Last year we first heard that Intel might be planning do stop using the LGA (Land Grid Array) socket in favor of a BGA (Ball Grid Array) socket. While we won't be seeing all-BGA CPU's with the Haswell release, it appears that Intel is shipping three CPUs in the Haswell lineup that will have a BGA socket.
For those of you that aren't aware of it yet, a BGA socket isn't exactly a socket. A BGA socket means that the CPU is soldered to the motherboard, and thus not removable or replaceable.
The CPUs that would have the BGA socket are the Core i7 4770R, Core i5 4670R, and the Core i5 4570R. As you can tell, the R-naming makes for the BGA socket, so keep an eye out for this when buying a new PC. Beyond the BGA socket, the -R CPUs will also carry an HD 5200 GPU rather than the HD 4600 GPU found on all other Haswell chips.
The current assumption is that the -R chips will make part of the NUC (Next Unit of Computing) platform, although this remains unconfirmed. We might also be seeing these chips in laptops and all-in-one systems.
