GeForce 920M vs GeForce 930M

Intro

Compare all of that to the GeForce 930M, which has a core clock frequency of 928 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce 920M should be quite a bit (approximately 37%) faster with regards to anisotropic filtering than the GeForce 930M. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 8256 (37%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 920M is a better choice, but only just. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 208 (3%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
