Alienware Area 51 R4 vs. Fujitsu Esprimo P5011
Comparison and Differences
Differences between Alienware Area 51 R4 and Fujitsu Esprimo P5011
If you are looking for a more modern desktop, then you should go with the Fujitsu Esprimo P5011 which was released in 2021. The Alienware Area 51 R4 is older and entered production in 2015.
If you are looking for the smaller form factor the Alienware Area 51 R4 is the right one for you. It is smaller than the Fujitsu Esprimo P5011 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 Fujitsu Esprimo P5011 as it is running a newer generation CPU. This is not to say that Alienware Area 51 R4 is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Alienware Area 51 R4 has 4 RAM slots while the Fujitsu Esprimo P5011 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 Fujitsu Esprimo P5011 is using the faster 3200 MT/s RAM. The Alienware Area 51 R4 is slower by supporting RAM speeds of up to 2933 MT/s. 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 Area 51 R4 has 12 USB ports. The Fujitsu Esprimo P5011 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. What is nice about the Alienware Area 51 R4, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Fujitsu Esprimo P5011 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 Fujitsu Esprimo P5011 has a DisplayPort. The Alienware Area 51 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 4 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
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 Fujitsu Esprimo P5011 comes with a decent 300 Watt PSU, but the Alienware Area 51 R4 has a more powerful one rated at 1500 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.
