Differences between Acer Veriton N4640g 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 N4640g is older and entered production in 2017.

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 M as it is running a newer generation CPU. This is not to say that Acer Veriton N4640g is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (2 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 M is using the faster 3200 MT/s RAM. The Acer Veriton N4640g 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 7090 M as it has the ability to run 64 GB of RAM. The Acer Veriton N4640g can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.

Ports

Both models have the same amount of USB ports for total count of 6. If this is not enough, using a USB hub is always a viable option. What is nice about the Dell OptiPlex 7090 M, is that it has 1 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Acer Veriton N4640g 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 M has a DisplayPort. The Acer Veriton N4640g does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

The Acer Veriton N4640g 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 slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 0 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.

An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the Dell OptiPlex 7090 M has 1 M.2 slots while the Acer Veriton N4640g comes with just 1.

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 N4640g comes with a decent 90 Watt PSU, but the Dell OptiPlex 7090 M has a more powerful one rated at 180 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.
