Differences between Acer Veriton X2660g and Fujitsu Esprimo E520

If you are looking for a more modern desktop, then you should go with the Acer Veriton X2660g which was released in 2018. The Fujitsu Esprimo E520 is older and entered production in 2014.

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 Acer Veriton X2660g as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo E520 is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Fujitsu Esprimo E520 has 4 RAM slots while the Acer Veriton X2660g 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 Acer Veriton X2660g is using the faster 2666 MT/s RAM. The Fujitsu Esprimo E520 is slower by supporting RAM speeds of up to 1600 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 32 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.

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 Acer Veriton X2660g, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Fujitsu Esprimo E520 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 Acer Veriton X2660g comes with an HDMI port, while the Fujitsu Esprimo E520 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 slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 4 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.

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 Acer Veriton X2660g. Sadly, the Fujitsu Esprimo E520 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 Acer Veriton X2660g comes with a decent 250 Watt PSU, but the Fujitsu Esprimo E520 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.
