The excluded workloads are: Embree, Variable Density Fluid Simulation, Linpack, NBody & X265 for Coffee Lake and Skylake-X. >=256b” means that workloads, which gain a significant advantage from wider than 128-bit instructions have been excluded from the total value. The extremities are: 3DPM (Low) & WinRAR (High) for Pinnacle Ridge, GCC (Low) & NBody (High) for Coffee Lake, GCC (Low) & Linpack (High) for Skylake-X. In this category the single smallest and the largest difference have been excluded from the total value. ASUS Rampage VI Apex (bios 1102 w/ final Spectre ♜ode 0x2000043 patched in).ASUS PRIME Z370-A (bios 0607 / 0613 w/ final Spectre ♜ode 0x84 patched in).ASUS Crosshair VI Hero (bios 6001, PinnaclePI 1.0.0.0a).All public and self-compiled workload binaries using Intel compiler have been patched in order to disable CPU vendor dependent dispatching. The testing was conducted using the latest versions of the applications (at the time of testing, Feb-Apr 2018). The performance of Pinnacle Ridge was compared against its predecessor and competing Intel designs, using freshly updated and slightly revised test suite. In certain latency sensitive workloads (such as WinRAR) the difference can be as high as 8% in favor of Pinnacle Ridge, confirming said changes to the caches and the slightly improved memory latency.
On average Pinnacle Ridge provides ~1.5% higher IPC than its predecessor.

The rest of the changes featured in Pinnacle Ridge are related to manufacturing process, the scalable data fabric (SDF, "IF"), the memory controller and firmware / software configuration of various domains and components. The biggest Zen-core related change compared to Summit Ridge is the L2 cache latency, which has been reduced from 17 CLKs to 12 CLKs. The Zen-cores inside Pinnacle Ridge have undergone the same changes, which were originally introduced in Raven Ridge APUs earlier this year. Consider this as a test report, rather than an actual review.
