The difference between Dell OptiPlex 3070 SFF and HP ProDesk 400 G5 Microtower

Welcome to our page comparing the Dell OptiPlex 3070 SFF vs. the HP ProDesk 400 G5 Microtower. Are you trying to choose between the two desktop computers unsure which one is more suitable for you? This page will try to highlight the differences between the two models: the Dell OptiPlex 3070 SFF vs. HP ProDesk 400 G5 Microtower. Don't forget to also check the comparison table where you will find detailed specification.

If a more modern desktop is what you are looking for, then you should go with the Dell OptiPlex 3070 SFF which was released in 2019. The HP ProDesk 400 G5 Microtower is a bit older and entered production in 2018.

For some use cases size is important. If you are looking for the smaller form factor the Dell OptiPlex 3070 SFF is the right one for you. It is smaller than the HP ProDesk 400 G5 Microtower and will fit easier under your desk.

The 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 3070 SFF as it is running a newer generation CPU. This is not to say that HP ProDesk 400 G5 Microtower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

RAM slots is where your insert your RAM sticks. Each of those two models have 2 RAM slots which should be taken into account when planning how much and what combination of RAM it\'s going to be used. 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 2666. You will be able to install the same amount of RAM in both models, and most probably 32 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

None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals you will need to look at other models.

The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. It is good to see that both of the models come with a DisplayPort.

The Dell OptiPlex 3070 SFF comes with an HDMI port which is version 1.4, while the HP ProDesk 400 G5 Microtower does not support the HDMI interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DP to HDMI).

SATA slot is where SSD, HDD and Optical Disk Drives are connected. More SATA slots will allow you to have more Disk Drives running at the same time. In this regard the HP ProDesk 400 G5 Microtower is better equipped as it comes with 3 SATA slots, while the Dell OptiPlex 3070 SFF has only 2 slots.

When your goal is to have the fastest transfer speeds for your SSD, M.2 interface is crucial. Thus, it is good that both models have an M.2 SSD slot(s). Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to buy SATA drives anymore.
Remark: If you want the fastest M.2 SSD interface, make sure that the slot supports the PCIe interface. Compared to the SATA III, the PCIe 3.0 x4 is more than 5 times faster (6Gb/s vs. 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 OptiPlex 3070 SFF comes with a decent 200 Watt PSU, but the HP ProDesk 400 G5 Microtower has a more powerful one rated at 310 Watts. Choosing either one depends on your specific requirements and use case.
