And for the sheeps who thinks a8x can match this, look st the preview on anand. This thing is on par with surface pro 3 and runs circles around any ARM device including iPads. But keep pretending to be an analyst doe.
It depends upon how you Marie performance. On a performance per watt basis it is a very competitive market. In the case of Apple A8X they appear to be able to safely rise above all completion in that regard.I'm always amused by comments like these. I realize that people think CPUs are all the same but ARM isn't even in the same universe as Intel when it comes to performance.
Oh the real work argument which of course means nothing. The fact is one can put more cores into a given ARM SoC and that works out very well for some use cases.I don't mean surfing the web, wandering around FaceBook, writing an email or doing something frivolous while waiting for your coffee at StarBucks. I'm talking real work most people do on a notebook computer.
OS /X is UNIX and iOS is a subset of that so you blow all your arguments to hell because you effectively verified that ARM is very capable of running Unix. The fact is it runs LINUX too.ARM is great at power management (RISC Instructions) but sacrifice's performance for that power management. Your iPad and iPhone run a lite version of OS X in a very tightly controlled environment with limited multitasking.
If you have enough cores it won't be a problem. Many of the program you mention are heavily threaded or make use of sub processes so performance is dependent upon having enough active cores to keep all of those threads up to date.Now imagine that same ARM processor in a MBP with a full version of OS X running many heavy duty applications (think Photoshop, X-Code, Word, Excel, Dreamweaver, etc...) all at the same time. ARM based CPUs are just not designed to work in that kind of environment.
Maybe not. There is some speculation going around in design circles that Apple has achieved transistor densities with A8X exceeding what Intel is getting at 14 nm. I have not seen that verified but the idea that Intel has a massive lead here is asinine. Further Intel has yet to really deliver with respect to 14 nm, a trickle of processors is not a sign of a mass production ready process.So you think Intel is struggling? Intel has the most advanced and cutting edge R&D facilities in the world when it comes to microprocessor technology. Nobody comes close. They are years ahead of everyone else.
Yep engineering trade offs. No surprise there. However Intel has hurt themselves and frankly the entire i86 industry by not transitioning to a clean 64 bit platform and deleting allof the legacy hardware that support modes no one uses anymore.Intel has had to maintain the same instruction set while moving forward in a world where people want insane performance out a multicore chip with all day battery life in a tiny package.
Well no! You would expect power to go down with every process shrink. As for performance going up that has certainly happened but the gains in the CPU have been minor compared to the efforts they have put into the GPUs. The fact is we are seeing disminishing returns with respect to the effort required to get better IPC counts. This is in fact why we have dual and quad core CPUS and in some cases SMT. Trend highly favor the smaller cores that ARM can provide as this allows many to be placed on a single SoC.When you look at Sandy Bridge, Ivy Bridge and Haswell, their performance has gone up while power usage has gone down. That is impressive advancement given everything that Intel has to maintain.
ARM is perhaps one of the most unlimited architectures or better said ISA out there. The designers are free to produce an ARM chip that is as sophisticated as they need or are capable of producing.I think the limits of ARM will hurt them in the end. I think that Intel's R&D and industry might will move their chips to match the power efficiency of ARM with that added performance and instruction compatibility that people want (even if they don't really know it).
You think wrong. Why? Because of the fact that the SoC is where manufactures like Apple now put their innovations. The days of gluing together a few TTL chips to provide unique functionality is gone as is the design of custom LSI chips to solder onto a motherboard. You can expect to see Apple putting more and more custom functionality into their SoC, not because they want to get away from I86 but rather because they need that chip to put the custom circuitry that makes their products competitive.I think devices like the iPad and iPhone will eventually move to Intel processors.
Here is an older article with more information.
I'm more interested in how the integrated graphics compares to Haswell.

That is the CPU, the GPU is limited to 850MHz.Not really. It'll scale itself up to either 2 or 2.4GHz if it runs into a demanding application that needs more power.

