Core Viewpoint - Longxin Technology's first GPGPU chip, the 9A1000, is nearing completion with plans for tape-out in Q3 2023, marking a significant milestone for the company, which has primarily focused on processors until now [1][3]. Group 1: Product Development - The 9A1000 is positioned as an entry-level graphics card supporting AI acceleration, distinguishing it from other Chinese graphics cards like the Lisuan G100, which is said to compete with the GeForce RTX 4060 [1]. - Specific specifications of the 9A1000 remain undisclosed, but it is suggested to have performance similar to the Radeon RX 550 released eight years ago [3]. - The chip supports PCIe 4.0 and is compatible with 128-bit LPDDR4X high-speed memory, featuring eight computing clusters and advanced internal architecture [3][4]. Group 2: Performance Specifications - The 9A1000 boasts a pixel fill rate of 16 GP/s, a texture fill rate of 32 GT/s, and floating-point performance of 1 TFLOPS (FP32) and 64 GFLOPS (FP64), with INT8 performance reaching 32 TFLOPS [4]. - Recent updates indicate a 20% reduction in the area of stream processors, a 25% increase in operating frequency, and a 70% optimization in power consumption under light load [4]. - The 9A1000 is reported to be four times faster than the integrated graphics of the 2K3000 processor, with AI computing capabilities of up to 40 TOPS, slightly below AMD's Ryzen AI Max+ [5]. Group 3: Future Developments - Longxin is also developing the 9A2000, which is expected to be ten times faster than the 9A1000 and comparable to the GeForce RTX 2080 [5]. - Plans for the 9A3000, a successor to the 9A2000, are in place, although specific specifications are currently unclear [5].
