Hybrid CPU technology — the scalable, adaptive multi—core technology that provides greater efficiency and speed to multi threaded processing.
CPU design discovers a new track
Chip innovation in recent times has thrown up a whole new potential in the form of a hybrid CPU core structure. A familiar approach to achieve multi-core and thread efficiency by deriving selective and optimal power access to respond to myriad tasks at hand. Two major chip innovators and makers that have released the tech are Apple and Intel. Apple has incorporated the tech in it’s newest release of MacBooks. This has been done using the smashing M1 or Apple Silicon Chip. Intel has it in it’s Alder Lake CPUs.
Ryzen chips is not far away from launching it’s own chip family based on a hybrid x86 architecture. The new adaptive chips are already duly patented. These could see the light of day soon.
The processor game is on
The fresh generation of CPU design-construct promises to provide a shake-up in the CPU performance benchmarks. In the game are none other than Apple, Intel, and the reigning leader in stand-alone CPU performance — AMD. Apple has already made a kick start with the M1 chip which runs their newest MacBooks. Close on it’s heels is Intel which seeks dominance with the release of it’s Alder Lake series of CPUs. AMD’s Ryzen 5000s are not likely to be overshadowed in performance by Intel’s renewed enthusiasm. AMD’s rocking Zen 3 microarchitecture which is built on a 7nm real estate is the reason for this. However, industry news trickling in suggests that AMD, is not far from announcing a new series of x86 hybrid processors. This comes on top of it’s imminent release of the Zen 4 chip architecture.
The approach and the construct
The hybrid CPU definition arises from a unique core setup developed by ARM holdings. In contrast to the highly successful conventional core setup, the refreshing big. LITTLE core setup design offers expanded headroom for performance improvement.
The innovative core framework allows the system to intelligently assign productivity tasks between two types of cores. This helps achieve optimal core performance.
To really understand the uniqueness of the big-little cores concept, let us first consider how conventional cores function. Normally, a multi-core setup works and performs in a uniform and identical manner. That is, each core is capable of taking up a given assignment. This is irrespective of wether it is complex or simple, and also irrespective of the energy it consumes.
The identical cores in such a setup are capable of attaining the same clock speed and accept any task. It does so for both big and small tasks and does not differentiate between them.
The Hybrid big-Little core
The hybrid big-LITTLE core format is designed to function differently to deliver better performance at lower energy consumption levels based on “task differentiation”. It comprises specific core groups. These core groups, include a number of performance cores and power-efficient cores. The two different core clusters are enabled to accept and complete tasks based on their specific attributes.
The high-performance cores come with a high-speced profile and are capable of attaining higher clock speeds. This means that they naturally consume higher power. These cores take on the more demanding tasks in a multitasking scenario.
The other core cluster dedicates itself to conventional, less intense tasks which do not demand a lot of power. These include emailing, calls, texting, and so on. So, you have an optimal system scenario, in which intense, complicated tasks have a dedicated bunch of cores to themselves, and, simpler conventional tasks are carried out more efficiently by less power-hungry, smaller cores.
Hybrid processor technology uses a composite approach to CPU core management which involves selective power access to enable cores to upscale performance on the fly.
Increasing footprint
This unique, scalable core design technology by ARM has become ubiquitous in the smartphone and portable devices segment. It exhibits exceptional ability to balance device performance and power constraints. This is the reason, it is the mainstay CPU design on the vast digital landscape. Apple has successful adopted this hybrid technology in it’s new M1 chip. Intel has it’s success with the Alder Lake CPUs and is AMD on the verge of presenting it’s new x86 hybrid series of CPUs. This has given us enough computing leverage to get accustomed to till the end of 2022. Till the next improved evolutionary stage of this unique technology takes it’s place.
Expect your Apple, Intel, and AMD laptops, desktops, and other portable devices to deliver more power and performance with greater energy efficiency in the near future.
