GeForce 810M vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which features core clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M365X should in theory be much superior to the GeForce 810M overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M365X will be a lot (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 using lots of anti-aliasing is important to you, then the Radeon R9 M365X is a better choice, and very much so. (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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
