Apple released a new generation of mac laptops on November 11, replacing the Intel chip used for years by their own-developed M1 chip.
Using a 5nm process similar to its mobile phone SOC (system on chip), M1 has 16 billion transistors and integrates the CPU, GPU, and cache into one chip. Apple claimed that M1 performs better with certain TDP (Thermal Design Power) consumption.
So, what is the benefit of an integrated chip? Let me give a simple example to help you understand. The chip is like a restaurant, CUP is responsible to take orders and cook dishes. And combining GPU is like hiring a new chef for high-end special orders, and in this case-graphics. Integrating cache is like this restaurant also building up its own storage unit and transportation system. Overall, these units work together to improve the performance of the chip.
M1 has a tenfold improvement over its previous chips. Especially, the use of ARM architecture shows that M1’s advantage lies in the performance of low-power consumption, rather than just the performance.
Giving up the intel chips shows that Apple is trying to control the rhythm of releasing products and putting the bet on their own developing-groups.
On the other hand, the average improvement of Intel chips is far from expectations. From i7-870 in 2009 to i7-7700K in 2016, the average performance improvement is about only 5%. Clearly, this low pace of development could get in the way of Apple releasing their new products.
Just like Apple said, “this isn’t an upgrade. It’s a breakthrough.” As consumers, we should definitely welcome more competitions like this, as they will largely expand our selections and inject more vitality, as well as pressure in this field.
