Radeon RX 5700 XT vs Radeon VII

Intro

Compare all that to the Radeon VII, which features clock speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 memory. It features 3840 SPUs as well as 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

Performance-wise, the Radeon VII should theoretically be much superior to 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 is a lot (about 31%) faster with regards to AF than the Radeon RX 5700 XT. (explain)

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

Pixel Rate

The Radeon RX 5700 XT is just a bit (more or less 15%) more effective at FSAA than the Radeon VII, and also able to handle higher screen resolutions more effectively. (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 largest amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units 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 applied in one second.

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