Man a 57w TDP.. Surprised its not lower but it sure is powerful..

would love to know what those numbers mean in better detail.

Why is there an X in the cpu name? Are people really going to OC a laptop?

@Wanderer11 Yes, yes people paying $1k for a CPU - which is what this will cost - are going to OC a laptop. the Alienware M18x with the 2920xm could sustain 4.5 GHz with the stock paste and air cooling due to its awesomely open and configurable BIOS.

performance seems pretty good for a mobile CPU.
PS many asus gaming laptops allow you to overclock the CPU (though generally through overclocking presets.
If something can be overclocked safely then it should be as it is free performance.

Not sure about the X but yeah people overclock laptop CPUs in their laptops. Some laptops have decent stock cooling systems and so they like to push the limits.
For instance my tactic is generally to buy a laptop with great cooling, great looks, and decent GPU and underlying hardware and interfaces. Then down the road when the highest end CPU is like $150 I buy it and swap it in! For instance with my G50VT, started with a P8700 then went to an X9100 for $110 and keep that guy at about 3.3GHZ and 90C when I'm crunching (nearly 24/7). Tough CPU

3GHZ stock clocks on a mobile quad core is awesome! First time they've hit that clockrate with the Nehalem/post Nehalem architecture.
I remember when it topped out at 2.133GHZ with the 1st gen quad core i7 (45nm), the dual cores at the time were 32nm.
14nm, who knows, bet they will reduce the power to 45w and bump it to 3.2GHZ base and then 10nm hopefully 6 cores.

Why no Iris graphics (HD 5200) in this CPU? Since it isn't a thermal problem, since the components can dynamically clock on demand, why not put it in.

respectable gaming without a discrete graphics card is the holy grail yet it never seems to pan out year after year. 1366x768 at mid or low res isn't respectable gaming. 1920x1080 at mid to high on a laptop with built in graphics would be.

If I'm not mistaken Haswell moved the voltage reg on die so that adds some TDP and having 2010 (or so claimed) GPU performance on die probably bumps that but a big chunk too.

What I'm wondering is if that eDRAM would also help CPU performance, and by how much and in what type of task. Supposedly both can use it.

the gpu will more or less be phased out at some point, graphics in games cant infinitely get better unless there is some way to automate it, so there is an upper limit to what we can do graphicly, and while you could make a gpu more powerful than integrated, it will be a specialty item like sounds cards are today, you get them for a reason, you have the high end need.

"In addition to evidently allowing games such as Battlefield 3, Need for Speed: Most Wanted (2012) to be playable at 1366 x 768..."
So in other words, the on-die GPU is still no better than what an old mid-range dedicated GPU can do for playable frame rates in those games today. Still far from impressive.
What would be great is if Intel or AMD (or both) could figure out how to make a bus architecture where the iGP from their CPUs work with the dedicated GPU to boost performance. Otherwise, that iGP is a waste of money and resources for the power user (gamers, graphics & video users) who drop the coin on performance video cards.

I own an m18x R1 and am very familiar with this laptop inside and out. I upgraded the heatsink to the triple pipe r2 version and i upgraded the gpu to gtx 680m in SLI. I run my i7-2960xm at 4.2Ghz yes 4.5 is attainable but i like keeping my voltage lower. The cpu performance of ivy bridge was actually equal to sandy bridge because ivy oc'd a few hundred mhz lower so the ipc improvements were negated by the slower clock. So I didn't feel bad not having the i7-3920xm. Obviously Haswells i7-4930xm performance at maximum OC should beat Sandy's i7-2960xm performance at maximum OC but will it beat it by a significant enough margin, i doubt it. Looks like I'll be keeping the R1 for another generation.
