Differences between Acer Veriton X2640g and Lenovo ThinkCentre E73 Small

If you are looking for a more modern desktop, then you should go with the Acer Veriton X2640g which was released in 2015. The Lenovo ThinkCentre E73 Small is older and entered production in 2013.

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 X2640g as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre E73 Small is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (2 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.

The Acer Veriton X2640g is using the faster 2133 MT/s RAM. The Lenovo ThinkCentre E73 Small is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Acer Veriton X2640g as it has the ability to run 32 GB of RAM. The Lenovo ThinkCentre E73 Small can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Acer Veriton X2640g has 8 USB ports. The Lenovo ThinkCentre E73 Small 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. 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 E73 Small has a DisplayPort. The Acer Veriton X2640g 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 E73 Small is better equipped as it comes with 3 SATA slot(s), while the Acer Veriton X2640g has slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Lenovo ThinkCentre E73 Small, nor the Acer Veriton X2640g has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

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 Lenovo ThinkCentre E73 Small comes with a decent 180 Watt PSU, but the Acer Veriton X2640g has a more powerful one rated at 220 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.
