Quick review of Dell Precision Tower 3620: medium-range workstation solution – VnReview

The Dell Precision Tower 3620 has a lot of options, with the same thing as a strong configuration, dedicated graphics card to suit the needs and pockets of users.

Unlike personal computers, when users can choose and build configurations in accordance with their needs, businesses when equipping computers often consider synchronous products with advantages of saving. installation time, higher stability.

This is especially true for businesses operating in the field of design, architecture or construction, modeling. Computer companies have workstation products that meet this need. With Dell, it's the Dell Precision Tower product line.

The Dell Precision Tower 3620 is a mid-range workstation, with many configuration options, but the common feature is that it is equipped with a dedicated NVIDIA Quadro graphics card. The price of the product ranges from 24 to 38 million VND. The product in this article has a reference price through Synnex FPT distributor of VND 33.9 million with the following detailed configuration:

Design and upgrade capabilities

The Dell Precision Tower 3620 has a unique design of a synchronous computer: the black case is easy to disassemble and fully equipped with the necessary connection port. The height of the machine is only 35 cm but the width of 17.5 cm and weighing up to 9.1 kg should be suitable for laying on the floor rather than on the table.

Connections on the front

On the front, the company offers up to 4 USB ports including up to 2 high-speed USB 3.0 ports, a headphone and mic jack, and a horizontal DVD RW drive. On the back, there are 6 more USB ports and 4 of them also get speed 3.0, PS / 2 ports for both keys and mouse, serial port, Gigabit Ethernet port and video output ports on DisplayPort, HDMI. However, the main export task is in the NVIDIA Quadro K1200 graphics card. The card has 4 mini-DisplayPort 1.2 output ports, and the manufacturer also has 4 mini-DisplayPort cables to standard DisplayPort.

Connections on the back

The side of the hip is designed to be opened with a lever, without removing the screw, so cleaning the machine or upgrading the components is easy. The two most easily upgraded components are RAM and hard drive, SSD. It has 4 DDR4 RAM slots, and defaulted to install 2 8GB sticks. The motherboard allows maximum upgrade to 64GB RAM, supports both ECC RAM and regular RAM. With internal memory, there are 2 SATA3 ports with M.2 2280 slot so users have many options to upgrade. The chassis allows for a maximum of 2 3.5-inch or 4-inch 2.5-drive drives, along with an M.2 SSD.

The space inside the case is relatively open

In addition, there are still 2 PCI-Express 3.0 x4 ports, supporting Dell Precision Ultra-Speed ​​SSDs (using PCI-Express port) or mounting expansion cards. With 290W power supply, the original configuration only consumes up to 160W, users can plug in some expansion cards without worrying about missing power.

The machine still has a tray to install the hard drive, SSD

With 4 RAM slots, it supports up to 64GB RAM, can install ECC RAM to increase performance and stability

The remaining PCI and PCI-Express slots have additional cards with SSDs and expansion cards

It comes with a set of wired Dell keyboards and mice. The design of the keys is simple, square but fully integrated multimedia control keys on the row of keys F. The keyboard has a full size, chiclet style for feeling pretty good typing, long journey and bouncing.

The mouse has a medium-sized machine, designed to hold hands and is suitable for both right-handed and left-handed people. The shell of the mouse also uses rough plastic material like keys, perhaps taking a long time will reduce "sharpness" rather than glossy plastic material.

Performance, temperature and power consumption

As a workstation geared toward computing needs and 3D imaging, the Dell Precision Tower 3620 is also equipped with a powerful configuration. Intel Core i7-6700 processor with 4 cores, 8 streams with 3.4GHz default speed and Turbo Boost up to 4GHz. 16GB of available RAM is plenty, but the NVIDIA Quadro K1200 dedicated graphics card is also worth noting.

Intel Core i7-6700 processor and NVIDIA Quadro K1200 graphics card are noteworthy details in the configuration of the device.

