Benchmarks and a review of AMD's Ryzen 8 core CPU have leaked ahead of the official release date, thanks to the French magazine CPC (Canard PC). These benchmarks pit the Ryzen processor (which is an engineering sample) against several of Intel's own CPU's and also against the previous FX series.

Do note that these tests are from an Engineering sample that has lower clock speeds than AMD's retail versions. The Engineering samplewas clocked at 3.15GHz, with a boost/turbo clock speed of 3.3GHz on all cores and a maximum turbo boost of 3.5GHz on a single CPU core. The retail version of AMD's Ryzen will be clocked at 3.4Ghz so we expect an additional 8% performance boost (assuming that the boost/turbo clocks get a similar increase).
