will be much (about 249%) faster with regards to texture filtering than the GeForce GT 210. (explain)

GeForce 830M 16464 Mtexels/sec
GeForce GT 210 4712 Mtexels/sec
Difference: 11752 (249%)

Pixel Rate

The GeForce 830M should be a lot (about 249%) faster with regards to full screen anti-aliasing than the GeForce GT 210, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce 830M 8232 Mpixels/sec
GeForce GT 210 2356 Mpixels/sec
Difference: 5876 (249%)

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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
