Intel Broadwell processors. For the PC side, the 14nm desktop Broadwell processors will be the Core i7-5775C & Core i5-5675C. These will be the first two Desktop PC processors, and as its now know they will launch mid-May.

Over at HKEPC, Lam Chi-Kui noticed a marketing slide denoting the date. Though there are no other details mentioned this does confirm two  LGA 1150 based SKUs to be launched prior to Computex.

The versions with the 'C" extension are the desktop LGA 1150 models, the 'R" models get a BGA socket. The C models will come with an unlocked multiplier (in the past that was K or X model). Initially five models will be launched but three of them are BGA and thus soldered onto the PCB socket. All Broadwell based ICs will get four cores, IGP wise the Iris Pro 6200 and JEDEC DDR3 1600 MHz support. And again all models will get a 65W TDP, which is lower compared to Haswell with its 84W/95W TDP. 

The models will get 4MB L3 cache but no hyper-threading for the Core i5 model.
