GeForce 920M vs Radeon RX 5700

Intro

Compare those specs to the Radeon RX 5700, which comes with a GPU core clock speed of 1465 MHz, and 8096 MB of GDDR6 RAM running at 1750 MHz through a 256-bit bus. It also features 2304 SPUs, 144 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 is 3086% quicker than the GeForce 920M overall, because of its higher bandwidth. (explain)

Radeon RX 5700		458752 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 444352 (3086%)

Texel Rate

The Radeon RX 5700 should be quite a bit (more or less 591%) better at texture filtering than the GeForce 920M. (explain)

Radeon RX 5700		210960 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 180432 (591%)

Pixel Rate

The Radeon RX 5700 will be quite a bit (approximately 1129%) more effective at FSAA than the GeForce 920M, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 5700		93760 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 86128 (1129%)

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 information (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 fill 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 potential to get to the maximum fill rate.
