Differences between Alienware Aurora R5 and HP ProDesk 600 G3 SFF

If you are looking for a more modern desktop, then you should go with the HP ProDesk 600 G3 SFF which was released in 2017. The Alienware Aurora R5 is older and entered production in 2015.

If you are looking for the smaller form factor the HP ProDesk 600 G3 SFF is the right one for you. It is smaller than the Alienware Aurora R5 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 HP ProDesk 600 G3 SFF as it is running a newer generation CPU. This is not to say that Alienware Aurora R5 is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (4 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.

None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 2400. 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 R5 has 13 USB ports. The HP ProDesk 600 G3 SFF is inferior in this regard and packs 11 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Alienware Aurora R5, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the HP ProDesk 600 G3 SFF 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 HP ProDesk 600 G3 SFF has a DisplayPort. The Alienware Aurora R5 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 R5 is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 600 G3 SFF has 2 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 HP ProDesk 600 G3 SFF comes with a decent 180 Watt PSU, but the Alienware Aurora R5 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.
