Acer Veriton S2660g vs. Dell OptiPlex 5090 SFF
Comparison and Differences
Differences between Acer Veriton S2660g and Dell OptiPlex 5090 SFF
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 5090 SFF which was released in 2021. The Acer Veriton S2660g is older and entered production in 2019.
If you are looking for the smaller form factor the Dell OptiPlex 5090 SFF is the right one for you. It is smaller than the Acer Veriton S2660g 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 5090 SFF as it is running a newer generation CPU. This is not to say that Acer Veriton S2660g is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Dell OptiPlex 5090 SFF has 4 RAM slots while the Acer Veriton S2660g 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 5090 SFF is using the faster 3200 MT/s RAM. The Acer Veriton S2660g is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 5090 SFF as it has the ability to run 128 GB of RAM. The Acer Veriton S2660g 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 5090 SFF has 10 USB ports. The Acer Veriton S2660g 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. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the Acer Veriton S2660g as it has 2 USB3.1 ports (the Dell OptiPlex 5090 SFF has 1).
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 5090 SFF comes with 2 ports, while the Acer Veriton S2660g has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 5090 SFF is the better choice.
The Acer Veriton S2660g comes with an HDMI port, while the Dell OptiPlex 5090 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 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.
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.
