GeForce 810M vs Radeon HD 5970

Intro

Compare all of that to the Radeon HD 5970, which makes use of a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 1600 SPUs as well as 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon HD 5970		294 Watts
	Difference: 279 Watts (1860%)

Memory Bandwidth

As far as performance goes, the Radeon HD 5970 should in theory be a lot better than the GeForce 810M in general. (explain)

Radeon HD 5970		256000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 241600 (1678%)

Texel Rate

The Radeon HD 5970 will be quite a bit (approximately 3830%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

Radeon HD 5970		232000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 226096 (3830%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5970 is a better choice, by far. (explain)

Radeon HD 5970		92800 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 89848 (3044%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of 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 speed of the chip. The higher this number, 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 could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
