GeForce 930M vs GeForce GT 430

Intro

Compare those specs to the GeForce GT 430, which has a core clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GT 430 should theoretically be a lot superior to the GeForce 930M in general. (explain)

GeForce GT 430		28800 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The GeForce 930M is much (more or less 99%) faster with regards to AF than the GeForce GT 430. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 11072 (99%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 930M is a better choice, by far. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 4624 (165%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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