We are already familiar with the Lenovo Qitian series, a commercial PC brand for the industry, corporate, government and education markets with a deep history. Because of this, when we get the Lenovo Qitian M5800-N000 with AMD APU platform, it will be full of curiosity: What changes will AMD APU bring to commercial PCs?
This Qitian M5800-N000 adopts AMD A8-5500B APU+AMD Radeon HD7450 discrete graphics card configuration, this configuration is special, because the performance of the latter is actually not enough to provide too much APU with a strong display core. Add points. We suspect that the combination of this configuration is more to cater to the procurement needs of dual-graphics configurations for some industry users. What we are more concerned about is how the A8-5500B commercial APU series with the "B" suffix can bring changes to the entire commercial PC market.
Overall picture
Legend 1: The side panel of the fuselage can be opened. Note that this cooling window is actually located on the hard disk.
Note 2: The front panel provides two USB ports and an audio interface for easy connection to mobile storage devices. In fact, the appearance of the Lenovo Qitian series is very mature, so there has not been much change over the years.

Basic parameters
AMD APU A8-5500B (3.2GHz, quad core)
4GB DDR3 1600
500GB SATA HDD
AMD Radeon HD 7450 1GB
SuperMulTI-DVD
Windows 8
Advantages and disadvantages
Advantages: AMD A8-5500B APU performance balanced, providing a rich interface
Disadvantages: the graphics card configuration is slightly lower
In fact, the A8-5500B has already been released, but the frequency of appearance in the commercial PC market is not high. After all, it is not easy to kill a bloody road in Intel's own commercial market. It belongs to Trinity APU series, has 4 processor cores and 4MB L2 cache, is manufactured in 32nm process, and has TDP power consumption of 65W, which integrates Radeon HD 7560D display core. In terms of specifications, it is basically the same as the A8-5500 for the consumer market. In order to understand the performance of this commercial APU, after completing the basic performance test of the Qitian M5800, we removed the discrete graphics card and tested it with the APU fusion display core model.
In terms of test scores, the PCMark 8 Work project scored more than 3,700 points, indicating that its performance is sufficient to meet the needs of major work applications. At the same time, it scored more than 3,000 points in the new 3DMark Cloud Gate, which is much higher than the Intel HD Graphics 4000 series of core graphics. Maybe users have no problem playing 3D games in their spare time. In the CineBench R15, the A8-5500B outperformed the Intel Core i5-3317U, reaching 251cb/18.97fps.
Figure: In the case of the AMD A8-5500B APU alone, the 3DMark Cloud Gate score still reached 3,000 points or more.
Figure: PCMark Work project test scores reached more than 4,000, and from its detailed results, the performance is fairly balanced.
Edit review
From the test results, AMD A8-5500B APU has a relatively balanced computing and graphics rendering capabilities, both for document editing needs, but also to provide better performance support for Photoshop image processing. Correspondingly, the Lenovo Qitian M5800-N000 with this platform also has relatively balanced performance and versatile performance, which is more suitable for more complex office positions and environments, and becomes a more flexible choice.
