According to the folks over at Anandtech, Intel is planning to release an OEM only SKU in the high-end desktop lineup.
This new chip will be known as Core i9-9990XE which makes it the highest number part in the Skylake-X lineup. The current king would still be the the highest clocked processor in the form of i9-9980XE
The Core i9-9990XE will be a 14 core processor with a base clock of 4.0 GHz and
Other details leaked about the chip are that this will have TDP of 255W, which in Intel terms means the peak power usage will be higher. This also means the user would probably need a custom built LC solution.
Motherboard vendors will have to support 420 amps on the power delivery for the chip which effectively rules out the lower and most of the mid-end X299 boards.
According to the sources the chip will have no warranty and Intel will offer it to select OEMs via a series of auctions. Performance aside, the mode of selling and no warranty will make this a super duper exclusive keychain if the chip dies somehow.
All in all this sounds interesting, the chip can either be a very good clocker or an expensive keychain at the worst.
