GeForce 840M vs Radeon RX 5500 XT

Intro

Compare those specifications to the Radeon RX 5500 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1717 MHz. The GDDR6 RAM works at a frequency of 1750 MHz on this specific model. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.

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 overall, due to its higher data rate. (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 a lot (approximately 512%) more effective at AF than the GeForce 840M. (explain)

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

Pixel Rate

If running with 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 (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
