Radeon RX 470 4GB vs Radeon VII

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon VII should perform much faster 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 should be a lot (approximately 183%) more effective at anisotropic 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

If using high levels of AA is important to you, then the Radeon VII is a better choice, and very much so. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
