Radeon RX 470 vs Radeon VII

Intro

Compare all that to the Radeon VII, which uses a 7 nm design. AMD has set the core speed at 1400 MHz. The HBM2 memory works at a speed of 1000 MHz on this model. It features 3840 SPUs along with 240 TAUs and 64 ROPs.

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

Pixel Rate

The Radeon VII will be quite a bit (approximately 202%) better at anti-aliasing than the Radeon RX 470, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon VII		89600 Mpixels/sec
Radeon RX 470		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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
