Fujitsu Esprimo G9012 vs. Fujitsu Esprimo P558
Comparison and Differences
Differences between Fujitsu Esprimo G9012 and Fujitsu Esprimo P558
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo G9012 which was released in 2022. The Fujitsu Esprimo P558 is older and entered production in 2018.
If you are looking for the smaller form factor the Fujitsu Esprimo G9012 is the right one for you. It is smaller than the Fujitsu Esprimo P558 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 G9012 as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo P558 is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
Both models have have equal amount of ram slots (2 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.
The Fujitsu Esprimo G9012 is using the faster 3200 MT/s RAM. The Fujitsu Esprimo P558 is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Fujitsu Esprimo G9012 as it has the ability to run 64 GB of RAM. The Fujitsu Esprimo P558 can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.
Ports
Both models have the same amount of USB ports for total count of 8. If this is not enough, using a USB hub is always a viable option. What is nice about the Fujitsu Esprimo G9012, is that it has 5 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Fujitsu Esprimo P558 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 G9012 comes with an HDMI port, while the Fujitsu Esprimo P558 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 P558 is better equipped as it comes with 3 SATA slot(s), while the Fujitsu Esprimo G9012 has 2 slot(s).
When your goal is to have the fastest SSD transfer speeds, an M.2 interface is crucial. Thus, it is good that both models have M.2 SSD slots. Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to invest in SATA drives anymore.
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 G9012 comes with a decent 150 Watt PSU, but the Fujitsu Esprimo P558 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.
