A Closer Look At AMD GPU Architecture Roadmap: Vega 10, Dual Vega 10, Vega 11 & Vega 20

By Jeff Harris, Posted: 11/28/16 05:00AM EST

Talks about AMD's upcoming graphics card "Radeon RX 490" have been making waves for quite some time now. Perhaps it's because of the fact that many tech analysts see this GPU as even more powerful than NVIDIA's "GeForce GTX 1080" and even "Titan X."

While there are still debates whether "Radeon RX 490" is the first GPU under AMD's upcoming Vega architecture or the last hoorah of Polaris being Dual Polaris 10 remains to be seen. But the fact remains - AMD will soon release its Vega architecture which is based on the second generation High Bandwidth Memory (HBM2) technology.

People may now be familiar with Vega 10, supposedly the architecture where "Radeon RX 490" falls under. And like Polaris, Vega has a different set of codenames. But unlike Polaris, Vega has four sets: Vega 10, Dual Vega 10, Vega 11 and Vega 20.

Vega 10 Specifications

During last August's Investor Presentation, AMD revealed that they expect to launch "Vega for the 'enthusiast market' in 1H 2017". It's important to note that AMD specifically mentioned 'enthusiast market'. A few weeks later in an exclusive report from VideoCardz.com, new information revealed that Vega 10 is set for release by the first quarter of 2017.

Based on the initial reports, Vega 10 will be based on 14nm GFX9 architecture (Polaris is GFX8) which has 64 Compute Units and 24TF 16-bit computing power. Vega 10 is said to have two stacks of HBM2, thus, it will have at least 16GB of HBM2 memory. The bandwidth is set to reach 512 GB/s while TBP is expected at 225W.

Other Vega Architectures

The Dual Vega 10 is expected to be released sometime during the second quarter of 2017. Based on the name alone, of course, everything is double the Vega 10 architecture as recently posted on VideoCardz.com, with the exception of TBP which is set at 300W. Four stacks of HBM2 which could reach up to 32GB of memory, 1TB/s memory bandwidth, and 2x64 Compute Units.

Vega 20is a bit strange considering earlier rumors suggest this graphics card's features will play somewhere in between Vega 10 and Dual Vega 10 which would mean there's no 64GB memory yet. However, one thing's to look forward to - 7nm GFX9.

Meanwhile, AMD is still mum about Vega 11. The only information available on Vega 11 is the same architecture as Vega 10 which is 14nm GFX9, PCI-E 3.0 interface and that it is said to replace Polaris 10 in the 'professional market', not on the 'enthusiasts market'.
