TVS-673 Turbo vNAS from QNAP is a very complex product for handling various tasks, while its hardware based on AMD is upgradeable in terms of RAM and expansion cards. While the model we have tested runs with 8GB of RAM, there are also two other models available, one with 16GB, but also one with no less than 64GB of DDR4, for running even more application modules and virtual machines at once. The AMD R-Series RX-421BD Quad-Core SoC runs at a base speed of 2.1GHz, while in burst it can climb up to 3.4GHz; it does also feature an embedded Radeon R7 Graphics Processor which drives the two HDMI orts in the back.
