GeForce 830M vs GeForce GT 230

Intro

Compare that to the GeForce GT 230, which comes with core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1536 MB of DDR3 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator 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

Performance-wise, the GeForce GT 230 should theoretically be quite a bit superior to the GeForce 830M in general. (explain)

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

Texel Rate

The GeForce 830M should be much (more or less 87%) better at anisotropic filtering 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 a high resolution is important to you, then the GeForce 830M is a better choice, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
