GeForce 810M vs Radeon HD 5850

Intro

Compare those specifications to the Radeon HD 5850, which comes with GPU clock speed of 725 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also is comprised of 1440(288x5) Stream Processors, 72 TAUs, and 32 Raster Operation Units.

GeForce 810M		15 Watts
Radeon HD 5850		151 Watts
	Difference: 136 Watts (907%)

Memory Bandwidth

In theory, the Radeon HD 5850 should be quite a bit faster than the GeForce 810M in general. (explain)

Radeon HD 5850		128000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 113600 (789%)

Texel Rate

The Radeon HD 5850 is a lot (more or less 784%) faster with regards to AF than the GeForce 810M. (explain)

Radeon HD 5850		52200 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 46296 (784%)

Pixel Rate

The Radeon HD 5850 is much (about 686%) better at FSAA than the GeForce 810M, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 5850		23200 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 20248 (686%)

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 (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
