GeForce 810M vs Radeon HD 4870 X2

Intro

Compare those specs to the Radeon HD 4870 X2, which comes with a core clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

GeForce 810M		14400 MB/sec
	Difference: 216000 (1500%)

Texel Rate

The Radeon HD 4870 X2 should be much (about 916%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

Radeon HD 4870 X2		60000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 54096 (916%)

Pixel Rate

The Radeon HD 4870 X2 is a lot (more or less 713%) more effective at FSAA than the GeForce 810M, and also able to handle higher resolutions more effectively. (explain)

Radeon HD 4870 X2		24000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 21048 (713%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
