Fujitsu Esprimo G5010 vs. Fujitsu Esprimo P520
Comparison and Differences
Differences between Fujitsu Esprimo G5010 and Fujitsu Esprimo P520
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo G5010 which was released in 2020. The Fujitsu Esprimo P520 is older and entered production in 2014.
If you are looking for the smaller form factor the Fujitsu Esprimo G5010 is the right one for you. It is smaller than the Fujitsu Esprimo P520 and will fit more easily under your desk.
Processor
Usually the newer the generation of the CPU, the better the performance and efficiency is. If your budget allows it, you should go with the Fujitsu Esprimo G5010 as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo P520 is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Fujitsu Esprimo P520 has 4 RAM slots while the Fujitsu Esprimo G5010 has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.
The Fujitsu Esprimo G5010 is using the faster 2933 MT/s RAM. The Fujitsu Esprimo P520 is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Fujitsu Esprimo G5010 as it has the ability to run 64 GB of RAM. The Fujitsu Esprimo P520 can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Fujitsu Esprimo P520 has 8 USB ports. The Fujitsu Esprimo G5010 is inferior in this regard and packs 7 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Fujitsu Esprimo G5010, is that it has 1 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Fujitsu Esprimo P520 has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.
The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.
The Fujitsu Esprimo G5010 comes with an HDMI port, while the Fujitsu Esprimo P520 does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).
SATA ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. More SATA slots will allow you to have more drives running at the same time. In this regard the Fujitsu Esprimo P520 is better equipped as it comes with 4 SATA slot(s), while the Fujitsu Esprimo G5010 has 1 slot(s).
If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the Fujitsu Esprimo G5010. Sadly, the Fujitsu Esprimo P520 has no such slot, and you will be forced to use the SATA interface instead.
Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!
Power Supply
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Fujitsu Esprimo G5010 comes with a decent 65 Watt PSU, but the Fujitsu Esprimo P520 has a more powerful one rated at 280 Watts. Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
