Lattice Semiconductor shares jump 4.5% after Nvidia CEO announces Vera Rubin chip entering full production and RTX Spark AI PC chip co-developed with MediaTek

Lattice Semiconductor (NASDAQ:LSCC) stock rose 4.5% in the afternoon session following Jensen Huang's GTC Taipei keynote announcement that Vera Rubin, Nvidia's successor to Blackwell, is entering full production. Vera Rubin delivers a 10× reduction in inference token cost (the computational step where an AI produces an answer) and requires 4× fewer GPUs to train the same models.

Nvidia also unveiled RTX Spark, an Arm-based AI PC chip co-developed with MediaTek, which integrates a Blackwell GPU and a Grace CPU on a single package with 128GB of unified memory and can run 120-billion-parameter AI models locally without cloud connectivity. RTX Spark launches later in the year on Windows PCs from Microsoft, Dell, HP, ASUS, Lenovo, and MSI.

The stock cooled to $151.31 after the initial move. The market volatility context: Lattice Semiconductor shares have had 28 moves greater than 5% over the last year, suggesting the market views today's news as meaningful but not a fundamental shift in the business outlook.
