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. We’ve already talked about processors that have on-board graphics, such as Intel Iris and Iris Pro. What are the important features of a processor? The Mac Pro, last updated in 2013, uses the Romley variant of Xeon. The Mac Pro uses a completely different family of Intel processors, designed for high-end workstations and known as Xeon. The MacBook Air and Mac mini have Haswell processors, as they were released in 2013. The slimline MacBook processor is known as Core M, designed specifically for low power mobile use. So, if you bought it in the last year or so, your MacBook Pro processor is Kaby Lake. 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. Recent Intel CPUs have had names like Sandy Bridge, Haswell, and Skylake.

Intel gives each generation of its processor a code name. However, in an application optimized for multiple cores, you should notice a significant difference between CPUs with different numbers of cores. 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). So, roughly speaking a quad-core processor should be able to process instructions at twice the rate of a dual-core CPU. The other difference is the number of cores in the CPU and the number of CPUs in the Mac. Apple labels the Intel CPUs it uses in the Mac as Core i5 and Core i7 and differentiates them by speed in GHz. Since 2006 all Macs have used Intel processors - unlike iPhones and iPads which have Apple processors. 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. 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. 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. Now, CPUs incorporate short-term memory of their own and, sometimes, graphics processors, or GPUs. Until relatively recently the CPU was responsible only for taking input, executing instructions and passing on the results. Put simply, a processor is the ‘brain’ in your Mac. But that’s not quite true, as we’ll explain below. It’s arguable that processors, or CPUs, are now so powerful that they can do everything most of us need to do at a speed that is more than good enough and so choice of CPU isn’t important.
For many people, it’s the last of those that’s most important.
For most of the Macs it sells, Apple offers a number of different configuration options, including different RAM capacities, storage sizes and disk types, and processors.
