AMD’s upcoming Tonga GPU is a name that you should have heard of by now. New details about the GPU have been revealed. The first and most important news is that the GPU is slated to be released sometime in August. The GPU will replace the Tahiti PRO GPU (R9 280) for the mid-range spectrum. The performance of the chip is supposed to be between the Tahiti PRO and Tahiti XT GPUs.
Tonga is said to have 32 Compute Units, which means 2048 stream cores. The Tonga will feature 2 GB of GDDR5 memory and a 256-bit interface.
It is currently unknown if that card will be named under the R9 280 or R9 270 series. Tonga could possibly be the first GPU manufactured by Global Foundries and is expected to more power efficient and less power hungry.
