GeForce GTX 860M vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has clocked the core frequency at 925 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X should in theory be just a bit faster than the GeForce GTX 860M in general. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GTX 860M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 860M should be much (about 107%) faster with regards to AF than the Radeon R9 M365X. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 39512 (107%)

Pixel Rate

The Radeon R9 M365X is just a bit (more or less 16%) more effective at FSAA than the GeForce GTX 860M, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GTX 860M		12752 Mpixels/sec
	Difference: 2048 (16%)

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 (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, 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 number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
