China's Lisuan Tech unveils homegrown 6nm GPUs capable of 4K gaming at 70+ FPS and matching RTX 4060 performance in benchmarks
China is making significant strides toward technological self-reliance with the launch of Lisuan Tech’s first consumer and professional graphics cards, the 7G106 and 7G105. These GPUs, built on TSMC’s 6nm N6 process, feature the company’s proprietary TrueGPU architecture and aim to challenge mid-range offerings from industry giants like Nvidia and AMD. While the initial focus is on gaming, the chips are positioned as versatile accelerators for AI, cloud rendering, and metaverse applications, reflecting broader ambitions in the semiconductor sector. The 7G106, designed for consumers, boasts 12 GB of GDDR6 memory across a 192-bit bus, 192 texture units, 96 raster operations units (ROPs), and an FP32 throughput of up to 24 teraflops (TFLOPs). It supports modern APIs such as DirectX 12 (excluding ray tracing), Vulkan 1.3, OpenGL 4.6, and OpenCL 3.0, along with four DisplayPort 1.4 outputs featuring Display Stream Compression (DSC) 1.2b for 8K60 resolution. The card’s single 8-pin PCIe power connector suggests a maximum power draw of 225W. The professional 7G105 variant doubles the memory to 24 GB with error-correcting code (ECC) support, offering a 192 GB/s pixel fill rate and 384 GB/s texture fill rate, while maintaining the same 24 TFLOP/s compute performance. Both models support hardware-accelerated AV1 and HEVC decoding up to 8K60 and encoding at 8K30 for HEVC and 4K30 for AV1. They also enable up to 16 virtual GPUs via SR-IOV technology, catering to enterprise and AI workloads. What distinguishes Lisuan from earlier Chinese GPU efforts is its claim of developing the TrueGPU architecture entirely in-house, including the instruction set, compute cores, and software stack. The design incorporates features like “intelligent multitasking” with 48 concurrent tasks, out-of-order triangle rendering to improve efficiency by 50% in specific scenarios, and dual FP32/INT32 instruction execution. A proprietary matrix memory layout is said to enhance memory efficiency by 40%, while dynamic load balancing optimizes task distribution across cores in real time. Lisuan also highlights its NRSS rendering quality optimization system, which it compares to Nvidia’s DLSS and AMD’s FSR. Benchmark results show mixed but promising performance. In synthetic tests, the 7G106 scored 26,800 points in 3DMark Fire Strike and 2,256 in Steel Nomad, aligning closely with Nvidia’s RTX 4060. Geekbench 6 OpenCL results placed it slightly ahead of the RTX 4060 by about 10%. Gaming demos further underscored its potential, with titles like Black Myth: Wukong and Wuchang: Fallen Feathers achieving over 70 FPS at 4K High settings, while Shadow of the Tomb Raider exceeded 80 FPS under similar conditions. These results, particularly for high-profile games, suggest stability and readiness despite the architecture’s early stage. The 7G105 targets AI and professional markets, supporting SR-IOV virtualization for up to 16 containers. Lisuan emphasizes its suitability for cloud gaming, digital twins, virtual reality, and robotics, citing compatibility with large AI models like DeepSeek and Wenshengtu. This positions the chip as a competitor to Nvidia’s A100 and AMD’s Radeon Instinct series. Lisuan’s entry marks a pivotal moment in China’s GPU development. Previous domestic efforts, such as Zhaoxin’s integrated solutions and Moore Threads’ early discrete GPUs, faced challenges in gaining traction. The 7G106 and 7G105, however, represent a bold push to close the gap with global leaders. If independent testing validates their claims of architectural autonomy and performance parity, this could signal the first time a Chinese firm competes directly with Nvidia and AMD in discrete GPU markets. Mass production of the 7G106 and 7G105 is slated to begin in September 2025, following sampling in August. Pricing and final clock speeds remain unannounced, but the cards’ domestic focus may appeal to Chinese users navigating rising costs and export restrictions. As the global AI and gaming industries intensify, Lisuan’s progress underscores China’s growing influence in semiconductor innovation.
