Differences between Acer Veriton X2640g and HP ProDesk 490 G3 Microtower

Both computers, the HP ProDesk 490 G3 Microtower and the Acer Veriton X2640g, were released during the same year - 2015.

If you are looking for the smaller form factor the Acer Veriton X2640g is the right one for you. It is smaller than the HP ProDesk 490 G3 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 X2640g as it is running a newer generation CPU. This is not to say that HP ProDesk 490 G3 Microtower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The HP ProDesk 490 G3 Microtower has 4 RAM slots while the Acer Veriton X2640g 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.

None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 2133. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 490 G3 Microtower as it has the ability to run 64 GB of RAM. The Acer Veriton X2640g can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.

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. 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 HP ProDesk 490 G3 Microtower has a DisplayPort. The Acer Veriton X2640g does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.

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 HP ProDesk 490 G3 Microtower is better equipped as it comes with 3 SATA slot(s), while the Acer Veriton X2640g has slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the HP ProDesk 490 G3 Microtower, nor the Acer Veriton X2640g 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 Acer Veriton X2640g comes with a decent 220 Watt PSU, but the HP ProDesk 490 G3 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.
