DGX Spark drops back to $3,999.99, Mac Studio M4 Max 128GB falls under $5,000
The number that matters today is the NVIDIA DGX Spark listing on Amazon, which our refresh confirmed at $3,999.99. That is down from $4,799.99 on the previous history entry, and it puts the 128 GB box back into a different bracket for anyone who wants one compact machine that can hold larger quantized models without splitting them across cards. If you have been weighing it against a Framework Desktop 128GB or the current Mac Studio 128GB comparison, this is the first move in a while that actually changes the conversation.
Apple’s high-memory configurations moved too, but here the action is on tracked eBay listings rather than a vendor-wide price change. We confirmed an Apple Mac Studio M4 Max 128GB listing at $4,985, down from $6,599.99, and an Apple Mac mini M4 Pro 64GB listing at $2,999.99, the lowest price we have recorded for that config. If you want a smaller Metal box and do not need DGX Spark capacity, compare the current Mac Studio 128GB page against the Mac mini 64GB option before assuming the Studio premium is still as wide as it looked yesterday.
There is also a newly tracked RTX 5090 eBay listing at $2,350. Treat that one as a marketplace deal, not a new normal street price. We did not see a broader restock event on the supply-constrained boxes, and the replacement RTX PRO 6000 Blackwell eBay listing simply kept that card available instead of signaling a wider availability shift.
