NVIDIA's $2,899 RTX Spark Just Made Its OWN $4,699 DGX Spark Pointless!
NVIDIA RTX Spark performance tests reveal a major shift in local AI hardware, making the expensive DGX Spark model harder to justify.
We compare these two machines to see if the RTX Spark can handle the same workloads as its pricier counterpart. This breakdown focuses on the capabilities and limitations of each device, helping you decide which hardware fits your specific AI project needs without overspending on features you might not utilize.
By analyzing the price difference and technical output, we provide a clear look at where the RTX Spark excels and where the DGX Spark still holds an advantage in professional environments. Understanding these local AI hardware trade-offs is essential for developers building out their own compute clusters or workstation setups.
Spotlight Moments:
⚡Project Digits debuted at CES 2025 aimed at $3,000, shipped October 15 2025 at $3,999, then jumped to $4,699 on February 27 2026 with zero hardware changes
⚡Memory bandwidth measures 273 GB/s, not the 300 still quoted on early marketing slides, landing around 38 tokens per second on decode
Prefill runs five times faster than AMD while answering only 13 percent quicker, which is the whole purchasing argument in one line
⚡RTX Spark splits into N1 and N1X tiers, and the $1,799 figure belongs to N1 laptops, not DGX Spark silicon
⚡ASUS Ascent GX10 and MSI EdgeXpert run the identical GB10 chip from $2,999, though with 1TB storage against the Founders Edition's 4TB
⚡Dual node clustering moves a 120B model from roughly 59 to 76 tokens per second, nowhere near double for double the price
⚡DRAM contract prices climbed 90 to 98 percent quarter over quarter in Q1 2026, pushing this entire category upward.
