On April 3, 2025, Longxin Zhongke (688047.SH) officially announced on its WeChat public account that the Longxin 2K3000 (3B6000M) has successfully completed tape-out, achieving preliminary functionality and performance assessments, with all indicators meeting expectations. The Longxin 2K3000 and Longxin 3B6000M are different packaging versions based on the same silicon wafer, targeting the industrial control application field and mobile terminal field, respectively.
Longxin Zhongke introduced that this chip integrates 8 LA364E processor cores, achieving a measured SPEC CPU 2006 Base single-core fixed-point score of 30 points at a frequency of 2.5GHz.
The chip integrates the second-generation self-developed GPGPU core LG200, which has doubled the graphics performance compared to the first-generation GPU core LG100 integrated with Longxin 2K2000.
In addition to graphics acceleration, LG200 also supports general-purpose computing acceleration and AI acceleration, with a peak single-precision floating-point performance of 256 GFLOPS and an 8-bit fixed-point peak performance of 8 TOPS. Currently, the OpenCL computing framework and related AI acceleration software have completed preliminary testing, and related supporting software is being improved.
Regarding the successful tape-out of the 2K3000 (3B6000M), Longxin Zhongke specifically emphasized two points:
First, it marks that Longxin Zhongke has systematically mastered the key core technologies for general-purpose processors, graphics processors, AI processors, and their underlying software design after more than 20 years of accumulation. The development of Longxin processors has entered a new era of vigorously developing AI processors while consolidating general-purpose and graphics processors, taking a new step towards building a self-sufficient information technology system.
Second, it signifies that Longxin’s general-purpose CPU has formed a complete series of products across desktop, server, and terminal lines, capable of providing high-performance and cost-effective CPU chip products for different fields.
It is noteworthy that today, Longxin Zhongke’s stock price also saw an increase. As of today (April 3), the closing price of Longxin Zhongke was 129.75 yuan/share, up 3.75 yuan, with an increase of 2.98%. Based on a total share capital of 401 million, Longxin’s market value increased by approximately 1.5 billion yuan today.
