Differences between HP EliteDesk 800 G5 SFF and Lenovo ThinkCentre M700 Tower

If you are looking for a more modern desktop, then you should go with the HP EliteDesk 800 G5 SFF which was released in 2019. The Lenovo ThinkCentre M700 Tower is older and entered production in 2015.

If you are looking for the smaller form factor the HP EliteDesk 800 G5 SFF is the right one for you. It is smaller than the Lenovo ThinkCentre M700 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 EliteDesk 800 G5 SFF as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M700 Tower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The HP EliteDesk 800 G5 SFF has 4 RAM slots while the Lenovo ThinkCentre M700 Tower has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.

The HP EliteDesk 800 G5 SFF is using the faster 2666 MT/s RAM. The Lenovo ThinkCentre M700 Tower is slower by supporting RAM speeds of up to 2133 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G5 SFF as it has the ability to run 128 GB of RAM. The Lenovo ThinkCentre M700 Tower 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 HP EliteDesk 800 G5 SFF has 11 USB ports. The Lenovo ThinkCentre M700 Tower is inferior in this regard and packs 6 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the HP EliteDesk 800 G5 SFF, is that it has 5 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Lenovo ThinkCentre M700 Tower 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 HP EliteDesk 800 G5 SFF comes with 2 ports, while the Lenovo ThinkCentre M700 Tower has only 1. If you are planning to use multiple monitors, the HP EliteDesk 800 G5 SFF 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 3 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 HP EliteDesk 800 G5 SFF. Sadly, the Lenovo ThinkCentre M700 Tower 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

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 250 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.
