GeForce 930M vs GeForce GTX 750

Intro

Compare all of that to the GeForce GTX 750, which comes with a clock speed of 1020 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 750 should in theory be quite a bit superior to the GeForce 930M overall. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 65600 (456%)

Texel Rate

The GeForce GTX 750 will be quite a bit (about 47%) more effective at AF than the GeForce 930M. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 10368 (47%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 750 is a better choice, and very much so. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 8896 (120%)

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 moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
