Differences between HP ProDesk 400 G2 SFF and Lenovo ThinkCentre M92p Tower

If a more modern desktop is what you are looking for, then you should go with the HP ProDesk 400 G2 SFF which was released in 2014. The Lenovo ThinkCentre M92p Tower is older and entered production in 2011.

If you are looking for the smaller form factor the HP ProDesk 400 G2 SFF is the right one for you. It is smaller than the Lenovo ThinkCentre M92p Tower 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 HP ProDesk 400 G2 SFF as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M92p Tower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Lenovo ThinkCentre M92p Tower has 4 RAM slots while the HP ProDesk 400 G2 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 M92p Tower as it has the ability to run 32 GB of RAM. The HP ProDesk 400 G2 SFF can do a bit less at max 16 GB. Most of the times, this should be sufficient for most users.

Ports

Total count of USB ports for both computers is 8. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals you will need to look at other models.

The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. It is good to see that both of the models come with a DisplayPort.

None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter.

SATA port 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 M92p Tower is better equipped as it comes with 4 SATA slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA. Unfortunately, neither the HP ProDesk 400 G2 SFF, nor the Lenovo ThinkCentre M92p Tower has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

Remark: Make sure that the M.2 slot supports the PCIe (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 6 Gb/s, while the PCIe 3.0 x4 will support speeds up to 32 Gb/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 HP ProDesk 400 G2 SFF comes with a decent 240 Watt PSU, but the Lenovo ThinkCentre M92p Tower has a more powerful one rated at 450 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.
