The new APU will replace the Godaveri platform which we were introduced to with the Carrizo APU, with the Carizzo-based notebooks arriving in the next couple of months, but most likely at Computex 2015 in June. The new Zen APU would feature quad-channel DDR4 support, up to 16 processor cores based on the Zen architecture, and the HBM-powered Greenland GPU.
