NVIDIA RTX Spark
No editorial image yet — generic vendor mark shown. Credentials in spec table below.
The NVIDIA RTX Spark is a consumer PC SoC (Arm CPU + Blackwell GPU, co-developed with MediaTek) with up to 128GB of unified LPDDR5X memory shared between CPU and GPU. NVIDIA states it can run ~120B-parameter LLMs at up to 1M-token context. It ships inside OEM systems (laptops and compact desktops from ASUS, Dell, HP, Lenovo, Microsoft Surface, and MSI) in Fall 2026. As of mid-2026 NVIDIA has published no official pricing or memory-bandwidth figure for RTX Spark; press analyst estimates (~$1,800-$2,900) and a ~300 GB/s bandwidth figure are unofficial and unverified. Note: RTX Spark (consumer Windows SoC) is a different product from the DGX Spark (GB10 Ubuntu AI appliance).
Sub-scores sum to 230 / 1000. Headline = 230 × 0.70 (Estimated-confidence discount) = 161. This is an algorithmic performance-tier score — distinct from, and often lower than, the editorial “Our verdict” below, which weighs value and real-world fit (especially for hardware we haven’t measured yet). How scoring works →
Insufficient data — VRAM 0GB, bandwidth ? GB/s.
Plain-English: Doesn't fit modern chat models usefully — vision models won't fit.
