Differences between Acer Veriton N4660g and Dell OptiPlex 3090 SFF

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3090 SFF which was released in 2021. The Acer Veriton N4660g is older and entered production in 2018.

If you are looking for the smaller form factor the Acer Veriton N4660g is the right one for you. It is smaller than the Dell OptiPlex 3090 SFF 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 3090 SFF as it is running a newer generation CPU. This is not to say that Acer Veriton N4660g 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.

None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 2666. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 3090 SFF as it has the ability to run 64 GB of RAM. The Acer Veriton N4660g 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 3090 SFF has 8 USB ports. The Acer Veriton N4660g is inferior in this regard and packs 7 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Acer Veriton N4660g, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 3090 SFF 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 3090 SFF comes with 2 ports, while the Acer Veriton N4660g has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 3090 SFF is the better choice.

The Acer Veriton N4660g comes with an HDMI port, while the Dell OptiPlex 3090 SFF 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 Dell OptiPlex 3090 SFF is better equipped as it comes with 2 SATA slot(s), while the Acer Veriton N4660g has 1 slot(s).

An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the Acer Veriton N4660g has 1 M.2 slots while the Dell OptiPlex 3090 SFF comes with just 1.

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 N4660g comes with a decent 135 Watt PSU, but the Dell OptiPlex 3090 SFF has a more powerful one rated at 200 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.
