Fujitsu Esprimo P9012 vs. Fujitsu Esprimo P958
Comparison and Differences
Differences between Fujitsu Esprimo P9012 and Fujitsu Esprimo P958
Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.
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 P9012 as it is running a newer generation CPU. This is not to say that Fujitsu Esprimo P958 is bad - it can still run some powerful CPUs, albeit being an older generation.
Both models have have equal amount of ram slots (4 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.
The Fujitsu Esprimo P9012 is using the faster 3200 MT/s RAM. The Fujitsu Esprimo P958 is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Fujitsu Esprimo P9012 as it has the ability to run 128 GB of RAM. The Fujitsu Esprimo P958 can do a bit less at max 64 GB. Most of the times, this should be sufficient for the majority of users.
In total the Fujitsu Esprimo P958 has 13 USB ports. The Fujitsu Esprimo P9012 is inferior in this regard and packs 12 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 P9012 as it has 5 USB3.1 ports (the Fujitsu Esprimo P958 has 4).
The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.
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 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 5 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the Fujitsu Esprimo P9012 has 1 M.2 slots while the Fujitsu Esprimo P958 comes with just 1.
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!
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Fujitsu Esprimo P958 comes with a decent 280 Watt PSU, but the Fujitsu Esprimo P9012 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.
