Acer Veriton X2660g vs. Fujitsu Esprimo P758
Comparison and Differences
Differences between Acer Veriton X2660g and Fujitsu Esprimo P758
Both computers, the Acer Veriton X2660g and the Fujitsu Esprimo P758, were released during the same year - 2018.
If you are looking for the smaller form factor the Acer Veriton X2660g is the right one for you. It is smaller than the Fujitsu Esprimo P758 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 Fujitsu Esprimo P758 as it is running a newer generation CPU. This is not to say that Acer Veriton X2660g is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Fujitsu Esprimo P758 has 4 RAM slots while the Acer Veriton X2660g 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 2666. Additionally, if you will be needing a lot of RAM, better go for the Fujitsu Esprimo P758 as it has the ability to run 64 GB of RAM. The Acer Veriton X2660g can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Fujitsu Esprimo P758 has 13 USB ports. The Acer Veriton X2660g 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. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the Fujitsu Esprimo P758 as it has 3 USB3.1 ports (the Acer Veriton X2660g has 2).
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Fujitsu Esprimo P758 comes with 2 ports, while the Acer Veriton X2660g has only 1. If you are planning to use multiple monitors, the Fujitsu Esprimo P758 is the better choice.
The Acer Veriton X2660g comes with an HDMI port, while the Fujitsu Esprimo P758 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 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 Fujitsu Esprimo P758 is better equipped as it comes with 5 SATA slot(s), while the Acer Veriton X2660g has 4 slot(s).
When your goal is to have the fastest SSD transfer speeds, an M.2 interface is crucial. Thus, it is good that both models have M.2 SSD slots. Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to invest in SATA drives anymore.
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 X2660g comes with a decent 250 Watt PSU, but the Fujitsu Esprimo P758 has a more powerful one rated at 280 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.
