Radeon RX 470 4GB vs Radeon VII

Intro

Compare those specs to the Radeon VII, which has a core clock frequency of 1400 MHz and a HBM2 memory speed of 1000 MHz. It also features a 4096-bit bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 64 ROPs.

Radeon RX 470 4GB		120 Watts
Radeon VII		295 Watts
	Difference: 175 Watts (146%)

Memory Bandwidth

As far as performance goes, the Radeon VII should in theory be much better than the Radeon RX 470 4GB in general. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 837376 (396%)

Texel Rate

The Radeon VII will be much (approximately 183%) more effective at texture filtering than the Radeon RX 470 4GB. (explain)

Radeon VII		336000 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 217472 (183%)

Pixel Rate

The Radeon VII is quite a bit (more or less 202%) more effective at anti-aliasing than the Radeon RX 470 4GB, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon VII		89600 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 59968 (202%)

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 (counted in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
