Authored by: Amit Sharma, Teodor-Dumitru Ene, Kishor Kunal, Mingjie Liu, Zafar Hasan and Haoxing Ren (NVIDIA Corporation)
This paper presents a comparative analysis of total cost of ownership (TCO) and performance between domain-adapted large language models (LLMs) and state-of-the-art (SoTA) LLMs, with a particular emphasis on tasks related to coding assistance for chip design. We assess the efficacy of a domain-adaptive LLM, ChipNeMo, against Claude 3 Opus and ChatGPT-4 Turbo, providing critical insights for economically viable and performance-efficient AI solutions in chip design.

ChipNeMo Training Process: Domain Adaptation for ASIC Design
ChipNeMo's superior performance stems from its specialized training methodology, combining Domain Adaptive Pre-training (DAPT) and Supervised Fine-Tuning (SFT). This approach tailors the foundational LLaMA2 model to the intricate language and context of ASIC design, utilizing NVIDIA's internal chip design documentation and proprietary Tcl codes.

The DAPT phase, processing 120 million tokens from industry-standard CAD tool documentation and code snippets, required 100 GPU hours. The subsequent SFT phase, focused on EDA tool-specific tasks using 5 million tokens of proprietary Tcl codes, required an additional 4 GPU hours. This rigorous adaptation ensures ChipNeMo's proficiency in generating accurate and contextually relevant code snippets for complex chip design tasks.
Comparative Performance: ChipNeMo vs. SoTA LLMs
Our evaluation benchmark, featuring medium to high complexity ASIC design coding tasks, demonstrates ChipNeMo's significant edge over general-purpose LLMs like Claude 3 Opus and ChatGPT-4 Turbo.
| Metric | ChipNeMo-70B | Claude 3 Opus | ChatGPT-4 Turbo |
|---|---|---|---|
| Accuracy (Higher is better) | 79% | 68% | 70% |
| Hallucination (Lower is better) | 13% | 11% | 2% |
| Inference Speed (sec/task, Lower is better) | 0.2 | 0.4 | 0.3 |
79% Accuracy
ChipNeMo achieved the highest accuracy in avoiding syntax and logical errors in ASIC design tasks, affirming the benefits of domain-specific training.
While ChatGPT-4 Turbo showed the lowest hallucination rate, ChipNeMo's overall balance of high accuracy and competitive inference speed makes it the most effective solution for specialized chip design applications.
Total Cost of Ownership (TCO) Analysis
The economic viability of domain-adapted LLMs is clearly demonstrated through a comprehensive TCO analysis, considering training, inference, and operational costs. ChipNeMo offers a compelling value proposition, particularly as deployment scales.
| Item | ChipNeMo Total Cost ($) | ChatGPT-4 Turbo Total Cost ($) | Claude 3 Opus Total Cost ($) |
|---|---|---|---|
| Lower Workload (0.3M Queries) | $508 | $9000 | $12000 |
| Average Workload (0.6M Queries) | $808 | $18000 | $24000 |
| Higher Workload (1.1M Queries) | $1208 | $30000 | $40000 |
Our analysis reveals that ChipNeMo-70B TCO is significantly lower—approximately 18-25 times less than ChatGPT-4 Turbo and 24-33 times less than Claude 3 (based on workload). This translates to potential cost savings of millions of dollars for companies with extensive LLM usage in coding and software development tasks.
Real-World Impact: Massive Cost Savings
As the deployment scale expands, domain-adapted LLMs demonstrate even more pronounced cost benefits. The initial investment in domain-specific training is amortized over a larger number of inference tasks, leading to a lower per-task cost.
Organizations with substantial coding needs can achieve 90-95% cost reductions compared to larger SOTA LLMs, similar to the 95% TCO reduction achieved by a global manufacturer adopting managed services. This underscores the transformative economic potential of specialized AI models in the chip design industry.
