GeForce 930M vs Geforce GTX 670

Intro

Compare all that to the Geforce GTX 670, which makes use of a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this specific model. It features 1344 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Geforce GTX 670 should be 1233% quicker than the GeForce 930M overall, due to its greater bandwidth. (explain)

Geforce GTX 670		192000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 177600 (1233%)

Texel Rate

The Geforce GTX 670 is quite a bit (approximately 360%) more effective at AF than the GeForce 930M. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 80208 (360%)

Pixel Rate

The Geforce GTX 670 should be a lot (more or less 294%) better at anti-aliasing than the GeForce 930M, and also able to handle higher resolutions without losing too much performance. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 21856 (294%)

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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the potential to get to the maximum fill rate.
