This is big news: Dell has confirmed they are the OEM exclusive partner for AMD's upcoming 12C/24T and 16C/32T parts in their upcoming Ryzen ThreadRipper CPU range.
Dell will be pumping out systems with Alienware and their upcoming Area-51 ThreadRipper Edition gaming PC that will rock up to 64GB of DDR4 RAM (2667/2933MHz), a bunch of GPU configurations including the GeForce GTX 1050 Ti, Radeon RX 570/580, and GTX 1080 Ti cards in SLI. I'm sure there'll also be some Radeon RX Vega graphics card configurations once the Vega-based GPUs launch in August.
All systems will include fully unlocked, factory overclocked on all CPU cores and liquid cooled Ryzen ThreadRipper CPUs, with options for dual- and triple-GPU configurations and super-fast M.2 storage. Dell will also be selling Alienware Area-51 gaming PCs with Intel's new Core i7 and Core i9 processors, but Intel is locked out at anything more than 10C/20T. Intel will be offering their Core i7-7800X (6C/12T @ 4GHz), Core i7-7820X (8C/16T @ 4.5GHz), and Core i9-7900X (10C/20T @ 4.5GHz).
