Radeon RX 590 vs Radeon VII

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
Radeon VII		295 Watts
	Difference: 120 Watts (69%)

Memory Bandwidth

Performance-wise, the Radeon VII should theoretically be much superior to the Radeon RX 590 overall. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 786432 (300%)

Texel Rate

The Radeon VII should be a lot (about 59%) more effective at texture filtering than the Radeon RX 590. (explain)

Radeon VII		336000 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 124464 (59%)

Pixel Rate

The Radeon VII should be a lot (approximately 91%) better at FSAA than the Radeon RX 590, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon VII		89600 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 42592 (91%)

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 (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 card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
