These are all mobile processors and the nine new Haswell additions are split between Intel’s Core i5 and Core i7 families. The four new Core i5 processors are the 4310M, the 4310U, the 4340M, and the 4360U. All four boast two hyper-threaded cores and pack 3 MB of L3 cache. The Core i5-4310M features Intel HD 4600 graphics and is clocked to 2.7 GHz while the Core i5-4310U is clocked to 2 GHz and features Intel HD 4400 graphics. These are priced at $225 and $281, respectively. The Core i5-4340M boasts a frequency of 2.9 GHz and HD 4600 graphics and is priced at $266. Rounding out the new additions to Core i5 family is the Core I5-4360U. This chip sports a 1.5 GHz frequency, HD 5000 graphics and a price tag that reads $315.
The new Core i7s include the Core I7-4940MX Extreme Edition, which debuts at $1096. This quad-core CPU packs 8 MB of L3 cache, a clock speed of 3.1 GHz, and integrated HD 4600 graphics. Next up is the quad-core Core i7-4910MQ with 8 MB of L3 cache, clock speed of 2.9 GHz and HD 4600 graphics. It’s priced at $568. The Core i7-4810MQ is clocked at 2.8 GHz, packs HD 4600 graphics, and costs $378, while the Core i7-4860HQ is clocked to 2.4 GHz, boasts HD 5200 graphics and costs $434. Both include 6 MB of L3 cache. Lastly, there’s the Core i7-4610M, which packs 4 MB of L3 cache, two cores and a 3 GHz clock speed. It costs $346 and comes with HD 4600 graphics.
Rounding out the lot is a new uLV Celeron. This dual-core CPU is clocked to 1.1 GHz and packs 2 MB of L3 cache. It’s priced at $107.

IMO, there is way too much hair-splitting and inconsistencies (with desktop models) in Intel's mobile lineup.
Same goes for moblie gpu market where under desktop name X you get X minus two performance tiers.
You really cannot rely on model number or product line with Intel's "simpler" numbering scheme. The simplest way to compare models these days is to use tables.
I find it ironic how Intel used to say the alphabet soup after the CPU architecture designation and clock speed as model numbers was "confusing" - seeing what they did to make things "simpler," the alphabet soup from the 386-P4 days seems like the simplest model numbering scheme Intel has ever had: pick a CPU family, pick a clock frequency, find the letters that correspond to the features you want, that's your model number now all you need to do is find the closest match.
As for the switch from the supposedly complicated (yet in retrospect quite simple) old naming scheme to the new "simple" (yet in reality convoluted and needlessly complicated) naming scheme, I would imagine that "simplicity" was just a guise, the reality of the situation was that using clock speed as part of the naming scheme became exceedingly less attractive when they ran into the 4 GHz thermal brick wall.
