Technical Specifications at a Glance

10-Core CPU Architecture: Clock Speeds & Dual SME2 Units

The CPU pipeline utilizes a 10-core dynamic architecture split into 6 Super Cores and 4 Large Cores, delivering a massive 60% peak performance increase over the previous generation:

• 2× C1-Ultra Cores @ 4.35 GHz (Super Cores for single-threaded bursts)

• 4× C1-Premium Cores @ 3.68 GHz (Super Cores for sustained high load)

• 4× C1-Pro Cores @ 3.15 GHz (Large Cores for power efficiency)

To accelerate heavy mathematical matrices and vector calculations, the CPU integrates Dual SME2 (Scalable Matrix Extension) acceleration units. A unified 60MB total cache minimizes execution delays during heavy multitasking.

G2-Ultra NX GPU: Desktop-Class Ray Tracing

Graphics capabilities see a dramatic leap forward thanks to the 16-core G2-Ultra NX GPU:

• +85% Peak Performance: Smooth execution of high-framerate titles.

• -64% Power Consumption: Extended gaming endurance under identical workload demands.

• +182% Ray Tracing Boost: Hardware-accelerated dynamic shadows, reflections, and global illumination.

• Native AI Frame Interpolation: Real-time super-resolution built straight into the GPU pipeline.

Next-Gen Memory Architecture: Outperforming Apple’s Latency

The XRING O3 is the industry’s first mobile processor designed to support LPDDR6 RAM, driving substantial improvements across bandwidth, timing, and latency:

• 113.8 GB/s Bandwidth: Powered by a 4×24-bit memory bus width running at 10,667 Mbps (a 48% bandwidth uplift).

• 82ns Latency: Record-low memory access latency, surpassing Apple’s A19 Pro metrics.

• 54% Lower Latency: Substantial latency optimization over the XRING O1.

• Xuanjie Unified Integration Protocol: Reduces protocol conversion overhead by up to 75%. Physical interconnect paths are shortened via high-layer metal traces and intelligent memory prefetching.
