AMD might possibly be delaying their next generation of Kaveri APUs due to late manufacturing and availability of retail samples as reported by Digitimes. According to them, AMD's Kaveri APUs won't reach mass production by the end of 2013 which means that their retail availability could be delayed until 2014. You can check out the complete architecture details on Kaveri APU here.
AMD Kaveri APUs Retail Supply Possibly Delayed to Q1 2014
AMD's Kaveri APU were originally scheduled for launch in Q4 2013 with the arrival of the new A-Series desktop APUs that would feature an x86 Steamroller core architecture along with the latest GCN graphics die. A major feature to be implemented in the Kaveri APUs is the HUMA memory architecture which is part of HSA (Heterogeneous System Architecture) which would allow PCs to make use of a unified memory architecture which would allow cross sharing of system ram between the GPU and CPU. This would enhance the way PCs access and communicate with their memory. This would pit the launch of Kaveri APUs close to the AMD Berlin server APU that's specifically the same thing aimed towards the enterprise markets while Kaveri APUs would ship to consumers.
It is expected that AMD would only provide two A10 and one A8 Kaveri APUs samples to its channel partners in Decemeber 2013 which would make it quiet difficult for AMD to provide retail channels with Kaveri APUs until February - April 2014.
AMD Kaveri APU platform would launch with the AMD A88X “Bolton D4″ and A87X chipsets on the socket FM2+ motherboards. The socket FM2+ would be backwards compatible with both Richland and Trinity APUs which is a plus point but Kaveri won’t operate on the FM2 motherboards due to different pin layout. Kaveri would launch in Dual and Quad core steamroller SKUs with GCN enabled integrated graphics processors. Desktop models would range between 100 and 65W TDPs while mobility models would have 35W TDP and even lower for specific APUs.
