GeForce 810M vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which has core clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should be quite a bit faster than the GeForce 810M overall. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 81600 (567%)

Texel Rate

The Radeon R9 M385X is a lot (about 943%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 55696 (943%)

Pixel Rate

The Radeon R9 M385X will be a lot (about 496%) better at FSAA than the GeForce 810M, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 14648 (496%)

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 max amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
