Differences between Alienware Aurora R4 and Dell OptiPlex 3020 MT

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3020 MT which was released in 2013. The Alienware Aurora R4 is older and entered production in 2012.

If you are looking for the smaller form factor the Alienware Aurora R4 is the right one for you. It is smaller than the Dell OptiPlex 3020 MT and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 4 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 R4 has 4 RAM slots while the Dell OptiPlex 3020 MT 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 R4 is using the faster 1866 MT/s RAM. The Dell OptiPlex 3020 MT is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Alienware Aurora R4 as it has the ability to run 32 GB of RAM. The Dell OptiPlex 3020 MT can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Dell OptiPlex 3020 MT has 8 USB ports. The Alienware Aurora R4 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.

Unfortunately, only the Dell OptiPlex 3020 MT has a DisplayPort. The Alienware Aurora R4 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 slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 3 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell OptiPlex 3020 MT, nor the Alienware Aurora R4 has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

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 3020 MT comes with a decent 290 Watt PSU, but the Alienware Aurora R4 has a more powerful one rated at 875 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.
