GeForce GTX 950 vs Radeon R9 M380

Intro

Compare all that to the Radeon R9 M380, which comes with core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 950 should in theory be just a bit better than the Radeon R9 M380 in general. (explain)

GeForce GTX 950		105728 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 9728 (10%)

Texel Rate

The GeForce GTX 950 is a lot (approximately 23%) more effective at AF than the Radeon R9 M380. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 9152 (23%)

Pixel Rate

The GeForce GTX 950 is a lot (more or less 105%) faster with regards to anti-aliasing than the Radeon R9 M380, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 16768 (105%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that 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 Raster Operations Pipelines by the the card's clock speed. 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
