Acer Veriton M4660g vs. Alienware Aurora R4
Comparison and Differences
Differences between Acer Veriton M4660g and Alienware Aurora R4
If you are looking for a more modern desktop, then you should go with the Acer Veriton M4660g which was released in 2018. The Alienware Aurora R4 is older and entered production in 2012.
If you are looking for the smaller form factor the Alienware Aurora R4 is the right one for you. It is smaller than the Acer Veriton M4660g 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 Acer Veriton M4660g as it is running a newer generation CPU. This is not to say that Alienware Aurora R4 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 Acer Veriton M4660g is using the faster 2666 MT/s RAM. The Alienware Aurora R4 is slower by supporting RAM speeds of up to 1866 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Acer Veriton M4660g as it has the ability to run 124 GB of RAM. The Alienware Aurora R4 can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Acer Veriton M4660g has 8 USB ports. The Alienware Aurora R4 is inferior in this regard and packs 5 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.
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.
The Acer Veriton M4660g comes with an HDMI port, while the Alienware Aurora R4 does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).
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 Acer Veriton M4660g is better equipped as it comes with 5 SATA slot(s), while the Alienware Aurora R4 has 3 slot(s).
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Alienware Aurora R4, nor the Acer Veriton M4660g has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.
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 Acer Veriton M4660g comes with a decent 300 Watt PSU, but the Alienware Aurora R4 has a more powerful one rated at 875 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.
