Differences between Acer Veriton X2660g and Lenovo ThinkCentre M800 Tower

If you are looking for a more modern desktop, then you should go with the Acer Veriton X2660g which was released in 2018. The Lenovo ThinkCentre M800 Tower is older and entered production in 2015.

If you are looking for the smaller form factor the Acer Veriton X2660g is the right one for you. It is smaller than the Lenovo ThinkCentre M800 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 Acer Veriton X2660g as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M800 Tower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Lenovo ThinkCentre M800 Tower has 4 RAM slots while the Acer Veriton X2660g 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 X2660g is using the faster 2666 MT/s RAM. The Lenovo ThinkCentre M800 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 Lenovo ThinkCentre M800 Tower as it has the ability to run 64 GB of RAM. The Acer Veriton X2660g 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 X2660g, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Lenovo ThinkCentre M800 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 Lenovo ThinkCentre M800 Tower comes with 2 ports, while the Acer Veriton X2660g has only 1. If you are planning to use multiple monitors, the Lenovo ThinkCentre M800 Tower is the better choice.

The Acer Veriton X2660g comes with an HDMI port, while the Lenovo ThinkCentre M800 Tower 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 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 Acer Veriton X2660g is better equipped as it comes with 4 SATA slot(s), while the Lenovo ThinkCentre M800 Tower has 3 slot(s).

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 X2660g. Sadly, the Lenovo ThinkCentre M800 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.
