Chrome books are interesting but the OS is a big problem. Great platforms for Linux though. Even the ARM based machines have potential as Linux platforms. There are however real problems with Chrome books that make them a bad buy for many uses. One is the paltry amount of flash included.And the irony is that the high end chromebooks with Intel CPUs will actully be more powerful than Macbooks with Apple processors.

It was painful only for people that wanted it to be painful. People that hot with the program never looked back.Well you just made his point stronger. Switch to a different procesor was very painful even though new CPU was more powerful.
This is an entirely different situation. First we aren't talking the entire product line, at least not anytime soon. Second you make an assumption that the machine would be slower than the Air or iPad. There is a very good possibility that it won't be overall. Third things like Chromebooks, iPads and other devices have clearly demonstrated that i86 support isn't a big deal anymore. This is perhaps the biggest factor here, nobody cares about i86 anymore. It is all about web access, E-Mail and other canned solutions.Now imagine switching to a new CPU again but this time to a slower one.

It's not flawed. You have to include all the cores. That makes up the whole processor. If Apple can't design a multi-core processor then it'll never catch up to the performance of Intel.
Mainly because it wastes space and transistors in a laptop portable chip which is not a good thing.Why wouldn't it be the 'best solution' assuming Apple licences a GPU core from a big name and couple it with their own ARM64 core?
adopt the standardised platform that AMD is promoting then combine it with a high performance dedicated GPU from nVidia or AMD? Lots of possibilities - heck, for many years there were ARM based CPU's shipping in computers and laptops from Acorn so it is possible and given the fact that Samsung manufacturing process is almost as advanced as Intel I could see Apple keep up with Intel especially when one considers that since ARM64 doesn't have all the baggage of CISC it should be relatively easy.
That simply isn't true. The vast majority of software on the Mac is threaded, uses processes or in other ways can make use of those cores. Sure you can find examples of demanding apps that aren't threaded but the user picking up a Mac OS based machine will not have a problem with the included apps.Good luck with all your cores on a single-threaded application. Which are still a majority.
Wrong again. These programs are highly threaded or spawn other processes. It is fair to say that if you went back to a single core on a Mac you would be very disappointed.More cores won't give you faster browser or office performance. We are talking normal usage here, not embarrassingly parallel algorithms.
While I have to say Geekbench has no place in this discussion, you can't dismiss the importance of cores with a modern operating system and apps. Just about any app accessing the web these days is threaded.Taking multi-core performance as the main score, especially on a series of micro benchmarks like Geekbench, is trivialising the discussion.
So would an iPad so what is your argument? Apparently you just don't understand how modern operating systems and apps work. Right now 4 cores seem to be the sweet spot for general interactive use. Put somebody with a little skill behind that machine and 4 cores isn't enough. This applies to Intel as well as any other architecture out there. It is extremely easy these days to slow a dual core machine down to a crawl.I have access to a supercomputer which contains more then 18000 cores. I bet though, that a MacBook Air would beat it in a browser benchmark...
Well, it's just a rumour, but if it turned out to be true, that would be it for me as far as buying an Apple computer.
ARM for iToys and iOS; Intel and OS/X for laptops and desktops, okay, Apple?
Apple switched to Intel in 2006-ish.
Not anytime soon. People in this forum can't seem to grasp the idea of a new class of devices.You sound so high-strung it's quite funny. Obviously Apple won't convert the entire product line to ARM. The world still needs trucks for heavy lifting.
Exactly, the bulk of Apples sales go to machines with some of the lowest performance Haswell parts out there.Netbooks were bad but gave birth to the Ultraportables which are the top dogs in contemporary mobile computing.
Here again people seem to forget that A7 only runs at around 1.3GHz in today's machines. Bump that speed into comparable Intel territory and the performance can easily double if the I/O is adjusted to keep up.ARM is continually evolving and the performance will eventually be comparable to a low-end i3 or even i5 in the future whilst offering way more battery life and less heat. And also allows the construction of lighter enclosures.
