Four Intel Arc Pro B70s. 128GB of VRAM total. $4,000. One RTX PRO 6000 Blackwell. 96GB. $10,000. The pitch writes itself: gang up cheap cards, beat the expensive one, pocket $6,000. And on raw memory it's true — four B70s hold more than the single Blackwell. Here's what the price comparison leaves out. Four cards means the model gets split across four of them, and every token crosses PCIe to move between cards. The Blackwell is one pool — no splitting, no PCIe tax. Same reason a 128GB cluster and 128GB unified aren't the same 128GB. So the real question isn't "which has more VRAM for less." It's what you're running. Models that fit on one B70's 32GB? The cluster's a steal. Models that need to span all four? You're now paying in latency what you saved in cash. $4,000 of Intel is the right call for a lot of workloads. Just not because it "beats" a $10k card — because it's a different shape of machine for a different job.
