Differences between Dell OptiPlex 7090 MT and HP ProDesk 600 G6 SFF

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 7090 MT which was released in 2021. The HP ProDesk 600 G6 SFF is older and entered production in 2020.

If you are looking for the smaller form factor the HP ProDesk 600 G6 SFF is the right one for you. It is smaller than the Dell OptiPlex 7090 MT 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 7090 MT as it is running a newer generation CPU. This is not to say that HP ProDesk 600 G6 SFF is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (4 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.

None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 3200. In addition, you will be able to install the same amount of RAM in both models, and most probably 128 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.

Ports

In total the HP ProDesk 600 G6 SFF has 10 USB ports. The Dell OptiPlex 7090 MT is inferior in this regard and packs 9 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. Both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. This is especially crucial if you are using external drives on a regular basis.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 7090 MT comes with 4 ports, while the HP ProDesk 600 G6 SFF has only 2. If you are planning to use multiple monitors, the Dell OptiPlex 7090 MT is the better choice.

The Dell OptiPlex 7090 MT comes with an HDMI port, while the HP ProDesk 600 G6 SFF 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 OptiPlex 7090 MT is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 600 G6 SFF has 3 slot(s).

An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the Dell OptiPlex 7090 MT has 1 M.2 slots while the HP ProDesk 600 G6 SFF comes with just 1.

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 HP ProDesk 600 G6 SFF comes with a decent 210 Watt PSU, but the Dell OptiPlex 7090 MT has a more powerful one rated at 500 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.