Or they could just shut up! Clearly many of them have real i86 needs but more than a few don't have a clue. The vast majority just don't care about i86.The rest of you 'REAL' laptop users can keep buying your pros or switch to windows like you're all threatening.
Intel was behind PPC and AMD at one point but they improved. To think ARM won't is very short-sighted/narrow-minded.
even if this rumor is 100% true it didn't imply that Apple was leaving Intel behind on all machines.Agreed. Intel runs great, until people stop developing for it and/or the difference in compute power is extremely lesser then ARM in the future, we should stick with it. I'm about 75% Mac, 25% Windows, but if Apple moves to ARM, that percentage will change greatly.
More importantly the important apps that people buy these sorts of machines for are threaded or in other ways take advantage of cores.That's not as true anymore as it used to be.
1. apps are more parallelized than previously (modern APIs make it a lot easier to do correctly than in the past)
No to mention those apps do use threads.2. modern ARM CPUs haven't been standing still and are now fast enough for the single core tasks that remain. E.g., Gmail works great on my iPad with A7 processor. Office runs OK on Surface RT devices which use ARM processors and would run better on an A7 much less on whatever CPU an ARM-based laptop would use. (Not to mention Office for iPad which runs great on an A7 according to the reviews I've seen.)
It is doubtful of an entry level machine. I do believe that this was the biggest mistake of the reporting. I can't see Apple interested in anything other than a single SoC for this class machine. They could however group CPU complexes into groups of four dirt of like Inteks approach with the new XEONs that use groups of five.I do doubt that even if Apple does this, that they would put 16 cores into an ARM-based machine.
I just don't think there are 16-cores of stuff -- 16 parallel threads of execution -- to run except in relatively rare circumstances. More like 6 or 8 cores... maybe even 4.
What is the cost of the current i5 in the base MacBook Air and four A7s? I wonder what four A8s will cost. The article mentions that there would be four to eight A series processors.
The concept doesn't even make sense. Why would apple put 4-8 SOC chips on one device? SOC = system on a chip. That means that a bunch of the features on each chip will be redundant.
The problem is that most people mis the biggest reason as to why Apple would do this.
I should have asked how much "4-8 64-bit ARM Quad-core processors" (quoted from the article) would cost. I replied to someone who said there would be no price reduction for an ARM-based OS X device.
This would only work if its easy for developers to port their code to the arm based systems, and there was no performance degradation.
It also lights a fire under Intel. Do you think Intel is going to be telling Apple about another processor delay if they see Apple with ARM PCs ready to start manufacturing at any time. Apple might intro an ARM laptop at the low end of OS X portables, and let Intel know the same thing could happen to the far more profitable mid and high end products as well if Intel doesn't pick up their pace.
Why do so many people think Intel really cares about Apple? Apple Worldwide market share in computers is just 5%. Companies like HP, Dell, Lenovo, Asus etc. buy a lot more processors from Intel than Apple.
What if apple were to use both processors and have an ios like low power mode? They could also provide auto switching like the do with the GPU.
Well, this is disheartening news, if true.
I think it would be a mistake for Apple to do this, but I wouldn't be surprised if they did it.
I just don't understand what the hell is going on over there these days.
It isn't a typical mistake, CPU performance can scale with clock speed if the supporting circuitry keeps up.
This is baloney, Cyclone has proven itself in a wide array of workloads on the iPad.
Well for one it isn't that bad considering the size of the chip and two you assume it won't get better.
Apple can easily address this with improvements to the Memory interface and the caches supporting the GPUs. RAM and caches play a significant role in keeping Intels cores running and are in fact bottlenecked through the RAM interface. In Apples A7 case the bottleneck is significant due to the GPU load on that interface.
In a nut shell the A7 cores could do much better with improvements to memory and caching without touching the core at all. However I don't think Apple will leave those cores untouched in future A series SoC.
