Online sources that deal with hardware news have posted some rather intriguing information that deals with the current crop of AMD Radeon R9 280 and R9 280X graphics cards. If the information is correct then AMD will soon update these graphics solutions with a more efficient GPU codenamed Tonga.
The tech specs of the new Radeon R9 280X and R9 280 graphics cards remain unknown although the information suggests that there will be a frame buffer cut. Thus if you happen to get one of these (if they come into existence after all) expect to find just 2 GB of GDDR5 memory, down from the 3 GB most R9 280X and R9 280 graphics cards come with. As to the GPU it will likely be built on 20 nm technology and given its architectural improvements it will probably need a lot less power but do not expect performance gains as it makes no sense to make a card with the same name but with more power.
The pricing of the new cards is also a mystery as of now. They are expected in mid-August so we’ll have more information by then but given the GDDR memory cut they may be a bit cheaper than the current R9 280 and R9 280X generations.
