Radeon RX 5700 XT vs Radeon VII

Intro

The Radeon RX 5700 XT makes use of a 7 nm design. AMD has clocked the core speed at 1605 MHz. The GDDR6 memory works at a speed of 1750 MHz on this card. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Compare that to the Radeon VII, which has clock speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 memory. It features 3840 SPUs along with 240 Texture Address Units and 64 ROPs.

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

The Radeon VII should theoretically perform quite a bit faster than the Radeon RX 5700 XT in general. (explain)

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

Texel Rate

The Radeon VII will be a lot (approximately 31%) faster with regards to 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 running with a high screen resolution is important to you, then the Radeon RX 5700 XT is a better choice, but not by far. (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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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 max fill rate.
