Differences between Dell OptiPlex 3070 MT and Dell XPS 8300

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3070 MT which was released in 2019. The Dell XPS 8300 is older and entered production in 2011.

Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.

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 XPS 8300 is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Dell XPS 8300 has 4 RAM slots while the Dell OptiPlex 3070 MT 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 OptiPlex 3070 MT is using the faster 2666 MT/s RAM. The Dell XPS 8300 is slower by supporting RAM speeds of up to 1600 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 32 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.

Ports

In total the Dell XPS 8300 has 10 USB ports. The Dell OptiPlex 3070 MT is inferior in this regard and packs 8 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 3070 MT has a DisplayPort. The Dell XPS 8300 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

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

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 8300 is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 3070 MT has 3 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 OptiPlex 3070 MT. Sadly, the Dell XPS 8300 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 Dell OptiPlex 3070 MT comes with a decent 260 Watt PSU, but the Dell XPS 8300 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.
