AMD Claims Zen 2 Has 29% Higher IPC than Zen 1 in Certain Workloads

Notebookcheck is pointing out that AMD had quietly disclosed some information on Zen 2's IPC deep within the footnotes of their Rome announcement: the company is claiming a 29% increase in IPC when comparing Zen 2 to Zen 1 in "combined floating point and integer benchmarks." The author calls this "decently high," as "AMD achieved a 52% IPC uplift when comparing Zen to Piledriver." Of course, don't take AMD's word for granted, the IPC increase in reality may be slightly lower in floating point and integer workloads and it could be much lower in other workloads that do not utilize the FPU. FLOPs are important for the data center, so it makes sense AMD would have improved the ability of Zen to push those FLOPs. This may not translate to additional performance for games, web browsing, video encoding, and other common usages for CPUs that exist within the professional and consumer spaces.
