GeForce 940M vs Radeon RX 5700

Intro

Compare those specs to the Radeon RX 5700, which has GPU core speed of 1465 MHz, and 8096 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also is made up of 2304 Stream Processors, 144 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 5700 should theoretically be much better than the GeForce 940M overall. (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 (approximately 720%) more effective at AF 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 a lot (approximately 993%) better at FSAA than the GeForce 940M, and also should be able to handle higher resolutions while still performing well. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, 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 number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
