Acer Veriton M4660g vs. Dell OptiPlex 7090 MT
Comparison and Differences
Differences between Acer Veriton M4660g and Dell OptiPlex 7090 MT
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 7090 MT which was released in 2021. The Acer Veriton M4660g is older and entered production in 2018.
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 Dell OptiPlex 7090 MT as it is running a newer generation CPU. This is not to say that Acer Veriton M4660g is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
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 7090 MT is using the faster 3200 MT/s RAM. The Acer Veriton M4660g is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 7090 MT as it has the ability to run 128 GB of RAM. The Acer Veriton M4660g can do a bit less at max 124 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Dell OptiPlex 7090 MT has 9 USB ports. The Acer Veriton M4660g 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. What is nice about the Dell OptiPlex 7090 MT, is that it has 3 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Acer Veriton M4660g 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.
Unfortunately, only the Dell OptiPlex 7090 MT has a DisplayPort. The Acer Veriton M4660g does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
The HDMI video interface is broadly used and the majority of the external displays support it. Thus, it is nice to see that both models have this video interface. If you are going to use multiple monitors go with the Dell OptiPlex 7090 MT which has 2 ports. The Acer Veriton M4660g has only 1 ports.
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 M4660g is better equipped as it comes with 5 SATA slot(s), while the Dell OptiPlex 7090 MT 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 7090 MT. Sadly, the Acer Veriton M4660g 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 M4660g comes with a decent 300 Watt PSU, but the Dell OptiPlex 7090 MT has a more powerful one rated at 500 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.
