Dell OptiPlex 9020 USFF vs. Dell Vostro 360 AIO
Comparison and Differences
Differences between Dell OptiPlex 9020 USFF and Dell Vostro 360 AIO
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 9020 USFF which was released in 2013. The Dell Vostro 360 AIO is older and entered production in 2012.
If you are looking for the smaller form factor the Dell OptiPlex 9020 USFF is the right one for you. It is smaller than the Dell Vostro 360 AIO 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 9020 USFF as it is running a newer generation CPU. This is not to say that Dell Vostro 360 AIO 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.
The Dell OptiPlex 9020 USFF is using the faster 1600 MT/s RAM. The Dell Vostro 360 AIO is slower by supporting RAM speeds of up to 1333 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 9020 USFF as it has the ability to run 16 GB of RAM. The Dell Vostro 360 AIO can do a bit less at max 8 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 6. 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.
Unfortunately, only the Dell OptiPlex 9020 USFF has a DisplayPort. The Dell Vostro 360 AIO does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.
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 2 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 Dell OptiPlex 9020 USFF. Sadly, the Dell Vostro 360 AIO 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 360 AIO comes with a decent 180 Watt PSU, but the Dell OptiPlex 9020 USFF has a more powerful one rated at 200 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.
