GeForce 810M vs Radeon HD 7750

Intro

Compare that to the Radeon HD 7750, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this card. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator 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

The Radeon HD 7750 should in theory be a lot faster than 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 is quite a bit (more or less 334%) faster with regards to AF 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 should be much (more or less 334%) faster with regards to AA than the GeForce 810M, and also able to handle higher screen resolutions without losing too much performance. (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: Bandwidth is the max amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
