GeForce GTX 960M vs Radeon R9 M365X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X should in theory be just a bit faster than the GeForce GTX 960M in general. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 960M should be a bit (about 18%) faster with regards to anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 6840 (18%)

Pixel Rate

The GeForce GTX 960M will be a bit (more or less 18%) more effective at anti-aliasing than the Radeon R9 M365X, and should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 2736 (18%)

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 maximum amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
