Acer Veriton ES2740g vs. Dell OptiPlex 5090 M
Comparison and Differences
Differences between Acer Veriton ES2740g and Dell OptiPlex 5090 M
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 5090 M which was released in 2021. The Acer Veriton ES2740g is older and entered production in 2019.
If you are looking for the smaller form factor the Dell OptiPlex 5090 M is the right one for you. It is smaller than the Acer Veriton ES2740g 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 5090 M as it is running a newer generation CPU. This is not to say that Acer Veriton ES2740g 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 5090 M is using the faster 3200 MT/s RAM. The Acer Veriton ES2740g 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 5090 M as it has the ability to run 64 GB of RAM. The Acer Veriton ES2740g 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 ES2740g has 8 USB ports. The Dell OptiPlex 5090 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. What is nice about the Dell OptiPlex 5090 M, is that it has 1 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Acer Veriton ES2740g 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 5090 M has a DisplayPort. The Acer Veriton ES2740g 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 ES2740g comes with an HDMI port, while the Dell OptiPlex 5090 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 Dell OptiPlex 5090 M is better equipped as it comes with 3 SATA slot(s), while the Acer Veriton ES2740g has 2 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
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 5090 M comes with a decent 130 Watt PSU, but the Acer Veriton ES2740g 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.
