Since 2013, Lenovo has become the world's largest PC manufacturer, occupying the first place in the global market share for a long time, and also became the largest computer brand in Japan through the acquisition of Fujitsu in 2017.
 
The status of desktops is declining, and Lenovo's attention to desktops is not as good as the notebook product line, but even so, Lenovo still has an advantage in this field, and the "2017 China Digital Industry Research Report" released by the operator world network shows that Lenovo's desktop sales are still at the top of the list.
 
Desktops face the double attack of DIY assembly machines and notebooks with increasingly powerful performance, which is the most affected in the market, which can also be seen from the number of Lenovo's desktops, different from complicated notebooks, Lenovo's desktop product line is quite simple, only Ideacentre series and ThinkCentre series, respectively, for different groups of people, from the price point of view, ThinkCentre's overall positioning is higher than that of Ideacentre series.
 
The original positioning of the Ideacentre series is home entertainment, similar to the Ideapad series of notebooks, the appearance is mainly low-key black and gray, and the customers are students, customers in the political and educational industries, small and medium-sized enterprise office workers and other people with low requirements, and the ThinkCentre series is the same three-year warranty, from high to low, it can be subdivided into Ruiying 620 series and Tianyi 510 series, mainly in the appearance and size of the chassis.
 
ThinkCentre series is IBM's original desktop series,Similar to the positioning of Thinkpad in notebooks,It has not changed its positioning after being acquired by Lenovo,It has been a pure commercial series,Tower case design,It has strong scalability,But in recent years, it has also begun to face non-commercial user groups,Launched a high-performance game model with Y suffix,Named after E number,The larger the number, the more high-end,At the same time, there are various suffixes,S suffix means small chassis, The Y suffix indicates a game-specific model.
 
Among Lenovo's home/commercial desktops, the Tianyi 510 Pro Ryzen processor version should be Lenovo's most cost-effective model, with Ryzen 3 and Ryzen 5 two products, the prices are 2899 yuan and 3799 yuan respectively, AMD Ryzen 3 is similar to i3 8100 in performance, and Ryzen 5 is slightly better than i5 8400, and the powerful Vega core graphics performance is more than 2 times that of Intel core graphics card, similar to GT 1030 independent graphics card, Compared with the Intel platform model, it has a price advantage of nearly 1,000 yuan, and the performance is stronger but the price is lower, so it is undoubtedly more worth buying.
 
If space is limited, you can consider the Tianyi 510S, although it has little advantages in all aspects compared to the Tianyi 510 Pro, but it also has characteristics that the 510 does not have. 510S uses a mini chassis, the volume is only about half of the Tianyi 510 Pro, but the cost performance is not as good as the Tianyi 510 Pro Ryzen processor version, only suitable for users who are very tight on space, in actual use, 4G memory is more tight, so Tianyi 510S (i3-7100 8G is more recommended).
 
Users who have performance requirements can also choose ThinkCentre E75Y(i5-7400 8G),ThinkCentre has always belonged to the business series,E75Y can be said to be a test product to enter the game PC market,The chassis volume is between Tianyi 510 Pro and Tianyi 510S,i5-7400 GTX 1050Ti independent graphics card can meet most of the game needs,While retaining the back serial port,Let it have some characteristics of commercial PC, Therefore, it can be regarded as a commercial, game dual-purpose product, but the price of 6699 yuan is high, and there is no advantage over other brands of products of the same level.
