It’s no secret that AMD has been having quite a bad time in recent years in the CPU market, as their new architectures have been unable to compete well with Intel, in terms of performance or consumption, and the company has invested much of its efforts to its non-expensive APUs with integrated graphics.

To try to recover lost ground, AMD is preparing a new architecture that will abandon the shared core systems that was implemented in Bulldozer architectures (with semi-independent cores with part of their shared resources with other nuclei) to opt for a monolithic architecture similar to what we saw in the Phenom models a few years ago under the name ZEN architecture.

AMD ZEN

Thus, each core will have its own resources (each core will have 512KB of L2 cache) and communicate via L3 cache that will share all the cores from the package. ZEN will allow 4 core independent units to run under the same 8MB L3 cache. So with just a single unit 4-core processors may only be created. However, we may see combinations of several units to create multi-core processors in a single package.

The new chips will support DDR3 and the new DDR4, as well as PCI Express 3.0, and will be manufactured according to a 14 nanometers standard, in which Globalfoundries is working.

AMD ZEN

Now we can only wait until 2016, the expected arrival date of the processors based on this ZEN architecture and see if it AMD finally returns to compete with Intel as equals, just like the time of the first Athlon processors.
