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.
