GeForce GTX 1050 vs Radeon R9 M380

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 1050 should be just a bit faster than the Radeon R9 M380 overall. (explain)

GeForce GTX 1050		114688 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 18688 (19%)

Texel Rate

The GeForce GTX 1050 will be a lot (more or less 35%) more effective at AF than the Radeon R9 M380. (explain)

GeForce GTX 1050		54160 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 14160 (35%)

Pixel Rate

The GeForce GTX 1050 is much (approximately 171%) better at full screen anti-aliasing than the Radeon R9 M380, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 27328 (171%)

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 (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number is calculated by multiplying the total number 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 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
