Respectively, the Tonga GPU is somehow a latest version of 380, the first of the GCN family that is compatible with the Radeon HD 7970, Radeon HD 7970 GHz Edition is now renamed as Radeon R9 280X. So, this Radeon R9 380x can purly seen as the updated verison of the Radeon HD 7970.

Tonga has got the remarks of 2048 processing units, such as Tahiti, but supports all the latest developments of small architecture that provide good performance and new features (FreeSync, TrueAudio, CrossFire XDMA, D3D 12_0 ) Initially, the Radeon R9 285, AMD has yet merely configure Tonga with 1792 active computing units and thereafter, the R9 380 has almost the same configuration.

The Radeon R9 380x finally goes into high gear with all 2048 active computing units. By configue, like previous derivatives, it is satisfied with a 256-bit memory bus, where Tahiti enjoys a 384-bit bus. AMD is not very clear on this point, we do not know if it is the maximum support by Tonga or configuration choices of the chip.

Sapphire keeps the 380X’s Tonga chip cool with one of its attractive Dual-X heat-sinks. This cooler’s twin ball-bearing fans can stop spinning under light loads for silent operation. From this angle, you can see this card’s numerous copper heat pipes, too.
