Review fast Dell Precision Tower 3620: mid-range workstation solution – VnReview

Dell Precision Tower 3620 has a lot of options with a strong configuration, dedicated graphics card to suit the needs and budget of users.

Unlike personal computers, when users can choose and build the configuration to suit the needs of use, businesses equipped with computers often consider synchronized products with the advantages of being economical. Installation time, higher stability.

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

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

Design and upgradability

The Dell Precision Tower 3620 features the unique design of a synchronous computer: a black case, easy to remove and fully equipped with necessary connectors. The height of the device is only 35 cm but the width is 17.5 cm and weighs up to 9.1 kg so it is suitable for putting on the floor rather than on the table.

The connector on the front

On the front, the company is equipped with 4 USB ports including 2 high-speed USB 3.0 ports, headphone jack, mic and DVD RW drive horizontally. On the back, there are 6 more USB ports and 4 of them also reach 3.0, PS / 2 port for both keys and mouse, serial port, Gigabit Ethernet network port and main output ports such as DisplayPort, HDMI. However, the main task of the export lies at the NVIDIA Quadro K1200 graphics card. The card has 4 mini-DisplayPort 1.2 video output ports, and in the box the manufacturer also equips 4 mini-DisplayPort cables to the standard DisplayPort.

The side is designed to open with a lever, without removing the screws, so cleaning the device or upgrading components is very easy. The two most easily upgraded components are RAM and hard drive, SSD. It has 4 DDR4 RAM slots, and comes with 2 8GB sticks by default. The motherboard allows for a maximum upgrade to 64GB of RAM, supporting both ECC and normal RAM types. With internal memory, due to the 2 SATA3 ports along with M.2 2280 slot, users have a lot of options for upgrading. The chassis allows to install up to 2 3.5-inch drives or 4 2.5-inch drives, and 1 M.2 SSD.

Space inside the chassis is relatively airy

In addition, the machine still has 2 PCI-Express 3.0 x4 ports, supporting mounting the Dell Precision Ultra-Speed ​​SSD drive (using the PCI-Express port) or attaching an expansion card. With the 290W power supply, the original configuration only consumed a maximum of 160W, users can plug in some expansion cards without worrying about power shortage.

The machine still has a tray to attach an extra hard drive and SSD

With 4 RAM slots, the device supports up to 64GB of RAM, can also be fitted with ECC RAM to increase performance and stability.

The remaining PCI and PCI-Express slots have an SSD, expansion card

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

The mouse has a moderate size, ergonomic design and is suitable for both right and left hand users. The shell of the mouse also uses a rough plastic material like the key, perhaps a longer use will be less “down” than the glossy plastic material.

Performance, temperature and power consumption

As a workstation aiming to calculate and build 3D images, Dell Precision Tower 3620 is also equipped with a powerful configuration. Intel Core i7-6700 processor with 4 cores, 8 threads with default speed of 3.4GHz and Turbo Boost up to 4GHz. Available RAM memory is quite abundant 16GB, in addition to NVIDIA Quadro K1200 dedicated graphics card is also noticeable.

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

This device comes preloaded with Workora operating system Fedora. This operating system fully meets the basic needs of using such as web surfing, office processing, watching movies or listening to music. However, many specialized software only runs on Windows, so buyers still need to install additional Microsoft operating systems to maximize performance. To evaluate the performance of the machine, we installed the latest Windows 10 version 1803.

Although there are enough applications to meet the normal needs, including an app 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 overwhelming for most common tasks. Even when using the machine to render, export movies according to the needs of the writer, less complicated editing, the machine still responds well. With Adobe Premiere Pro software, the CUDA kernel export option is enabled by default so that the GPU supports the CPU in rendering and reduces video export time.

The TDP (temperature limit) of the CPU is only 65W, so the operation is cool, the CPU temperature when operating at the highest level is only about 80 degrees Celsius and the machine does not have the phenomenon of “squeezing” the pulse when doing heavy work.

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

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

The detail that makes the performance of the machine most affected is a 1TB Toshiba hard drive, speed of 7200 rpm. The speed of response, random data access of the hard drive is not comparable to SSD, if used daily, users can realize this limitation. However, if you use the machine for heavy work, takes many hours to complete, the difference may not be as obvious.

Even if it is a high-speed mechanical hard drive, the performance of the hard drive in this machine cannot be compared to SSDs.

A dedicated Quadro K1200 graphics card may be the main reason users consider a workstation. In fact, when there is a need to buy a machine for work, the buyer will be the one who understands most what the machine needs to meet, and the corresponding hardware. Quadro K1200 is 3 years old, and now NVIDIA has a newer Pascal-based card series. However, based on the price, K1200 is still able to meet users who need moderate performance in 3D and CAD modeling applications.

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

To evaluate performance in rendering applications, we use the SPECviewperf 13 review. This is a software that recreates processes in real-world rendering applications such as 3Ds Max, Maya, Solidworks … Version 13 was released last May, and the results of this version are not comparable with version 12. Here are the results of the evaluation of Dell Precision Tower 3620:

The temperature is not a big deal with the Dell Precision Tower 3620. When using AIDA64 software with Furmark to squeeze the maximum power of the CPU, VGA and memory for 1 hour, the hottest CPU temperature is just over 80 degrees, and the GPU is almost 90 degrees. This is still an acceptable level, but if you want to dissipate heat better, you can replace the larger exhaust fan or install an exhaust fan.

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

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

In idle mode, each hour consumes about 34W of electricity. When pressed the machine runs at full capacity as the above temperature test, this machine also consumes a maximum of about 160W / hour. So if the machine runs heavy and continuous, it takes more than 6 hours to run out of electricity. The 290W power supply is more than adequate for this configuration.


Unlike a general-purpose computer, a business computer requires a high level of stability, saves installation and installation time, provides good technical support and can be more costly. So businesses that want to equip employees to do heavy work can consider comprehensive solutions such as Dell Precision Tower.

This machine has a lot of configuration options, from the lowest version using Intel Xeon E3-1225 v5 processor, 8GB RAM 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 most appropriate and suitable configuration for their pocket.

Anyway, this is just a mid-range workstation, so there will be no advanced options such as more core processors, graphics cards from Quadro P4000 and above … The configuration is also only available with regular RAM instead. not ECC RAM, without SSD and without Windows installed. This is also the point that buyers need to consider.
