Dell OptiPlex 3050 MT vs. Lenovo ThinkCentre M82 Small
Comparison and Differences
Differences between Dell OptiPlex 3050 MT and Lenovo ThinkCentre M82 Small
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3050 MT which was released in 2017. The Lenovo ThinkCentre M82 Small is older and entered production in 2012.
If you are looking for the smaller form factor the Lenovo ThinkCentre M82 Small is the right one for you. It is smaller than the Dell OptiPlex 3050 MT 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 3050 MT as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M82 Small is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Lenovo ThinkCentre M82 Small has 4 RAM slots while the Dell OptiPlex 3050 MT 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 3050 MT is using the faster 2400 MT/s RAM. The Lenovo ThinkCentre M82 Small 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.
Ports
Both models have the same amount of USB ports for total count of 8. If this is not enough, using a USB hub is always a viable option. 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.
The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.
The Dell OptiPlex 3050 MT comes with an HDMI port, while the Lenovo ThinkCentre M82 Small 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 M82 Small is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 3050 MT has 3 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 3050 MT. Sadly, the Lenovo ThinkCentre M82 Small has no such slot, and you will be forced to use the SATA interface instead.
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 240 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.
