Differences between Dell Vostro 3690 and Lenovo ThinkCentre M700 Tower

If you are looking for a more modern desktop, then you should go with the Dell Vostro 3690 which was released in 2021. The Lenovo ThinkCentre M700 Tower is older and entered production in 2015.

If you are looking for the smaller form factor the Dell Vostro 3690 is the right one for you. It is smaller than the Lenovo ThinkCentre M700 Tower 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 Vostro 3690 as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M700 Tower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (2 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 Dell Vostro 3690 is using the faster 2933 MT/s RAM. The Lenovo ThinkCentre M700 Tower is slower by supporting RAM speeds of up to 2133 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell Vostro 3690 as it has the ability to run 64 GB of RAM. The Lenovo ThinkCentre M700 Tower 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 Dell Vostro 3690 has 8 USB ports. The Lenovo ThinkCentre M700 Tower 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. 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.

Unfortunately, only the Lenovo ThinkCentre M700 Tower has a DisplayPort. The Dell Vostro 3690 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

The Dell Vostro 3690 comes with an HDMI port, while the Lenovo ThinkCentre M700 Tower 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 Lenovo ThinkCentre M700 Tower is better equipped as it comes with 3 SATA slot(s), while the Dell Vostro 3690 has 2 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 Dell Vostro 3690. Sadly, the Lenovo ThinkCentre M700 Tower 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 Lenovo ThinkCentre M700 Tower comes with a decent 250 Watt PSU, but the Dell Vostro 3690 has a more powerful one rated at 260 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.
