QNAP TVS-675 NAS features Zhaoxin KaiXian KX-U6580 x86 processor

QNAP has been trying something different in several in their new NAS recently. Last month, we covered QMiroPlus-201W that combines an Arm router and Intel NAS into one device, and now the company has announced another x86 NAS, but not based on Intel or AMD processor, but instead Zhaoxin’s 2.5 GHz eight-core KaiXian KX-U6580 processor.

QNAP TVS-675 NAS comes with 8GB RAM by default, six drive bays for hard drives or SSD’s, two M.2 2280 slots for SATA or NVMe storage, as well as two PCIe 3.0 x4 slots for networking, storage, or other expansion cards. The NAS also features 2.5GbE wired connectivity and an HDMI 2.0 to connect a display.

TVS-675 portsThe NAS runs QTS 4.5.3 embedded Linux by default, but it’s also possible to install QuTS hero and Ubuntu 18.04/20.04 for a dual boot system. The device ships with an Ethernet cable, a power cord, various screws to mount the drivers, two M.2 SSD heatsinks, drive tray keys, and a Quick Installation Guide (QIG).

QNAP also offers a wide range of PCIe expansions cards for networking (5GbE, 10 GbE, WiFI 6, etc..), storage (M.2, SAS, etc..) , or a combination of the two.

Zhaoxin KX-U6580, and other KX-6000 series processors, are said to offer lower latency while running multi-task applications, hardware 4K video
transcoding, 4K video output via HDMI 2.0, and VT-x and IO virtualization
for running multiple virtual machines (VM).

While Zhaoxin x86 (and Arm) processors have mainly been found in products sold in mainline China, QNAP TVS-675 will be distributed worldwide. Performance-wise Zhaoxin KX-U6580 appears to offer performance similar to an Intel Celeron J4105 quad-core Gemini Lake processor, mostly due to the eight cores as single-thread performance is on the weaker side. It does not seem to be the most efficient processor either based on the NAS 40+ W idle power.
