We all know that although today’s smart terminals are very popular, and the big guys in the Internet circle have concluded that the Internet revolution has arrived, that is, the traditional PC network is slowly declining, and will be replaced by mobile Mobile Internet brought by terminals. However, the editor believes that there is still a long way to go before mobile Internet can completely replace traditional PCs. It is undeniable that the PC side will still be a major part of the Internet now and even for many years to come. Therefore, computers are still very important office and entertainment products. So today we will take a look at the evaluation of the Lenovo Rising Sun n220, a notebook from the domestic giant Lenovo. ​

Battery life and heat dissipation test

According to the screenshot of BatteryMark, it can be clearly seen that the battery life of the machine is 3 hours and 44 minutes. . For a 12-inch notebook using the Centrino 4 platform, this kind of battery life is already quite good. The excellent battery life is due to HP's use of various energy-saving measures, and the long battery life allows users to avoid the embarrassment of running out of battery power in applications with mobile needs.

Heat dissipation is often a problem that needs attention, especially for business laptops that need to be used for a long time. This problem is also more obvious. A well-designed notebook product can evenly distribute excess heat throughout the machine so that the temperature of each part will not be too high. The well-designed air duct can also quickly take excess temperature away from the notebook. The editor's test method is: run the notebook PCMark05 for 30 minutes and then use an infrared thermometer to conduct a temperature test.

From the temperature diagram above, we can see that the highest temperature of the keyboard operating surface appears in the middle of the keyboard area of ​​the notebook, which is 35°C. The temperatures of the left and right palm rests, which have been touched for a longer time, remain at around 33°C and 32°C, but the temperature of the mouse touchpad is slightly higher at 35°C. Generally speaking, the temperature of the keyboard operating surface of this notebook is slightly high, but it will not cause inconvenience to the user.

The highest temperature at the bottom of the machine occurred in the hard drive, reaching a temperature of 42°C. On the contrary, the temperature near the laptop's air outlet is not very high, at 36°C. Relatively speaking, the temperature control at the bottom of the body is still within the allowable range. But this temperatureIt will cause some discomfort to users who use the laptop on their lap for a long time. The temperature of the air outlet on the left side of the machine is 41°C, and the built-in radiator can still discharge excess heat out of the machine when running at full speed.

Hard drive performance and business performance test

The Lenovo N220 notebook uses a Seagate brand hard drive. As for hard drives, many consumers only pay attention to their capacity. In fact, as one of the few electromechanical products in the system, they often become the bottleneck of the entire system. If the hard disk performance in the current system is high, it can effectively improve system performance and reduce system waiting time.

HDTach is a software that can objectively evaluate hard drives and provide intuitive sequential reading curves at the end of the test. Through the screenshots of the software, we can see that the Lenovo N220 notebook uses a Seagate 5400rpm 120GB SerialATA hard drive numbered ST9120822AS. The hard drive has a high burst transfer rate, reaching a speed of 128MB/second; its average read speed is 35.2MB/second. Judging from the sequential read curve, this hard drive basically maintains a balanced decline curve except for four fluctuations during the decline process. Based on the results obtained from the previous test, we can know that this hard drive will significantly reduce system latency and bring faster file processing speed to users.

For business applications, the editor used two projects, File Systems and Memory Bandwidth, in SiSoftware2007 for testing. The two test sub-items test the notebook system based on the hard disk and memory respectively, and finally quantify it into a histogram and compare it with other data in the database.

As can be seen from the above two screenshots, the N220, which uses the Centrino 4 platform, has performed well in both FileSystems and Memory Bandwidth. Although there is still a certain gap with the desktop platform, the difference data has been gradually narrowed compared with the previous platform. In particular, for such a notebook whose main goal is business performance, this kind of performance is already quite excellent. ​

Test of the display chip and processor part

Since it uses the GM965 Northbridge chipset, the notebook uses its built-in GMA X3100 integrated display chip in the display part. Through the previous tests, we found that this chip is already comparable to the previous generation of independent display chips, so the editor selected three versions of 3DMark03, 05, and 06 test software to test it.

It can be seen from the final scores of 1579, 848 and 564 in 3DMark03, 05 and 06 that compared to the previous generation of independent display chips, the Lenovo N220 notebook using the GMA X3100 integrated display chip has better 3D display performance It does show an advantage, but this advantage is not overwhelming. Therefore, the N220 notebook using this integrated display chip will still be slightly weak when facing today's large-scale 3D games. However, for games like "World of Warcraft", this independent display chip can still run with ease. .

But we also have to see that notebooks with integrated display chips will perform better in terms of cost control, battery life and multi-display functions.

Lenovo N220 notebook is equipped with Intel Core2 Duo T7100 processor. This processor uses the Merom core, has a main frequency of 1.8GHz, a front-side bus frequency of 800MHz and a 2MB level 2 cache. The processor has always been the most important component of the system, and it has always been one of the standards by which people measure the grade of a notebook.

For this top processor in the Centrino 4 platform, the editor used two commonly used software, Super PI and CINEBench, to perform hard calculations on it. test.

Super PI passes on piThis group of infinite non-recurring decimals after the decimal point performs millions of digit operations to test the scientific computing power of the processor. According to the screenshot above, we can see that the Lenovo N220 notebook using the T7100 processor completed the decimal calculation of 1.04 million digits in only 31 seconds. The results of Super PI will be affected by some other factors, so the editor used CINEBench software for subsequent testing.

CINEBench objectively evaluates the computing performance of the processor by rendering an image. According to the test, Lenovo N220 achieved final scores of 310 and 551 in single-core computing and multi-core computing respectively. And judging from the rendering time, the notebook only took 40 seconds to render the image. Consistent with the conclusions drawn from previous tests, the processor is capable of delivering extremely high performance in a variety of applications.

The above is a simple evaluation of this business-like notebook. The first thing we need to know is that the PC side is the cornerstone of Lenovo. After the acquisition of IBM, Lenovo's strength cannot be underestimated. In addition, Lenovo's other businesses such as mobile terminals have performed very poorly in the past two years, which also highlights that Lenovo's computers are very powerful. This product is not a flagship phone, so the relevant configuration can only be said to be sufficient, so friends who usually have higher business requirements should check it out.
