Differences between Dell XPS 8900 and Lenovo ThinkCentre M72e Tiny

If you are looking for a more modern desktop, then you should go with the Dell XPS 8900 which was released in 2015. The Lenovo ThinkCentre M72e Tiny is older and entered production in 2012.

If you are looking for the smaller form factor the Lenovo ThinkCentre M72e Tiny is the right one for you. It is smaller than the Dell XPS 8900 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 Dell XPS 8900 as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M72e Tiny is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Dell XPS 8900 has 4 RAM slots while the Lenovo ThinkCentre M72e Tiny 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 Dell XPS 8900 is using the faster 2133 MT/s RAM. The Lenovo ThinkCentre M72e Tiny 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 Dell XPS 8900 as it has the ability to run 64 GB of RAM. The Lenovo ThinkCentre M72e Tiny can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Dell XPS 8900 has 10 USB ports. The Lenovo ThinkCentre M72e Tiny 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.

The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.

The Dell XPS 8900 comes with an HDMI port, while the Lenovo ThinkCentre M72e Tiny 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 Dell XPS 8900 is better equipped as it comes with 5 SATA slot(s), while the Lenovo ThinkCentre M72e Tiny has 1 slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell XPS 8900, nor the Lenovo ThinkCentre M72e Tiny 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 Lenovo ThinkCentre M72e Tiny comes with a decent 65 Watt PSU, but the Dell XPS 8900 has a more powerful one rated at 460 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.
