AMD Launches RDNA [GPU] Macro Architecture: PCIe 4.0, 1.25x IPC And 1.5x Performance Per Watt Upgrade Over GCN

Most interestingly .. it features a completely new compute unit design.

This results in reduced latency, higher bandwidth availability ( on a per-core basis) and lower power consumption.

The RDNA macro-architecture also features streamlined graphics pipeline which features “high clock speed”. ...If this is true then we should be seeing some pretty big performance gains.

Finally, here is the kicker, RDNA fully supports PCIe 4.0 which means NAVI GPU is slated to be the first PCIe 4.0 gaming GPU in the world. This is great news because it means the company is looking to future proof its lineup for the get go – something its known for and has a considerable amount of goodwill for,
