Looking back, MacBook abandoned intel and the chip completely turned to self-developed architecture. Although the performance has improved greatly, the real unique advantage must be " energy efficiency is better than ".
As we all know, the battery life of Windows laptops has always been seriously false. Many thin and light notebooks claim to be able to support 8 hours of office work, but in fact, they are actually used, and the battery life of the power is often less than 4 hours.
and after unplugging, the CPU will still reduce the frequency and cannot perform at full health. A battery life of about 4 hours cannot bring a sense of security. At least it can last for about 8 hours before we dare to go out without the power cord. The battery life of
is exactly the strength of MacBook. With the support of ARM architecture + TSMC's advanced technology, the energy efficiency of M-series chips is beyond the reach of the X86 camp. Because of the high energy efficiency of the chip, MacBook Air can work normally without fan cooling, and the maximum battery life can reach 18 hours. Even after power is unplugged, the performance will not decay, becoming the true mobile workstation .
has strong performance, low power consumption, no noise, and can last for one to two days, how perfect it looks. If you do not consider application compatibility issues and the high learning costs of macOS, MacBook is the most ideal thin and light notebook in the minds of consumers. The question is, when will the CPU of Windows laptop reach M1 level?
First of all, it is important to understand that simply speaking about the absolute performance of CPU, M1 has no obvious advantages. According to the Geekbench 5 running score, the M1's single-core CPU is 1730 and the CPU is 7833 points. What is the level of this score in 2022? Considering that the price of the MacBook Air 2020 model is still between 6,000 yuan and 8,000 yuan, we are too dying if we don’t need to card in terms of budget.
Comparison of the mainstream CPU of thin and light notebook in 2022, the running scores of R7-6800H in Geekbench 5 are 1520 and 9410, i7-12700H are 1607 and 12103, and i9-12900H are 1753 and 12662. It can be seen that the single-core CPU of chip is leading, but the CPU multi-core score is obviously behind - after all, M1 is just an 8-core CPU, and two fists are hard to beat four hands.
The problem is that it is the CPU energy efficiency ratio of the PC camp, and when can it reach the M1 level? Here we have to come up with classic old pictures. At the M1 press conference, Apple used a set of data to prove the energy efficiency advantages of M1. The reference object was "the latest CPU on the notebook at that time". When
achieves the same performance, M1 consumes only 25% of the latter's power. At the same 10W power consumption, the M1's performance is twice that of the latter. Although it is suspected of playing text games, at that time, the ultra-high energy efficiency ratio brought by the ARM architecture could indeed allow the M1 chip to perform well under the premise of limiting power consumption.
However, it should be noted that the opponent Apple chose at that time was most likely not AMD, but Intel. In fact, when the M1 was released, the Biba evaluation room conducted a running score test. They found that in the R23 multi-core running score test, the M1 used 16W of power consumption and ran a score of 7629. With almost the same power consumption, M1 is only less than 15% stronger than R7-4800U.
According to the test of digital enthusiasts, R7-6800H has surpassed M1. When the CPU package consumption of 15W, the R23 multi-core score reaches 7836 points, and the energy efficiency exceeds the M1 chip. If the power consumption limit is released, the R23 multi-core R7-6800H can run to 13000.
From this perspective, the CPU of Windows laptops, both performance and energy efficiency, has surpassed the M1 chip.
: Let me say something off topic. Apple's opponents will not sit still and wait for death. After MacBook switched to ARM architecture, the PC chip industry also began to infer crazy inversion.
According to the data from Geek Bay test, the i9-12900K has a single-core IPC increase by 45% compared with the 10th generation i9 and a multi-core IPC increase by 51%. And more importantly, in the R23 test, the small core on the 12th generation Core used 17.3W of power consumption to exchange for 7336 multi-core running scores. In contrast, the R23 multi-core running score of M1 is 7823 and the power consumption is 15W - with a small core alone, it can be comparable to M1.
Of course, the above data is just a theory, and the actual situation is far more complicated than the data. The M-series chips are Apple's own dedicated chips, while Intel and AMD are general-purpose chips, and the system optimization efforts are not at the same level at all.To give a very small example, according to the test of Geek Bay, the power consumption of the M1 chip can even be as low as 0.02W during standby, and basically no power loss is lost.
and PC is not so good for optimization. Even for low-voltage U, the standby power consumption is more than 1W. And not only that, in most light use scenarios, the power consumption of chips on the PC is several times that of M1. This leads to a problem: for ordinary consumers, although the M1's running score and energy efficiency do not have an advantage, it has an unexpected battery life experience.
Finally, let me talk about my point of view: the CPU of Windows laptops has long reached the M1 level. However, a laptop equipped with a Windows system and an X86 processor makes the battery life experience difficult to surpass that of a MacBook. Maybe we can only see this day when the PC also turns to ARM architecture. What do you think about this? Welcome to discuss it together.
