Differences between Acer Veriton X4640g and Dell OptiPlex 3040M

Both computers, the Dell OptiPlex 3040M and the Acer Veriton X4640g, were released during the same year - 2015.

If you are looking for the smaller form factor the Dell OptiPlex 3040M is the right one for you. It is smaller than the Acer Veriton X4640g and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 6 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

Memory

The Acer Veriton X4640g has 4 RAM slots while the Dell OptiPlex 3040M 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 X4640g is using the faster 2133 MT/s RAM. The Dell OptiPlex 3040M 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 X4640g as it has the ability to run 32 GB of RAM. The Dell OptiPlex 3040M 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 X4640g has 10 USB ports. The Dell OptiPlex 3040M 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.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Acer Veriton X4640g comes with 2 ports, while the Dell OptiPlex 3040M has only 1. If you are planning to use multiple monitors, the Acer Veriton X4640g is the better choice.

The Dell OptiPlex 3040M comes with an HDMI port, while the Acer Veriton X4640g 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 X4640g is better equipped as it comes with 3 SATA slot(s), while the Dell OptiPlex 3040M has 1 slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell OptiPlex 3040M, nor the Acer Veriton X4640g 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 Dell OptiPlex 3040M comes with a decent 65 Watt PSU, but the Acer Veriton X4640g 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.
