Dell Inspiron 620s vs. HP ProDesk 600 G6 Microtower
Comparison and Differences
Differences between Dell Inspiron 620s and HP ProDesk 600 G6 Microtower
If you are looking for a more modern desktop, then you should go with the HP ProDesk 600 G6 Microtower which was released in 2020. The Dell Inspiron 620s is older and entered production in 2012.
If you are looking for the smaller form factor the Dell Inspiron 620s is the right one for you. It is smaller than the HP ProDesk 600 G6 Microtower 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 HP ProDesk 600 G6 Microtower as it is running a newer generation CPU. This is not to say that Dell Inspiron 620s is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The HP ProDesk 600 G6 Microtower has 4 RAM slots while the Dell Inspiron 620s 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 600 G6 Microtower is using the faster 3200 MT/s RAM. The Dell Inspiron 620s 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 600 G6 Microtower as it has the ability to run 128 GB of RAM. The Dell Inspiron 620s can do a bit less at max 8 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the HP ProDesk 600 G6 Microtower has 10 USB ports. The Dell Inspiron 620s 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 HP ProDesk 600 G6 Microtower, is that it has 3 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell Inspiron 620s 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 HP ProDesk 600 G6 Microtower has a DisplayPort. The Dell Inspiron 620s does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
The Dell Inspiron 620s comes with an HDMI port, while the HP ProDesk 600 G6 Microtower 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 4 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
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 600 G6 Microtower. Sadly, the Dell Inspiron 620s 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 Dell Inspiron 620s comes with a decent 250 Watt PSU, but the HP ProDesk 600 G6 Microtower has a more powerful one rated at 550 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.
