AMD To Replace Radeon R9 280 GPU With Tonga

Chinese VR Zone revealed that AMD will replace its Radeon R9 280's Tahiti PRO GPU with Tonga GPU starting sometime in August.

Radeon R9 280 is AMD's current mid-range graphics card. Little is known yet about Tonga, but rumors in the industry have it that it should sport a 256bit interface that has 32 Compute Uitss and 2048 Stream processors. The GPU should also feature 32 ROPs (Render Output Units) and 128 Texture memory units.

AMD's R9 series is based on the company's GCN (Graphics Core Next) architecture and Tonga is meant to introduce GCN 2 to the market. It is built on the 28nm node from Global Foundries. GCN 2 (and Tonga) keeps all standard AMD Radeon technologies such as Mantle, TrueAudio and XDMA for CrossFire support. The chipset's main focus is said to be power efficiency.
