*HP ENVY 14 & ENVY 14 Beats (2XXX series) Owners Lounge*

I don't know about that. Usually if you upgrade everything but the battery, you're going to have shorter battery life because upgraded parts usually draw more power. But we'll find out once it's released.

It still doesn't change the fact that if he's concerned about battery life, he can get the slice battery attachment and that should give him plenty.

 

It will have better battery life because Sandy Bridge is more power efficient than Arrandale.

 

Let me give you a very simplified example.
Chip A uses 5W of power and operates at 10mhz.
Chip B uses 7MW of power and operates at 15mhz.
Chip C uses 10 MW of power and operates at 18mhz.

Chip B is most efficient, Chip A uses the least power, and Chip C operates the quickest. The best on battery life is Chip A, but Chip B is the best value, and Chip C will give the best performance. Battery life isn't tied to power efficiency. Only if they're operating at the same performance does it really make sense to bring efficiency into the picture.

As far as battery life on the Envy 14, it remains to be seen specifically which processor it will use. There's a wide range of SB based processors.

 

In short, I agree with abaddon. Sandy Bridge gives more battery life than Arrandale.

Quad core SB CPU's obviously have battery battery life because an i7 2630qm has switchable graphics while the 1st gen i7 720qm doesn't have it.

 

probably they are going to use the duals and quads

and since as said the power gating and the c-states are better, its going to give more battery life

 

They will have better battery life, nothing mind blowing though.

 

She is from the UK and they are not available here, seen one on ebay for £250/roughly $410 once upon a time...

 

Every notebook that has had Arrandale and has been refreshed with SB is getting better to significantly better battery life than the previous generation with no other changes.

If it gets dual-core SB then it will have better battery life and if it gets quad-core, it will be close. I don't even know why you are trying to argue this. SB is more efficient and more powerful than Arrandale despite the fact that it has a lower clock speed.

 

... wait.. the sandy bridge i7 has switchable graphics? That is great news! That should mean that the 2nd gen i7 will be less of a power drain than the 1st gen? Ouh, that will make the choice between i7 and i5 more difficult...

And I hope I'm not alone when I say I'm SO TIRED OF WAITING. If the US release date is only 10 days away, then its starting to get ridiculous that no official datasheet is available yet. Even though the European release date might be a little later than the US date, I want to know that it will be worth the wait

 

I'm not arguing about the efficiency of the chips. You completely missed the point if you think that's what I'm saying. I'm saying the efficiency isn't necessarily tied to how much power will be used.

 

A more efficient processor is able to complete the same task with less power.

 

Yes, I'm well aware of that. But we're not talking about the efficiency of the processor. We're talking about the total power draw that the processor has. It could be extremely efficient, but if it has a large power draw then the battery life will be less. If it has lower draw (even if it's less efficient), then the battery life will be longer.

 

The power draw will be lower
both are 45W cpu's (but considering the insane high idle 15W for 1st gen quadcores, and the low 3W idle for sandy bridge quadcore, it will be drawing less power)
And than I didn't talked about the switchable graphics that are now available in the quadcores...

 

The power draw is not going to be maxed out constantly at 45W.

Wow thats a great improvement.

 

Efficiency is directly tied to how much power is used. A more efficient and faster processor will be able to complete a task faster while using less power to do it. That will also allow the processor to go back to lower states/idle faster, thus adding to the difference in battery life. I don't know why you are mentioning power draws as SB has the same TDP as Arrandale and full load but much lower under light-medium loads/

 

You guys just don't get it. Pay very careful attention to what I'm saying, instead of guessing at what I'm saying. We don't know exactly which processors are going to be used in the next Envy 14. We don't know exactly which GPU, and we don't know how much the other parts are going to draw. We can't really make any sort of claim about the battery life.

And for your power efficiency idea, I again direct you back to this post:

 

The GPU they use won't matter, as long as it has switchable graphics. There is no reason to assume it won't because almost every notebook nowadays does.

There is no reason the other parts of the draw more power than in the current-gen Envy and, since we know the processor will draw less, it is a given that the next-gen will have better battery life, even if it isn't much.

 

could read what c-states and power gating means? this could have avoided this discussion.

also read about turbo boost, which is directly related to the power gating

and yes the envy SB will have more battery

 

Only 10 more days...

 

I'm well aware of what those are, and I still stand by my argument. There's no point in speculating about the battery life because we don't know exactly what changes have been made. We'll know soon enough once it releases.

