GeForce GTX 960M vs Radeon R9 M380

Intro

Compare all that to the Radeon R9 M380, which uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory is set to run at a speed of 1500 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M380 should in theory be much 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 should be a little bit (more or less 10%) better at AF than the Radeon R9 M380. (explain)

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

Pixel Rate

The GeForce GTX 960M is a small bit (about 10%) better at anti-aliasing than the Radeon R9 M380, and also will be capable of handling higher resolutions more effectively. (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
