As far as the processors on the market now are concerned, Intel and the legendary domestic Loongson are definitely mainstream processors. These processors are high-quality processors that have been polished for a long time. Core i5, as a mid-to high-end processor on the market, has very good performance. It can be said that if you don't pursue games, i5 is absolutely enough or even redundant for your daily work. Not to mention the more powerful i7.
And the self-improvement company you mentioned, I doubt whether it has the ability to independently develop processors. Because the research and development of the processor is not a design that can be completed by any engineer, it must be a work that a team can try and experiment for a long time and invest a lot of money.
That's all.
