Quanta / QCT vs Wiwynn for NVIDIA AI servers.
Side by side from our vendor index: what each firm actually designs, which NVIDIA platforms it ships, and the identity facts that shape a procurement decision. Sources and full detail live on each profile.
Quanta / QCT
Quanta is the original hyperscale ODM and QCT is its direct-sale arm. It designs boards and rack systems for the largest clouds, and the same engineering is available over the counter through QCT for buyers who can self-support.
- Designs its own server boards and compute trays; builds complete GB200 NVL72 racks from 18x QuantaGrid D75B-1U trays
- Markets solutions validated at L10 (system), L11 (rack) and L12 (cluster) integration levels
- Dual-track model: custom ODM designs for hyperscalers (Meta, Google, Microsoft, AWS) plus NVIDIA reference systems sold under the QCT brand to enterprises and telcos
- Own rack-scale liquid-cooling line (QoolRack) removing up to 75kW of heat per rack, cutting cooling power up to 66.8% vs air
Wiwynn
Wistron's hyperscale spinoff, focused purely on cloud datacenter systems. Wiwynn designs rack-scale liquid-cooled NVL systems for hyperscalers and has been moving up the stack into full rack integration. Not a channel vendor: it sells at datacenter scale.
- ODM-direct model: end-to-end from board-level components through complete L11 rack integration; OCP Platinum member
- One of four ODMs (with Foxconn, Quanta, Wistron) holding NVIDIA Certified Systems status as main suppliers of GB200/GB300 full cabinets
- Among the first in line for GB300 NVL72 and Vera Rubin NVL72 readiness, with fully liquid-cooled fan-less rack designs
- Own rack cooling engineering: Aqualoop ORv3 liquid cooling with blind-mate tubes, UMS100 cooling management integrated with Auras CDUs
