Alienware Aurora R9 vs. HP ProDesk 600 G5 SFF
Comparison and Differences
Differences between Alienware Aurora R9 and HP ProDesk 600 G5 SFF
Both computers, the Alienware Aurora R9 and the HP ProDesk 600 G5 SFF, were released during the same year - 2018.
If you are looking for the smaller form factor the HP ProDesk 600 G5 SFF is the right one for you. It is smaller than the Alienware Aurora R9 and will fit more easily under your desk.
Processor
The two models have the same generation of Intel processors. We think that the 9 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.
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.
The Alienware Aurora R9 is using the faster 3000 MT/s RAM. The HP ProDesk 600 G5 SFF 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 HP ProDesk 600 G5 SFF as it has the ability to run 128 GB of RAM. The Alienware Aurora R9 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 R9 has 14 USB ports. The HP ProDesk 600 G5 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. 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 HP ProDesk 600 G5 SFF as it has 5 USB3.1 ports (the Alienware Aurora R9 has 2).
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP ProDesk 600 G5 SFF comes with 2 ports, while the Alienware Aurora R9 has only 1. If you are planning to use multiple monitors, the HP ProDesk 600 G5 SFF is the better choice.
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 R9 is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 600 G5 SFF has 3 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 G5 SFF comes with a decent 180 Watt PSU, but the Alienware Aurora R9 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.
