High input-output ratio is the correct solution Lenovo Yangzhou M4000q evaluation

commercial Desktop As we all know, efficiency and stability are at the core of the enterprise procurement. But in the case of limited budget, the difficulty is to "spend money on the cutting edge". The concept of "input-output ratio" has to be mentioned here. The input of purchasing a commercial desktop computer is divided by the output it can bring. The higher the ratio, the more suitable the purchased product is. So the purchase is not the most expensive, but the most suitable. Equipped with the 12th generation Core and PCIe 4.0 solid state disk Lenovo Yangtian M4000q , perhaps a "suitable" commercial desktop.

Yangtian has always been positioned as a pragmatic business, and its brand Slogan is "striving for the future". It provides stable and reliable product strength, but also has a very good cost performance ratio. As an old commercial brand for more than 20 years, it has a very accurate grasp of business needs. This is quite obvious in Lenovo Yangzhou M4000q.

The hardware specifications of the Lenovo Yangtian M4000q on my hand are: i5-12400, 16GBDDR4 3200, 256GBPCIe 4.0 SSD+1TB HDD, Wi Fi 6 support, 260W power supply, 7.4L volume, and 1 million hour stability test.

1、 The practical application performance of the 12th generation Core is excellent

Lenovo Yangzhou M4000q is equipped with Intel's 12th generation Core i5-12400, which is a 6-core 12 thread processor with Intel 7 technology. The maximum Remax frequency can reach 4.4GHz. For daily office work, the performance of this processor is completely enough. Maybe some friends have questions, why not choose the 13 generation Core just launched?

We return to the work itself. It is believed that most users' work focuses on Office and browser In most cases, the processor's single core performance is more important. In terms of architecture, the i5-12400 is not very different from the latest i5-13400, and the single core performance improvement is not particularly obvious.

This can be seen in the test. I use the application mode of PCMARK10 to test. The test items include Word 、 Excel , PPT and Edge browser, which are closer to the actual working situation. Lenovo Yangtian M4000q scored 6639 points for Word, 25323 points for Excel, 2454 points for PPT and 12266 points for Edge. This score is excellent for an office machine.

For desktop computers equipped with i5-13400, the scores of four items are respectively: Word7225, Excel27488, PPT14495, Edge12205, and the overall performance improvement is only 8%. When it comes to practical experience, people may not feel the gap in their work. It can be said that in terms of office work, the efficiency of the two is relatively close.

Of course, there are still some promotions, which cannot be ignored. However, we also need to consider the cost, that is, the "input" in the input-output ratio. The performance improvement of the 13th generation Core i5-13400 is only a single digit, 8%, but the price increase is as high as 20% (retail price), which is obviously not conducive to improving the input-output ratio. The reason is that the 13th generation Core has just come into the market, with high price and low cost performance. The 12th generation Core is in the stage of price reduction, with cost advantages.

In addition, the 12th generation Core has been widely adopted, and its stability is guaranteed after market verification, which is very important for commercial products.

Therefore, it is still a good choice for enterprises to carry the 12th generation of commercial desktop computers. Back to the i5-12400, in the test of Cinebench R20, its multi-core score was 4729pts and the single core score was 660pts, which belongs to the middle end level of current desktop processors; stay Photoshop In the test, he scored 933 points, which belongs to the upper middle level. From these two achievements, we can see that the i5-12400 is sufficient for daily office, graphic design and other applications.

In terms of continuous performance release, after a 20 minute stress FPU, the i5-12400's frequency stabilized at 3.6GHz, power consumption stabilized at 65W, and the maximum core temperature was only 78 °. The test results show that the i5-12400 has stable performance output, low heating, and no obvious fan noise, which is very suitable for office use.

2、 PCIe 4.0 solid state disk is more efficient

Another highlight of Lenovo Yangtian M4000q is storage. The machine adopts a combination of 256GBPCIe 4.0 solid state disk and 1TB mechanical disk, which can give consideration to both speed and capacity. In particular, the application of PCIe 4.0 solid state disk can improve office efficiency. The PCIe4.0 solid state disk comes from the Armour Xia, which is known as Toshiba. It uses the original particles, and the data security is guaranteed.

from CrystalDiskInfo As can be seen from, the transmission mode of this SSD is PCIe 4.0x4, which is a genuine PCIe 4.0 SSD. At present, the latest and widely used standard of solid state disk is PCIe 4.0. Compared with the previous generation of PCIe 3.0, the theoretical performance of PCIe 4.0 has doubled, which can theoretically save half of the time. Of course, it also depends on the location and actual performance of the specific hard disk.

