Differences between Acer Veriton X2665g and HP ProDesk 490 G2 Microtower

If you are looking for a more modern desktop, then you should go with the Acer Veriton X2665g which was released in 2019. The HP ProDesk 490 G2 Microtower is older and entered production in 2014.

If you are looking for the smaller form factor the Acer Veriton X2665g is the right one for you. It is smaller than the HP ProDesk 490 G2 Microtower 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 Acer Veriton X2665g as it is running a newer generation CPU. This is not to say that HP ProDesk 490 G2 Microtower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The HP ProDesk 490 G2 Microtower has 4 RAM slots while the Acer Veriton X2665g 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 Acer Veriton X2665g is using the faster 2666 MT/s RAM. The HP ProDesk 490 G2 Microtower 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

Both models have the same amount of USB ports for total count of 8. If this is not enough, using a USB hub is always a viable option. What is nice about the Acer Veriton X2665g, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the HP ProDesk 490 G2 Microtower has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.

Unfortunately, only the Acer Veriton X2665g has a DisplayPort. The HP ProDesk 490 G2 Microtower does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

The Acer Veriton X2665g comes with an HDMI port, while the HP ProDesk 490 G2 Microtower 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 slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 3 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.

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 Acer Veriton X2665g. Sadly, the HP ProDesk 490 G2 Microtower 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 Acer Veriton X2665g comes with a decent 180 Watt PSU, but the HP ProDesk 490 G2 Microtower has a more powerful one rated at 300 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.
