GeForce 930M vs GeForce GT 230

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 230 should perform a lot faster than the GeForce 930M in general. (explain)

GeForce GT 230		38400 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 24000 (167%)

Texel Rate

The GeForce 930M is quite a bit (more or less 153%) faster with regards to AF than the GeForce GT 230. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 13472 (153%)

Pixel Rate

The GeForce 930M will be much (more or less 69%) faster with regards to full screen anti-aliasing than the GeForce GT 230, and capable of handling higher resolutions more effectively. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 3024 (69%)

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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
