Differences between Alienware Area 51 R4 and Fujitsu Esprimo P920

If you are looking for a more modern desktop, then you should go with the Alienware Area 51 R4 which was released in 2015. The Fujitsu Esprimo P920 is older and entered production in 2014.

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 P920 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 Alienware Area 51 R4 as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo P920 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.

The Alienware Area 51 R4 is using the faster 2933 MT/s RAM. The Fujitsu Esprimo P920 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 Area 51 R4 as it has the ability to run 64 GB of RAM. The Fujitsu Esprimo P920 can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.

Ports

Both models have the same amount of USB ports for total count of 12. If this is not enough, using a USB hub is always a viable option. 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 P920 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 P920 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 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 Fujitsu Esprimo P920 is better equipped as it comes with 6 SATA slot(s), while the Alienware Area 51 R4 has 4 slot(s).

If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the Alienware Area 51 R4. Sadly, the Fujitsu Esprimo P920 has no such slot, and you will be forced to use the SATA interface instead.

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 P920 comes with a decent 280 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.
