Acer Veriton M6650g vs. Dell OptiPlex 7000 Tower
Comparison and Differences
Differences between Acer Veriton M6650g and Dell OptiPlex 7000 Tower
Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.
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 7000 Tower as it is running a newer generation CPU. This is not to say that Acer Veriton M6650g is bad - it can still run some powerful CPUs, albeit being an older generation.
Both models have have equal amount of ram slots (4 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 Dell OptiPlex 7000 Tower is using the faster 4400 MT/s RAM. The Acer Veriton M6650g is slower by supporting RAM speeds of up to 2400 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 7000 Tower as it has the ability to run 128 GB of RAM. The Acer Veriton M6650g can do a bit less at max 64 GB. Most of the times, this should be sufficient for the majority of users.
Both models have the same amount of USB ports for total count of 10. If this is not enough, using a USB hub is always a viable option. Both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. This is especially crucial if you are using external drives on a regular basis.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 7000 Tower comes with 3 ports, while the Acer Veriton M6650g has only 2. If you are planning to use multiple monitors, the Dell OptiPlex 7000 Tower is the better choice.
The Acer Veriton M6650g comes with an HDMI port, while the Dell OptiPlex 7000 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 M6650g is better equipped as it comes with 5 SATA slot(s), while the Dell OptiPlex 7000 Tower has 4 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 Dell OptiPlex 7000 Tower. Sadly, the Acer Veriton M6650g 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!
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 500 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.
