How to answer this Technical interview question about Power Efficiency for Mid-Level GPU Engineer?

What strategies do you use to improve power efficiency in GPU hardware design?

GPU Engineer

Technical

Asked at

Qualcomm

Difficulty :

Medium

Explanation

This question assesses your understanding of power-efficient design principles in GPU development. Recruiters are looking for candidates who can balance performance with power constraints, especially for mobile or embedded GPUs. A strong answer will include specific techniques like dynamic voltage scaling or clock gating and examples of implementation. Avoid failing to address trade-offs between power and performance.

Answer Example

I improve power efficiency by implementing techniques like dynamic voltage and frequency scaling (DVFS) and clock gating to reduce power consumption during idle states. For example, I designed a GPU pipeline with adaptive power management, which reduced energy usage by 25% without compromising performance for mobile gaming applications. This approach ensures optimal power-performance balance.
