GeForce 930M vs GeForce GTX 650

Intro

Compare all that to the GeForce GTX 650, which features a core clock frequency of 1058 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650, in theory, should perform quite a bit faster than the GeForce 930M overall. (explain)

GeForce GTX 650		80000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 65600 (456%)

Texel Rate

The GeForce GTX 650 should be quite a bit (approximately 52%) more effective at AF than the GeForce 930M. (explain)

GeForce GTX 650		33856 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 11584 (52%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 is superior to the GeForce 930M, and very much so. (explain)

GeForce GTX 650		16928 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 9504 (128%)

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 data (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
