Will Intel's upcoming processors once again break compatibility on existing motherboards? WCCF Tech came across some leaks that suggest that the upcoming 14nm Comet Lake-S 10-core processors will require a new LGA-1151 v3 socket and 400-series motherboard. The 10-core part will reportedly require more pins to draw enough juice from the socket.
It looks like Intel wants to make their sockets last two CPU generations and hence, the upcoming 10th Gen CPUs (Comet Lake-S) would also be supported by a new socket which is being dubbed as LGA 1151 V3. Now it is mentioned by Momomo_US that the new socket would feature more pins so it isn’t just a layout change but an entirely new socket if this is true. The socket would be used on the new 400 series motherboards which would include the Z490 motherboards series as the flagship mainstream chipset for K series processors.
Furthermore, the information indicates Intel is working on a 495 series chipset for the future 10nm Ice Lake-S processors. The site also writes word is going around that Intel is porting its Sunny Cove architecture to 14nm and that this may be used by the Rocket Lake-S processors. Take it with a grain of salt, but perhaps the 495 series will be needed for the Rocket Lake-S and Ice Lake-S:
Since Sunny Cove is the same core architecture which will be used on Ice Lake 10nm processors, it might be possible that Intel’s consumer desktop line of Rocket Lake-S processors can end up being supported by the 495 series chipset before a proper introduction of 10nm on desktop platforms.