Eh, Itanium didn't sell all that well. x86-64 got too popular too quickly for it to catch on. It was a clean break from x86 (to the point that it had to emulate it and THAT performance hit was massive)...Yep engineering trade offs. No surprise there. However Intel has hurt themselves and frankly the entire i86 industry by not transitioning to a clean 64 bit platform and deleting allof the legacy hardware that support modes no one uses anymore.
Frankly the only reason we have Arm in an iPhine is because it is the only play in town right now for custom SoC designs. Intel seems to be highly reluctant to enter that market and AMD is late to the party. Even then the Arm cores take up a trivial amount of space on Apples SoC highlighting just how important custom circuitry is on these chips. More than half (including the GPU and CPU and cache) of Apples A8 is unidentified in the latest chip tear downs. It is Apples ability to use half the chip for their own specialization that keeps i86 out of iPhone.
I believe benchmarks have shown them to be less powerful than the current MacBook air's hd 5000So... relatively weak (but power efficient) processors... and Retina in the new Macbook Air?
I hope those integrated Intel graphics are hella powerful.![]()
Why do so many try to muddy the discussion with nonsense like this? It is understanding clock speeds that has people worried about this chip in a fanless design. Especially when combined with Intels questionable use of processor power ratings.Why do so few people understand clock speeds?
Actually you can't rationally compare processor families with out knowing the clock rates of the chips involved and how much they get done per tick. In this case the rational comparison is between Broadwell and Haswell. If Broadwell only gets about 5% better performance over Haswell per clock you have a real possibility of a performance regression relative to shipping MBAs.When comparing among different processor models, they mean absolutely nothing.
Again why muddy the water with such an asinine comment? The only comparison that makes sense in this discussion is with respect to the current MBA as this machine is apparently a replacement or upgrade for those machines. Given what is known at this point there is a real potential for a performance regression especially if one engages in more demanding work.Do you really think a first-gen 1.3GHz Intel Atom would be more powerful than this chip? No, of course it isn't.
We aren't even sure about the GPU boost nor how sustainable GPU performance is. Granted I'm the first to knock Airs with respect to GPU performance but GPU's are very power hungry. I can easily see a GPU using up that 4.5 watt power budget all on its own.This isn't necessarily a downgrade - especially given the GPU boost.
We'll have to wait and see what the benchmarks are like before declaring it a downgrade, sidegrade or upgrade.

I don't mean to call you out directly, as you aren't the only person to attempt to make a funny. It just grinds my gears.
Aluminium and aluminum are both accepted pronunciations and spelling of that metal. Aluminum is just the North American English version. It appears Webster's dictionary may be to blame.

And I am saying this as an American...

Here's how it works:
- The 12" MBA has a keyboard and trackpad but no screen
- If you want, you can plug it into your own monitor and use it like Mac Mini
- Or you can slot in an iPad Pro and use that as a monitor
- With handoff, it doesn't matter if you're using the iPad Pro as an iPad (iOS), or the MBA as a desktop (OSX).
With the on SOC GPUs and DSPs being used more and more for tasks that are able to be done in parrallel, we are at a point were the CPU is becoming less and less important in the scheme of things. In that regard, Intel is fighting a losing battle since Apple is no longer just fighting to get the CPU faster and the CPU is less and less important to them.
As for Windows applications going to ARM. If develloppers support standard libraries like OpenCL, they mostly don't rely on the CPU to do most of the job anymore. In such a case, those companies can easily port their software to where most of the untapped market is right now : ARM.
Is power consumption really such a big deal on the Mac Mini? Or did you wanted slimmer Mac Minis?Damn why didnt the new mac minis wait for these.
I will be waiting broadwell macbook pro. or perhaps skylake, with 5k capable display output.
1) CPU will be always important... You never know what will that illogical creature, some call it 'user', want to do with your hardware. Therefore you can't make one-purpose ICs. Yes, number of them WILL increase. But there has to be something to drive them and perform tasks which can't be done with implemented with available ICs or it would take longer with them.
2) You'd have to recompile all these libraries. And professional software often has optimizations written in assembly...

Apple wouldn't seriously put the 800MHz processor onto a MacBook Air. Intel was once king of processors, now I'm not so sure.
USB or TB drives certainly make more sense with respect to the desktop. This is actually a flip in my opinion from a year or so ago. In this sense I'm talking about bulk storage, you still need enough internal storage to run all of your apps properly. It is the advent of TB and USB 3 that makes external storage in all its varieties acceptable. Without those standards I couldn't support the use of external storage on the desktop.Why not just buy a usb drive? Done and done.
What's the point of having so much storage inside the machine?
Many of those software and libraries are being ported to more open standards, less dependent on architecture and recompiled already. If the money is there and they got tools to make this easier, most of them will end up on ARM in the next 2-5 years.
Apple has been very good at providing tools for cross platform development. If they spend money on that, and then can, the transition would be painless.
I didn't say it wasn't important, but how is it important to 95% of tasks is what determines its true usefullness. The CPU's job will be more and more as some kind of high end traffic analysist that identifies/structures and directs traffic to the appropriate resource and while "bored" does all the rest of the general tasks required on the system ;-).
Optimisation done in assembly will be less and less usefull as processing is paralelized to the GPU, DSP's and other specialized processors.
Its obvious from Apple that being liberal with gates is the way to go for overall performance in the future. The SOC has in fact become the motherboard!!
