A couple of days ago there was a rumor about an upcoming Ryzen HEDT platform from AMD, which would be a competitor for Intel's flagship processors. According to the rumor, this new platform will require a new motherboard because it uses a different socket and needs the AMD "X399" chipset. The platform reportedly offers more cores, quad-channel DDR4 support and more PCIe lanes than the current Ryzen lineup. The previous rumors indicated this is basically a multi-chip package with two Ryzen 7 dies.
Now French tech magazine Canard PC Hardware reports second-generation B1 engineering samples of the Ryzen HEDT CPU are circulating among AMD partners. The tweet below talks about a 16-core, 32-threaded part that features a 3.1GHz base clock and 3.6GHz Turbo. The TDP is 180W and effective maximum power consumption may even be higher. The site stresses this is not yet the qualification sample, so this isn't the final stepping.
2nd Gen B1 ES for Ryzen 16C/32T on X399 platform incoming. Speed (and TDP) bumped to 3.1/3.6 GHz @ 180W on these samples. Still not QS.
