Hello Everyone, how are you all? Hope everybody is well. From now on we come to you regularly with new tunes. And in order to keep up with this new topic and trend of service, today I have come up with a brand new topic with you. Today I will talk about A Brief History of Mac CPU Architecture. And you can know all the new information through this tune.
Apple Macintosh has used three different CPU architectures over the last 36 years, and they are currently in danger of migrating to a fourth CPU architecture. And while rumors are circulating that ARM will migrate to architecture, let’s not get into the brief history of Mac’s CPU architecture now.
Motorola 68 K (1984-1995)
In 1974, Apple released the first Macintosh computer (known as the Apple Macintosh). It uses 8 MHz Motorola 68000 CPU. And during development, the Mac initially used the 8/16-bit Motorola 6809 CPU as the prototype. However, after a designer observed the graphics routines to create the Apple Lisa based on the 68000 CPU, a more expensive 16/32-bit 68000 CPU was used. Since then, the Apple Lisa has used a 68000 CPU of 5 MHz. But the new Mac Prototype is capable of running at 8 MHz. And Steve Jobs was very happy about this success.
In the following decade, newer models of Macintosh computers used the Pure 32-bit 68020, 68030 and 68040 chips. These chips also improved speed and performance over time.
Overall, Apple has used 68k CPUs in at least 72 different Mac devices. And the latest Mac model of this CPU was the 1995 PowerBook 190 device.
In the late 1970s, the computing industry began to turn away from the CPU architecture of the 1960s due to new trends such as Reduced Instruction Set Computing (RISC). The new type of CPU architecture ensures a more powerful and faster CPU. In its aftermath, Apple has explored various RISC CPU options. But has finally struck a deal with IBM and Motorola to design a simple CPU platform. And these three companies decided to reduce their dominance in the Microsoft-Intel market (also known as Wintel).
Eventually, the PowerPC architecture was created. It was first used on IBM’s workstations and later in 1994 on the Power Macintosh 6100. Next, Apple designed a 68K emulator that included in every copy of the Mac OS. And this was done because the new Mac devices can use almost all the software developed for the old 68K architecture seamlessly.
Over the years, Apple has released about seven different Mac models, using the 601, 603, G3, G4, and G5 series chips using the PowerPC CPU. And the clock speeds of PowerPC’s CPU have improved a lot during this time, the clock speeds of CPUs were improved from 60 MHz to 2.7 GHz. Then, Apple’s final PowerPC model is the Power Mac G5, which was released in November 2005.
Intel x86 (2006-present)
In the mid-2000s, Apple began to think a little differently because of its reliance on the PowerPC CPU. Delays in producing and designing new PowerPC chips have made it difficult for Mac devices to maintain speed parity with Intel-based PCs or CPUs, which is very important. Also, due to the G5 generation, the PowerPC chips became very backdated, and generated a lot of hits that caused the laptop to turn off and run cold.
So, when Apple announced the use of Intel chips at WWDC 2005, critics were both happy and surprised. For many years they had advertised PowerPC as superior to Intel in advertising and they would be switching to Intel chips which actually seemed like a lifeline for Macintosh. As a result, Mac CPU performance has quadrupled overnight. And the first Intel chip Mac models were announced in early 2006: iMac and MacBook Pro.
And Apple has included an advanced emulator technology called Rosetta in Mac OS X 10.4.4 to protect the compatibility of software between their different generation devices. It can translate PowerPC’s code to Intel CPU at magic speed.
And not long after that, developers began distributing their programs to the public binary. Which can be run on PowerPC or Intel Mac, which made the x86 transition much easier. After that, Rosetta gradually removed from Mac OS X which started with Mac OS X 10.7 Lion version.
Apple has released at least 60 Mac models since 2006, using the Intel CPU. Although the final model of the Intel Mac has not finalized yet, many experts have claimed that it is expect to arrive later this year (2020).
At the moment, Apple’s Intel-based Macs are selling well and probably already have a roadmap for building a powerful CPU. However, rumors are rife that Apple will soon switch its Mac devices to ARM-based CPUs. So this is going to be the third system architecture of the Mac device? – If so, why?
Since 2010, it has gained experience designing its own ARM CPU-based system-on-a-chip (SOC) packages for iPhone, iPad, and Apple TV hardware. As a result, Apple has made amazing progress. Moreover its speed and performance have improved dramatically per watt, some iPads are now competing with MacBooks single core performance. Then, comparing Intel’s level performance with ARM chips will eventually replace their Mac CPU architecture with ARM chips.
So according to ARM’s more competitive performance, Apple will have the unique advantage of switching to the CPU of this architecture with more efficiency and control. Apple has already started packing a number of features for this CPU architecture. Such as faster photo processing and AI face recognition in the CPU of this architecture that can implement Apple’s specific design goals. In addition, if Apple uses their own chips for Mac devices, they will be able to create them according to their needs, and there are some additional benefits.
Also, instead of buying chips from Intel for Apple, they can produce the chips themselves at a much lower price. And this will make Apple’s products more profitable, which is very good for their bottom line. Moreover, if Apple wants to move forward in this direction. We hope that in the near future we will get a cheaper Mac device through this cost saving.
Moreover, the developers will benefit a lot as a result. This is because app developers for ARM based SOC for Mac devices will be able to easily port their iPhone and iPad software to Mac platforms. And they will be able to easily develop software for all three platforms while maintaining the same feature.
Now, the only question left is when will it happen? We expect Apple to use the new architecture’s CPU by the end of 2021. So we’ll have to wait and see what happens. Whatever happens, Macintosh will probably emerge as a unified platform in the future. Even if Apple needs to change more architectures.
So, these are all for today. Stay With us for more update info.
