GeForce 930M vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which has GPU clock speed of 725 MHz, and 512 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 6750 should theoretically perform quite a bit faster than the GeForce 930M overall. (explain)

Radeon HD 6750		64000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The Radeon HD 6750 is just a bit (more or less 17%) better at texture filtering than the GeForce 930M. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 3828 (17%)

Pixel Rate

The Radeon HD 6750 is quite a bit (more or less 56%) more effective at full screen anti-aliasing than the GeForce 930M, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 4176 (56%)

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 information (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
