GeForce GTX 960M vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which comes with a clock frequency of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M380 should in theory be a lot superior to the GeForce GTX 960M in general. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 32000 (50%)

Texel Rate

The GeForce GTX 960M is just a bit (more or less 10%) more effective at texture filtering than the Radeon R9 M380. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 3840 (10%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 960M is the winner, though not by far. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 1536 (10%)

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 largest amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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