Some tech bloggers/vloggers/tubers consider WCCFTECH to be a tech tabloid publication, but in my experience they've been right or very close to the truth most of the time. In this case, the timeline makes sense, as the mainboards (and some CPUs too) for the new AMD platform are already shipping to warehouses around the world. WCCFTECH has published retail box art, as well as photos with the review sample processors.
This also means that a couple of these chips will surely be available on the black market, possibly for thousands of dollars ... after the the official launch and with worldwide availability, review samples usually lose their value, as they don't benefit of any warranty, nor long term BIOS support. My advice is not to fall for these shady sellers and wait for the official Retail product on amazon.com.
AMD and Intel fanboys are already arguing about leaked test results, which aren't very clear about which one is the winner. The tests are cherry picked, and AMD RyZen wins about 60% of them, but we don't have any results with the most popular benchmarking apps.
Be sure to follow Paulshardware, JayzTwoCents, TweakTown, BitWit, LinusTechTips and others for some real test results on the 28th of february, 2017. These guys have a lot of video cards and Intel CPUs for many different tests. It will be interesting to see how RyZen will handle video editing, live streaming, gaming and synthetic benchmarks with low and high end video cards, from both manufacturers (AMD and nVidia).
I'm guessing AMD will start making massive discounts on the AMD FX processor line and AM3+ motherboards, as they will be completely replaced by the RyZen generation and 28nm Bristol Ridge CPU/APU chips. The cheapest (Quad Core) RyZen CPU will be around 130 USD, so these older technology 28nm processors will fill that void and also replace the FM2+ chips. So be sure to check out these categories at amazon.com, as they still offer impressive performance for the price, and some users may be satisfied with their capabilities for at least another 3 years.
