AMD VEGA10 and VEGA20 details leak, NAVI delayed to 2019

A couple of tidbits about AMD's future Vega and Navi GPU architectures were published over at VideoCardz. The details below originate from an internal AMD server roadmap and were reportedly leaked by the same source that confirmed the mobile Polaris specifications weeks before it was released. VideoCardz delivers a lot of reliable video card leaks but some of the information in their most recent post makes us scratch our heads.

AMD Vega 10 expected in Q1 2017, dual-Vega in Q2 2017
First up we have the Vega 10, this will be the next high-end GPU architecture from AMD and it's expected to be available in retail stores in Q1 2017.

Made on a 14nm FinFET process, the Vega 10 chips will be part of the GFX9 architecture and reportedly feature 64 compute units and a raw computing power (16-bits) of 24 teraflops. The card comes with 16GB HBM2 with a bandwidth of 512Gbps and the total board power (TBP) is anticipated to be around 225W. For comparison, the NVIDIA GP100 offers just over 21 teraflops of FP16 computing power.

A dual-GPU Vega 10 is expected to follow in the second quarter of 2017, this model allegedly has a TBP of around 300W.

AMD Vega 20 on a 7nm process?!
The Vega 20 reportedly has the same 150W TBP and 64 compute units as the Vega 10, but 32GB HBM2 with a memory bandwidth of 1TB/s. This card is expected to feature PCI Express 4.0, which is plausible, but where it gets really weird is the claim that Vega 20 will be a 7nm shrink of the GFX9 architecture.

The article makes no mention of a launch timeframe but 7nm GPUs aren't plausible anytime soon considering GlobalFoundries said last week they expect to begin 7nm risk production in 2018. This means commercial parts won't arrive until late 2018 at the earliest, and probably not before 2019.

AMD Vega 11 to replace Polaris 10 in 2017
A replacement for the Polaris 10 (aka Radeon RX 480) is expected in 2017 in the form of the Vega 11 series. Not a lot of details are known but presumably it's made on a 14nm FinFET process.

AMD Navi delayed to 2019?
One last rumor is that the Navi 10 and Navi 11 GPUs are delayed one year to the 2019 timeframe. So if this rumor is correct, AMD's 2018 GPU lineup may be very empty. We don't know a lot about Navi, one of the few things AMD shared about it is that it will use a next-gen memory technology.
