Let me first state that the release date is a rumor that popped up over the weekend, not a fact. According to sources at HardwareBattle, AMD is to launch the Dual FIJI GPUs based Radeon Pro Duo in roughly three weeks time. AMD recently announced the product on its Capsaicin-event at GDC 2016.
The Radeon Duo Pro with its two FIJI GPUs are tied towards a thick 120mm liquid cooling solution. The product will offer 16 teraflops of performance, indicating two fully enabled Fiji XT GPUs. AMD Radeon Pro Duo (dual-GPU Fiji) was developed under code-name Gemini would have 8 GB HBM1 graphics memory with a whopping 8192 stream processors.
The specs below are not final yet based up-on assumptions (they should be pretty conclusive though). The AMD Radeon Pro Duo is expected to sell at a SEP of $1499 USD.
