Differences between Acer Veriton X6640g and Dell OptiPlex 3000 Tower

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3000 Tower which was released in 2022. The Acer Veriton X6640g is older and entered production in 2015.

If you are looking for the smaller form factor the Acer Veriton X6640g is the right one for you. It is smaller than the Dell OptiPlex 3000 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 Dell OptiPlex 3000 Tower as it is running a newer generation CPU. This is not to say that Acer Veriton X6640g is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Acer Veriton X6640g has 4 RAM slots while the Dell OptiPlex 3000 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 Dell OptiPlex 3000 Tower is using the faster 3200 MT/s RAM. The Acer Veriton X6640g 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 Dell OptiPlex 3000 Tower as it has the ability to run 64 GB of RAM. The Acer Veriton X6640g 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 Acer Veriton X6640g has 10 USB ports. The Dell OptiPlex 3000 Tower is inferior in this regard and packs 8 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.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Acer Veriton X6640g comes with 2 ports, while the Dell OptiPlex 3000 Tower has only 1. If you are planning to use multiple monitors, the Acer Veriton X6640g is the better choice.

The Dell OptiPlex 3000 Tower comes with an HDMI port, while the Acer Veriton X6640g 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 Dell OptiPlex 3000 Tower. Sadly, the Acer Veriton X6640g 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 X6640g comes with a decent 220 Watt PSU, but the Dell OptiPlex 3000 Tower has a more powerful one rated at 300 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.
