Acer Veriton ES2735g vs. HP ProDesk 400 G5 SFF
Comparison and Differences
Differences between Acer Veriton ES2735g and HP ProDesk 400 G5 SFF
If you are looking for a more modern desktop, then you should go with the Acer Veriton ES2735g which was released in 2019. The HP ProDesk 400 G5 SFF is older and entered production in 2018.
If you are looking for the smaller form factor the HP ProDesk 400 G5 SFF is the right one for you. It is smaller than the Acer Veriton ES2735g 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 ES2735g as it is running a newer generation CPU. This is not to say that HP ProDesk 400 G5 SFF is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
Both models have have equal amount of ram slots (2 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.
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. 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. 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 400 G5 SFF has a DisplayPort. The Acer Veriton ES2735g 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 ES2735g comes with an HDMI port, while the HP ProDesk 400 G5 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 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 400 G5 SFF is better equipped as it comes with 3 SATA slot(s), while the Acer Veriton ES2735g has 2 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
Looking at the Power Supply Unit (PSU) of the two models we don't see any differences. For either of them you get a maximum power of 180 Watts. However be careful, many models have more than one power supply option. When buying your computer, it is a good idea to get a version with the most powerful PSU. This will potentially allow you to upgrade to a more powerful GPU for example.
