GeForce 810M vs Radeon HD 6970

Intro

Compare that to the Radeon HD 6970, which comes with GPU core speed of 880 MHz, and 2048 MB of GDDR5 memory set to run at 1375 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 96 TAUs, and 32 ROPs.

GeForce 810M		15 Watts
Radeon HD 6970		250 Watts
	Difference: 235 Watts (1567%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6970 should be much faster than the GeForce 810M overall. (explain)

Radeon HD 6970		176000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 161600 (1122%)

Texel Rate

The Radeon HD 6970 will be quite a bit (approximately 1331%) more effective at anisotropic filtering than the GeForce 810M. (explain)

Radeon HD 6970		84480 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 78576 (1331%)

Pixel Rate

The Radeon HD 6970 should be a lot (more or less 854%) better at full screen anti-aliasing than the GeForce 810M, and also will be capable of handling higher resolutions while still performing well. (explain)

Radeon HD 6970		28160 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 25208 (854%)

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 maximum amount of information (counted in MB 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 speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
