GeForce GTX 960 vs Radeon R9 M380

Intro

Compare all that to the Radeon R9 M380, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Radeon R9 M380		96000 MB/sec
	Difference: 16000 (17%)

Texel Rate

The GeForce GTX 960 will be much (more or less 80%) faster with regards to anisotropic filtering than the Radeon R9 M380. (explain)

GeForce GTX 960		72128 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 32128 (80%)

Pixel Rate

The GeForce GTX 960 will be much (more or less 125%) faster with regards to FSAA than the Radeon R9 M380, and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 960		36064 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 20064 (125%)

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 information (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write 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 card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
