Fujitsu CELSIUS H710 WXP11DE

          The Fujitsu CELSIUS H710 WXP11DE bids high workstation performance in a "small" 15.6 inch laptop. The mobile workstation is equipped with a second generation (Sandy-Bridge) Intel quad core processor and a high performance Nvidia graphics. The matt display, with a screen diagonal of 15.6 inches, has a resolution of 1920x1080 pixels (Full HD). The dedicated Quadro 1000M graphics card, which is equipped with 96 cores, is optimized for computer aided design, digital content creation, geographic information systems, architecture, engineering, construction and medical imaging.

         The laptop can connect to the Internet almost everywhere via WLAN, Bluetooth and UMTS. The Celsius H710 has extended security functions, such as a fingerprint sensor or CompuTrace, which protect the data on the device against theft or should the notebook be stolen.

The workstation's feature list sounds good: First there is the Core i7-2820QM quad-core CPU with 2.3 GHz and an NVIDIA Quadro 1000M graphics with 2048 MB of video memory. A 265 GB SSD (solid state drive) is used as the data memory in our H710. The DDR3 RAM that is equipped with 8 GBs in this model can be extended up to 16 GB.

Performance

A Core i7-2820QM from Intel is used in Fujitsu's workstation, Celsius H710. This CPU is a quad core processor and is based on the Sandy Bridge architecture. The processor has four CPU cores and can process up to eight threads at the same time thanks to Hyper Threading support. The Core i7-2820QM has a base clock of 2.3 GHz. Single CPU cores can occasionally be overclocked automatically up to 3.4 GHz by the Turbo Boost technology. The processor has a 3 MB level 3 cache and is manufactured in 32 nm technology.

An Nvidia graphics card, model NVIDIA Quadro 1000M is built into the system for the graphics. The graphics card has its own 2048 MB video memory. The GPU runs with a clock of 700 MHz. While the competition from Dell, HP and Lenovo partly also rely on the stronger Quadro 2000M, Fujitsu currently doesn't have an option for the stronger GPU.

Intel has also incorporated a DirectX 10 capable Intel HD Graphics 3000 graphics card and the memory controller into the Sandy Bridge processor. The CPU's HD graphics isn't used in the Celsius H710. The user can't switch between the integrated and dedicated graphics in either the BIOS or in Windows via the GPU driver. The Celsius H710 laptop uses the Quadro 1000M graphics only.

The CPU's maximum clock rate of 3.4 GHz only remained available up to a DIE temperature of about 80 degrees Celsius in the stress test. The Turbo Mode wasn't completely exploited beyond that. The CPU clock settled between 2.3 and 2.5 GHz. The base clock remained stable at a minimum of 2.5 GHz in our hour-long, simulated stress test - a couple of computing intensive programs ran simultaneously for this (Prime95, Furmark). Thus, Turbo Boost could even keep the rate above the base clock in this case.
