GeForce 810M vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which has a clock speed of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce 810M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M365X will be quite a bit (more or less 527%) more effective at AF than the GeForce 810M. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 31096 (527%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M365X is the winner, by far. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 11848 (401%)

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 (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
