GeForce 930M vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which features GPU clock speed of 700 MHz, and 1024 MB of GDDR5 memory set to run at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) Stream Processors, 36 TAUs, and 16 Raster Operation Units.

GeForce 930M		22272 Mtexels/sec
	Difference: 2928 (13%)

Pixel Rate

The Radeon HD 5750 1GB will be a lot (approximately 51%) more effective at anti-aliasing than the GeForce 930M, and also able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 3776 (51%)

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 data (counted in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's 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 rate also depends 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.
