GeForce 920M vs GeForce 930M

Intro

The GeForce 920M comes with a clock frequency of 954 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the GeForce 930M, which features a GPU core clock speed of 928 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The GeForce 920M is a lot (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

The GeForce 920M should be a bit (approximately 3%) faster with regards to AA than the GeForce 930M, and will be 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.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
