Core Viewpoint - The article discusses the advancements in chip technology, specifically the Maher 100 dual-chip system used in the new L9 model, highlighting its superior effective computing power compared to Nvidia's Thor U chip. Group 1: Chip Performance - The Maher 100 chip has a total computing power of 2560 TOPS, with each chip providing an effective computing power of 1280 TOPS, which is three times that of Nvidia's Thor U chip [1] - The effective computing power is defined as the actual performance achieved when running VLA large models, emphasizing the high utilization and low power consumption of the data flow architecture [1] - The new L9 model's dual Maher 100 chips provide an effective computing power that is 5-6 times greater than that of Thor U [1] Group 2: Industry Trends - The company anticipates that by 2025, the industry will enter an era of integrated self-developed algorithms and computing power, with the Maher 100 being the first step in this direction [1] - The article references a July 2025 report indicating that Nvidia's originally advertised 700 TOPS for the Thor chip is realistically closer to 500 TOPS after adjustments [1][2] Group 3: Precision and Performance - Higher TOPS leads to increased model throughput, which reduces inference latency and speeds up response times [2] - Fast response times require the use of low-precision inference models, which demand significant engineering capabilities [2] - The current VLA model from the company uses a mixed precision of INT8 and FP8 for inference, allowing the Thor U chip to achieve 700 TOPS [2][3] Group 4: Chip Specifications - The Thor platform supports various precision formats, with the following TOPS values: 700 TOPS for Thor U and 1000 TOPS for Thor X at FP8 precision, and 1400 TOPS for Thor U at FP4 precision [4][6] - The company plans to optimize towards FP4 precision in the future to achieve 1400 TOPS with the VLA model [6]
