Intel Processors For Mac

Share this review

Starting later in 2020, Apple is making a big change to its Mac lineup. Although Macs have used processors from Intel since 2006, future Macs will begin using Apple-designed chips like the ones in iPhones and iPads. Apple says that using its own chips will improve graphics performance and battery life for Mac laptops and will provide other less-tangible benefits relating to security and privacy. The first Mac using “Apple silicon” will be available by the end of the year (though we don’t know which Mac model that will be), and Apple expects its full lineup of Macs to complete the transition within the next two years.

This sets up a years-long transition period in which Apple supports both Intel Macs and Apple-silicon Macs with new features and software updates for a while but eventually drops Intel Mac support in favor of focusing on the newer, faster models with its own chips. So the question is: In the early phase of this transition, where we know Intel Macs will fade out but Apple-silicon Macs don’t exist yet, is it still a good idea to spend money on an Intel Mac right now?

The answer differs depending on the work you’re doing, but for most people we think it’s still pretty safe to buy an Intel Mac rather than waiting for one with Apple silicon. But we’ll keep this guidance up to date as the transition to Apple chips plays out and as the company makes more public comments about how much support Intel Macs will receive over the next few years.

What’s the problem?

Apple’s processors and Intel’s processors can’t just run the same software. Each uses a different “instruction set,” meaning (very simply) that software needs to talk to them in different ways to get them to perform the same tasks. Because of this, software developers will need to do extra work to optimize their applications to run well on both Intel and Apple processors. Eventually, as Intel Macs age and Apple-silicon Macs become more prevalent, those developers may stop working to make their apps run on Intel Macs at all.

If you’ve been using Macs since the turn of the millennium, you might remember something similar happening when Apple transitioned from PowerPC chips to Intel processors in the mid- to late 2000s. Apple and third-party app developers supported both PowerPC and Intel Macs for a couple of years, but the last PowerPC Macs didn’t get updates for nearly as long as the earlier PowerPC Macs, a development that shortened their useful lifespans. The concern is that history will repeat itself, and that the last few Intel Macs will be worse investments than both the Intel Macs that preceded them and the Apple-silicon Macs that will follow.

While Mac hardware and software is denoted by its stability, the difference here has lessened. The odds of getting a virus or malware with a PC remain higher than with a Mac, but this is more about the numbers game than technology. About 7.5% of the computers in use are Mac, according to IDC, so hackers spend more time and creativity attacking PCs. Mac OS X For Intel. Building a computer with Intel's technology shouldn't prove too difficult for Apple's engineers, but one of the most important factors in the transition to Intel-based Macs will be, as Jobs himself put it, 'making Mac OS X sing on Intel processors'. Intel has provided Apple with processors for its Mac lineup since 2006, a long and mutually profitable relationship. While MacBooks and iMacs lack the marquee appeal of the iPhone, Apple still. The Apple–Intel architecture, or Mactel, is an unofficial name used for Apple Macintosh personal computers developed and manufactured by Apple Inc. That use Intel x86 processors, not verified in body rather than the PowerPC and Motorola 68000 ('68k') series processors used in their predecessors. With the change in architecture, a change in firmware became necessary; Apple selected the.

Most people should buy what they need right now

Our long-standing advice to people who need a new computer right this minute is to buy one. There’s always something new coming around the corner, but you never know how long you’ll need to wait for it or what features it will include. As of this writing, the 2020 MacBook Air and Pro lineups are as good as they’ve been in years, with much more comfortable keyboards than on previous models, more generous storage, and solid performance. Those computers aren’t suddenly bad now that Apple is changing processors, and they’ll be supported with new software updates “for years to come.” Apple won’t say exactly how many years that is (we have some guesses), but Macs typically receive new software updates for six or seven years after their release, and security patches for a couple of years after that.

That said, if you’re on the fence about buying a new Mac—maybe the one you have is working fine but getting old, or you bought a model with one of the old low-travel keyboards and want to upgrade to a better one—you should wait at least six months or a year to see how Apple handles the early phase of this transition. We don’t think the first Apple-silicon Macs will differ dramatically from current Intel Macs in how they look or work, but going forward you can expect Apple to introduce more and more features exclusively for Apple-silicon Macs.

When you should definitely buy an Intel Mac

If you’re looking to buy a Mac desktop instead of a Mac laptop, it’s better not to wait for Apple-silicon Macs. Apple confirmed that it still has some Intel Macs on the way, and the aging iMac is the most likely candidate for an Intel-reliant refresh right now. We also know that Apple’s current iPad and iPhone chips are a better fit for smaller, power-efficient laptops rather than high-performance desktops, which suggests that the iMac, iMac Pro, and Mac Pro will drop Intel processors closer to the end of that two-year transition period than to the beginning.

