GeForce 840M vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which has clock speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 840M		30 Watts
Radeon RX 5500 XT		130 Watts
	Difference: 100 Watts (333%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 XT will be 1334% faster than the GeForce 840M in general, due to its greater bandwidth. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce 840M		16000 MB/sec
	Difference: 213376 (1334%)

Texel Rate

The Radeon RX 5500 XT should be much (about 512%) more effective at texture filtering than the GeForce 840M. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce 840M		24696 Mtexels/sec
	Difference: 126400 (512%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5500 XT is superior to the GeForce 840M, by far. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce 840M		8232 Mpixels/sec
	Difference: 46712 (567%)

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 (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied 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 better the texel rate, the better the graphics 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 video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