The measured theoretical speed of this SSD is 3350.6MB/s for continuous reading and 2008.38MB/s for continuous writing. From the results, we can see that this SSD is positioned as a mid tier, and its performance has been comparable to that of high-end PCIe 3.0 SSDs.

Compared with the previous generation of PCIe3.0 solid state disk models, the latter has 2984.52MB/s continuous reading and 1645.81MB/s continuous writing. The Lenovo Yangzhou M4000q with PCIe 4.0 solid state disk is significantly faster and more efficient in data transmission.

More importantly, Lenovo Yangtian M4000q did not increase its price because of the availability of PCIe 4.0 solid state drives, which is quite conscientious and suitable for enterprises to purchase.

In addition to internal data transmission, we often need to copy the data in the mobile hard disk to the computer in our work. In this scenario, the advantages of PCIe 4.0 solid state disk are also obvious. I prepared a test file with a capacity of 17.9GB and copied it to the PCIe 4.0 solid state disk and mechanical disk in turn.

The measured time of PCIe4.0 SSD is 14.86 seconds, and the transmission speed during the process can reach 1.46GB/s; The mechanical hard disk takes 89.65 seconds, and the transmission speed during the process can reach 171MB/s. The difference between the two is six times, and the gap is relatively obvious.

3、 Stable under high strength pressure

In addition to high efficiency, the stability performance of Lenovo Yangtian M4000q is also extremely excellent. It has passed the 1000000 hour stability test, which is rigorous, including EMI, ESD, safety regulations, impact, drop, high and low temperature operation and storage, EELP+, noise, regulation, fall, fall resistance One click recovery , low air pressure and other tests. This means that Lenovo Yangtian M4000q will not challenge the working environment, and can deal with minor accidents in daily work.

In addition, Lenovo Yangtian M4000q has also passed 3C certification, energy-saving certification, ten ring certification, TUV low-noise certification, and the lightning protection report of the whole machine, which is enough to show that the quality is very reliable.

So what's the actual performance? I use AIDA64 The system stability test was carried out. The test items include the processor (StressCPU), memory and hard disk (C disk). The test went further. The test lasted for 20 hours, and the pressure was much higher than normal work. If the test is passed, the stability of daily work will not be a problem.

The measured results are quite good. Lenovo Yangtian M4000q has not only passed the pressure test for 20 consecutive hours, but also the processor frequency has not decreased, and has been maintained at about 4GHz. In other words, Lenovo Yangzhou M4000q not only did not report errors, but also had excellent performance stability. Users can safely hand over heavy and time-consuming work to Lenovo Yangzhou M4000q.

This stability performance is excellent and necessary for a commercial desktop computer.

4、 Experience ceiling of commercial desktop

From the above tests, we can see that Lenovo Yangtian M4000q performs well in both efficiency and stability. In addition to these two points, Lenovo Yangtian M4000q is a very "humanized" product, and its use experience can be regarded as a leader in commercial desktops.

First of all, the body of the Lenovo Yangtian M4000q is very small, only 7.4L, which is much smaller than the traditional commercial desktop.

Moreover, the design of Lenovo Yangtian M4000q is also simple and generous, with a very design sense on the front. The left side is a vertical bar design, giving a sense of stability; The right side is a large area of silver decorative plate, which forms a contrast between the two. In addition, the lower right side has a three-dimensional oblique cutting treatment. The whole front is stable but not dull, which is more eye-catching.

Secondly, Lenovo Yangtian M4000q has a built-in wireless network card, AX201, which supports the Wi Fi 6 protocol. It is convenient for desktop computers to support Wi Fi, which saves the trouble of connecting network cables and makes it easier for desktop cabling. Moreover, the AX201 has a good reputation for its performance. It supports a maximum transmission speed of 2.4Gbps. In addition to the Wi Fi 6 protocol, it can provide a network experience without transmission lines.
