The AMD Zen 2 processor design has been entrance and centre at in the present day’s Next Horizon occasion. While it’s ostensibly a datacentre-focused occasion, the corporate has uncovered some fascinating new design factors relating to the upcoming Zen 2 CPU structure, together with its “revolutionary chiplet design.” The occasion has coated what the Zen 2 EPYC server chips will appear like, nevertheless it follows that the patron design will seemingly observe swimsuit.
AMD has re-confirmed that the Zen 2 silicon will arrive subsequent 12 months, and that it’s going to include a brand new, distinctive multi-chip chip design. That means it is going to home each 7nm and 14nm silicon – with “each IP in its optimal technology” – so it’s not simply utilizing 7nm chips for the sake of it. The Zen 2 CPU chiplets themselves can be constructed on the brand new TSMC 7nm course of node, however the I/O die, the half that handles all of the inputs and outputs for the processor silicon, can be constructed utilizing the present, steady 14nm lithography.
AMD has previously spoken about using chiplets, and, after all, AMD’s Inifinity Fabric can be used to attach all of it collectively and guarantee this modularity doesn’t come at the price of both latency or general efficiency.
AMD has additionally spoken concerning the improved efficiency of the Zen 2 structure, with the brand new design reportedly providing double the throughput, with new entrance finish advances, floating level advances, and a doubling of the core density.
We’ve heard lots of discuss previous to the Next Horizon occasion concerning the IPC enhancements round Zen 2, however that is the primary concrete proof about what’s going to drive that additional efficiency. There’s additionally tacit affirmation that there’s the potential for a ridiculous variety of cores to be dropped into the subsequent era of AMD desktop processors too.
Sure, the doubled core density declare is made relating to the datacentre CPUs, however the modular design has been used to make sure scalability of the Zen structure from the highest to the underside of its stack, so it’s not wild hypothesis to assume AMD will sing from the identical hymn guide this time round. Therefore we could be fairly assured there’s an entire lot of processor coming into play with AMD CPUs in 2019.
And not solely does the Zen 2 design supply additional cores, however the 7nm manufacturing course of and the brand new chiplet structure means will probably be dropping the facility calls for too. AMD is promising half the vitality per operation, which ought to permit it to considerably up the bottom and increase frequencies of its processors too.
But AMD isn’t stopping there, it additionally took time no give a nod to Zen 3, on the 7nm+ node, saying that’s ‘on track’ and that the Zen four structure was already ‘in design.’ AMD’s momentum appears to be rolling alongside properly and if the datacentre design interprets all the way down to the desktop in the identical approach as Zen has achieved, then it’s going to take a Herculean effort for Intel to stay aggressive.
