GeForce 810M vs Radeon HD 7750

Intro

Compare those specifications to the Radeon HD 7750, which has a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

GeForce 810M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon HD 7750 should be a lot (more or less 334%) more effective at anisotropic filtering than the GeForce 810M. (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 19696 (334%)

Pixel Rate

The Radeon HD 7750 is a lot (more or less 334%) more effective at FSAA than the GeForce 810M, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce 810M		2952 Mpixels/sec
	Difference: 9848 (334%)

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 megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 fill 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 maximum fill rate.
