When it comes to dual-core 35W Core i7 and Core i5 Haswell parts they won’t come at least until Q4 2013, at least this is the current part. Core i7 3540 launched in this quarter, Q1 2013, and it is a 3GHz dual-core with four threads and a top turbo frequency set at 3.7 GHz. It is a 35W, 22nm Ivy Bridge part with 4MB of cache memory. A replacement part might be on the way with a slightly higher clock in Q3 2013, but the Haswell based replacement is set for Q4 2013. With an official price of $348 it is not really the cheapest kid on the block.
Core i5 3380 remains the fastest dual-core 35W Pentium part until Q4 2013 Haswell reinforcement. The 2.7GHz / 3.4GHz turbo clocked dual-core will remain the fastest in this league at least until Q3 2013, when it might get slightly faster version of the Ivy Bridge based core, but it won’t be replaced by Haswell 35W dual-cores before Q4 2013.
Intel definitely wants to prioritize the quad-core 55W i7-3940XM $1096.00 replacement called Core i7 4930MX and Core i7-3840QM replacement in $568 market segment, branded as Core i7 4800 MQ, as it can simply make more money on these pricey these parts. These quad-core Haswell parts start selling in Q2 2013, followed by 17W Ultra low voltage dual-cores in Q3 2013 and only after these two lines rolls out, Intel will introduce the rest of the Haswell line-up.
