Differences between Alienware Aurora R11 and Dell OptiPlex M 7020 2024

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex M 7020 2024 which was released in 2024. The Alienware Aurora R11 is older and entered production in 2020.

If you are looking for the smaller form factor the Dell OptiPlex M 7020 2024 is the right one for you. It is smaller than the Alienware Aurora R11 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 M 7020 2024 as it is running a newer generation CPU. This is not to say that Alienware Aurora R11 is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Alienware Aurora R11 has 4 RAM slots while the Dell OptiPlex M 7020 2024 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 OptiPlex M 7020 2024 is using the faster 5600 MT/s RAM. The Alienware Aurora R11 is slower by supporting RAM speeds of up to 3400 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 M 7020 2024 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 M 7020 2024 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 R11 as it has 3 USB3.1 ports (the Dell OptiPlex M 7020 2024 has 1).

Unfortunately, only the Dell OptiPlex M 7020 2024 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 M 7020 2024 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 M 7020 2024 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 M 7020 2024 has 1 M.2 slots while the Alienware Aurora R11 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 M 7020 2024 comes with a decent 90 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.
