Differences between Alienware Area 51 R4 and Alienware Area 51 R5

Both computers, the Alienware Area 51 R4 and the Alienware Area 51 R5, were released during the same year - 2015.

Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.

Processor

The two models have the same generation of Intel processors. We think that the 10 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 Area 51 R5 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 R5 has 13 USB ports. The Alienware Area 51 R4 is inferior in this regard and packs 12 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. Both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. This is especially crucial if you are using external drives on a regular basis.

Nowadays, almost every new computer comes equipped with a DisplayPort. However, none of the devices being compared here has one. Don't worry though, DisplayPort adapters are very cheap and you can get virtually 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

Looking at the Power Supply Unit (PSU) of the two models we don't see any differences. For either of them you get a maximum power of 1500 Watts. However be careful, many models have more than one power supply option. When buying your computer, it is a good idea to get a version with the most powerful PSU. This will potentially allow you to upgrade to a more powerful GPU for example.
