azultec Cube 300


Schloss Holte-Stukenbrock, 22 January 2019 - azultec, provider of an eco-friendly concept for cloud computing, introduces the Cube 300, a unique and highly powerful cloud rendering workstation. In combination with a unique, self-developed ecosystem, rendering in the cloud is to be revolutionized and to become much eco-friendlier by reusing most of the energy consumed by the workstation. In addition, owners of the Cube are rewarded with monthly payments for providing computing power to the cloud network.

From mining PC to cloud rendering workstation

Originally, azultec wanted to build the most efficient miner in the world. To achieve this, they created a complete ecosystem that can recycle the majority of the consumed energy in the form of heat.
During development, azultec shifted its focus to a more lucrative application: rendering.

The need for rendering resources is enormous: in addition to well-known software giants and Hollywood studios, other business segments such as 3D studios, animation studios and advertising agencies also need as much computing power as possible to render their productions. This is where the azultec Cube 300 comes in: thanks to its high computing performance, the water-cooled workstation is predestined for these tasks and the potential revenue for the user is much higher than with mining.

Cloud rendering on the azultec Cube 300

From the factory, every Cube is delivered "plug and play"-ready to the end customer and supports a quick and easy installation – a complex, time-consuming and expensive setup by specialists is not necessary. Thanks to a self-developed operating system and an intuitive dashboard, the customer can monitor the important real-time data of the Cube in a glance.

If you want to make the computing power of the Cube available to azultec's cloud rendering network, you can do so in just a few steps. For this provision, the customer receives a monthly payment, the amount depending on the processing power dedicated to the network.

Example revenue scenario

This example illustrates how lucrative cloud rendering with the Cube 300 can be: take the expected monthly revenue for cloud computing (€600-€2000), subtract the electricity bill (€292), and that leaves you with a positive monthly result of €308 to €1708. The Cube 300 itself has a retail price of €6499 and would be paid off in full within 4 to 21 months. Please note that this is a very conservative calculation, which corresponds to a workload of the Cube of only 25 percent; additionally, the reduction in operating costs through recuperation (see below) has not yet been taken into account.

Reusing heat through recuperation

By design, it’s also possible to effectively reuse the generated heat in your home. For this purpose, each azultec Cube can be connected to heat storage systems, allowing up to 72 percent of the consumed energy to be recuperated. This form of integration can reduce the operating costs of the Cube even further.

Deployable as part of a decentralized cloud storage network

In addition to cloud computing, there is also the option to expand the hard drive space within the Cube and use or deploy it for cloud storage – the latter, of course, also earns you revenue. azultec’s decentralized cloud solution offers the highest level of data safety: all data on the Cube is encrypted and stored externally, so it is not affected by machine failure.

azultec Cube 300: water-cooled super PC for home use

The azultec Cube 300 can be considered a "personal super computer" due to its special features. azultec has extensively researched current cloud rendering and mining solutions and used this information to develop a particularly efficient alternative with a high computing power, thanks to specially adapted graphics cards. Its unique ‘all-in-one’ concept avoids issues that have plagued previous cloud computing hardware. azultec was able to significantly reduce volume and heat development by relying on high-end custom water cooling developed for personal computers. This makes the Cube perfectly suitable for installation in the home.

azultec will initially offer the Cube 300, which is equipped with the following core components: 8x GeForce GTX 1070 (each with 4 GB of GDDR5X), 4 GB of DDR4 RAM, and 2 terabytes of HDD storage. The graphics cards are water-cooled. The power consumption averages at 1450 watts. In practice, the Cube 300 achieves an Octanebench score of 768 points and an Ethereum-hashrate of 310 MHash/s.


CES 2019 Innovation Awards

The CES Innovation Awards is an annual competition honoring outstanding design and engineering in consumer technology products. The azultec Cube 300 was rewarded as an Innovation Awards Honoree* in the category "Sustainability and Eco-Design" at CES 2019. Read more by clicking on this link.


    Price and availability

The first generation of the azultec Cube will be shipped in Q1 2019. The price for the Cube 300 is $6,999/€6,499. The workstations is available today from Amazon and the Aquatuning online store. More information can be found in the press material at the end of this document or requested by e-mail.

Reminder: azultec ICO starts March 5th!

The official launch of the azultec ICO is March 5th, 2019, at 3 pm (CET). This is to optimize the production of water-cooled rendering workstations as well as to finance the development of the world's largest decentralized cloud computing network. Pre-registrations are already accepted!
