Acer Veriton X6630g vs. HP ProDesk 400 G6 SFF
Comparison and Differences
Differences between Acer Veriton X6630g and HP ProDesk 400 G6 SFF
If you are looking for a more modern desktop, then you should go with the HP ProDesk 400 G6 SFF which was released in 2019. The Acer Veriton X6630g is older and entered production in 2013.
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 HP ProDesk 400 G6 SFF as it is running a newer generation CPU. This is not to say that Acer Veriton X6630g is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Acer Veriton X6630g has 4 RAM slots while the HP ProDesk 400 G6 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.
The HP ProDesk 400 G6 SFF is using the faster 2666 MT/s RAM. The Acer Veriton X6630g is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 400 G6 SFF as it has the ability to run 64 GB of RAM. The Acer Veriton X6630g 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 8. If this is not enough, using a USB hub is always a viable option. 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 X6630g comes with 2 ports, while the HP ProDesk 400 G6 SFF has only 1. If you are planning to use multiple monitors, the Acer Veriton X6630g is the better choice.
The Acer Veriton X6630g comes with an HDMI port, while the HP ProDesk 400 G6 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 X6630g is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 400 G6 SFF has 2 slot(s).
If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the HP ProDesk 400 G6 SFF. Sadly, the Acer Veriton X6630g has no such slot, and you will be forced to use the SATA interface instead.
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 G6 SFF comes with a decent 180 Watt PSU, but the Acer Veriton X6630g has a more powerful one rated at 220 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.
