Dell OptiPlex 7070M vs. Lenovo ThinkCentre M72e Tiny
Comparison and Differences
Differences between Dell OptiPlex 7070M and Lenovo ThinkCentre M72e Tiny
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 7070M which was released in 2019. The Lenovo ThinkCentre M72e Tiny is older and entered production in 2012.
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 7070M as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M72e Tiny is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
Both models have have equal amount of ram slots (2 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.
The Dell OptiPlex 7070M is using the faster 2666 MT/s RAM. The Lenovo ThinkCentre M72e Tiny is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 7070M as it has the ability to run 32 GB of RAM. The Lenovo ThinkCentre M72e Tiny can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Dell OptiPlex 7070M has 6 USB ports. The Lenovo ThinkCentre M72e Tiny is inferior in this regard and packs 5 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Dell OptiPlex 7070M, is that it has 1 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Lenovo ThinkCentre M72e Tiny 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.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 7070M comes with 2 ports, while the Lenovo ThinkCentre M72e Tiny has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 7070M is the better choice.
None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.
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 1 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
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 7070M. Sadly, the Lenovo ThinkCentre M72e Tiny 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
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Lenovo ThinkCentre M72e Tiny comes with a decent 65 Watt PSU, but the Dell OptiPlex 7070M has a more powerful one rated at 130 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.
