GeForce 810M vs Radeon HD 7750

Intro

Compare those specifications to the Radeon HD 7750, which features a core clock frequency of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon HD 7750		55 Watts
	Difference: 40 Watts (267%)

Memory Bandwidth

Performance-wise, the Radeon HD 7750 should theoretically be quite a bit superior to the GeForce 810M overall. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

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

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 7750 is a better choice, and very much so. (explain)

Radeon HD 7750		12800 Mpixels/sec
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 information (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
