Tianshu Zhixin has revealed that Big Island, China’s first 7-nanometer GPU, is about to enter mass production and commercial delivery. The company claims that the GPU is capable of offering nearly twice the performance of mainstream manufacturers’ products at a lower power consumption, which seems impressive since it only uses half the chip area of similar products. Big Island features a 32 GB HBM2 memory configuration and a peak FP32 rate of 37 TFLOPS.
