All wired connectivity from a single isolated tile — Thunderbolt 6, PCIe 6.0, NVMe 3.0, USB4 Gen 5, and 2.5GbE — with Intel Need Technologies ensuring bandwidth is always allocated to what matters most.
Thunderbolt 6 represents a generational leap from Thunderbolt 5. Built on the USB4 v2 foundation, TB6 delivers 160 Gbps symmetric bandwidth — doubling the 80 Gbps of TB5 and increasing the bandwidth-boosted ceiling to 240 Gbps unidirectional when display-intensive downstream devices demand asymmetric allocation.
Four TB6 ports allow daisy-chaining and parallel tunnelling of multiple high-bandwidth protocols. Each port supports full backward compatibility with Thunderbolt 3, 4, 5, and USB4 v1.0 devices — a critical advantage for installed base adoption.
Bandwidth Boost is the game-changer: when an external display with iDP or DP 2.1 UHBR20 is connected, the I/O tile dynamically allocates up to 240 Gbps unidirectional to that port, ensuring zero display tearing or latency spikes even under saturated PCIe/storage load.
PCIe 6.0 introduces PAM4 (Pulse Amplitude Modulation 4-level) signalling and achieves 64 GT/s per lane — a full 2× bandwidth jump over PCIe 5.0. Within the I/O tile, PCIe 6.0 ×4 configurations deliver up to ~24 GB/s sequential throughput, unlocking the next generation of high-speed NVMe SSDs and memory-attached devices.
Role in the I/O ecosystem: PCIe 6.0 feeds both the NVMe subsystem (for ultra-fast storage) and high-bandwidth peripherals (external accelerators, media interfaces). A separate lane pool from the TB6 controller ensures that NVMe reads never starve due to competing TB6 traffic.
The Eventide I/O tile also reserves a portion of its PCIe 6.0 fabric for the iDP display protocol — a private, low-latency tunnel that bypasses contention with storage and general I/O, keeping frame rates locked to the display refresh rate even under peak system load.
Intel Need Technologies is a proprietary QoS (Quality-of-Service) framework built into the I/O Controller tile. When bandwidth becomes contested — all four TB6 ports active, simultaneous NVMe write, external GPU demand, and audio streaming — Need Technologies enforces a latency-critical priority stack that prevents any single workload from degrading user experience.
Frame-locked and preemptive. Any display refresh cycle gets guaranteed latency <100 μs.
Jitter-protected. Zero-dropout guarantee for USB Audio and Thunderbolt audio bridging.
Scheduled reads/writes. Preemptable only by Tiers 1–2, ensuring predictable I/O latency.
Best-effort allocation. Competing high-speed devices share remaining bandwidth fairly.
Background. Fills remaining capacity; preemptable at any time by higher tiers.
This hierarchical model ensures that real-time workloads never interfere with user perception. The Eventide PSM (Power & Security Management) tile works hand-in-hand with Need Technologies to monitor CPU demand and thermal state, dynamically throttling lower-priority I/O when the system approaches thermal limits.

Intel vPro Active Management Technology (AMT) extends security to the I/O layer. The PSM tile and I/O Controller communicate over a dedicated, encrypted channel, enabling out-of-band threat detection, remote diagnostics, and secure port management even when the main OS is offline.
