  25-30%

####4.2 Market Share and Commercialization Progress

Based on public information:

• Kunlunxin’s2024 Revenue
  : Expected to exceed
  1 billion RMB
  [1]
• China Mobile Order
  : Exceeding
  1 billion RMB
  [1]
• Valuation Level
  : Approximately
  21 billion RMB
  [1]
• Listing Plan
  : Submit Hong Kong listing application in January2026 [1]

###5. Quantitative Comprehensive Evaluation Model

Comprehensive Competitiveness =0.4×Technical Performance +0.35×Ecosystem Maturity +0.25×Local Advantage

Kunlunxin P800 Comprehensive Score:
=0.4×(6.3/9.3×100)+0.35×(5.0/9.5×100)+0.25×(85/100×100)
≈27.1+18.4+21.3
≈66.8 points (Full Score:100)

NVIDIA A800 Comprehensive Score:
=0.4×100+0.35×100+0.25×50
≈40+35+12.5
≈87.5 points

###6. Key Conclusions and Investment Implications

####6.1 Summary of Technical Barriers

1. Hardware gap of approximately32%
   : Mainly reflected in IP core accumulation and advanced packaging capabilities
2. Software ecosystem gap of approximately47%
   : CUDA ecosystem is the biggest moat; Kunlunxin needs5-10 years to catch up
3. Process technology is basically the same
   :7nm process can already meet most inference needs

####6.2 Summary of Ecological Advantages

1. Policy dividend window period
   : The period2025-2030 is expected to be the golden age for domestic substitution
2. Cost advantage is obvious
   :25-30% TCO savings are attractive to price-sensitive customers
3. Few shortcomings in localized services
   : Unique advantages in sensitive fields such as government affairs and finance

####6.3 Quantitative Conclusions

Dimension	Kunlunxin P800	NVIDIA A800	Relative Competitiveness
Technical Performance	★★★☆☆	★★★★★	60%
Ecosystem Maturity	★★☆☆☆	★★★★★	53%
Local Advantage	★★★★★	★★☆☆☆	170%
Comprehensive Competitiveness	★★★☆☆	★★★★☆	76%

: Kunlunxin P800 already has commercial competitiveness in (reaching 70-80% of A800’s performance), but there is still a large gap in . Against the backdrop of domestic substitution, it has significant advantages in and . It is recommended to continue monitoring its software ecosystem construction progress and capital operation after listing [1][2].