Maybe to some extent but you fail to realize that the cores are small allowing many onto a piece of silicon. Cores are an advantage in portable devices because in a good desiring they are near zero power when not in use.
Well that we agree with. Get away from Geekbench and we see that A7 is in fact a good core. It is a core that needs a much better I/O subsystem to deliver goi results.
This isn't true either. Years ago Global Foundries was touting ARM core running on what is now an old process, they where able to hit very high clock rates on those processes. Currently Haswell does well because Intel does have a process lead not an architecture design lead. Intel is also blowing its chances to maintain that lead at 14 nm so we could very well see 14 nm ARM based machines early in 2015.
Oh and by the way the ability to sleep a processor is far more important these days than a slight power advantage at full performance.
It is also a mistake to assume that one app is important to most users. On the contrary most people do multiple things at the same time on their machines even if the don't realize it. Overall system performance is enhanced by more cores.
Obviously the benefits of cores depends upon the application but you have to separate that from the benefits to the system. Most user apps though do benefit from more cores as they are multithreaded or use supporting processes. The proof is in the pudding and the fact that nobody is going back to single core machines.
It isn't an advantage at all for apps, it instead allows Apple simple hardware solutions to power management. In fact due to Apples low clock rates used to manage power single threaded apps are at a real disadvantage on iOS devices. This is why Apple pushes GCD and other technologies that use both cores.
The number of cores has no bearing on parallelizing bugs. More cores just means the bugs pop up more. In general though many of the parallelizing features in iOS reduce the complexity for developers.
Well no, their engineers failed to deliver the cores promised, a big difference. In the end they had to market what they had. By the way the story is much different when BRAZOS is compared to ATOM, in a real sense AMD hit that one out of the ball park. AMD hasn't completely failed in the market, they just haven't competed well at the high end. In the middle and low end I have no problem with AMD's chips. Mullins, Kaveri and the other recent chips are very worthy of consideration.
----------
Then you don't understand what is happening here. In a nut shel to continue to innovate they need access to the silicon! It really is that simple.
What choice do they have if Intel won't open up its silicon. Their only choice is AMD if they stay i86. Go to ARM and they have basically unlimited solutions they can leverage. Everything from in house solutions to products from AMD, Samsung, TI, Qualcom and a long list of others. Companies by the way willing to partner with Apple.
Frankly it would be a mistake not to go ARM long term.
Try a little harder. Look at a motherboard from an Apple PC from 10-20 years ago an imagine all of that innovation built into one piece of silicon. That is where the industry is going.
This should be an obvious move. Look at the benchmarks and their progress. We'll use geekbench for simplicity, not perfect, but it's well rounded. The A7 scores about 2,600, double the A6's 1,200-1,300. Even if Apple did nothing to improve the ARM architecture, the A8 is expected to have a quad core with the die shrink to 20nm. Doubling the die size to fit the power availability in a laptop would yield 8 cores. 8 x 1,300 (per core) is about 10,400. That easily beats the performance of the current Retina Macbook Pro with about 7,000. If they double the core clock to 2.6Ghz, like some rumors say they have, they could beat the Core i7 with the same number and only 4 cores, giving good single-threaded performance. That's all assuming Apple hasn't done anything to improve their architecture, which they most certainly have.
Intel's days are numbered at Apple.
The 64bit Dual Core A7 running at 1.4Ghz gets around half the geekbench score of the dual core i5 in the MBP. If they use a quad core it would be on par, then if they are to use 4-8 of them, it will be 4-8X more powerful. That has to be enough extra power to real time translate Intel processor applications to run on ARM would it not?
----------
haha
----------
If they make a version of Final Cut Pro, and get Adobe to translate all of their apps, it could push devs.
You have no idea what you are talking about the i7 in the MacBook Pro gets around 15,000 on geekbench not 7,000. You are way off base.
This should be an obvious move. Look at the benchmarks and their progress. We'll use geekbench for simplicity, not perfect, but it's well rounded. The A7 scores about 2,600, double the A6's 1,200-1,300.
