Acer Veriton X4620g vs. Fujitsu Esprimo E920
Comparison and Differences
Differences between Acer Veriton X4620g and Fujitsu Esprimo E920
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo E920 which was released in 2014. The Acer Veriton X4620g is older and entered production in 2013.
Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.
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 E920 as it is running a newer generation CPU. This is not to say that Acer Veriton X4620g is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Fujitsu Esprimo E920 has 4 RAM slots while the Acer Veriton X4620g 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 E920 is using the faster 1600 MT/s RAM. The Acer Veriton X4620g is slower by supporting RAM speeds of up to 1333 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Fujitsu Esprimo E920 as it has the ability to run 32 GB of RAM. The Acer Veriton X4620g can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Fujitsu Esprimo E920 has 12 USB ports. The Acer Veriton X4620g is inferior in this regard and packs 8 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Acer Veriton X4620g comes with 2 ports, while the Fujitsu Esprimo E920 has only 1. If you are planning to use multiple monitors, the Acer Veriton X4620g is the better choice.
None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.
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 E920 is better equipped as it comes with 6 SATA slot(s), while the Acer Veriton X4620g has 4 slot(s).
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Acer Veriton X4620g, nor the Fujitsu Esprimo E920 has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.
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 Acer Veriton X4620g comes with a decent 220 Watt PSU, but the Fujitsu Esprimo E920 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.
