Acer Veriton M6650g vs. HP ProDesk 400 G4 SFF
Comparison and Differences
Differences between Acer Veriton M6650g and HP ProDesk 400 G4 SFF
If you are looking for a more modern desktop, then you should go with the Acer Veriton M6650g which was released in 2018. The HP ProDesk 400 G4 SFF is older and entered production in 2017.
If you are looking for the smaller form factor the HP ProDesk 400 G4 SFF is the right one for you. It is smaller than the Acer Veriton M6650g and will fit more easily under your desk.
Processor
The two models have the same generation of Intel processors. We think that the 7 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.
Memory
The Acer Veriton M6650g has 4 RAM slots while the HP ProDesk 400 G4 SFF 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.
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 2400. 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 HP ProDesk 400 G4 SFF is inferior in this regard and packs 8 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Acer Veriton M6650g, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the HP ProDesk 400 G4 SFF 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.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Acer Veriton M6650g comes with 2 ports, while the HP ProDesk 400 G4 SFF has only 1. If you are planning to use multiple monitors, the Acer Veriton M6650g is the better choice.
The Acer Veriton M6650g comes with an HDMI port, while the HP ProDesk 400 G4 SFF 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 HP ProDesk 400 G4 SFF has 2 slot(s).
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the HP ProDesk 400 G4 SFF, nor the Acer Veriton M6650g 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 HP ProDesk 400 G4 SFF 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.
