GeForce 940M vs Radeon HD 5750 512MB

Intro

Compare all of that to the Radeon HD 5750 512MB, which uses a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM works at a frequency of 1150 MHz on this specific card. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 512MB should be 360% quicker than the GeForce 940M overall, due to its higher data rate. (explain)

Radeon HD 5750 512MB		73600 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 57600 (360%)

Texel Rate

The GeForce 940M is just a bit (approximately 2%) more effective at anisotropic filtering than the Radeon HD 5750 512MB. (explain)

GeForce 940M		25728 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 528 (2%)

Pixel Rate

The Radeon HD 5750 512MB will be much (approximately 31%) better at FSAA than the GeForce 940M, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 5750 512MB		11200 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 2624 (31%)

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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
