AMD Tonga XT Blueprints Surface - Has HSA Support, 384 Bit Bus and 2048 SPs

The Tech Publication PC Watch recently published documents and revealed some facts about the AMD Tonga XT GPU. These were then verified by Videocardz.com, who in turn revealed more than about the same. This combo has confirmed the original leak that nosotros published some days ago while adding more data on peak of it.

AMD's Full Fatty Tonga XT has 2048 Stream Processors with a 384 Bit Bus and HSA Support

AMD' due south Tonga is a very interesting product. It received a very mild reception and was, in my stance, mistimed and wrongly portrayed. The Tonga XT has 256 more shader count than the Tonga PRO GPU, which means that AMD is using the historic period old tactic of holding the practiced stuff back till information technology is actually needed. The full fat Tonga XT packs a total of 32 compute unit and 6 memory controllers. Since each is 64 bits wide, it adds upward to a 384 bit interface.

Interestingly the GPU supports HSA and GCN i.1. The configuration is similar to Tahiti. We don't accept any specifics regarding the clock speeds,  but 918 MHz is the reference clock for Radeon R9 285 and then we can expect something around 933-1000 MHz for the Tonga XT variant. It is a scrap weird that the Radeon R9 285X is featuring a 384-chip retentiveness motorbus compared to 256-flake bus on its Pro variant only this news is now more or less confirmed. Allegedly, Tonga XT will exist shifting to a higher VRAM of 3GB GDDR5.

The Radeon R9 285 is already considered a mid-tier board from its looks and blueprint but the Radeon R9 285X could be a decent update over Radeon R9 280X. Existence like to Tahiti in board design only the updated core with new architecture will leverage the performance and while the Tahiti XT variants have a TDP of 250W, we tin can might 200W TDP for Tonga XT variants which arrive in September. The pricing for the Radeon R9 285 could fall in between $250 Usa while the Radeon R9 285X could retail at $300 U.s.a..