 

We know what CPU will be inside (35W dualcore parts, and 2630QM en 2820QM 45W quadcore components)
GPU will be 6630M (same TDP as 5650M)

The difference will not be made in memory or harddisk power...
If your statement was true (but it isn't). How can the new alienware mx18 be faster AND have longer batterylife (?)

 

Everybody needs to take a chill pill. We have 28 pages already and, out of them all, we've only learned two things about the new Envy 14:

a) it has a Sandy Bridge processor
b) it's going to be released on June 15

Quit speculating!

 

Again, you didn't pay attention. I'm getting bored of repeating myself for people who can't read. Go look above where I posted the example about the processors and their efficiencies.

 

c) improved trackpad
d) HP CoolSense 2.0
e) backlit keyboard (again)

 

More like 6 pages. Get on that 50 posts/page, bro.

Sorry, auxillo, but what you are saying makes very little sense. It might make sense if SB drew more power than Arrandale did or ran at higher clock speeds, but it doesn't. The three biggest power draws on a laptop are the screen, processor and graphics. We know what processors the next-gen will have and we know they will consume less power than last-gen most of the time. We know what graphics the next-gen will have and we know they will consume less power than last-gen most of the time. I guess you could argue that they might put a super bright screen in but, barring that, the next-gen will have better battery life.

 

...but knowing that the new i7's have switchable graphics which might make it less of a power drain than 1st gen... which one would you choose this time around; i5 or i7, assuming they cost just about the same?

 

Assuming they cost the same I would go with the quad. So far we have seen that SB quads get pretty much the same battery life as duals.

 

That would depend on what your goal is: performance, or battery life?

 

What about heat issues with the SB i7? I know most ppl shied away from the arrandale i7 because of heat and battery life and went with the i5.

So basically what I want to know is if it is safe to get a SB i7 or not?

 

Hi All,

I'm a lurker but after reading the posts by "Auxilio_ab_alto" I just thought I would point out to anyone who is confused, that it is pretty much confirmed that the Sandy Bridge updated Envy *WILL* have better battery life. How much better? Can't really say yet.

We know for sure that it will have better battery life because the Sandy Bridge architecture does in fact reduce *overall* consumption compared to the current generation, while also increasing speed. So thus, it is more efficient AND uses less power than the current generation.

We also know that the updated graphics will NOT increase battery consumption in any way as long as you are using the integrated (Sandy Bridge) graphics while you are running on battery.

Auxilio_ab_alto, I wish you would stop repeating and realize that we can look at all of the other laptops that updated to Sandy Bridge from the existing architecture and we can see that in every instance, battery life has improved, which logically makes perfect sense. I hope you're not offended, we all make mistakes.

 

If they get just about the same battery life, the choice will get so much easier... its funny, because in my country, the current-gen Envy 14 with i5 (the 4gb/320gb, only one left on the market here) costs like 180 USD more than any i7 model (even the Envy 14-1260 with 8gb/750gb is cheaper..) I guess the second worry with the i7 is the heat?

In an ideal world I'd say the highest possible performance with the longest possible battery life.. just like Winnie the Pooh, I want both But let's just say that I'll pick the i7 if the battery drain and atleast some of the heat complaints have been solved, and the i5 if there is a major difference in battery life and the i7 gets crazy hot..

 

I second this..

 

If people would stop making ignoring what I'm saying and yet question what I'm saying, then I would stop repeating the same points.

You're implying I've made some kind of mistake. Not really possible, when the only stand I've taken is that we don't know for sure what the battery life will be, and that the processor isn't the only thing that determines battery life. Two easily defensible and sensible positions.

What I plan on doing is the i7 with the slice battery. Although probably the most expensive option, it's probably the best of both worlds. I'm not sure about heat issues with i7. For that, you'll probably need to wait until reviews come out.

 

You still either don't understand or don't want to

We know which processors will be offered and that they will consume less power than these current ones.
We know that includes an integrated GPU that uses the same power.
We know the screen is the same, same power.
Hard drive consumption will be the same.

What else do you need addressed?
There might be a different touch pad! So that could consume more power! But the power consumption of a touchpad is so negligibly small that it won't make a real world difference. The battery size is certainly not going to shrink.

Again, we know that the battery life will be better. We don't know how much better but even that can be *estimated*.

 

Ugh, getting very old.
Nice opening. Making two claims so that it appears that those are the only possibilities. Never seen that before...false dichotomy
We do not know specifically which processors will be offered in the Envy 14. We know they'll come from the Sandy Bridge line yes.
We don't know that the screen is the same. We don't know if the discrete graphics used will draw more or less power. We don't know if hard drive consumption will be the same, even though that's a comparatively small aspect. There are other parts that could each have a small effect on it that we don't know about. There's enough variables in this that we can't say with any certainty whether it will have better or worse battery life.

