Differences between Alienware Aurora R9 and Dell OptiPlex 5080M

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 5080M which was released in 2020. The Alienware Aurora R9 is older and entered production in 2018.

If you are looking for the smaller form factor the Dell OptiPlex 5080M is the right one for you. It is smaller than the Alienware Aurora R9 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 5080M as it is running a newer generation CPU. This is not to say that Alienware Aurora R9 is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Alienware Aurora R9 has 4 RAM slots while the Dell OptiPlex 5080M 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 Alienware Aurora R9 is using the faster 3000 MT/s RAM. The Dell OptiPlex 5080M 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 Alienware Aurora R9 has 14 USB ports. The Dell OptiPlex 5080M is inferior in this regard and packs 6 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the Alienware Aurora R9 as it has 2 USB3.1 ports (the Dell OptiPlex 5080M has 1).

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 5080M comes with 2 ports, while the Alienware Aurora R9 has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 5080M is the better choice.

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 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 Alienware Aurora R9 is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 5080M 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 5080M comes with a decent 130 Watt PSU, but the Alienware Aurora R9 has a more powerful one rated at 850 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.
