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 This is important as there are M.2 slots which support only the inferior SATA III interface. Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. However, you can still use a SATA SSD drive which should give you satisfactory performance. Unfortunately, neither the Dell OptiPlex 3020 MT, nor the Dell OptiPlex 7010 MT has one. M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. In this regard the Dell OptiPlex 7010 MT is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 3020 MT has 3 slot(s). More SATA slots will allow you to have more drives running at the same time. SATA ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. Such adapters are cheap so nothing to worry about. If your monitor supports only the HDMI interface, you will need to buy an adapter. If you are planning to use multiple monitors, the Dell OptiPlex 7010 MT is the better choice.
However, the Dell OptiPlex 7010 MT comes with 2 ports, while the Dell OptiPlex 3020 MT has only 1. It is good to see that both models are featuring DisplayPorts. 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.ĭisplayPort is crucial for any desktop machine. In any case, if you miss USB ports, you can always purchase a USB hub. The Dell OptiPlex 3020 MT is inferior in this regard and packs 8 USB ports. In total the Dell OptiPlex 7010 MT has 10 USB ports. Most of the times, this should be sufficient for the majority of users.
The Dell OptiPlex 3020 MT can do a bit less at max 16 GB. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 7010 MT as it has the ability to run 32 GB of RAM. Both models support RAM speeds of up to 1600. None of the desktops has an advantage when it comes to the speed of the RAM being used. Just make sure you take it into consideration when planning how much RAM you are going to use. The Dell OptiPlex 7010 MT has 4 RAM slots while the Dell OptiPlex 3020 MT has only 2 slot(s). This is not to say that Dell OptiPlex 7010 MT is bad - it can still run some powerful CPUs, albeit being an older generation. If your budget allows it, you should go with the Dell OptiPlex 3020 MT as it is running a newer generation CPU. Usually the newer the generation of the CPU, the better the performance and efficiency is. The Dell OptiPlex 7010 MT is older and entered production in 2012.īoth models have the same form factor, meaning reoughtly they have the same phiysical size and form. If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3020 MT which was released in 2013.
Additionally some PSUs don't come with an auxiliary PCIe power connector and you may need to buy a SATA to PCIe power adapter.ĭifferences between Dell OptiPlex 3020 MT and Dell OptiPlex 7010 MT ** As an Amazon associate we earn from qualifying purchases.* Dedicated GPU warning: Check if your particular power supply model has enough power.