 

We do know that the choices of i3 i5 and i7 Sandy Bridge processors offered will use less power. Look at the spec sheets. Look at the other machines that have taken this same upgrade to SB. We do know that the screen is the same - there is no screen they could upgrade to that would increase power consumption in any notable way. The system will have a 7200 RPM mobile hard drive (5400 may also still be available). We know what they consume. It wont change.

This whole time you have been saying:
"Yes, I'm well aware of that. But we're not talking about the efficiency of the processor. We're talking about the total power draw that the processor has. It could be extremely efficient, but if it has a large power draw then the battery life will be less. If it has lower draw (even if it's less efficient), then the battery life will be longer."

We are telling you, based on facts, that the new processors total power draw will be less than the current one. Case closed. You were wrong. The quotes and facts are right here in black and white to be read.

I will not address you again because clearly at this point you are just trolling the forum. I only came here to set the record straight for those who may be misled. Power consumption will be less and I respectfully am letting you know that you are incorrect. I guess this will be clear in 10 days way, so it's not even worth going on and on about any further. Have a good day.

 

Oh, I'd totally do that too, had the slice battery still been available here.. it sure would have been close to the ideal

 

Apparently I'm a troll for standing by what I said, which was based solely around the argument at hand. I think you need to look up what a troll is if you think I'm trollin.

 

I do not see why you have been arguing for 3 pages now about power efficiency, just shut the up already.

Any new i5 is more power efficient than the old aswell as way more performance. All the i7's except maybe the, 2820 and up not sure on there tdp compared to the old one, are more power efficient. Simple as 1-2-3.

Now can you quit your ing about battery life and get some productive discussion going again like where is the spec sheet for there product that is to release in 9 days !

 

That's really a subpoint to the whole argument. The processor is but one part inside the computer.

I don't see the point in discussing "why is there no spec sheet" for it. I can't imagine that resulting in anything "productive" as you seem to think it will. It has no spec sheet out yet, and we can't change that, and no amount of arguing will change it. Just like no amount of posting about the battery life of it is going to change it. We will know everything we need to know in a few days, and it's pointless to stress this much over it. It's especially pointless to get worked up to the point where you lose your temper.

Simple fact is, I keep responding because people keep misrepresenting what I'm saying in an effort to make their viewpoint credible. If you were to stop posting about it, the argument would probably go away.

 

you really know how to ruin a thread. I am so sick and tired of you arguing on every thread. I keep getting on here thinking new info is posted but of course not. It's the new guy that thinks he knows everything and has to repeat his view a hundred times. you really make me feel like I'm wasting the short amount of time I have to look at this forum.

 

Feel free to find all of the two threads where I've gotten into an argument that's lasted more than 2-3 posts. Here's a link to get you started:
http://forum.notebookreview.com/search.php?do=finduser&u=424919

Truth is, you got into one argument with me, and now you're out looking for blood about me. Do you not have better things to do than to make this personal? I'm really much more interested in the Envy 14 than starting some kind of pointless feud.

 

9 more days!!!!!!!!!!

Keep this thread open!!!

F is for friends who do stuff together!
U is for you and me!!!
N is for anyone and anytime at all!

Down here in the deep blue sea!!!

 

Straight logic.

I fail to see how your your example proves your point. The only way your theory makes sense is if you are constantly maxing out all the processors, and even then the weaker one would have a weaker workload and that is the only reason it would get better battery life.

Processors don't constantly run at peak power consumption.

Giving the same task to all the processors, the more efficient one will do it and use less power. That is what efficiency means.


I get what your saying about not knowing the exact components, but common we all pretty much know it will have some sort of battery life improvement.

 

I second that

 

Lol yea everyone just drop it.

Any news on specs or spec sheet release date?

 

I've been Googling HP Envy 14 multiple times per day for about three weeks now, and haven't had any hits recently. But I would assume soon since it's 9 days away now.

 

Ya I keep checking the Google News also to see recent articles.

 

Haha, I'm so glad I'm not the only one! Is anyone planning on getting day 1 regardless of the newer specs? I'll be interested on hearing the first review!

 

Ya I am, I was set on the old one just waited for this one incase of a better GPU. Just hope my LLC filing is completed by then so I can write it off as a business expense.
