GeForce 940M vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which has a clock frequency of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 460 2GB should theoretically be quite a bit better than the GeForce 940M overall. (explain)

Radeon RX 460 2GB		112000 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 96000 (600%)

Texel Rate

The Radeon RX 460 2GB should be a lot (about 137%) more effective at anisotropic filtering than the GeForce 940M. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 35312 (137%)

Pixel Rate

The Radeon RX 460 2GB is quite a bit (more or less 103%) more effective at AA than the GeForce 940M, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 8864 (103%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. 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 - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
