Vega 20 should be ~13.8 TFLOPs (single precision): https://www.anandtech.com/show/13923/the-amd-radeon-vii-revi...

Seems like AMD has been using Vega 20 to refer to two different things.

I was talking about the mobile GPU on MacBook Pros which is based on a 14nm chip. The full name is Radeon Pro Vega 20:

Vega 20 seems to also refer to a discrete GPU. This has been later rebranded to Radeon VII (maybe because of this confusion). The number you are quoting is for the discrete GPU.

Huh, I had no idea they used Vega 20 both as a codename and a product name. Confusing.

Same with 10 LOL. VEGA10 codename is for the original Vega Frontier Edition/RX Vega 56/RX Vega 64. But now there's also "Vega 10" used as a description for the 10 Vega compute units on Ryzen APUs.
