Dell Vostro 460 vs. HP ProDesk 400 G1 Mini
Comparison and Differences
Differences between Dell Vostro 460 and HP ProDesk 400 G1 Mini
If you are looking for the smaller form factor the HP ProDesk 400 G1 Mini is the right one for you. It is smaller than the Dell Vostro 460 and will fit more easily under your desk.
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 G1 Mini as it is running a newer generation CPU. This is not to say that Dell Vostro 460 is bad - it can still run some powerful CPUs, albeit being an older generation.
The Dell Vostro 460 has 4 RAM slots while the HP ProDesk 400 G1 Mini 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 G1 Mini is using the faster 1600 MT/s RAM. The Dell Vostro 460 is slower by supporting RAM speeds of up to 1333 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 16 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.
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 HP ProDesk 400 G1 Mini has a DisplayPort. The Dell Vostro 460 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 460 comes with an HDMI port, while the HP ProDesk 400 G1 Mini 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 Dell Vostro 460 is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 400 G1 Mini has 1 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 G1 Mini. Sadly, the Dell Vostro 460 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!
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 G1 Mini comes with a decent 65 Watt PSU, but the Dell Vostro 460 has a more powerful one rated at 350 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.