And if you run Windows on your Mac in any form—either by shutting down macOS and booting up Windows via Apple’s Boot Camp software or by running Windows on top of macOS using virtualization software like Parallels or VMware Fusion—you’re also safer buying an Intel Mac. Boot Camp won’t be available on Macs with Apple processors at all. Virtualization software may be updated to run Windows on Apple silicon eventually, but the Rosetta emulation software that Apple will use to run Intel apps on Apple chips explicitly does not support virtualization. At best, the makers of virtualization apps may be able to come up with their own workarounds, but Windows will likely run slower on Apple chips than it does on Intel chips.

When you should definitely wait for Apple silicon

One thing that Apple-silicon Macs will be able to do that Intel Macs can’t: download and run iOS and iPadOS apps and games directly from the App Store. Software developers can already get their iPad apps running as Mac apps that will work on Intel or Apple chips, but it requires extra effort that most developers haven’t put in.

Right now, it’s hard to think of an iOS or iPadOS app that would be worth delaying a Mac purchase—most productivity apps are already available on both, and the Mac-specific versions will still work better with a keyboard and mouse and be more consistent with the rest of your Mac apps. But it’s an intriguing option for phone or tablet games, and it’s likely to be just the first of a steadily growing list of things that Apple-silicon Macs will be able to do that Intel Macs can’t.

How long will Intel Macs get new updates?

Apple CEO Tim Cook has promised software updates for Intel Macs “for years to come,” but that’s a pretty vague statement to hang a multi-thousand-dollar purchase on. Apple is also notoriously secretive about its future plans. But what we can do is look at Apple’s last processor transition and its current support policies to come up with a good guess.

Apple announced the transition from PowerPC to Intel processors at its developer conference in June 2005. The company then released the first Intel Macs in 2006 and completed the hardware end of the transition by the end of that year, ahead of its original schedule. That meant you could still buy PowerPC Macs as late as 2006. Three years later, the Mac OS X 10.6 update dropped support for PowerPC Macs entirely, and those computers stopped getting new features or access to then-new apps like Google Chrome. PowerPC Macs did receive security updates until 2011, five years after they had last been sold, but no new features or other upgrades.

More recently, when Apple has dropped support for older Mac models in new versions of macOS, it has stuck to its timelines for “vintage and obsolete products.” For purposes of hardware and software support, Apple considers a product “vintage” if it’s between five and seven years old and “obsolete” if it’s more than seven years old. Macs on either of these lists are the most at risk for being dropped when new macOS versions are released; for example, when macOS Big Sur comes out this fall, Apple will drop support for all Macs released in 2012 and a handful from 2013.

Without confirmation from Apple, we can’t say how long Intel Macs will continue to be updated. But in a worst-case scenario, you ought to be able to get at least three years’ worth of active updates and security updates for a couple of years after that. At best, an Intel Mac bought in mid-2020 could see new macOS releases for six or seven years. Apple has also sold many, many more Intel Macs than it ever sold PowerPC Macs, so third-party software developers should be inclined to support Intel Macs for longer.

Footnotes

PC processors from Intel and AMD use an instruction set called “x86_64” or just “x86,” a reference to the original Intel 8086 processor used in some of the earliest modern PCs. Phone and tablet processors from companies like Apple, Qualcomm, and MediaTek use an instruction set called “ARM,” a reference to the company that invented it.

What is a processor?

Put simply, a processor is the ‘brain’ in your Mac. Until relatively recently the CPU was responsible only for taking input, executing instructions and passing on the results. Now, CPUs incorporate short-term memory of their own and, sometimes, graphics processors, or GPUs. In fact, when it comes to choosing a processor for your Mac, deciding whether to opt for one that has an on-chip graphics processor is one of the key decisions you’ll have to make. Macs that have processors with on-board GPUs tend to be less expensive than those that have separate graphics processors, but also are less capable when it comes to things like rendering 3D graphics and 4K video. To further complicate matters, new macOS features like Metal make excellent use of the hardware in GPUs, meaning the choice of graphics processor is almost as important as the choice of CPU.

What processor does my Mac have inside?

Since 2006 all Macs have used Intel processors — unlike iPhones and iPads which have Apple processors. Apple labels the Intel CPUs it uses in the Mac as Core i5 and Core i7 and differentiates them by speed in GHz. The other difference is the number of cores in the CPU and the number of CPUs in the Mac. So, roughly speaking a quad-core processor should be able to process instructions at twice the rate of a dual-core CPU. That’s not the case in the real world, as executing instructions relies on more than just the speed at which the CPU’s ‘brain’ can perform calculations (for example, it’s dependent on how quickly those instructions can be passed to and from the CPU). However, in an application optimized for multiple cores, you should notice a significant difference between CPUs with different numbers of cores.

Intel gives each generation of its processor a code name. Recent Intel CPUs have had names like Sandy Bridge, Haswell, and Skylake. Apple doesn’t use those names, or even talk publicly about which processor is in each Mac, but it’s known that the current crop of iMacs and MacBook Pros have Kaby Lake processors, which were the most recent available at the time they were released in 2017. So, if you bought it in the last year or so, your MacBook Pro processor is Kaby Lake. The slimline MacBook processor is known as Core M, designed specifically for low power mobile use. The MacBook Air and Mac mini have Haswell processors, as they were released in 2013. The Mac Pro uses a completely different family of Intel processors, designed for high-end workstations and known as Xeon. The Mac Pro, last updated in 2013, uses the Romley variant of Xeon.

