Nvidia's DGX Spark costs 2.4x a Strix Halo mini-PC. it barely beats it on the number everyone checks

both give you ~128GB of unified memory for local AI, and their memory bandwidth is almost the same — 273 vs 256 GB/s. so the $2,700 gap buys… Aliteq Ravi Malhotra · Hardware Editor

Token generation speed on these unified-memory boxes is governed by memory bandwidth. The DGX Spark's GB10 runs LPDDR5X at 8533 MT/s for 273 GB/s; Strix Halo runs 8000 MT/s for 256 GB/s. That's a 7%…

The number everyone checks — and why it barely moves

The DGX Spark's real advantage isn't bandwidth, it's raw AI compute — roughly a petaflop from its Blackwell GPU, several times what Strix Halo's integrated Radeon musters. That doesn't help token…

Where the 2.4x actually goes: compute and CUDA
