TweakTown spreads news about rumors that AMD's future Radeon R9 390X graphics card will be made on a 20nm process.
Expected to be released in the first half of 2015, the chip will reportedly come with High Bandwidth Memory (HBM), a new type of 3D stacked memory that promises a significant bandwidth increase versus GDDR5 memory. Additionally, it's also rumored that the R9 390X may feature a Hydra watercooling solution.
The only bummer perhaps is that the Radeon R9 390X isn't likely to come out before Q2 2015 which means AMD has little to offer for the next couple of months except perhaps another round of price cuts to maintain its marketshare in the high-end market.
The new Radeon R9 390X is based on AMD's Bermuda GPU core, which should kick some serious ass, bringing a slew of new things to AMD's silicon. First off, we should see the R9 390X being the first GPU to be built on TSMC's new 20nm manufacturing process, but the card is rumored to arrive with High Bandwidth Memory, or HBM. HBM is 3D stacked memory technology that will offer an incredible amount of bandwidth on the already-fast GDDR5 tech that is used, with around 100% more bandwidth, all while using less power.
