GeForce 810M vs Radeon R9 Nano

Intro

Compare those specifications to the Radeon R9 Nano, which features GPU clock speed of 1000 MHz, and 4096 MB of HBM RAM running at 500 MHz through a 4096-bit bus. It also is comprised of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

GeForce 810M		5904 Mtexels/sec
	Difference: 250096 (4236%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 Nano is a better choice, by far. (explain)

Radeon R9 Nano		64000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 61048 (2068%)

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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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