8.1 Out of 10

Clearly the newer architecture has allowed AMD engineers to spend some time tweaking the organization of the Compute Units in a way to improve overall efficiency.

This suggests that the Tonga GPU is highly efficient and AMD took this approach due to NVIDIA’s recent Kepler launches which turned out to deliver great performance at absolute low TDPs of 65W (GeForce GTX 750 series).

NVIDIA has no plans to introduce a dual Maxwell chip this early but they are planning to stir up the professional market with the Tesla K80 graphics card which is a dual GK110 based card, similar to the Titan Z in terms of design. The overall specifications did result in a TDP increase from 195W to 230 (GeForce GTX 680 vs GeForce GTX 770) but it meant better performance and overclocking potential since the card did make use of a better reference PCB.

It is great to see that this $249 GPU can handle Bioshock Infinite at 2560x1440 over 60 FPS on average. The only outward sign that we are dealing with a new piece of silicon is the lack of any CrossFire connections.

What is pretty sure now is that we are looking at Tonga Pro GPU which will have a 256-bit memory interface connected to 2GB of GDDR5 memory (although some partners might make a 4GB version as well). Sapphire's pictured R9 285 will feature Sapphire's Dual-X dual-fan cooler and will use the design which we already seen on some of the earlier Sapphire graphics cards, and same will most likely go for all other AMD AIB partners.
This suggests that the Tonga GPU is highly efficient and AMD took this approach due to NVIDIA’s recent Kepler launches which turned out to deliver great performance at absolute low TDPs of 65W (GeForce GTX 750 series). Videocardz has popped the lid on AMD’s upcoming Radeon R9 285 graphics card and leaked a couple of them from various AIBs.
