China’s first 7nm graphics card launches


The Big Island graphics unit, developed by Tianshu Zhixin, offers features in the form of 24 billion transistors, 7nm manufacturing process, 32GB HBM2 memory, 1.2TB / s bandwidth.

China, which is under a heavy embargo by the USA, is still working with all its might to be independent on the chip side. Besides SMIC, which will start 28nm production by purchasing used production lines, Tianshu Zhixin is also taking an important step.

What does the Big Island graphics unit offer?

Chinese startup Tianshu Zhixin is one of the country’s major chips brands. He has been working on chip design for a long time and is taking his first step into the graphics market with a remarkable unit, at least on paper.

The graphics unit named Big Island has the feature of being the first 7nm process graphics chip of China and therefore the enterprise. Big Island, which has a focus, referred to as GPGPU for general operations, will enter into an intense competition.

The graphics unit, designed in 7nm process, contains 24 billion transistors and offers 32GB of HBM2 memory and 1.2TB / s bandwidth. It is stated that the unit, which focuses on a single precision floating point, offers 147 TFLOPS INT16 performance. TDP value is 300W. Since it is not covered by an embargo yet, it has the production done by TSMC.

For comparison, the Nvidia A100 accelerator has 54 billion transistors, 400W TDP, 80GB HBM2, 1.6TB / s bandwidth, 312TFLOPS INT16 performance. AMD Instinct 100 accelerator offers values such as 50 billion transistors, 1.2TB / s bandwidth, 92.3TFLOPS INT16 performance, 300W TDP.

The most important support for Tianshu Zhixin will undoubtedly be China. The products that will be provided to the servers of huge companies such as Alibaba will bring the Big Island graphics unit to an important place in the competition.
