Differences between HP ProDesk 400 G1 SFF and Lenovo ThinkCentre M93 Small Pro

Both computers, the HP ProDesk 400 G1 SFF and the Lenovo ThinkCentre M93 Small Pro, were released during the same year - 2013.

Form factor wise the models are the same. This means that they are of similar size and form.

Processor

The two models have the same generation of Intel processors. We think that the 4 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

Memory

The Lenovo ThinkCentre M93 Small Pro has 4 RAM slots while the HP ProDesk 400 G1 SFF 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.

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. Additionally, if you will be needing a lot of RAM, better go for the Lenovo ThinkCentre M93 Small Pro as it has the ability to run 32 GB of RAM. The HP ProDesk 400 G1 SFF can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

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.

Unfortunately, only the Lenovo ThinkCentre M93 Small Pro has a DisplayPort. The HP ProDesk 400 G1 SFF does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

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 M93 Small Pro is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 400 G1 SFF has 3 slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the HP ProDesk 400 G1 SFF, nor the Lenovo ThinkCentre M93 Small Pro has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

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!

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.
