GeForce 920M vs GeForce 930M

Intro

Compare those specifications to the GeForce 930M, which has GPU clock speed of 928 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The GeForce 920M should be much (about 37%) faster with regards to texture filtering than the GeForce 930M. (explain)

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

Pixel Rate

The GeForce 920M is just a bit (about 3%) better at full screen anti-aliasing than the GeForce 930M, and able to handle higher screen resolutions while still performing well. (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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
