Dell OptiPlex 7050 SFF vs. Lenovo ThinkCentre M93p Small Pro
Comparison and Differences
Differences between Dell OptiPlex 7050 SFF and Lenovo ThinkCentre M93p Small Pro
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 7050 SFF which was released in 2017. The Lenovo ThinkCentre M93p Small Pro is older and entered production in 2013.
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 7050 SFF as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M93p Small Pro is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
Both models have have equal amount of ram slots (4 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 7050 SFF is using the faster 2400 MT/s RAM. The Lenovo ThinkCentre M93p Small Pro 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 7050 SFF as it has the ability to run 64 GB of RAM. The Lenovo ThinkCentre M93p Small Pro 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 7050 SFF has 10 USB ports. The Lenovo ThinkCentre M93p Small Pro is inferior in this regard and packs 8 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.
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 7050 SFF comes with an HDMI port, while the Lenovo ThinkCentre M93p Small Pro 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 M93p Small Pro is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 7050 SFF 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 7050 SFF. Sadly, the Lenovo ThinkCentre M93p Small Pro 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 Dell OptiPlex 7050 SFF comes with a decent 180 Watt PSU, but the Lenovo ThinkCentre M93p Small Pro 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.
