AMD Unveils Zen cores and deletes x86 ARM project




AMD has released details about the next generation of Zen cores. In addition, the company pulls the plug Skybridge project, which the manufacturer x86 APUs wanted to combine with ARM cores. Furthermore, AMD confirmed the advent of graphics cards with high memory bandwidth.

Zen is the new architecture for high-end processors in AMD’s FX line, equipped with the new cores in 2016. It is a completely new design which will ensure that 40 percent more instructions per clock tick can be handled than the current Excavator cores can. The throughput should increase considerably by what AMD calls Simultaneous Multithreading, which roughly equates to what Intel’s HyperThreading.

AMD FX processors with Zen-cores have the AM4 platform with the next generation desktop APUs in the A series will share and two chip generations should appear in 2016. The chips will be built on a FinFET-process, which will bring benefits in terms of efficiency itself.

The unveiling of the Zen architecture happened one analyst presentation in which the future of AMD were explained in detail. AMD will invest less in low-end PCs, tablets and smartphones and more on gaming, data centers and embedded chips and custom targeting.

The development of ARM cores remains on the roadmap, but Project Skybridge must step down. For this project wanted to AMD ARM A57 cores combine with Puma + -cores and a GCN GPU but based on feedback from the market scrapped the plans, said AMD CEO Lisa Su.

Finally, AMD confirmed that upcoming graphics cards with high bandwidth memory equipped to go. Rumors about doing the long round. The accompanying graph shows that it is a so-called 2,5- and not “pure” 3D method is: the dram layers are stacked next to the processor and not on it. The dram-layers are connected to each other, and an interposer via vertical through-silicon via – or TSV-channels, which rest on a base layer. Tsv constitute paths through the silicon, as the name implies, and hence provide short lines. According to AMD goes hbm compared gddr5 for a tripling of the performance-per-watt and decrease in consumption of 50 per cent worry. Details on the cards will be equipped with hbm AMD did not.
