Even though AMD's next-generation Kaveri APU, based on the Steamroller x86 CPU, GCN (Graphics Core Next) GPU, and HUMA memory architecture might not arrive until late in 1H of 2014, its successor is already named and being worked on by AMD. Carizo, successor to Kaveri, will arrive sometime in 2015, we are betting before the end of 1H 2015, and will feature further improvements in AMD's big APU push. While nothing is confirmed, Carizo most probably packs AMD's next-in-line Excavator CPU core and perhaps an improved GCN based GPU core. Memory architecture will undoubtedly feature further improvements, in line with AMD's big push for heterogeneous computing and unified memory. "In the first half of 2014, AMD plans to release two more HSA-based APU series: Berlin for server products and Beema, to replace the existing Kabini APU series. In 2015, AMD will release Carizo and Nolan APU series to replace Kaveri and Beema, respectively, both featuring HSA." There's no word on the manufacturing process, but AMD may move on to a smaller 20nm node by then, only to compete with Intel's 14nm Skylake platform.
