AMD Radeon Vega 20 References Spotted Lurking In Linux Driver Package

AMD is cooking up a new batch of Radeon Vega graphics cards for consumers, though most of the details remain a mystery. That said, there have been numerous roadmap leaks—as far back as a year and a half ago, there was a leaked roadmap that pointed to Vega 20 releasing some in 2018. Fast forward to today and there are some references to Vega 20 in recently released Linux drivers.

There is not a whole lot to go on here, just some call outs to Vega 20 in a Linux patch file. One thing that is interesting, however, is that there are half a dozen Vega 20 IDs. Here's a look at the text:

/* Vega 20 */
+ {0x1002, 0x66A0, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_VEGA20},
+ {0x1002, 0x66A1, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_VEGA20},
+ {0x1002, 0x66A2, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_VEGA20},
+ {0x1002, 0x66A3, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_VEGA20},
+ {0x1002, 0x66A7, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_VEGA20},
+ {0x1002, 0x66AF, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_VEGA20},

For comparison, Vega 10 has nine IDs, including Instinct, Radeon Pro, and the Radeon RX series. One thing we can extrapolate from this is that Vega 20 will potentially be built on a 7-nanometer FinFET manufacturer process. That is not to say it definitely will be, but it is possible that one of those IDs is a Radeon RX Vega on 7nm, which would indicate that AMD is least considering it.

Going back to September 2016, rumors at the time pointed to Vega having 64 Compute Units (CUs) and a whopping 32GB of second generation high bandwidth memory (HBM2), with 1TB/s of memory bandwidth. It was also said to boast support for PCI-Express 4.0 and have a TDP in the range of 150W to 300W.