What are the important features of a processor?

We’ve already talked about processors that have on-board graphics, such as Intel Iris and Iris Pro. These offer benefits such as taking up less space than discrete CPU and GPU chips and Mac’s that use them tend to be less expensive than those with separate CPU and GPU. However, they also tend to be less powerful.

The other key feature of a processor is the balance between speed and power consumption. CPUs that run faster use more energy and so generate more heat. This doesn’t just mean that fans have to run more often, it also uses more power — and if the Mac is a laptop, runs the batter down more quickly. Indeed, CPUs are often ‘throttled’ so that they don’t run at their theoretical maximum, in order to preserve battery life and reduce heat generation.

What about Turbo Boost?

Turbo Boost is a technology introduced by Intel and is designed to allow processors to run at speeds faster than those quoted on your Mac’s label in certain circumstances. Remember we said that CPUs are often throttled to prevent overheating? Turbo Boost monitors the power consumption and heat of the CPU and removes that throttle when it’s safe to do so. So, for example, a quad-core 2.8GHz Mac Pro could run as fast as 3.8GHz in the right circumstances.

Which processor should I choose?

It’s likely that if you’re buying a new Mac, you’re choice of processor will be made from the Core M, Core i5, and Core i7. Not all Mac models offer a choice of all three. The Core M, for example, is specifically designed to minimise power consumption in mobile devices and is used only in the MacBook. If you’re buying a MacBook Pro or iMac, you’ll have the choice of Core i5 or Core i7. Likewise, if you buy a MacBook Air or Mac mini, although those machines use older versions of Intel processors. And, as we said earlier, if you buy a Mac Pro, you’ll be able to choose from Xeon workstation processors with multiple cores.

There are two decisions you’re likely to have to make: i5 or i7 and dual-core or quad-core. Generally speaking, in terms of speed, a dual-core i5 is the slowest and a quad-core i7 the fastest. That, however, is not the whole story. In order to get the most from multiple cores, you’ll need to be performing tasks that really benefit from the ability to execute more instructions simultaneously. So, tasks like 3D rendering, video editing and working with large images in Photoshop will all improve noticeably with a quad-core vs a dual-core processor.

Core i7 processors have two main benefits over Core i5: larger cache and hyper-threading. The presence of a larger cache means the CPU can store more data locally and so spend less time transferring them back and forth to RAM. Hyper-threading allows the CPU to simulate additional cores. So, a quad-core i7 with hyperthreading behaves like and eight-core CPU.

The benefits of larger cache and hyperthreading are seen in scientific applications, where large calculations are performed and their results stored, as well as the 3D animation and 4K video editing.

Integrated vs discrete graphics

Compare Mac Processor Speeds

As we discussed earlier, some Intel processors have GPUs onboard. In some Mac ranges, such as the MacBook Pro and iMac, you’ll have the choice of a model with integrated graphics or one with a separate, or discrete, GPU. If you’re going to use your Mac primarily for playing power-hungry games, manipulating large images, or editing video or animation, you should choose a Mac with a separate GPU. On the other hand, if you’re mostly going to use it for writing, email, social media and editing your own photos, a CPU with integrated graphics, like Iris, is fine.

Can I upgrade the processor in my Mac?

That’s a flat no, sadly. There have in the past been Macs that had processors that could be upgraded, but now they’re soldered firmly in place and so your Apple CPU can’t be removed. That makes the choice you make when you buy your Mac even more important. The good news is that for most users every processor that ships with a currently available Mac, even those that haven’t been updated in several years, is absolutely fine and will run as fast as you need it to.

If I can’t upgrade the processor, how else can I speed up my Mac?

Two of the most effective ways to make your Mac go faster are to install more RAM and swap your hard drive for an SSD. Those both cost quite a bit of money, however. A much less expensive and much easier way is to get rid of the ‘junk’ files that can clog up your Mac. These are installed by applications, or by the system, or downloaded to your machine by websites. Deleting them one by one is a long and difficult process, but CleanMyMac X makes it very easy. CleanMyMac identifies files on your Mac that either serve no purpose, that you’re unlikely to need, or that are large and haven’t been opened for a while.

You can scan your Mac with one click and CleanMyMac will report back to you with the files it thinks you can delete and how much space it will save you — it can be tens of gigabytes. You can then review them and choose which to get rid of or press Delete and get rid of them all. CleanMyMac also makes it easy to uninstall apps you no longer use and removes all their associated files. You can download it free here.

Choosing a processor for your Mac can seem confusing and difficult but it’s not really. Once you’ve chosen the Mac you want, there are likely only to be a few options. And with the help of our guide, you should now know which one is right for you.
