Considering the specs of this CPU, the Lenovo P15s should be able to handle most tasks thrown at it. As a matter of fact, the laptop shouldn’t have any issue performing heavy-duty tasks, like video editing, with this processor.
To give you a better insight into the laptop’s performance with this CPU, I will highlight its result on the Cinebench R15 test. Before that, I would like to explain what this test is all about and how it works.
To start with, the Cinebench R15 test is a benchmark test that gauges the overall processing performance of a computer. It does this by putting the cores of the computer’s processor through intensive workloads.
Due to this, the test involves two separate tests – the single-core performance test and the multi-core performance test. The single-core test measures the computer’s processing power when one of its CPU cores is in use.
However, the multi-core test evaluates the processing ability of the computer when all the CPU cores are in use. Notably, high scores on the Cinebench R15 tests represent good performance.

Meanwhile, on the multi-core test, the laptop recorded a score of 379 points.
Sadly, the laptop was outperformed by the Dell Precision 5520, which uses an Intel Xeon E3-1505M v6 processor. Specifically, this Dell laptop scored 170 points on the single-core test and 654 points on the multi-core test.
All in all, I will rate the Lenovo P51s an eight out of ten in this section.
Lenovo P51s: Memory (RAM) Performance
The Lenovo P51s comes with a standard 8 GB DDR4 2133 MHz RAM. Also, it has two memory slots and supports a maximum memory of 32 GB.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsThus, you can upgrade the laptop’s memory up to 32 GB. However, that might not be necessary.
This is because the standard 8 GB RAM is sufficient for the laptop to handle most computing tasks smoothly. In actual fact, the Lenovo P51s should be able to multitask effectively with the standard 8 GB RAM.
Speaking of which, this laptop with 8 GB RAM can run about 15 Chrome tabs simultaneously while streaming a YouTube video without lagging. In fact, switching between the Chrome tabs and the YouTube video won’t cause the laptop to slow down.
With that being said, I will now share the laptop’s PCMark 8 test result to further assess its performance with 8 GB RAM. Briefly, PCMark 8 measures a device’s overall performance by simulating various productivity tasks.
Additionally, a high score on the test signifies good performance. So, according to the test results, the Lenovo P51s scored 3232 points.
Although this score is impressive, it isn’t high enough to outperform the 3262 points scored by the HP ZBook Studio G3.
Nonetheless, I believe the Lenovo P51s deserves an eight out of ten rating in this memory review section.
Lenovo P51s: Storage Options and Performance
Regarding storage, the Lenovo P51s offers multiple storage options – 5400 RPM SATA HDD and M.2 NVMe PCIe SSD. Impressively, with either storage option, the laptop supports a maximum storage capacity of 1 TB.

In addition to that, the Lenovo P51s features an SD card reader for storage expansion. That said, I strongly suggest you purchase this laptop with the M.2 NVMe PCIe SSD storage option.
This is because SSDs are very fast and offer rapid boot time. Gladly, this review focuses on the Lenovo P51s with 256 GB M.2 NVMe PCIe SSD.
To determine the storage performance of the laptop, let us discuss its CrystalDiskMark test result. CrystalDiskMark evaluates a computer’s storage performance by measuring the read and write speed of its storage drive.
For your information, read speed refers to how fast it takes a storage drive to open files. On the other hand, write speed is how fast it takes the storage drive to save a file.

In that regard, the Lenovo P51s with 256 GB M.2 NVMe PCIe SSD delivered a read speed of 1189 MB/s and a write speed of 1138 MB/s.
In comparison, the HP ZBook Studio G3, which also uses SSD, recorded a faster read and write speed. Specifically, it recorded a read speed of 1578 MB/s and a write speed of 1557 MB/s on the CrystalDiskMark test.
In conclusion, the Lenovo P51s offers multiple storage options with sufficient storage space and an SD card reader. However, the laptop with the SSD storage option was outperformed by one of its major rivals on a storage benchmark test.
As a result, I will rate the Lenovo P51s an eight out of ten.
