- 27 июл.💻️ Nvidia quietly increases Jetson prices by up to 101% NVIDIA has raised prices across its Jetson modules and developer kits by up to 101%, following earlier product discontinuations linked to rising LPDDR4 memory costs. The largest increases affect the Jetson Nano module (from $99 to $199) and the Jetson AGX Orin 32GB module (from $899 to $1,799). The popular Jetson Orin Nano Super Developer Kit has also increased from $249 to $399. The new prices are reflected on NVIDIA's store and most retailers, though some backordered listings may still show the old pricing. NVIDIA has not provided an official explanation for the increases, but industry observers believe they are driven by rising DRAM memory costs and ongoing supply constraints. The company updated the pricing on its official website without an announcement, leaving it unclear whether the higher prices are a temporary response to market conditions or a permanent change to the Jetson product lineup. ⛓ More information... #news #nvidia0,23%
