Dell OptiPlex 9010 USFF vs. Lenovo ThinkCentre M73 Small

Differences between Dell OptiPlex 9010 USFF and Lenovo ThinkCentre M73 Small

If you are looking for a more modern desktop, then you should go with the Lenovo ThinkCentre M73 Small which was released in 2013. The Dell OptiPlex 9010 USFF is older and entered production in 2012.

If you are looking for the smaller form factor the Dell OptiPlex 9010 USFF is the right one for you. It is smaller than the Lenovo ThinkCentre M73 Small 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 Lenovo ThinkCentre M73 Small as it is running a newer generation CPU. This is not to say that Dell OptiPlex 9010 USFF 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.

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 1600. In addition, you will be able to install the same amount of RAM in both models, and most probably 16 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 6. 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.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 9010 USFF comes with 2 ports, while the Lenovo ThinkCentre M73 Small has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 9010 USFF 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 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 M73 Small is better equipped as it comes with 3 SATA slot(s), while the Dell OptiPlex 9010 USFF has 2 slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell OptiPlex 9010 USFF, nor the Lenovo ThinkCentre M73 Small has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

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 9010 USFF comes with a decent 200 Watt PSU, but the Lenovo ThinkCentre M73 Small 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.
