GeForce 940M vs Radeon RX 5700

Intro

Compare that to the Radeon RX 5700, which has GPU clock speed of 1465 MHz, and 8096 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 5700 should be quite a bit faster than the GeForce 940M in general. (explain)

Radeon RX 5700		458752 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 442752 (2767%)

Texel Rate

The Radeon RX 5700 is quite a bit (more or less 720%) more effective at texture filtering than the GeForce 940M. (explain)

Radeon RX 5700		210960 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 185232 (720%)

Pixel Rate

The Radeon RX 5700 will be much (approximately 993%) better at FSAA than the GeForce 940M, and capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 5700		93760 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 85184 (993%)

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 largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
