Dell Vostro 3660 vs. HP EliteDesk 800 G8 Tower
Comparison and Differences
Differences between Dell Vostro 3660 and HP EliteDesk 800 G8 Tower
If you are looking for a more modern desktop, then you should go with the HP EliteDesk 800 G8 Tower which was released in 2021. The Dell Vostro 3660 is older and entered production in 2016.
If you are looking for the smaller form factor the Dell Vostro 3660 is the right one for you. It is smaller than the HP EliteDesk 800 G8 Tower 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 EliteDesk 800 G8 Tower as it is running a newer generation CPU. This is not to say that Dell Vostro 3660 is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The HP EliteDesk 800 G8 Tower has 4 RAM slots while the Dell Vostro 3660 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 EliteDesk 800 G8 Tower is using the faster 3200 MT/s RAM. The Dell Vostro 3660 is slower by supporting RAM speeds of up to 2133 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G8 Tower as it has the ability to run 128 GB of RAM. The Dell Vostro 3660 can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the HP EliteDesk 800 G8 Tower has 11 USB ports. The Dell Vostro 3660 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 HP EliteDesk 800 G8 Tower, is that it has 4 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell Vostro 3660 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 EliteDesk 800 G8 Tower has a DisplayPort. The Dell Vostro 3660 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 Vostro 3660 comes with an HDMI port, while the HP EliteDesk 800 G8 Tower 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 EliteDesk 800 G8 Tower. Sadly, the Dell Vostro 3660 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 Vostro 3660 comes with a decent 240 Watt PSU, but the HP EliteDesk 800 G8 Tower 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.
