The new Broadwell Desktop CPUs are based on the LGA1150 pin layout and will be compatible with the current Z97 motherboards.
ASUS and ASRock recently announced that their motherboards will be able to handle the new 14nm Broadwell processors with a BIOS update. The two new CPUs will be the Intel Core i7-5775C and Core i5-5675C.
There are some odd things on this list. It is not clear what the C stands for in the product names. Our local AMD fanboy says it stands for C*ap while others have suggested, camel or caramel, depending on how hungry they are. The processors are unlocked for overclocking like the previous K models were and it could the K has somehow become a C.
The new i7 has four cores and eight threads running at a base frequency of 3.3GHz and with a turbo to 3.7GHz while the i5 has a base speed of 3.1GHz and a Turbo of 3.6GHz on its four cores, four threads base. The i7 comes with 6MB cache while the i5 only has 4MB and both are powered by the Intel Iris Pro Graphics 6200 iGPU.
