Differences between Acer Veriton M6640g and Dell OptiPlex SFF 7020 2024

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex SFF 7020 2024 which was released in 2024. The Acer Veriton M6640g is older and entered production in 2016.

If you are looking for the smaller form factor the Dell OptiPlex SFF 7020 2024 is the right one for you. It is smaller than the Acer Veriton M6640g 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 7020 2024 as it is running a newer generation CPU. This is not to say that Acer Veriton M6640g is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Acer Veriton M6640g has 4 RAM slots while the Dell OptiPlex SFF 7020 2024 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 Dell OptiPlex SFF 7020 2024 is using the faster 5600 MT/s RAM. The Acer Veriton M6640g is slower by supporting RAM speeds of up to 2133 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex SFF 7020 2024 as it has the ability to run 64 GB of RAM. The Acer Veriton M6640g 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 7020 2024 has 8 USB ports. The Acer Veriton M6640g is inferior in this regard and packs 0 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 M6640g comes with 2 ports, while the Dell OptiPlex SFF 7020 2024 has only 1. If you are planning to use multiple monitors, the Acer Veriton M6640g is the better choice.

The Dell OptiPlex SFF 7020 2024 comes with an HDMI port, while the Acer Veriton M6640g 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 Acer Veriton M6640g is better equipped as it comes with 5 SATA slot(s), while the Dell OptiPlex SFF 7020 2024 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

Looking at the Power Supply Unit (PSU) of the two models we don't see any differences. For either of them you get a maximum power of 300 Watts. However be careful, many models have more than one power supply option. When buying your computer, it is a good idea to get a version with the most powerful PSU. This will potentially allow you to upgrade to a more powerful GPU for example.
