Model Cores (Threads) Base frequency Turbo
Core i5 8500 6(6) 3.0 GHz 4.1 GHz
Core i5 8600 6(6) 3.1 GHz 4.3 GHz
Core i7 8700 6(12) 3.2 GHz 4.6 GHz

Memory

HP EliteDesk 800 G4 Mini has two RAM slots. This is more than enough for most users. For those of you who need extra flexibility and RAM size, go for a model with 4 memory slots.

To cover the needs of your OS, games, and apps, HP EliteDesk 800 G4 Mini supports up to 32 GB of SODIMM DDR4-2666 RAM. For office work, home use, and light gaming we recommend 8GB of RAM. For everything else, use 16GB or more.

Faster RAM speeds permit your processor to access the data stored inside the memory faster. This is important for the overall speed of your system. The motherboard of the HP EliteDesk 800 G4 Mini supports RAM speeds of up to 2666 MT/s.

Wi-Fi Support

HP EliteDesk 800 G4 Mini supports Wi-Fi and Bluetooth combo card with the on-board M.2 2230 (Wi-Fi/BT) slot. The card contains a Wi-Fi module that supports various Wi-Fi standards, as well as a Bluetooth module. It is small circuit board that is designed to fit into a dedicated slot on the motherboard.

Keep in mind that the card is not always included and you have to install one yourself.

Ports

Ports are important and often people don't think about them when buying a PC. For example, if you don't have enough USB ports, using external devices becomes problematic. Before you buy any system, considering your use case, check the number of external devices you are going to use and plan the number of the extension ports accordingly.

USB ports

The HP EliteDesk 800 G4 Mini comes with seven USB ports in total. Having more USB ports is always better, but also pay attention to the version of those USB ports. Higher version ports support faster transfer speeds. It is nice to see that the model has a USB 3.1 port. This interface is using 10Gb/s connection and it's very useful when you transfer big files to external drives.

Video ports

The DisplayPort (DP) is the most widely used digital interface for transmitting digital video and audio between display devices and PCs. It is good to see that the HP EliteDesk 800 G4 Mini is featuring a DisplayPort 1.2. The post version is important if you target higher resolutions with high refresh rate. Although, ver. 1.2 is completely fine for most users, if possible, aim for the higher versions DisplayPort.

The HDMI port is another digital video port you can use to connect external display. It has very similar capabilities to the DisplayPort with few exceptions. However, the HP EliteDesk 800 G4 Mini doesn't have one. This is not a problem if there is on-board DisplayPort.

*Please keep in mind in order to use the video ports available through the motherboard, you need a CPU with integrated graphics card. If you have a dedicated GPU, use his ports instead.

SSD storage - M.2 sockets and SATA ports

The SATA port is one of the places where you can connect a stora gedevice. The HP EliteDesk 800 G4 Mini comes with one SATA port(s). Not enough SATA ports might limit your options for additional storage devices. Think about your use case and decide if the SATA ports provided by this model will be sufficient.

HP EliteDesk 800 G4 Mini has also two M.2 socket(s) that supports both PCIe NVMe (PCIe 3.0 x4) and SATA M.2 drives with speed of up to 4 GB/s. This configuration works very well for both gaming and work related tasks.

The M.2 PCIe SSD connector in combination with an NVMe drive allows for higher transfer rates, compared to the old SATA interface. In some situations, NVMe device connected to the M.2 PCIe socket can be more than 5 times faster.
