Waiting for Haswell MBP Mega Thread

Battery life is not given by iGPU, but Haswell's low-power states. The power draw from the HD5200 is the same and some situations even bigger than from combination of i7 with HD4600 + GT750M.

I dont know how many times i will have to say that again. iGPU will NOT increase battery life. Power draw is THE SAME. Only low power states make difference here, and its not from iGPU but from CPU.

Print, poster it over the bed, remember. Everyone.

I'm hoping for:
13" 1.3GHz i5, 256GB SSD, 8GB RAM
13" 1.3GHz i5, 512GB SSD, 8GB RAM
13" 1.7GHz i7, 512GB SSD, 16GB RAM
15" 1.3GHz i5, 256GB SSD, 8GB RAM
15" 1.7GHz i7, 512GB SSD, 16GB RAM
15" 1.7GHz i7, 512GB SSD, 32GB RAM

These clock speeds are not plausible for the MBP.

Why do you think there would be new Spring 2014 rMBPs?

Nothing concrete actually, besides Murphey's Law which always seems to bring about some kind of hardware refresh a few months after I get a new Apple toy for Christmas.. :D

My first Mac was a prototype Skinny Mac (i.e. 128KB of RAM) in August 1983. It wasn't mine, but it was on my desk. I wish it were mine and I still had it. :)

So cool. :) My dad let me play with his Commodore VIC-20 when I was a kid. I wish I still had that. :)

I strongly disagree. I'm quite happy to have five steps forward and one step back. Please feel free to buy an Ivy Bridge rMBP if the iGPU is so important to you.

I'm in that same boat of a massive net performance gain in my next hardware purchase. Even then, some folks should also fairly consider the possibility of "regression" as market development too. For instance some car manufacturers may introduced a "new" model with a lower maximum horsepower while providing a more desirable response throughout the powerband. Just a quick and dirty example, but the point being that not all "regression" occurs in a vacuum.

Are there any confirmations that they, Apple, will discontinue the cMBP?

No, just speculation, but it's based on a seemingly clear trend. The internal optical brick is dead.

The routine (since the switch to Intel CPUs) seems to be one revision per year, sometimes dramatic and sometimes minor, following availability of each generation of new CPUs. This year was an exception, with a very minor additional revision in the winter. Because Apple's costs for the Retina displays had come down so much and they were not selling well at the high prices required by Apple's initial Retina display costs, Apple cut prices and at the same time bumped up processor speeds by 0.1 GHz. I don't think there were any other changes between the late-2012 and early-2013 rMBPs.
 
if not september 10 then when?

Also anyone know if the prices for current gen refurbs have historically went down as new models are announced? It sounds logical, but I have my eye on getting 13" rmbp with 512GB

Wouldn't it follow that the GPU side would be able to take advantage of the low-power states as well?

Seriously? Those are MacBook Air-style processors. Any and every processor in the MBP will have a higher clock speed.
 
mcarling said:
A 32GB RAM option is unlikely before DDR4. 512GB RAM is obviously a typo and should read 512GB SSD. I'm not sure Apple will retain the 128GB SSD option for the MBP, although they did for the MBA.
Click to expand...

I know why Apple offers a 128GB SSD, but I don't see the point of that. Anyone buying a rMBP should go with at least 256, even if you're a light user.

Can we really expect to see 256GB as standard? I'm sure not expecting it, but that would be awesome.

The rMBP doesn't do that.

Under Mavericks, only 2 applications I have actually invoke the dGPU:

Photoshop CS6
iOS Simulator

Everything else runs on HD 4000.

And I'm seeing close to 9 hours of battery run time on a daily basis.

Yep. I keep telling everyone this and no one listens....

An iGPU doesn't get power for free. Just like a dGPU, it still has to draw extra power. So the overall requirements for an i7 + Iris Pro are higher than just an i7.

So the best way to reduce power usage: Include a normal i7 with a non-Iris Pro iGPU, and then a dGPU. Turn the dGPU off when it's not in use. That way the overall normal power usage is lower than an i7 with Iris Pro.

It is just hard to believe that Iris Pro will draw more power than an i7 + dedicated GPU. Is there a review/facts that state this is true?

No, because it's not true. It's wishful thinking, seemingly from folks who have a quasi-religious preference for discrete components over integrated components. Just add up the TDP for each. The TDP for a discrete GPU is much greater than the difference in TDP for two otherwise comparable i7 Haswell CPUs differing only in Iris Pro HD graphics versus 4600 HD graphics.
 
Any chance this is going to be released in the next two weeks? My work place ordered a base 15" rMBP w/ 16GB RAM and it is not going to be here until Sept 5.

That's not even close to Sept 10! :eek:

Methinks tis wishful thinking.
 
Hopeful yes. The last time we ordered one with a shipping time slip, it was the last speed bump. So my hopes are not unfounded. ;)

So you ordered a model and got the new release because of a shipping delay? Cool. :D

I haven't dug into TDP data, but aren't some people rationalizing a CPU+Iris Pro + dGPU by saying that Apple could manage the power threshold of the chips? Even *more* conservatively than the current setup? o.o
 
Are people suggesting that Iris Pro would draw more power than a dGPU? I thought the whole thing was that a dGPU used more power/battery life than any kind of integrated GPU. No, an iGPU isn't power free, but it has to be way better for the battery than a dGPU offering.

That's not because of the iGPU, but because of the lack of a dGPU.
