Comparison and Differences
Differences between Alienware Aurora R13 and Dell OptiPlex 7090 M
Both computers, the Dell OptiPlex 7090 M and the Alienware Aurora R13, were released during the same year - 2021.
If you are looking for the smaller form factor the Dell OptiPlex 7090 M is the right one for you. It is smaller than the Alienware Aurora R13 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 Alienware Aurora R13 as it is running a newer generation CPU. This is not to say that Dell OptiPlex 7090 M is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Alienware Aurora R13 has 4 RAM slots while the Dell OptiPlex 7090 M 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 R13 is using the faster 4400 MT/s RAM. The Dell OptiPlex 7090 M is slower by supporting RAM speeds of up to 3200 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Alienware Aurora R13 as it has the ability to run 128 GB of RAM. The Dell OptiPlex 7090 M 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 R13 has 12 USB ports. The Dell OptiPlex 7090 M 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 R13 as it has 2 USB3.1 ports (the Dell OptiPlex 7090 M has 1).
Unfortunately, only the Dell OptiPlex 7090 M has a DisplayPort. The Alienware Aurora R13 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 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 R13 is better equipped as it comes with 3 SATA slot(s), while the Dell OptiPlex 7090 M has 0 slot(s).
An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the Dell OptiPlex 7090 M has 1 M.2 slots while the Alienware Aurora R13 comes with just 1.
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 7090 M comes with a decent 180 Watt PSU, but the Alienware Aurora R13 has a more powerful one rated at 750 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.
