AMD has finally published additional performance figures for Zen beyond the 40% IPC improvement over excavator that the company talked about last year. The 40% IPC uplift figure represents the architectural performance per clock improvement of Zen vs AMD’s last CPU architecture, code named Excavator. And while comparing the architectural capabilities of Zen to Excavator may have been informative, it doesn’t offer a direct real-world product to product comparison. Thankfully, we do finally have direct real-world performance figures for Zen.
Compared to AMD’s “Orochi” quad module, eight core die powering the FX 8350, the Zen based desktop Summit Ridge eight core CPU delivers double the performance in Cinebench R15. This means that a single Zen core is in effect equivalent to two Piledriver cores in performance, which is incredibly impressive. This dramatic performance difference comes from the significant architectural performance per clock improvements in addition to Zen’s simultaneous multithreading capability.
it’s important to remember that AMD’s latest Orochi dies feature Piledriver cores rather than Excavator. Excavator cores are roughly 15% faster per clock than Piledriver This in turn puts Zen at a lead in excess of 60% vs Piledriver in terms of performance per clock. Doubling the performance of the FX 8350 puts Zen in direct competition with Intel’s eight core i7 5960X.
