Differences between Acer Veriton X2665g and Lenovo ThinkCentre M800 Small

If you are looking for a more modern desktop, then you should go with the Acer Veriton X2665g which was released in 2019. The Lenovo ThinkCentre M800 Small is older and entered production in 2015.

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 Acer Veriton X2665g as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M800 Small is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Lenovo ThinkCentre M800 Small has 4 RAM slots while the Acer Veriton X2665g 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 Acer Veriton X2665g is using the faster 2666 MT/s RAM. The Lenovo ThinkCentre M800 Small 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 Lenovo ThinkCentre M800 Small as it has the ability to run 64 GB of RAM. The Acer Veriton X2665g can do a bit less at max 32 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. What is nice about the Acer Veriton X2665g, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Lenovo ThinkCentre M800 Small 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 Lenovo ThinkCentre M800 Small comes with 2 ports, while the Acer Veriton X2665g has only 1. If you are planning to use multiple monitors, the Lenovo ThinkCentre M800 Small is the better choice.

The Acer Veriton X2665g comes with an HDMI port, while the Lenovo ThinkCentre M800 Small 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 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 Acer Veriton X2665g. Sadly, the Lenovo ThinkCentre M800 Small 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 Acer Veriton X2665g comes with a decent 180 Watt PSU, but the Lenovo ThinkCentre M800 Small has a more powerful one rated at 210 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.
