Headline Targets

These are design targets until benchmarked:

Area	Design target
TCP/UDP latency	Up to 10-45% lower latency
Effective CPU-AI memory bandwidth	3-18% higher
Sustained usable CPU-core performance	2-12% higher
Scheduler jitter/migration	Near-zero on hot AI paths

Caveats

XAI OS cannot exceed physical silicon limits. It cannot make DRAM, LPDDR, cache fabric, or CPU cores faster than the hardware.

The design targets depend on removing avoidable overhead: thread migration, context switching, page faults after warmup, generic socket buffers, background kernel work, duplicate model copies, bad NUMA placement, interrupt noise, and shared-resource contention.

ARM SoC Targets

ARM/NVIDIA N1X-compatible targets focus on cluster placement, LPDDR/unified memory behavior, SMMU protection, and keeping CPU-only AI workers on the intended cores.

Intel Desktop Targets

Intel Desktop targets focus on P-core/E-core placement, low-latency NIC behavior, DDR bandwidth, NVMe, and sustained frequency under build/test load.

Intel Xeon Targets

Intel Xeon targets focus on NUMA locality, many memory channels, server NIC queues, multi-queue NVMe, many AI Cells, and memory-bandwidth admission control.

Platform Target Table

Platform	TCP/UDP latency design target	Effective CPU-only AI bandwidth design target	Sustained core design target	Primary caveat
ARM/NVIDIA N1X-compatible	15-35% lower	8-18% higher	5-12% higher	Firmware and LPDDR behavior may limit control
Intel Desktop	20-45% lower	5-12% higher	4-10% higher	Limited memory channels and SMT/P-core/E-core policy matter
Intel Xeon	10-30% lower	3-10% higher	2-8% higher	Tuned NUMA Linux may already be strong

QEMU on macOS is excluded from performance claims.

Claim Boundary

XAI OS should only claim measured improvements for CPU-only embedded app agents under documented conditions. Broad claims that XAI OS beats Linux/BSD in general are not valid.
