As you are implying...of course not. I don't know why so many users grab onto things people state as a matter of fact in these thread and believe them to be true.

I can insist that I had a seance with Steve Jobs last night after playing with my ouija board, and he gave me the entire product lineup for the next two years, and then I called Tim Cook on his cell phone to confirm. It doesn't make it true.

Odds are good that any nuggets of information will come in the form of a brand-spanking-new article on the macrumors.com front page, and even then the source will probably be of questionable historical veracity.

http://www.ibtimes.com/apples-new-r...ed-october-launch-high-end-haswell-processors

It claims an October launch with an Iris Pro cpu and no price changes.

I find it highly unlikely that they are having supply chain issues with a part that's been used for well over a year now. This smells a lot like yet another nonsense so-called "news" article designed to get hits but offering absolutely nothing in the way of substance.
 
For this update supposedly not happening until October, all the stores sure are unloading the current models quickly. Also noticed that there are no 15" retinas left on the refurb store.

Its 100% what i told you about the price dGPU 8 gb ram(it was obvious already)

Lol. Who are you? Kuo's brother? :D

I prefer to wait... :D

I'm running Mavericks DP4 with 16GB on my 15" rMBP, and I constantly see 9-10GB RAM use WITHOUT activating any VM (running VM brings that to 12-13GB).

So why is it that people don't need 16GB RAM again?

Granted, not everyone will see that much use, but Mavericks is not a magical fix for those who do need that amount of RAM.

Memory compression doesn't work all the time. And just to say... disregarding cached memory (for closed applications), with just Safari, Mail, iTunes, and Finder open, it's already 5.6GB.

I hope apple will provide the option to disable manually the crappy memory compression...

Will there be a quad core option for the 13" is what I care about. Any insights?

The last leak showed a 2.4GHz dual core with Iris 5100, and looking at Intel's lineup, there's no reason to doubt that as the base processor. The 37W quad cores all have HD4600 graphics, which wouldn't fit well between HD5000 in the Air and Iris Pro 5200 in the 15".
 
Hello, first post and all that.

So in the case, are we thinking prices are going to stay the same? Or will there still be a £999 MBP? Surely this happening would be very hard to achieve?

And therefore, rather than waiting and being unsure which one to get I should bite the bullet and get the 13" Air if my budget is £1000?

You lose CPU cycles for compressing data in memory and the compression ratio is low...

What would happen if PS is idle while a 2GB TIFF image is loaded into memory and others processes need more memory? The OS would likely try to compress those 2GB in first place instead of swapping them onto disk, right? Compressing a TIFF would generally increase more than reduce the image. Worst, imagine the OS starts compressing and the user reactivates PS...

The end of story is compression wastes CPU cycles while not providing in most cases a substantial gain...

Apple will use memory compression hype as a marketing argument to justify the 8GB memory limitation in the 13" rMBP model. The 15" is not affected since it can have 16gb ram.

Kuo mentioned the same screen supply issues a few months ago. The only way that would make sense would be if they were switching screen tech.

Switching screen tech (to IGZO or similar) makes sense because it would let them use a less powerful backlight. Apple's recent announcements show that battery life is very important to them.

The rumors about the new thinner iPad 5 are stating the same thing, a new retina screen that requires half the backlight power.
 
I'm torn between the 15" rmbp maxed or going a slightly different route and getting the Samsung Ativ Q when it's out.

Now an Apple build quality OSX + iOS combo form factor at 13" with retina and good specs would make me actually explode with excitement.

The Samsung is a great idea but slightly crippled spec and Samsung build quality booo (for the record I like Windows 8 and use both OSX and W8 every day side by side on either my Air or mega Windows laptop with the other OS Virtualised. So I'm a neither fanboy) I think I prefer apple kit running windows than vice versa though. The Ativ Q is finally the first Wintel I've seen with no air vents underneath though so you can actually use it on your lap!

You are right, I don't sea how it will work for images and it's not like it will turn 8GB into virtual 16GB.

However- Apple claims up to 2:1 compression ratio, the same as IBM's POWER 7+ achieves, with specialized hardware.
So I wouldn't rush in downplaying the positive effect, especially considering that it works great for server systems.

2013 Macbook Air uses stacked memory, so there will be enough room for 16GB in new retina, and judging by the upgrade prices- why would Apple refuse your money? ;)
 
Crzyrio said:
Would this also allow for 32GB in the 15in? :p
Click to expand...

Air uses 2*4Gb, stacked on top of each other for 1GB per package, but there are also 16Gb (four stacked dies) for 2GB.
So technically- yes, especially if they free up some room by getting rid of dgpu and gddr5 memory, since stacked packages appeared to be slightly bigger.

AppleChampagne said:
Maybe with the new LPDDR3 from Samsung;)
Click to expand...

Modules used in 2013 Air are LPDDR3, but from Elpida, so it's not limited to Samsung, and as far as I'm aware, there are solutions for DDR3L also.
 
If Apple put everything in they possibly could (32GB RAM, 765M, etc) they would be a very different cmpany. Apple picks and chooses "revolutionary" updates. That is why we won't have a quad 13" this year, (probably) no 32GB option and no dGPU.
 
Here is another Iris Pro review, in German:
http://www.hardwareluxx.de/index.php/artikel/hardware/notebooks/27246-schenker-s413-im-test.html

The quality is not as good as e.g. an anandtech review, gaming performance is compared with only one other laptop (Asus with 650M, 2GB vRAM and quad core 3rd gen intel) and only on a few titles.

Iris Pro wins most benchmarks, while gaming performance seems to be a tie.

Some 3DMark - cloud gate numbers that are spread throughout the text:
4750HQ, Iris Pro: 9900
4900MQ, HD4600: 7000
4700MQ + Nvidia 740M: 8700

Keep in mind that this is the low end Iris Pro GPU, the 4950HQ should be a bit faster. Notebookcheck has the 750M at 10756 in the same benchmark.

Yep, I couldn't find anything on Elpida's web page, but here is a document from Intel:
LPDDR3 System Validation Results

Definitely, there are 16Gb packages out there (QDP- Quad Die Package), even though the document refer only to LPDDR3 for ULV Haswell's.
Click to expand...

16Gb in x32 LPDDR3 won't get to anything more than 8GB on Haswell chips - two x64 memory channels can only connect to four x32 LPDDR3 chips.

To get 32GB, sixteen 16Gb x4 DDR3L chips are needed, which exist as quad-die chips but they are very, very expensive.

I would say it is very unlikely there will be a 32GB MBP.

I work on memory interfaces for a fabless semiconductor company so I'm very familiar with stuff like this.
