Dell G5 5000 vs. Dell OptiPlex 3090 Tower
Comparison and Differences
Differences between Dell G5 5000 and Dell OptiPlex 3090 Tower
If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3090 Tower which was released in 2021. The Dell G5 5000 is older and entered production in 2020.
Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.
Processor
The two models have the same generation of Intel processors. We think that the 10 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.
Memory
The Dell G5 5000 has 4 RAM slots while the Dell OptiPlex 3090 Tower 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 Dell G5 5000 is using the faster 2933 MT/s RAM. The Dell OptiPlex 3090 Tower is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell G5 5000 as it has the ability to run 128 GB of RAM. The Dell OptiPlex 3090 Tower can do a bit less at max 64 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Dell G5 5000 has 9 USB ports. The Dell OptiPlex 3090 Tower is inferior in this regard and packs 8 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Dell G5 5000, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 3090 Tower has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.
Unfortunately, only the Dell OptiPlex 3090 Tower has a DisplayPort. The Dell G5 5000 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.
SATA slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 3 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
When your goal is to have the fastest SSD transfer speeds, an M.2 interface is crucial. Thus, it is good that both models have M.2 SSD slots. Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to invest in SATA drives anymore.
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 Dell OptiPlex 3090 Tower comes with a decent 260 Watt PSU, but the Dell G5 5000 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.
