Waiting for Haswell MBP Mega Thread

My answer is entirely too obvious, so I must be wrong. But here goes... The 256 can hold twice as much data, it's twice the size, but there is no speed difference. Although things tend to slow down the closer you come to filling them up, therefore depending on how much data you store on your SSD you will likely be better off speed wise with the 256. But as far as I know, if you have 50 gigs of storage on either SSD they will run the same.
On a related note, does anyone know the difference in speed between the most recent retinas and the Airs that just launched?
I'm just a layman here, so someone like Mr M should answer this, but I would say there is no comparison between the two. The Airs are Core i5s and the 15" retinas are Quad Core i7s. In addition the Air maxes out with 4 gigs of ram and the 15" retina maxes out at 16 gigs of ram. Different beasts entirely. Somebody who knows more than me could elaborate.
Actually, 256GB tend to have more nand chips which means their writes speeds are faster. You will see this in both new and old Macbooks where write speeds obviously differ from 128GB and 256GB. Anything above 256GB won't differ.
Example:
128: http://www.nas-storage-blog.com/wp-...een-Shot-2013-06-22-at-8.30.35-PM-295x300.png

I think he's talking about the 13"S but anyway, yes even if both the Air and rMBP used a Core i5, at the moment the current line of the 13" rMBP has a chip that is no match against the U Series that ships with the Air, however they're using the U series in the new rMBP.
And Air actually maxes at 8GB now.
I disagree. The processors in the Air are low voltage versions that run at lower clock speeds and cannot harness the same amount of power. The processors in the 13" rMBP are big boy processors and are still more powerful. I had a Haswell MBA with the i7 and 8GB of RAM, and even with the HD 5000 it did not run Starcraft 2 very well and got extremely hot during gameplay. My 13" rMBP with the i7 and HD 4000 performs much better on the same game.
Could be read wrong but I mean't no match as in it's better and not to be compared to the U series. It just got interpreted the opposite way, which is fairly easy with how I structured that sentence.
Also, they will be using ultra lower power processors for the next rMBP.
I am very tempted to purchase a high end rMBP 15. I am very disappointed because I have been waiting for several months for a refresh. I return to college in late August and I need a new laptop. I feel like Apple will not refresh the MacBook Pro for back to school, which is very aggravating. Please share your thoughts, opinions and advice.
Just get one now. You'll be happy you did and if you shop around a bit you will also save a lot of money compared to buying a new haswell machine at retail when they eventually do come out.
Well maybe the haswel rMBP will get a dGPU (on high end models). Looking through the "leaked" benchmark of what appears to be a haswell rMBP we find that it has a 2.4ghz processor (6mb cache) with iris pro. Now I assumed that the higher end models would have a higher clock version of this. Then I realized: that's the highest clocked 47w iris pro cpu avaliable.
The clock speeds are:
2.4
2.3
2.0
Now, for apple to keep it's three processor options like the current rMBP, the 2.4 would have to be the top end version. This does not seem likely at all, as it only has a 6mb cache and is the same clock speed as the current low end cpu.
Apple will have to either have the max be 2.4ghz and use slower CPUs for the lower end models (maybe they could overclock it..?), only offer a 2.4ghz model, OR use the 2.4ghz with iris for the base model, and have the hd4600 versions + dGPU route for higher end
This might be good news if you want a dGPU, however, it does mean that if they go this way, you'll have to pay the price for the higher end. And the difference is likely to be nelgiable if it's using a gt750m unless it has 2gb VRAM
The first option is very unlikely as basically it is a reduction in cpu clock speed and graphics. Ouch.
It would make sense for that to be the lowest end, $1799 or $1999 model. However as some have said, apparently the cost of iris vs the cost of dGPU + 4600 is the same. That being said, I could totally see apple slightly cutting their margin on the base version, while severely marking up the dGPU version, even though it costs the same to produce.
Interesting

@applepie555 You do realize that the 2.4 Haswell performs close if not better than the 2.8 IvyBridge right?
And if you're going to buy one, do it before BTS expires on September 6... Regardless, of the Haswell update.
I think you're on the right track, but I don't think it's either/or. History yields some useful lessons here, and in particular, the 2009 MBP summer models are illustrative. The baseline configuration contained only integrated graphics and was coupled with a $300 price drop. In this case, I would still expect the baseline 2.4 + Iris 5200 to come in at $2199, due to the high cost of that chip. This will still have inferior margins compared to today's Ivy Bridge + dGPU baseline model, but that's typical for new model introductions where you make up for the margin loss by volume.
Then, for the high-end stock configuration, you'll be able to get higher clocks and the dGPU. You cited those high-end configurations having inferior battery life, but Apple estimates have always been based on the iGPU. As such, they'll still be able to market the same sort of battery durations.
Obviously this is educated speculation. But I can't come up with any other approach that makes sense from both the business side AND the marketing side. It's not like they can get away with going from 2.4 to 2.0 clock speeds on the baseline model. (If you recall, that is precisely what they did when moving to quad core, but they were able to market that as a big increase in speed.) We have seen small drops -- like from 2.53 to 2.40 in Core Duo to Core 2 Duo if memory serves -- but nothing that big. So, if cost and marketing are the drivers, I can't see any other viable approach other than the one I spelled out above.
I would love to have a 15" without dGPU, just with Iris Pro.
I'm not a gamer, but use Photoshop (which supports OpenCL). Together with the edram of the Iris Pro, it'll be screaming fast for my use!
The UI will be as responsive as when running off the 650M in the current ones - just with WAY better battery life and much cooler.
So I really hope that Apple will release one without dGPU for people like me, and then an option with dGPU for you gamers.
We've seen that before with Apple, and I Think se can see that again!

I'd like to see this too. Just hope Apple doesn't only offer iGPU only with just the lowest clocked CPU.
That's probably exactly what they'll do (per my post above). The Iris 5200 versions top out at 2.4Ghz (4950HQ). The substantially inferior HD 4600 versions top out at 3.0Ghz (4930MX). Since there's no way you'll see a standalone HD 4600, I think the most likely scenario is a 2.3Ghz (4850HQ) or 2.4Ghz (4950HQ) with the Iris 5200 in the low-end, and dGPUs (perhaps starting with the 4900MQ) in the higher ends.
