Acer Veriton M6650g vs. Dell OptiPlex 7090 M
Comparison and Differences
Differences between Acer Veriton M6650g and Dell OptiPlex 7090 M
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 7090 M which was released in 2021. The Acer Veriton M6650g is older and entered production in 2018.
If you are looking for the smaller form factor the Dell OptiPlex 7090 M is the right one for you. It is smaller than the Acer Veriton M6650g 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 7090 M 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.
Memory
The Acer Veriton M6650g has 4 RAM slots while the Dell OptiPlex 7090 M 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 7090 M is using the faster 3200 MT/s RAM. The Acer Veriton M6650g is slower by supporting RAM speeds of up to 2400 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 64 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.
Ports
In total the Acer Veriton M6650g has 10 USB ports. The Dell OptiPlex 7090 M 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. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the Acer Veriton M6650g as it has 2 USB3.1 ports (the Dell OptiPlex 7090 M has 1).
The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.
The Acer Veriton M6650g comes with an HDMI port, while the Dell OptiPlex 7090 M 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 7090 M has 0 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 M. 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!
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 7090 M comes with a decent 180 Watt PSU, but the Acer Veriton M6650g 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.
