Differences between Dell OptiPlex 3090 M and Dell OptiPlex Tower 7010 2023

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex Tower 7010 2023 which was released in 2023. The Dell OptiPlex 3090 M is older and entered production in 2021.

If you are looking for the smaller form factor the Dell OptiPlex 3090 M is the right one for you. It is smaller than the Dell OptiPlex Tower 7010 2023 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 Tower 7010 2023 as it is running a newer generation CPU. This is not to say that Dell OptiPlex 3090 M is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (2 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.

The Dell OptiPlex Tower 7010 2023 is using the faster 3200 MT/s RAM. The Dell OptiPlex 3090 M is slower by supporting RAM speeds of up to 2933 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 64 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 Dell OptiPlex Tower 7010 2023 has 8 USB ports. The Dell OptiPlex 3090 M is inferior in this regard and packs 5 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.

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

The Dell OptiPlex Tower 7010 2023 comes with an HDMI port, while the Dell OptiPlex 3090 M 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 Tower 7010 2023 is better equipped as it comes with 3 SATA slot(s), while the Dell OptiPlex 3090 M has 1 slot(s).

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 M comes with a decent 65 Watt PSU, but the Dell OptiPlex Tower 7010 2023 has a more powerful one rated at 300 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.
