Radeon RX 5700 vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1825 MHz. The GDDR6 memory works at a speed of 2000 MHz on this specific model. It features 5120 SPUs as well as 320 Texture Address Units and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 120 Watts (67%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6900 XT should be 14% faster than the Radeon RX 5700 overall, due to its greater data rate. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon RX 5700		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT should be quite a bit (approximately 177%) faster with regards to texture filtering than the Radeon RX 5700. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 373040 (177%)

Pixel Rate

The Radeon RX 6900 XT is much (approximately 149%) better at full screen anti-aliasing than the Radeon RX 5700, and also will be able to handle higher screen resolutions better. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 139840 (149%)

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 max amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
