TPU writes AMD is expected to introduce the 28nm Tonga GPU in August. This new graphics card is reportedly designed to take on NVIDIA's bestselling GeForce GTX 760. Tonga is anticipated to offer performance similar to the Radeon R9 280 but with a new mix of components that should not only reduce power draw but also overall costs.
The 28 nm "Tonga" silicon is expected to feature 2,048 GCN2 stream processors, 128 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface. You'll notice that its memory interface is narrower than that of the R9 280, but performance is made up for with a higher stream processor count, and probably higher clock speeds, too. The card could come in memory capacities of 2 GB, with some manufacturers innovating 4 GB variants. There's no word on what the company could end up naming the first cards running this chip.
