  1. Due to the enermous number of requests we've been receiving since the Ryzen market launch, concerning various confusions about AIDA64 and Ryzen, hereby we post a clarification. AIDA64 is currently not 100% compatible with the recently unveiled AMD Ryzen high-performance x86 processors. It's because AIDA64 still has a few issues that we need to fix. However, in order to fix those issues, we first need to run a series of very long benchmark tests on Ryzen, and that -- among with the bug fixes themselves -- will take several days to complete. As for the bugs and limitations we so far discovered: UPDATE: We have fixed #3, #4, #5 and #7 in the latest AIDA64 v5.90.4200 stable update, which is now 100% compatible with AMD Ryzen processors: https://www.aida64.com/downloads/latesta64xe 1) A number of minor hardware detection issues were already fixed in the latest AIDA64 beta update. 2) The list of Turbo and XFR PStates are invisible on Ryzen, so it's not possible to properly enumerate or track them using a software. When a core of the AMD Ryzen processor goes into idle, the core will report the clockspeed of the P2 power state (e.g. 2200MHz on the Ryzen 7 1800X) and enter into the core-c1 (CC1) or core-c6 (CC6) sleep state. While the VID remains detectable in these states, the states are power gated and the true frequency is not known to the OS or monitoring utilities. As indicated from the “fine-grained Pstate” commentary released at Ryzen Tech Day, the AMD Ryzen’s processor true frequencies in these modes are significantly lower than reported via the “last known” P2 reading. AMD engineering tells us that V/f changes can be executed at 1ms intervals, indicating that the act of monitoring the states with the resolution necessary to accurately capture this behavior would also prevent cores from entering into the ultra low-power CC1 or CC6 states. 3) L1 cache bandwidth and latency scores, as well as memory bandwidth and latency scores are already accurately measured. 4) L2 cache and L3 cache scores indicate a lower performance than the peak performance of Ryzen. The scores AIDA64 measure are actually not incorrect, they just show the average performance of the L2 and L3 caches rather than the peak performance. It will of course be fixed soon. 5) Even though AIDA64 warns about a potential lack of optimization, the CPU and FPU benchmarks should be indicative of the full potential of Ryzen. We may be able to tweak e.g. the FPU Julia benchmark to squeeze even more performance out of Ryzen, but we don't expect the improvement to be substantial. 6) The CPU Hash benchmark provides an exceptionally great score on Ryzen due to the hardware accelerated SHA instructions capability of Ryzen. It's absolutely normal that hardware acceleration boosts CPU computing performance by such a margin. 7) AM4 motherboards are not yet supported by the latest AIDA64 stable build of v5.80.4000. Make sure to use the latest AIDA64 beta build to have accurate sensor measurements on ASRock, Asus, Biostar, Gigabyte, and MSI AM4 motherboards. We will post further updates to this topic as we progress with our bug fixing efforts on our Ryzen test systems.
