Differences between Dell OptiPlex 7010 DT and Dell Vostro 3668

If you are looking for a more modern desktop, then you should go with the Dell Vostro 3668 which was released in 2016. The Dell OptiPlex 7010 DT is older and entered production in 2012.

If you are looking for the smaller form factor the Dell Vostro 3668 is the right one for you. It is smaller than the Dell OptiPlex 7010 DT 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 3668 as it is running a newer generation CPU. This is not to say that Dell OptiPlex 7010 DT is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Dell OptiPlex 7010 DT has 4 RAM slots while the Dell Vostro 3668 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 Vostro 3668 is using the faster 2400 MT/s RAM. The Dell OptiPlex 7010 DT 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 OptiPlex 7010 DT as it has the ability to run 32 GB of RAM. The Dell Vostro 3668 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 OptiPlex 7010 DT has 10 USB ports. The Dell Vostro 3668 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 Dell OptiPlex 7010 DT has a DisplayPort. The Dell Vostro 3668 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 3668 comes with an HDMI port, while the Dell OptiPlex 7010 DT 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 Vostro 3668 is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 7010 DT 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 Dell OptiPlex 7010 DT, nor the Dell Vostro 3668 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 Dell Vostro 3668 comes with a decent 240 Watt PSU, but the Dell OptiPlex 7010 DT has a more powerful one rated at 250 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.
