Radeon RX 5700 XT vs Radeon VII

Intro

Compare all that to the Radeon VII, which makes use of a 7 nm design. AMD has clocked the core frequency at 1400 MHz. The HBM2 memory is set to run at a frequency of 1000 MHz on this particular card. It features 3840 SPUs along with 240 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT		225 Watts
Radeon VII		295 Watts
	Difference: 70 Watts (31%)

Memory Bandwidth

Theoretically, the Radeon VII should perform much faster than the Radeon RX 5700 XT overall. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 5700 XT		458752 MB/sec
	Difference: 589824 (129%)

Texel Rate

The Radeon VII should be much (more or less 31%) more effective at anisotropic filtering than the Radeon RX 5700 XT. (explain)

Radeon VII		336000 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 79200 (31%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5700 XT is the winner, not by a very large margin though. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 13120 (15%)

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 (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
