With it's true eight cores, Zen accomplishes prowesses despite it's limited frequency of 3.3 Ghz. It's getting dangerously close - for Intel - of the Intel 6900K while offering performance comparable to the Core i7 5960X which has an identical frequency (3.3 Ghz in Turbo mode). AMD's allegations a few months ago seem to check out in practice, and this is an excellent news. Compared to the FX-8370, we witness a performance gain of around 35% for equal clockspeeds, matching there too with the manufacturer's previsions (40%)

If the results might seem clearly more disappointing on the average of the tested games, it fits to keep in mind than the tested prototype was an octo-core with a quite low frequency (in particular in Turbo mode). Meanwhile, the tested games stay very sensitive to the frequency and keep struggling to exploit more than four cores. Hard in those conditions to compare it with a Core i7 6700k of which frequency is at over 4 Ghz. Remains that the Zen architecture shows an efficiency we haven't saw at AMD since a very long time.
 Electric consumtion
Measures took at full load (in watts)
The measurement of the electric consumption of the Zen CPU was took with an amps meter on the ATX 12V connector at full load. While this method is less precise than the usual one we do on the oscilloscope, it gives a good idea of the performances of the 14 nm LPP of Global Foundries. Once removed losses from the motherboard's VRMs, we can estimate that the processor consumes a bit less than 90 W, a value very close to that of an 6900K. A result that gives good faith in the future.
The Zen architecture should allow ZEN to seriously come back on the CPU market, including the high-end segment abandoned since long. Intel thus risks to suffer a violent [untranslatable French gibberish], a well-deserved consequence for their years of lazyness and arrogance ( The 1 900€ core i7 6950X shall stay the perfect illustration of that). If we hope the comeback of a real concurrency on the processor market, all is not won yet for AMD. While the octocores look on schedule, the constructor must finalize quickly the quad-core derivatives with vastly higher frequencies than the current prototypes: 3.8 see 4.0 or 4.2 Ghz seems like the minimum to tickle the latest Kaby Lake. At last, remains a sizeable unknown : the prices. If some rumours talk of a prety low price grid, we doubt AMD will cut down their CPU while they at last have a chance to make up for their years of losses. At must, do not fuck up in the last straight line ...
