Latest leaks from AMD’s GPUOpen announcement presentation indicate that the AMD’s 4th generation GCN architecture will be called Polaris, Which promises greater efficiency.
Polaris Is The AMD’s 4Th Generation GPU Architecture
Introducing the Polaris Architecture
Our guiding lights is to power every pixel on every device efficiently. Stars are the most efficient photon generators of our universe. Their efficiency is the inspiration for every pixel we generate.
AMD’s next-Generation GPUs will be manufactured on the Polaris and this new architecture is manufactured by Samsung to a lithography 14nm FinFET LPP. Grip of Samsung on this process node is at a mature stage as a company is already selling its SoCs and also manufacturing for Apple SoCs. So we can say that this move will give the tough fight to NVIDIA Pascal GPUs manufactured on 16nm FinFET.
The new architecture will be twice as fast in comparison with Fiji and support second generation of High-Bandwidth Memory (HBM2), which is also manufactured by Samsung. While HBM1 memory has a physical limitation of up to 4 GB of capacity and a bandwidth of 512 GB / s, HBM2 memory allows the use of up to 16/32 GB of VRAM that can exceed 1024 GB / s.
