GeForce GTX 1050 3GB vs Radeon R9 M385X

Intro

Compare all that to the Radeon R9 M385X, which uses a 28 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this particular model. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should in theory be a small bit faster than the GeForce GTX 1050 3GB overall. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 9984 (12%)

Texel Rate

The GeForce GTX 1050 3GB should be a little bit (about 8%) better at texture filtering than the Radeon R9 M385X. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 5216 (8%)

Pixel Rate

The GeForce GTX 1050 3GB should be a lot (more or less 90%) better at full screen anti-aliasing than the Radeon R9 M385X, and able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 15808 (90%)

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 (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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