Differences between Dell OptiPlex 3070M and Lenovo ThinkCentre M83 Tower
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3070M which was released in 2019. The Lenovo ThinkCentre M83 Tower is older and entered production in 2013.
If you are looking for the smaller form factor the Dell OptiPlex 3070M is the right one for you. It is smaller than the Lenovo ThinkCentre M83 Tower and will fit more easily under your desk.
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 3070M as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M83 Tower is bad - it can still run some powerful CPUs, albeit being an older generation.
The Lenovo ThinkCentre M83 Tower has 4 RAM slots while the Dell OptiPlex 3070M has only 2 slot(s). Of course this is not something to worry about. Just make sure you take it into consideration when planning how much RAM will your system be using.The Dell OptiPlex 3070M is using the faster 2666 MT/s RAM. The Lenovo ThinkCentre M83 Tower is slower by supporting RAM speeds of up to 1600 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 32 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.
In total the Lenovo ThinkCentre M83 Tower has 8 USB ports. The Dell OptiPlex 3070M 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. 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 Lenovo ThinkCentre M83 Tower comes with 2 ports, while the Dell OptiPlex 3070M has only 1. If you are planning to use multiple monitors, the Lenovo ThinkCentre M83 Tower is the better choice.
The Dell OptiPlex 3070M comes with an HDMI port, while the Lenovo ThinkCentre M83 Tower 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 Lenovo ThinkCentre M83 Tower is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 3070M has 1 slot(s).
If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the Dell OptiPlex 3070M. Sadly, the Lenovo ThinkCentre M83 Tower has no such slot, and you will be forced to use the SATA interface instead.Remark: 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!
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Dell OptiPlex 3070M comes with a decent 65 Watt PSU, but the Lenovo ThinkCentre M83 Tower has a more powerful one rated at 240 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.
