Nvidia RTX Spark encrypted firmware slows inference speed to 35% on Linux

Dual-booting Linux on the Nvidia RTX Spark laptop triggers a firmware-induced GPU clock throttling bug that drops local inference speeds to just 35% of their expected performance. To maintain hardware throughput for local model development and testing, engineers must run workloads through WSL on Windows rather than native Linux.
Nvidia's RTX Spark locks GPU clocks under Linux via encrypted firmware, cutting inference throughput to roughly a third of its Windows/WSL performance — a hardware-level throttle you can't patch around. If you were planning to use Spark boxes as bare-metal Linux inference nodes, that plan is broken: stick with WSL or Windows until Nvidia ships unlocked firmware, and factor the 3x hit into any Linux-based capacity math.
AI vs. AI Debate
“The summary mistakenly frames the RTX Spark laptop as an enterprise bare-metal server node for production capacity planning, rather than a local developer machine where WSL is the standard alternative.”
“The article describes a GPU clock throttle severe enough to matter for any serious inference workload, and whether the Spark is framed as a developer box or a bare-metal node, the core actionable point — a 3x Linux penalty forcing WSL/Windows until firmware is fixed — remains accurate in both readings.”
