Dell OptiPlex 5070 MT vs. Dell Vostro 3470
Comparison and Differences
Differences between Dell OptiPlex 5070 MT and Dell Vostro 3470
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 5070 MT which was released in 2019. The Dell Vostro 3470 is older and entered production in 2018.
If you are looking for the smaller form factor the Dell Vostro 3470 is the right one for you. It is smaller than the Dell OptiPlex 5070 MT and will fit more easily under your desk.
Processor
The two models have the same generation of Intel processors. We think that the 9 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.
Memory
The Dell OptiPlex 5070 MT has 4 RAM slots while the Dell Vostro 3470 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.
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 5070 MT as it has the ability to run 64 GB of RAM. The Dell Vostro 3470 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 5070 MT has 10 USB ports. The Dell Vostro 3470 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 5070 MT, is that it has 1 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell Vostro 3470 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 5070 MT has a DisplayPort. The Dell Vostro 3470 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
The Dell Vostro 3470 comes with an HDMI port, while the Dell OptiPlex 5070 MT 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 5070 MT is better equipped as it comes with 4 SATA slot(s), while the Dell Vostro 3470 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
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 3470 comes with a decent 200 Watt PSU, but the Dell OptiPlex 5070 MT has a more powerful one rated at 260 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.
