Dell XPS 8910 vs. HP ProDesk 600 G1 SFF
Comparison and Differences
Differences between Dell XPS 8910 and HP ProDesk 600 G1 SFF
If you are looking for the smaller form factor the HP ProDesk 600 G1 SFF is the right one for you. It is smaller than the Dell XPS 8910 and will fit more easily under your desk.
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 XPS 8910 as it is running a newer generation CPU. This is not to say that HP ProDesk 600 G1 SFF 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 Dell XPS 8910 is using the faster 2133 MT/s RAM. The HP ProDesk 600 G1 SFF is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell XPS 8910 as it has the ability to run 64 GB of RAM. The HP ProDesk 600 G1 SFF can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.
In total the Dell XPS 8910 has 11 USB ports. The HP ProDesk 600 G1 SFF is inferior in this regard and packs 10 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Dell XPS 8910, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the HP ProDesk 600 G1 SFF 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.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP ProDesk 600 G1 SFF comes with 2 ports, while the Dell XPS 8910 has only 1. If you are planning to use multiple monitors, the HP ProDesk 600 G1 SFF is the better choice.
The Dell XPS 8910 comes with an HDMI port, while the HP ProDesk 600 G1 SFF 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 4 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell XPS 8910, nor the HP ProDesk 600 G1 SFF 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!
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The HP ProDesk 600 G1 SFF comes with a decent 240 Watt PSU, but the Dell XPS 8910 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.
