The difference between Dell OptiPlex 3070 MT and Dell OptiPlex 7050 SFF

Welcome to our page comparing the Dell OptiPlex 3070 MT vs. the Dell OptiPlex 7050 SFF. Are you trying to choose between the two desktop computers unsure which one is more suitable for you? This page will try to highlight the differences between the two models: the Dell OptiPlex 3070 MT vs. Dell OptiPlex 7050 SFF. Don't forget to also check the comparison table where you will find detailed specification.

If a more modern desktop is what you are looking for, then you should go with the Dell OptiPlex 3070 MT which was released in 2019. The Dell OptiPlex 7050 SFF is a bit older and entered production in 2017.

For some use cases size is important. If you are looking for the smaller form factor the Dell OptiPlex 7050 SFF is the right one for you. It is smaller than the Dell OptiPlex 3070 MT and will fit easier under your desk.

The 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 OptiPlex 3070 MT as it is running a newer generation CPU. This is not to say that Dell OptiPlex 7050 SFF is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Dell OptiPlex 7050 SFF has 4 RAM slots while the Dell OptiPlex 3070 MT has only 2 slots. Of course this is not something to worry about. Just make sure you take it into account when planning how much RAM will your system be using. The Dell OptiPlex 3070 MT is using the faster 2666 RAM. On the otherhand, the Dell OptiPlex 7050 SFF is slower by supporting RAM speeds of only up to 2400. If you will be needing a lot of RAM, better go for the Dell OptiPlex 7050 SFF as it has the ability to run 64 GB of RAM. The Dell OptiPlex 3070 MT can do a bit less at 32 GB, but this should be enough for most users.

Ports

None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals you will need to look at other models.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell OptiPlex 7050 SFF comes with 2 ports, while the Dell OptiPlex 3070 MT has only 1.

In case your monitor supports HDMI only, you will be happy to hear that both models come with an HDMI port.

SATA slot is where you connect SSD, HDD and Optical Disk Drives. Each of the two models being compared have 3 SATA slots. For most use cases this should be enough but you should decide for yourself.

When your goal is to have the fastest transfer speeds for your SSD, M.2 interface is crucial. Thus, it is good that both models have an M.2 SSD slot(s). Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to buy SATA drives anymore.
Remark: If you want the fastest M.2 SSD interface, make sure that the slot supports the PCIe interface. Compared to the SATA III, the PCIe 3.0 x4 is more than 5 times faster (6Gb/s vs. 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 OptiPlex 7050 SFF comes with a decent 180 Watt PSU, but the Dell OptiPlex 3070 MT has a more powerful one rated at 260 Watts. Choosing either one depends on your specific requirements and use case.
