Alienware Aurora R11 vs. Dell OptiPlex 3080M
Comparison and Differences
Differences between Alienware Aurora R11 and Dell OptiPlex 3080M
Both computers, the Dell OptiPlex 3080M and the Alienware Aurora R11, were released during the same year - 2020.
If you are looking for the smaller form factor the Dell OptiPlex 3080M is the right one for you. It is smaller than the Alienware Aurora R11 and will fit more easily under your desk.
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 Alienware Aurora R11 has 4 RAM slots while the Dell OptiPlex 3080M 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 R11 is using the faster 3400 MT/s RAM. The Dell OptiPlex 3080M 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 Alienware Aurora R11 as it has the ability to run 128 GB of RAM. The Dell OptiPlex 3080M 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 Alienware Aurora R11 has 15 USB ports. The Dell OptiPlex 3080M 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. What is nice about the Alienware Aurora R11, is that it has 3 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 3080M 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 3080M has a DisplayPort. The Alienware Aurora R11 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
The Dell OptiPlex 3080M comes with an HDMI port, while the Alienware Aurora R11 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 Alienware Aurora R11 is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 3080M 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 3080M comes with a decent 65 Watt PSU, but the Alienware Aurora R11 has a more powerful one rated at 1000 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.
