On this laptop, it can be seen from the promotional pictures that the Kaitian N70Z/N79Z uses the Zhaoxin KX6640MA, and the General KX6640MA is a quad-core processor with a maximum frequency of 26GHz, a notebook with built-in 16GB memory and a 512GB NVMe solid state drive , built-in 14-inch 22K100% sRGB color gamut eye protection screen.
An upcoming Lenovo notebook belongs to the N70Z and N79Z notebook series. The Kaitian series of products all use chips designed by domestic semiconductor manufacturers, and the most commonly used ones are Hefei Zhaoxin series processors.
Although Lenovo has also launched many products before, including desktop computers and notebook computers, most of them are positioned in the low-end, and they are aimed at the government and enterprise market. Domestic chips are rarely seen, ranging from desktop computers to notebook computers.
A rare domestic chip notebook computer for the consumer market has naturally attracted the attention of many netizens. Many netizens are discussing whether this product is worth buying? There are also some netizens who are curious about the current development of domestic chips, so let Xiaolei analyze this special laptop for everyone.
Is Zhaoxin KX6640MA capable?
As a domestic manufacturer of processor design and production, B02B-PASK Zhaoxin is considered to be the first echelon of current PC processors, mainly engaged in the development and design of processors of the x86 architecture, and the authorization of the x86 architecture comes from VIA. Friends who know a little bit may ask: AMD and Intel have not adopted the x86 architecture? Is this also self-study?
In fact, the x86 architecture is monopolized by AMD and Intel, and Intel also wanted to take back all x86 architecture licenses during this time, but after a lengthy appeal and lawsuit, VIA finally obtained its x86 architecture license, in AMD and Outside of Intel, only three companies have access to the x86 architecture, and it is the third-largest developer of x86 chips, behind AMD and Intel.
On this laptop, it can be seen from the promotional pictures that the Kaitian N70Z/N79Z uses the Zhaoxin KX6640MA, and the General KX6640MA is a quad-core processor with a maximum frequency of 2.6GHz, a notebook with built-in 16GB memory and a 512GB NVMe solid state. Hard disk, built-in 14-inch 2.2K100% sRGB color gamut eye protection screen.
Although the appearance is somewhat similar to the Yoga14 series, the fingerprint unlocking method of the Yoga14 series is not placed under the keyboard, and there may be some mold changes. However, from the appearance design to the ultra-narrow frame, it is currently on the same level as the mainstream mid-to-high-end business models.
In addition to the hardware configuration, Lenovo also listed sales highlights in the upper right corner of the poster, such as only 1.29kg and 14.6mm thick. There are still 14 seconds left to boot, 6 hours of battery life and other selling points, netizens think that there is no advantage (considering the optimized power consumption of domestic chips, system optimization and other issues) In fact, it is already very good). In addition, there are some functions such as fingerprints certified by the Ministry of Public Security of China, dual OS one-key recovery, BIOS-level USB security protection and other functions, which are basically the first choice for business machines.
In terms of configuration, in terms of appearance, at least as a business notebook computer, Kaitian N70Z/N79Z can meet the needs of ordinary users. However, the focus of netizens is mainly on the processor, namely the Zhaoxin KX6640MA. As a quad-core processor, the 2.6GHz frequency has no advantage compared with the current mainstream processors.
However, considering that this is a domestic processor, it is difficult to reach the mobile terminal of 2.6GHz. According to the actual measurement data collected by Xiaolei, Zhaoxin KX6640MA is similar to the mobile ultra-low voltage processor m5-6Y54 launched by Intel in Q3 2015.
The single-core performance of integer operations is about 70% of the 6Y54, and the performance of the multi-core computing core is increased by about 120% of the 6Y54. The floating-point performance is about 50% for single core and about 85% for multi-core (also compared to 6Y54). Although floating-point performance is largely affected by processor architecture, floating-point performance is still largely affected.
However, according to the data provided by Zhaoxin, the target on the Zhaoxin KX6640MA is Intel's i3-5010T, but Xiaolei did not find the data about the i3-5010T on Intel's official website, but Xiaolei did not find any information about the i3-5010T here. 5010T data. In practice, the T series is quite different from the U-shaped processor series. The T series is an ultra-low voltage processor, which is mainly aimed at 2-in-1 thin and light notebooks, tablet computers, and other products with large battery capacity and cooling structure constraints.
However, in general, whether it is i3-5010U or i3-5010T, both are Core series launched in 2015 like m5-6Y54, and Zhaoxin has only been established for 8 years, and the overall progress has been quite good. In terms of performance, there is absolutely no problem in meeting users' office needs, but in the face of such requirements as PS, it may be somewhat powerless.
Is Kaitian N70Z/N79Z worth buying?
Although the price of Kaitian N70Z/N79Z has not been announced, the official did not make more publicity for Kaitian N70Z/N79Z, but whether Kaitian N70Z/N79Z is worth buying, for those friends who have a basic understanding of notebook performance, they should has its own answer.
Although this sentence is a bit ugly, Xiaolei's personal point of view is that unless you really want to support domestic chips, Kaitian N70Z/N79Z is not worth buying by ordinary users. First, in terms of performance, Kaitian N70Z/N79Z are not as good as low-end entry-level laptops priced at 2,000 to 3,000 yuan. Although they can meet office needs, you can definitely buy better performance at the same price. model.
Second, the battery life cannot meet the needs of business users. The 6-hour battery life is not outstanding in current business notebooks, and it can even be said to be relatively backward, partly due to factors such as production technology and battery management.
As far as products are concerned, the main users of notebook computers with domestic processors are government and enterprise departments. For example, government departments have begun to widely use desktop and notebook computers using domestic chips in recent years, while many domestic PC manufacturers such as Lenovo have them. Related products are connected with government procurement departments.
For government departments, the security brought by independent intellectual property rights is essentially the improvement of performance. For the daily work that government departments need to solve, the performance of Kaitian N70Z/N79Z is sufficient, compared with previous generations of products. more significant improvement.
At present, although domestic chip development needs support, it does not need everyone's brainless support. Otherwise, some people may start to hack domestic chips because of love and hatred due to use experience and other reasons, but they cannot rely solely on brain support.
Moreover, at present, domestic chip development mainly relies on government funding and government procurement support. For related chip companies, a small amount of personal purchases will not help the entire research and development progress. But it can make melon eaters who don't know the truth follow Heizi to laugh together and complain that domestic chips are cheating, which in turn leads to a decline in the reputation of domestic chips.
From an objective point of view, the current domestic chips are indeed not worthy of consumers to taste the taste of ordinary consumers. Let us give domestic chips a little more time, and I believe that products worthy of our consideration will be launched in the future. In fact, the above words are all very emotional after Xiaolei read the relevant article. In the reply, many people think that this product is designed to deceive users, so they think this product is to deceive users.
In fact, whether it is Zhaoxin or Loongson, their current R&D expenses are only 10% of Intel's. Under such circumstances, can it be easy to catch up with competitors who have been leading in related fields for decades? Moreover, the current processor performance gap between Loongson and Zhaoxin has narrowed to 10 years, which is worthy of affirmation and encouragement for any aspect.
