Acer Veriton L4630g vs. Dell OptiPlex 3040M
Comparison and Differences
Differences between Acer Veriton L4630g and Dell OptiPlex 3040M
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3040M which was released in 2015. The Acer Veriton L4630g is older and entered production in 2014.
If you are looking for the smaller form factor the Dell OptiPlex 3040M is the right one for you. It is smaller than the Acer Veriton L4630g 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 3040M as it is running a newer generation CPU. This is not to say that Acer Veriton L4630g 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.
None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 1600. In addition, you will be able to install the same amount of RAM in both models, and most probably 16 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 L4630g has 10 USB ports. The Dell OptiPlex 3040M 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. 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 L4630g comes with 2 ports, while the Dell OptiPlex 3040M has only 1. If you are planning to use multiple monitors, the Acer Veriton L4630g is the better choice.
The Dell OptiPlex 3040M comes with an HDMI port, while the Acer Veriton L4630g 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 1 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell OptiPlex 3040M, nor the Acer Veriton L4630g has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.
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 3040M comes with a decent 65 Watt PSU, but the Acer Veriton L4630g has a more powerful one rated at 135 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.