This machine is preinstalled with Fedora OS Workstation version. This operating system fully satisfies the basic use needs such as web surfing, office processing, watching movies or listening to music. However, many specialized software only run on Windows, so buyers still need to install Microsoft operating system to maximize the performance. To evaluate the performance of the machine, we installed the latest version of Windows 10 1803.

Although there are enough applications to meet normal needs, even if there is an application store to download more, the Fedora operating system is still limited if used for work.

With a powerful configuration, the performance of this workstation is too abundant for most common use. Even when using the machine to render, export movies according to the writer's work needs, with less elaborate effects, the machine still responds well. With Adobe Premiere Pro, the CUDA export option is enabled by default so that the GPU supports the CPU in rendering and reduces video output time.

The TDP (temperature limit) level of the CPU is only 65W, so it operates cool, the CPU temperature when operating at the highest level is only about 80 degrees Celsius and the machine does not have the "squeeze" pulse when operating badly.

Intel Core i7-6700 CPU scores high on performance evaluation applications like Cinebench R15 or Geekbench 4

16GB of RAM is quite generous to surf the web with dozens of open tabs at the same time, and for many applications that require high processing capacity, a large amount of RAM will help the machine handle smoother.

Details make the most affected machine performance is a Toshiba 1TB hard drive, clocked at 7200 rpm. The speed of feedback, random data access of the hard drive cannot be compared to an SSD, if used daily, users can realize this limitation. However, if using a machine for heavy work, it takes hours to complete, the difference may not be as clear.

Even if it is a high-speed mechanical hard drive, the performance of the hard drive in this machine is not comparable to that of SSDs

The Quadro K1200 dedicated graphics card may be the main reason why users consider a workstation. In fact, when there is a need to buy a device for work, the buyer will be the one who understands which software needs to meet the software, and needs the corresponding hardware. The Quadro K1200 is 3 years old, and NVIDIA now has a newer Pascal-based card line. However, based on cost, K1200 can still meet users who need moderate performance in 3D and CAD modeling applications.

As a professional graphics card, the performance of the Quadro K1200 3DMark evaluation application is not too impressive.

To evaluate performance in rendering applications, we use SPECviewperf 13. This software recreates processes in real rendering applications like 3Ds Max, Maya, and Solidworks … Sessions The new version 13 was released in May last year, and the results of this release were not comparable to version 12. Below is the evaluation result of Dell Precision Tower 3620:

Temperature is not a big problem with Dell Precision Tower 3620. When using AIDA64 software with Furmark to squeeze maximum CPU, VGA and memory power for 1 hour, the hottest CPU temperature is only 80 degree, and GPU is about 90 degrees. This is still an acceptable level, but if you want better heat dissipation, you can replace the larger air blower or install an exhaust fan.

When in sleep mode (idle), the device consumes about 34W of electricity per hour

At the maximum operating level, the machine consumes about 140 – 160W electricity

In idle mode (idle), each hour consumes about 34W electricity. When pressing the machine to run at full capacity as the above temperature test, this machine also only consumes a maximum of about 160W / hour. So if the machine runs heavy and continuous, it must be about 6 hours before the end of 1 power. Excessive power supply of 290W to meet this configuration.


Unlike computers of general users, computers for work require high stability, save time to select and install, good technical support and cost can be more extensive. So businesses who want to equip their employees to do heavy work can consider synchronous solutions like Dell Precision Tower.

This machine has a lot of configuration options, from the lowest version using Intel Xeon E3-1225 v5, RAM 8GB and Quadro P600 graphics card to the highest version using Intel E3-1270 v5, 16GB RAM and card Quadro M2000 graphics. This makes it easy for managers to choose the best and most suitable configuration for their pocket.

Anyway, this is just a mid-range workstation, so there are no advanced options such as a more multi-core processor, a graphics card from Quadro P4000 or higher … The configurations are only equipped with regular RAM. not ECC RAM, no SSD available and no Windows built-in. This is also the point that buyers need to consider.
