Napravili su, ali PR "rebrandeon" je cool medju tinejžerima, pa se "vrti po internetu". 380 je 285 (GCN1,2) ne 280 (GCN1,0)
The final die size of Tonga is 359mm2 and it packs an unexpectedly high 5 billion transistors. Compared to Tahiti, this is a very slight (7mm2) increase in die size, while the transistor count has gone up by nearly 700M from Tahiti’s 4.31B transistors. Tonga’s configuration and die size indicate that AMD has made some interesting tradeoffs in terms of die size and features. The narrower memory bus means that AMD was able to drop a pair of memory controllers and the memory crossbar, only for AMD to fill it in with the additional transistors needed to drive all of the additional features (and geometry processors) that Tahiti lacked.
