Haswell to have 10 hours of battery life in tablet, 13 hours docked in real world use

We also got an early glimpse of battery performance from Intel's incoming Haswell processor: you can expect to glean 10 hours of use in tablet mode, which is on par with many lower-powered tablets already on the market (think: Atom, ARM, et cetera). Factor in a keyboard battery (at least on this reference device) and you can expect an additional three hours of runtime. Unfortunately, there's still no word on when those next-generation low-power chipsets will arrive, although there's plenty of time till the next big PC show, Computex, rolls into Taipei.

So to summarize, Haswell will have battery life equal to ARM SOCs while being far, far more powerful. ARM chips are laughably pathetic in comparison to intel chips in terms of performance, yet the only metric that seems to matter is battery life for the most part (which is roughly 10 hours, on average for high end tablets).

IMO, broadwell is going to dominate the high end tablet market if this battery life comes to fruition in real world use; If intel prices their parts Broadwell competitively, there is absolutely going to be a shakeup in the high end tablet market. ARM SOCs just can't compete in terms of performance -- if prices are similar, intel is going to slaughter the high end tablet market. On top of this, intel chips have the ability to run any OS including android if they choose.

I guess "real world use" is mostly internet browsing and video playback. The same applies to ARM tablets - try to run something heavy (like GLBenchmark) and you will end up with 2-3 hours of battery life.
The biggest strength of Haswell SoC is going to be very low power consumption on idle and low load. Ivy consumes 5-7W on idle (including chipset).

I'm not disbelieving intel's marketing claims but for 10+ hours of active usage time we should wait for actual reviews.
 
IMO Arm is not going to last in the tablet market. The only thing their chips offer is low power. Once Intel gets theirs down to an acceptable power use why would anyone want Arm?

I would argue that this shakeup may happen long before Broadwell arrives. Haswell looks set to dominate the high end tablet market beginning in the second half of this year. Broadwell will surely extend that domination but I don't see ARM competing in the high end tablet/convertible market much longer.

I suppose adoption depends highly on the price Intel is willing to sell these chips for though.
 
Intel's prices on the Y model chips will have a large impact on their tablet marketshare. I'm not sure we can guess how much this will end up hurting ARM.

I'd imagine real world use to be defined as what is typically done on a tablet. Which isn't excessively demanding. Additionally, the article states that Haswell battery life is roughly comparable to the latest Atom SOC, which as I understand it is very very good - obviously the Haswell ULV will perform far better. Personally i'm really excited by this. I absolutely *love* the idea of the microsoft surface pro, but it has horrible battery life in comparison to traditional tablets. Haswell should fix that up quite nicely.

This is existing atom battery life compared to ARM SOCs:

Because ARM cost $20 and haswell costs $200

Actually, ARM SOCs have a wide range of options and a wide range of prices depending on that fact. I would imagine intel will position the ULV haswell for 500$+ high end tablets.

Now - assuming that 10 hours of battery life is true, just imagine how broadwell (Haswell's "tock") will do. It should be that much better than Haswell, which leads me to believe that intel will be an extremely strong player for tablets in 2014. If I had to stare into a crystal ball, I could see intel doing extremely well in the 500$+ tablet segment, while ARM SOCs will be relegated to the lower end. I'm just speculating, though.

If you won't, I will.

I can't remember the last time a company made a pre-release claim about battery life that actually panned out in real use.

I think it may be the real thing this time. Intel has stated many times that Haswell is the single largest generation to generation efficiency leap ever in their history. That would be an impressive feat.
 
While this is interesting I really don't need more power in my tablet. I have a Galaxy Tab 2 10.1 and for everything I do with it I don't notice the lack of computer. It plays video smoothly, does the internet fine, Skype, etc...

What I'm really interested in is what the TDP on the Haswell notebook quads will be. Right now Ivy does 35W for a quad. I'm hoping to see 25W for Haswell quads.

Android (and IOS) has been developed specifically to hide how slow the computers running it actually are.
 
Wait for real world reviews. Marketing spin, with no real information is pretty much useless. What size battery? Doing what tasks? Screen size and pixel density? What GPU?

I'm looking forward to Haswell, as it's time for a new desktop. But Haswell in a tablet? Too many unknowns right now.

i dont think intel has really ever inflated anything they claim.

So if they say 10 hours... im willing to bet its actually 10hours.
But its not gaming or crunching which they define active.. its probably watching a movie or doing office productivity software of some sort.

arm will still win

Will win at what? Super low cost chips? ARM SOCs will be like AMD if intel beats them on battery life while having 20 times more performance.

If haswell matches ARM SOCs in battery life, that means broadwell will slaughter them. All while being much more versatile and having better performance. ARM SOCs can't run windows x86, like someone else mentioned - android and iOS were designed to hide their poor performance. Efficiency is their only good trait. If intel beats them by that metric, they will dominate the high end tablet market.

-this seems to be the best reply
-being a mobile noob
-tablets to replace PC [ re the many pc is dead threads] and laptops in a business arena , tablets might need more than a web surfing\picture sharing lol mickymouse software.
Cindy in a board meeting -asked by the CEO do you have the sales figures broken down by the day in the last 3 years in excel , yes sir it's down loading now it's only 400 pages, should have it after lunch,
-CEO ok it's 10 am lets stop the meeting until Cindy gets the Data come back at 01.00 pm.
 
When you see how quickly the iPad Mini overtook the big iPad, it's easy to see that the form factor is important, as well as the price. These Haswell tablets are going to be uncompetitive on both fronts.

Once again, too much on performance angle, and too little on the "good enough" factor. Besides ARM isn't remotely close to AMD one bit, the biggest device makers are designing their own chips, and Samsung is fabbing their own on top of that. Why would they switch when most consumers don't even care what inside their phones/tablets? So they can become bitches to Intel like PC OEMs now?
