Configuration and site considerations

The MI455X arrives as a liquid-cooled Helios rack, with delivery timing still ahead.

  • Plan for direct liquid cooling at rack scale.
  • AMD shares power data under NDA; confirm the site's power plan with the system builder.
  • Confirm the delivery schedule; shipments begin in the second half of 2026.

Prepare this system for a financing review

Document the configuration, the supplier and the deployment so the request can be assessed against the actual equipment.**

  • System configuration and quantity

  • Supplier and purchase order

    Or fleet details and ownership information for deployed servers.

  • Deployment site and colocation agreement

  • Power and cooling readiness

  • Customer contract or documented on-demand revenue

Discuss GPU financing

*Yield information: Current net and gross APYs are the staking yields reported by the USD.AI app at the displayed observation time. Projected gross APY is a forward-looking estimate and may rely on assumptions about loan deployment, borrower performance, reserve or escrow earnings, utilization and fees. Loan APRs describe loan interest rates and are distinct from staking APYs. Figures refresh periodically; a stale or unavailable source is identified beside the metric. No yield or projection is guaranteed. Actual performance may be lower, zero or negative. Withdrawals depend on the queue. Loan defaults, collateral losses, and smart contract or operational failures can cause losses.

**All financing subject to underwriting, eligibility and definitive documentation. Application submission begins a review. It does not establish a financing commitment. Calculator results and Compute IQ's sample deal are illustrative scenarios based on the inputs shown, not a financing offer or approval; the final loan amount depends on GPU condition and verification. Listing a system is not a statement of eligibility; equipment and transaction eligibility are reviewed individually.
