1. Hardware


High-end workstation customers need power and performance. The CELSIUS M770 delivers performance and a special bonus: a remarkable, elegant, and simple design.


Simplicity is hard work. Elegance is the result of effort. The CELSIUS M770 design is simple and elegant. Yes, it is Fujitsu’s most powerful single-processor workstation. And yet it is easily the company’s most accessible design ever.  This design effort has been rewarded. The workstation won the iF Gold Award 2018 product category.

It is possible to open the workstation and remove nearly every exchangeable component in one minute. Servicing this workstation is easier. Period.



Not only does this workstation support ultra-high-end graphics such as the new NVIDIA Quadro GV100, it supports two of them. The CELSIUS M770 might be a single processor workstation, but users will be surprised. The CELSIUS M770 delivers ten cores with hyper-threading for computing performance that was once only the domain of dual processor systems.

Our test machine is configured with a Quadro P6000 high-end GPU and an Intel Xeon W-2155 processor, as well as 128 GB of RAM.  The storage included both 512 GB SSD storage and 1 TB HDD. The Fujitsu P27-8T UHD display provides a 4K 3840x2160 resolution. It is an excellent companion to the CELSIUS M770. The thin bezel is good for multiple-monitor configurations. The monitor swivels from landscape to portrait. It supports 100% sRGB color space and offers a wide viewing angle. In short, the high-end features are a nice match to the high-end performance of the CELSIUS M770.


The CELSIUS M770 supports two, new Quadro GV100 GPUs. Our system is configured with a Quadro P6000. The workstation also supports the Quadro P5000 graphics cards, among others.

It includes Intel Xeon W family processors from the Quad-core W-2102 up to the 10-core W-2155. We tested the latter. The operating system options include Windows 10 Pro for Workstations as well as Red Hat and SUSE versions of Linux.

Storage configurations include a multitude of SSD solutions including business critical SSD drives up to 1 TB in capacity with PCIe and SATA III interfaces. HDD storage options range from high-performance 10,000 rpm SAS drives to SATA III business critical drives. Altogether, the workstation offers seven drive bays and four of these offer cold-plug access from the workstation’s front panel.

Configuration options include a selection of optical drives. A selection of add-in cards for networking and wireless connectivity are available as well.

This workstation supports up to 256 GB of RAM. The motherboard has 8 DIMM slots supporting 2.666 MHz DDR4 memory modules. The test system is configured with 128 GB of memory. This RAM capacity matches nicely with the dual GPU configuration and the 10-core CPU for applications in simulation, big data analytics, and machine learning.

Naturally, this class of workstation sports ample amounts of connectivity. The CELSIUS M770 is loaded with USB connections which includes 2 USB Type-C connectors on the front panel. The back panel has an RJ-45 connection for networks, and it has audio in & out connections as well.

Last-but-not-least, the workstation has seven PCI Express 3.0 slots. Two of the PCI Express slots are full-length, x16 slots. Thanks to this, the CELSIUS M770 supports two ultra-high-end graphics cards like the Quadro GV100.  Full details on the system configuration can be found in the CELSIUS M770 data sheet.


Design Simplicity

The CELSIUS M770 stands out from the workstation crowd with its remarkable system design. The workstation is, for all practical purposes, cable-free. The Fujitsu engineering team essentially removed every possible cable in the system.

A simple latch-and-pull system has replaced cable connections throughout the system: from the power supply to the hard drives to the controller cards.  This effort from the CELSIUS M770’s design team makes the system simple to service. In fact, it is possible to remove nearly every internal component in less than one minute.

The workstation also has an efficient airflow design. It channels the cooling system into three sections which optimizes the airflow and cooling system. This in turns leads to a quiet workstation. The CELSIUS M770 is, in my opinion, completely silent unless either the CPU or GPU is being pushed to 100% utilization.

Not to be overlooked in a workstation that weighs approximately 18 kg / 40 lb. are the built-in handles of the CELSIUS M770. On the top of the workstation, both in the front and in the back, are handles and grips that allow you to grab and move the workstation comfortably. While this might seem like a small detail in the design, the result is that customers can move the workstation more easily and securely. This helps avoid accidents that might injure employees or damage the workstation.


This workstation delivers performance. The NVIDIA Quadro P6000 has been the professional GPU performance king for some time and has only recently been deposed by NVIDIA’s Quadro GV100. With this high-end graphics support, the workstation is a good choice for deep learning and blockchain applications. The graphics power also makes the CELSIUS M770 a high-performance VR workstation. In fact, the previous generation powers Autodesk’s VR Excellence Center in Munich, Germany.

The Intel Xeon W-2155 delivers peak speeds of 4.5 GHz which helps feed the Quadro P6000. The 10 cores, running at 3.30 GHz, drive up performance for applications in simulation, rendering, and special effects.


Viewperf 12.1

Viewperf, from the SPEC.org industry group, measures workstation performance using data sets from nine professional application areas. These include applications in 3D modeling and data visualization. 

Viewperf is designed to measure graphics workstation performance. The focus is on graphics. The values in the composite scores are measured in frames-per-second (FPS). The CELSIUS M770 has the fastest performance we have tested to-date. In our table, we compare the results to a reference workstation configuration.




Highly parallel applications in rendering, simulation, and video leverage both many-core CPUs and highly parallel-processing GPUs. One example is shown here with rendering results from Adobe Premier Pro CC 2018.

We ran rendering tests on three videos. Each video represents a typical, non-trivial rendering exercise. In these tests, performance is increased by the 10-core Intel processor. However, the largest performance gain is provided by the NVIDIA Quadro GPU.

We show the results of rendering times using GPU acceleration and without GPU acceleration. We normalize the rendering times to the actual video duration. This allows you to estimate how much time can be saved on your own projects.

Our CELSIUS M770 test configuration delivers high-performance results. In every case, the workstation renders our video examples in less than half of the time of the actual video duration, and in two of our tests, in less than one-third of the actual video duration.

When rendering without the GPU, the Intel Xeon’s 10 cores do an outstanding job. On the other hand, users benefit very much from applications that leverage both the GPU and the CPU. In our case, video rendering times can be three to six times faster by using the GPU.



Our Perspective

The CELSIUS M770 workstation gives users the latest computing technology. This single-processor workstation supports two ultra-high-end Quadro GPUs, 256 GB of RAM, and a very large storage capacity. This technology update and performance places it at the top of the list for performance workstations.

What makes the CELSIUS M770 stand out is the simplicity of the design. It has been unheard of, up to now, to tear-down a high-performance system in one minute. The speed and ease with which this workstation can be serviced is a benefit to users.
