Dell OptiPlex 7090 MT vs. Dell Vostro 3671
Comparison and Differences
Differences between Dell OptiPlex 7090 MT and Dell Vostro 3671
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 7090 MT which was released in 2021. The Dell Vostro 3671 is older and entered production in 2019.
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 Dell OptiPlex 7090 MT as it is running a newer generation CPU. This is not to say that Dell Vostro 3671 is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Dell OptiPlex 7090 MT has 4 RAM slots while the Dell Vostro 3671 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 7090 MT is using the faster 3200 MT/s RAM. The Dell Vostro 3671 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 7090 MT as it has the ability to run 128 GB of RAM. The Dell Vostro 3671 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 7090 MT has 9 USB ports. The Dell Vostro 3671 is inferior in this regard and packs 6 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Dell OptiPlex 7090 MT, is that it has 3 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell Vostro 3671 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.
Unfortunately, only the Dell OptiPlex 7090 MT has a DisplayPort. The Dell Vostro 3671 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
The HDMI video interface is broadly used and the majority of the external displays support it. Thus, it is nice to see that both models have this video interface. If you are going to use multiple monitors go with the Dell OptiPlex 7090 MT which has 2 ports. The Dell Vostro 3671 has only 1 ports.
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.
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 Dell OptiPlex 7090 MT has 1 M.2 slots while the Dell Vostro 3671 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 Dell Vostro 3671 comes with a decent 290 Watt PSU, but the Dell OptiPlex 7090 MT 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.
