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. 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). The models will get 4MB L3 cache but no hyper-threading for the Core i5 model. Check out the following overview I have compiled for you.
The new Broadwell SKus will be compatible with the Series 9 motherboards and Socket 1150 and are released in the retail channel on June 1st (NA, EMEA), and June 2nd (APAC). The i7-5775C and the i5-5675C are quad-core chips.
All the major motherboard manufacturers including ASUS and Gigabyte have already started rolling out Broadwell based BIOS updates.
Earlier this week we already have seen the flagship SKU overclock to 4.8 Ghz on air cooling. The Broadwell processors are listed on several e-retailers such as NCIX. And hey, pre-order prices .. ok ? Of course they will be lower once launched.
