QNAP TVS-473-16G 4-Bay NAS Review

Rating: 8.5.

QNAP’s latest TVS NAS series, the TVS-473 sits under the company’s SMB midrange label and is available as four, six and eight-bay units. The TVS-473 is the 4-bay entry level model of the series; a 4-bay NAS that so packed full of features it can be used for just about any purpose.


For the TVS-*73 series, QNAP has joined forces with AMD so all three units in the range are powered by an AMD R-Series Quad-core SoC, an RX-421BD to be exact, which runs at 2.1 GHz (burst up to 3.4 GHz).

The RX-421BD is a compact 28nm SoC measuring just 37mm x 29mm with a 2MB L2 cache supporting DDR3-2133 or DDR4-2400 memory speeds. The main core provides a single PCI-e Gen 3 x8 or PCI-e Gen 2/3 x4 lane with support for up to three display outputs. The PCH on the chip itself offers SATA, SD Card, SPI, 4-8 USB 2.0 and 4 USB 3.0 ports connectivity.  The integrated Radeon R7 graphic core has a maximum clock speed of 800MHz with 8 GPU Compute Units and 512 Shader cores. The RX-421BD has a TDP range between 12-35W.

The TVS-473 comes in three basic memory versions, all using DDR4-2133MHz; an entry-level 8GB model (TVS-473-8G), 16GB (TVS-473-16G) –  the model QNAP sent for review, and the flagship 64GB unit (TVS-473-64G).

We mentioned the TVS-473 was packed full of features, well how about this for a list, deep breath; up to 64GB of DDR4 support, AES-NI hardware encryption engine, four, yes four LAN ports, two M.2 SATA SSD slots, SSD cache support, USB 3.1 (10Gbps), 10GbE expandability via one of the two PCI-e Gen 3.0 slots, dual HDMI output, not forgetting hardware-assisted 4K video decoding and encoding acceleration.

Embedded AMD Radeon R7 Graphics.
Built in AES-NI hardware encryption engine
16GB memory.
Dual HDMI multimedia output (4K, 1080p).
2-year warranty.

    Scrolled down to the comments expecting to see the chap who trawls the internet to post his negative story on QNAP C&P’ing his woe but he’s not made it yet.

    I feel like I’ve been waiting forever for a proper review of this device—so it’s great to see your review (and that you rate it!) 🙂
    I really like the TVS-x82 series with it’s dedicated SSD (and M.2) slots, but couldn’t justify the price. Although still expensive, at least this is somewhat cheaper yet still has M.2 slots for caching etc. Nice compromise, imo. The R7 graphics are also interesting.

    What is the frame rate of the the graphics chipset? I know the TVS-471 was 30 FPS so I am hoping this is markedly better and therefore better suited to also serve as a media center on top of separately being a media server.

    Also which memory configuration did you end up getting, 8 GB, 16 GB, or 64 GB? Does QNAP take the cheap way out and populate all 4 SODIMM slots with the smallest possible RAM modules possible for each system memory size which thereby forces you to replace all four SODIMMs when you come around and upgrade them? Or, are they civilized and only use two of the four available SODIMM slots so you can simply add 2 more SODIMMs without wasting any RAM?
