Acer Veriton M6640g vs. Acer Veriton S2690g
Comparison and Differences
Differences between Acer Veriton M6640g and Acer Veriton S2690g
If you are looking for a more modern desktop, then you should go with the Acer Veriton S2690g which was released in 2021. The Acer Veriton M6640g is older and entered production in 2016.
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 Acer Veriton S2690g as it is running a newer generation CPU. This is not to say that Acer Veriton M6640g is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Acer Veriton M6640g has 4 RAM slots while the Acer Veriton S2690g 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 S2690g is using the faster 3200 MT/s RAM. The Acer Veriton M6640g 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 Acer Veriton S2690g as it has the ability to run 64 GB of RAM. The Acer Veriton M6640g 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 S2690g has 8 USB ports. The Acer Veriton M6640g is inferior in this regard and packs 0 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 M6640g comes with 2 ports, while the Acer Veriton S2690g has only 1. If you are planning to use multiple monitors, the Acer Veriton M6640g is the better choice.
The Acer Veriton S2690g comes with an HDMI port, while the Acer Veriton M6640g 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 M6640g is better equipped as it comes with 5 SATA slot(s), while the Acer Veriton S2690g has 4 slot(s).
When your goal is to have the fastest SSD transfer speeds, an M.2 interface is crucial. Thus, it is good that both models have M.2 SSD slots. Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to invest in SATA drives anymore.
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
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 300 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.
