Объяснения неприятно неожиданных результатов:
"The most obvious culprits are:
Motherboard UEFI/bios.
Some reviewers mention a newer bios improve perf by a massive 25%. Computerbase mentioned that as well, and I trust those guys.
RAM usually does not have a major impact in most games. Like 2400 vs 2933, hardly any difference. Though some games like Fallout 4, do scale.
The other culprit that was confirmed by AMD reps & some reviewers, Windows Power management needs to be set on High Performance, not the default Balanced. On Balanced, Windows manages Ryzen's SenseMI and it does a bad job at it.
On High Perf, Ryzen manages itself and performance uplift was quoted at 5-15%. Since reviewers don't mention their Power settings with windows, we don't know their setting.
The ones that do mention they run on High Perf mode, like Joker & HardwareUnboxed, their results are very good overall.
There's also reports of Windows not knowing how to handle core parking with Ryzen yet, due to the 2x CCX (each 4 core) design, thread jumping from 1 CCX to the other has a heavy performance penalty. Basically, windows should not do that, keep everything within a CCX only. A windows update is needed to fix this."
Обновление БИОСа: +25%.
Кто-то писал о +17% в среднем прироста фпс-а.
Выставленный режим "Высокая производительность" в самой Windows +5...15%.
+ нужен апдейт самой Win, потому как она не знает, как нужно обращаться с 2-мя блоками CCX. Да и с SMT есть очевидные недоработки.

Игроделы также подтверждают, что оптимизация под Зен даст прирост:
"Oxide games is incredibly excited with what we are seeing from the Ryzen CPU.
Using our Nitrous game engine, we are working to scale our existing and future game title performance to take full advantage of Ryzen and its 8-core, 16-thread architecture, and the results thus far are impressive.
These optimizations are not yet available for Ryzen benchmarking.
However, expect updates soon to enhance the performance of games like Ashes of the Singularity on Ryzen CPUs, as well as our future game releases.” - Brad Wardell, CEO Stardock and Oxide
"Creative Assembly is committed to reviewing and optimizing its games on the all-new Ryzen CPU. While current third-party testing doesn’t reflect this yet, our joint optimization program with AMD means that we are looking at options to deliver performance optimization updates in the future to provide better performance on Ryzen CPUs moving forward. " – Creative Assembly, Developers of the Multi-award Winning Total War Series"
в итоге: как и предполагал, Зен не обошел ни Скай, ни Каби. Но кто этого ждал от него - это ваше завышенное ожидание и ваше же "разочарование".
Зен получился хорошим, но не лучшим (а если смотреть на стоимость данного камня (1700
329$ + разгон = 1800
499$), его перспективность, его отдачу для нас в виде супер-плавного геймплея - то вообще прекрасным).
з.ы. Ух, там еще 6- и 4- ядерные модели на подходе. Вот горения-то будут.
