Now that Apple has almost completed its transition from Intel to Apple Silicon, with only the Mac Pro yet to transition, the question of which processor is no longer a choice between Intel and Apple. This means that a quad-core i7, for example, can act like it has eight cores, but a quad-core i5 will only be able to use the four cores available to it. So a quad-core processor with hyper threading should be able to execute four times as many sets of instructions in a given time period as a dual-core processor with the same clock speed but without hyper threading. Hyper threading allows the processor to handle twice as many ‘streams’ as it has cores, by fooling software into thinking it has twice as many cores. Xeon processors support more memory than the i5/i7/i9 processors. Xeon – Intel’s Xeon processors are workstation or server processors. This is more apparent on the M-series Macs because Apple highlights the number of GPU cores and this extends as you move up the range.Īpple’s M1 has 7 or 8 GPU cores, the M1 Pro had a 14-core or 16-core GPU, the M1 Max had a 24-core or 32-core GPU, and the M1 Ultra has a 48-core or 64-core GPU. Greater amounts of cache will also help with multitasking, because several tasks can be run simultaneously. Cache is on-board memory and it helps the processor deal with repetitive tasks faster, because information can be held in the memory. The more processor cache you have the better. So while the performance cores focus on demanding tasks there won’t be a hit on power efficient processing, both can happen in tandem. The difference between high performance and efficiency cores is that the efficiency cores are power saving while the performance cores can be used for more demanding tasks. Apple’s M-series Macs have two kinds of cores: high performance and high efficiency cores. Having more cores available means that your Mac will be able to run multiple processes at once. For example, even the fastest Intel-powered Mac might have experienced slowdowns and performance drops if a system process like iCloud, or the indexing of Photos or Spotlight, was running in the background. Having two types of cores ensures that background processes don’t slow down the computer because there is always enough power available for programs to run. Macs with Apple chips have two kinds of processor cores: high-performance and efficiency. There are other ways in which the M-series chips are more efficient than Intel processors. The 2019 Intel-powered 16-inch MacBook Pro could only manage 11 hours. The 16-inch MacBook Pro has the longest even battery life for a Mac at 22 hours. One advantage of ARM over Intel’s X86 is power consumption, this is evident in the long battery life of the M-series Macs. Many software developers were quick to update their software to run on M-series Macs, though. Apple addressed this with Rosetta 2, which translates the code from x86 to ARM and, with a few exceptions, there was no issue with software written for x86 running on the M1 Macs. Therefore one of the main concerns with the move to M1 (or any variant) could be whether required software is compatible with ARM. ARM and x86 are completely different architectures-which means that they need different code, and hence the operating systems and software needs to be tailored to them. The Apple Silicon is based on ARM, but include a number of Apple technologies (so they aren’t ARM chips, strictly speaking). The Intel processors that Apple used in its Macs since 2006 were x86 chips. The M1-series Macs beat the equivalent Intel models.
