Intel To Expand Core M Broadwell Line With Faster Dual-Core Processors
MojoKid writes: Intel didn't waste much time following-up on its initial Core M lineup launch. The company has added 4 more Core M models to its roster. Like the launch chips, these four are dual-core designs that support HyperThreading to enable an effective four logical threads for processing. Also like those earlier chips, these are spec'd with a TDP of 4.5W. These new chips, however, are generally faster than the launch models, with a new top-end processor called the M-5Y71. This chip has a base clock speed of 1.2GHz, but is burstable through Turbo up to 2.9GHz. What really sets these chips apart from the initial Core M models is that their TDP is scalable, based on what the builder is looking to do with it. If the chip is set to be used in a notebook with very little free space, the OEM could opt to drop the chip down to 3.5W and lose 600MHz in the process. By contrast, a bulkier notebook could handle a hotter chip better, so a higher TDP could be decided upon. If that route's taken, any one of these new chips could peak at 6W and add 200MHz to the base and top-end clocks.
Very cool technically speaking, and good for system designers ... it will, however, make it that much harder to comparison shop, if the same CPU has a different speed depending on how it's wired up.
Well, if the peak (judging from the last sentence of the summary) is 6w, that is easily in the power envelope of USB. (6w = 5v@1.1a) so, all they mean is a larger Passive cooler. You probably don't need a Heat-sink-fan unit until about 10-15w

There might not be much room for overclocking, since we know Intel has been having lots of trouble with their 14nm yields.
It's possible that they're rolling out low power dual core chips because that's all they can produce in any significant volume.

o0t!
If it's like their first M processor, the turbo boost mode only works when using a single core. i.e. You can run one core at 2.9 GHz, or you can run both cores at 1.2 GHz. That's the price you pay for the extremely low TDP. In contrast, an i5-4250U has a base clock of 1.3 GHz, can turbo boost to 2.3 GHz on two cores, and 2.6 GHz on a single core.
You make a funny but frankly there realy is no reason for AMD to follow Intel down the rabbit hole of ever lower nm sizes (which if rumors are true is ending up with worse yields and lower clocks do to leakage with each rev) because what Intel doesn't want to admit that AMD seems to have accepted is that CPUs have gone waaay past "good enough" and into insanely overpowered for all but the handful that are doing jobs that stress a CPU to its limit and those folks would be better off with a dual socket workstation anyway.
What jobs do Joe and Jane Average have that won't be well served by a C2Q or Phenom X4 from 7 years ago? None, not a damned thing, in fact many can get by just fine on a C2D or Athlon X2 and never notice any difference because they just aren't stressing the chips. Hell its even true of the gamers who traditionally were the first adopters, with the first gen i5s and Phenom II X4s and X6s able to play pretty much any game out there when paired with a $150 GPU. When the MHz war was in full swing I was getting rid of my PC for a new one every other year with a major upgrade at the halfway point, but now why bother? I got 8GB of RAM, a 6 core CPU, a board that will take up to 4 GPUs in crossfire and 3TB of storage for my games so why waste money when it'll already play everything and do everything I want?
This is why I'm not worried about what Intel does even though I'm an AMD exclusive shop, because a dual or quad APU laptop or an APU or CPU based desktop does everything my customers want it to do and will last them for many years. this is why I've branched into home networking and HTPC setups as the days of the 3 year upgrade cycle are well and truly over. Intel can fill their bins with bad chips chasing 0nm all they want, the simple fact of the matter is computers have become like washers and dryers, no need to replace 'em until the previous one dies. I predict ARM will be in the same boat in 2 years or less as like X86 they are ramming into the thermal/power wall and soon won't have anywhere else to go, hence why we are seeing 8 core phones and tablets and the local Walmart is selling dual core tablets for $48. ARM devices are already becoming overpowered compared to the jobs ordinary folks have so all they can do is throw more cores or lower the prices. But that will only take you so far before you are in the same boat as X86, more cores than most need and prices so cheap everybody has more than they can use.
