RESERVED B300

NVIDIA B300 288GB (Blackwell Ultra)

The B300 is the Blackwell Ultra flagship — 288GB of HBM3e and a step-change in FP4 inference throughput over B200. Allocation flows to frontier labs first; reserved commitments are the realistic path to 2026–2027 capacity outside direct NVIDIA channels.

Partner Network

AGGREGATED ACROSS
LEADING NEOCLOUDS

Compute Exchange aggregates reserved capacity from a verified network of leading AI-native cloud providers and hyperscalers. All partners undergo identity, capacity, SLA, and operational verification before quotes surface on the network.

You receive a normalized comparison across providers in a single quote response — rather than evaluating each neocloud's contract structure, billing model, and SLA terms in isolation.

WHY RESERVE

RESERVED B300
VS ON-DEMAND

B300 allocation is spoken for well before racks ship, and on-demand availability will be effectively nonexistent through 2027. Reserved commitments made now are how capacity outside the hyperscalers actually gets secured.

Frequently Asked Questions

RESERVED B300
KEY QUESTIONS

How constrained is B300 supply for reservations?+
Severely, through at least 2027. Blackwell Ultra allocation flows to hyperscalers and frontier labs first, and partner-network supply arrives in phased deliveries. Reserved commitments of 6 months and longer are how providers prioritize the allocation they do receive — on-demand B300 is not a realistic planning assumption.
What terms can I reserve B300 capacity for?+
Six, 12, 24, and 36-month terms. Shorter commits are generally not quoted while the part is allocation-constrained. Phased delivery schedules — capacity landing in tranches as racks are commissioned — are common for larger commitments and can be structured into the quote.
How does B300 compare to B200 for reservation planning?+
B300 carries 288GB of HBM3e versus 192GB on B200 and a significant step up in FP4 inference throughput. For inference fleets, the memory headroom changes batch economics; for training, the uplift is more incremental. B200 reservations quote faster and provision sooner — the tradeoff is locking last-generation silicon on a multi-year term.
