GeForce 810M vs Radeon HD 5970

Intro

Compare those specifications to the Radeon HD 5970, which comes with a clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is made up of 1600 SPUs, 160 TAUs, and 64 ROPs.

GeForce 810M		14400 MB/sec
	Difference: 241600 (1678%)

Texel Rate

The Radeon HD 5970 should be a lot (approximately 3830%) faster with regards to AF than the GeForce 810M. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5970 is a better choice, and very much so. (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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
