NVIDIA DGX Spark 64GB Review: The $4,999 On-Ramp to Local AI Supercomputing

NVIDIA cut the price of local AI supercomputing with the 64GB DGX Spark at $4,999. We test whether the cheaper box is a real on-ramp for developers or a memory-capped push toward the pricier 128GB model and two-box clustering.

Nvidia RTX Spark Laptops Go On Sale: 1 Petaflop of Local AI, Yet CPU Limits Persist

RTX Spark mini desktop designs from six partner brands

Nvidia’s RTX Spark laptops from ASUS, Dell, HP, Lenovo, Microsoft and MSI now ship from $2,399, bringing 1 petaflop of local AI compute and 128GB unified memory to thin Windows PCs. Our deep review weighs the unified-memory breakthrough against CPU-limited gaming, thermal throttling, Arm app gaps and a $2,399 floor that buys capability most buyers will not use.

Intel GPU D-Series: 480GB of Air-Cooled LPDDR5X Rewrites Inference Economics

Intel’s GPU D-Series packs 480GB of LPDDR5X and 1.3 petaflops of FP8 into a 350W air-cooled PCIe card, betting that inference economics reward memory capacity over bandwidth. We decode the specs, the prefill-versus-decode trade-off and the software gap Intel still has to close.

Samsung zNAND-O Wants to Run LLMs on Your Laptop — But Edge-AI Storage Has a Long Way to Go

At the Global Storage Innovation Forum in Shenzhen, Samsung stacked the compact 256 TB BM1773 QLC SSD, the PCIe 6.0 PM1763, the industry’s first 400-plus-layer V10 NAND, and the TSV-stacked zNAND-O on one stage. The datacenter hardware is real; the on-device AI promise is still a concept looking for an ecosystem.

The 40,000-Hour Witness: SanDisk’s CZ53C and the Quiet Arms Race to Record Your Car While You Sleep

The CZ53C is a three-gram USB-C stick that SanDisk launched in China in October 2026, purpose-built to live in a car’s data port and record dashcam and Sentry-mode parking video around the clock — its 1TB model rated for up to 40,000 hours of continuous loop recording.
