Differences between Acer Veriton S6620g and Dell OptiPlex SFF Plus 7020 2024

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex SFF Plus 7020 2024 which was released in 2024. The Acer Veriton S6620g is older and entered production in 2013.

If you are looking for the smaller form factor the Dell OptiPlex SFF Plus 7020 2024 is the right one for you. It is smaller than the Acer Veriton S6620g 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 Dell OptiPlex SFF Plus 7020 2024 as it is running a newer generation CPU. This is not to say that Acer Veriton S6620g is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (4 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 Dell OptiPlex SFF Plus 7020 2024 is using the faster 4400 MT/s RAM. The Acer Veriton S6620g 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 Dell OptiPlex SFF Plus 7020 2024 as it has the ability to run 128 GB of RAM. The Acer Veriton S6620g 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 Dell OptiPlex SFF Plus 7020 2024 has 10 USB ports. The Acer Veriton S6620g 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. What is nice about the Dell OptiPlex SFF Plus 7020 2024, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Acer Veriton S6620g 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.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex SFF Plus 7020 2024 comes with 3 ports, while the Acer Veriton S6620g has only 1. If you are planning to use multiple monitors, the Dell OptiPlex SFF Plus 7020 2024 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 Acer Veriton S6620g is better equipped as it comes with 6 SATA slot(s), while the Dell OptiPlex SFF Plus 7020 2024 has 3 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 Dell OptiPlex SFF Plus 7020 2024. Sadly, the Acer Veriton S6620g 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 Dell OptiPlex SFF Plus 7020 2024 comes with a decent 300 Watt PSU, but the Acer Veriton S6620g has a more powerful one rated at 500 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.
