Radeon RX 470 4GB vs Radeon VII

Intro

Compare that to the Radeon VII, which features a GPU core clock speed of 1400 MHz, and 16384 MB of HBM2 memory running at 1000 MHz through a 4096-bit bus. It also is made up of 3840 SPUs, 240 TAUs, and 64 ROPs.

Texel Rate

The Radeon VII should be a lot (more or less 183%) better at AF 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 will be quite a bit (more or less 202%) faster with regards to full screen anti-aliasing than the Radeon RX 470 4GB, and should be capable of handling higher resolutions more effectively. (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 maximum amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
