Differences between Dell OptiPlex 3040M and HP ProDesk 600 G4 SFF
If a more modern desktop is what you are looking for, then you should go with the HP ProDesk 600 G4 SFF which was released in 2018. The Dell OptiPlex 3040M is older and entered production in 2015.
If you are looking for the smaller form factor the Dell OptiPlex 3040M is the right one for you. It is smaller than the HP ProDesk 600 G4 SFF 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 600 G4 SFF as it is running a newer generation CPU. This is not to say that Dell OptiPlex 3040M is bad - it can still run some powerful CPUs, albeit being an older generation.
The HP ProDesk 600 G4 SFF has 4 RAM slots while the Dell OptiPlex 3040M has only 2 slot(s). Of course this is not something to worry about. Just make sure you take it into consideration when planning how much RAM will your system be using.The HP ProDesk 600 G4 SFF is using the faster 2666 MT/s RAM. The Dell OptiPlex 3040M is slower by supporting RAM speeds of only up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 600 G4 SFF as it has the ability to run 64 GB of RAM. The Dell OptiPlex 3040M can do a bit less at max 16 GB. Most of the times, this should be sufficient for most users.
In total the HP ProDesk 600 G4 SFF has 11 USB ports. The Dell OptiPlex 3040M is inferior in this regard and packs 6 USB ports. What is nice about the HP ProDesk 600 G4 SFF, is that it has 5 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 3040M has no such port, thus restricting your transfer speeds a bit.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP ProDesk 600 G4 SFF comes with 2 ports, while the Dell OptiPlex 3040M has only 1.
The Dell OptiPlex 3040M comes with an HDMI port, while the HP ProDesk 600 G4 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 port 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 HP ProDesk 600 G4 SFF is better equipped as it comes with 3 SATA 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 600 G4 SFF. Sadly, the Dell OptiPlex 3040M has no such slot, and you will be forced to use the SATA interface instead.Remark: Make sure that the M.2 slot supports the PCIe (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 6 Gb/s, while the PCIe 3.0 x4 will support speeds up to 32 Gb/s!
Having a Power Supply Unit with high power rating is important if you are going to use components which require extra power. The Dell OptiPlex 3040M comes with a decent 65 Watt PSU, but the HP ProDesk 600 G4 SFF has a more powerful one rated at 180 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.
