Published by INIBOX Matches, the official store for Pinecone Matches INIBOX ASIC miners. This architecture specification documents the Pinecone R1X Pro Gen III XMR Edition, the flagship third generation of our purpose-built RandomX miner for Monero (XMR).
1. Product Overview
The Pinecone R1X Pro Gen III is the flagship third-generation RandomX ASIC miner from Pinecone Technologies. This model represents a breakthrough in silicon design, process technology, and system-level integration. The Pro Gen III is not merely an incremental upgrade. It is a complete re-architecture of the compute, memory, and power delivery subsystems to achieve an unprecedented 4.0 MH/s hashrate.
The Pro Gen III introduces a multi-die chiplet architecture, advanced 3nm-class process technology, and a proprietary high-bandwidth interposer that connects compute and memory dies with ultra-low latency. This allows the system to scale beyond the thermal and memory bandwidth limitations of previous generations.
Competitive Positioning: Against the Bitmain Antminer X9 (1.0 MH/s at 2,472 W), the R1X Pro Gen III delivers 4x the hashrate while consuming only about 1.6x the power. This results in an efficiency advantage of approximately 2.6x on a per-hash basis, positioning the Pro Gen III as the highest-density RandomX miner available for professional fleet deployment.
2. Core Architecture
2.1 Compute Subsystem
| Component | Specification |
|---|---|
| Chip Architecture | Multi-die chiplet architecture: 4 compute chiplets + 1 central memory controller die on an active silicon interposer |
| Process Node | 3nm-class (N3E equivalent) for compute chiplets; mature 12nm for interposer and I/O die |
| Core Design | Third-generation RandomX core with dual-issue superscalar pipelines, branch prediction units, and dedicated dataset prefetch engines per core cluster |
| Instruction Set | Full native RandomX VM support with hardware acceleration for AES-encrypted memory operations and floating-point transcendental functions. Pro Gen III adds speculative execution support for RandomX's conditional branches. |
| Thread Parallelism | 32 hardware threads across 4 chiplets (8 threads per chiplet), each with dedicated scratchpad and L1/L2 cache |
| Sustained Output | Rated for 24/7 sustained load with stable 4.0 MH/s output (tolerance +/- 2%, tighter than previous generations) |
The Pro Gen III architecture distributes the RandomX workload across four identical compute chiplets. Each chiplet processes a portion of the total threads, and the central memory controller die arbitrates access to the shared 4 GiB dataset. This distributed approach allows for linear scaling of hashrate with chiplet count, avoiding the diminishing returns seen in monolithic designs.
2.2 Memory Subsystem
| Component | Specification |
|---|---|
| On-Chip Cache | Massive on-die cache per chiplet: 32 KiB L1, 1 MiB L2, and 4 MiB L3 per thread cluster (effectively 128 MiB total L3 across all chiplets) |
| External Memory | Dedicated 4 GiB GDDR6 memory module soldered to the interposer, optimized for RandomX's random read-only dataset with 256-bit data bus |
| Memory Bandwidth | 512 GB/s effective bandwidth across the interposer, a 3x increase over Gen II |
| Scratchpad | 2 MiB high-speed scratchpad per thread (unchanged capacity, but now with single-cycle access latency) |
| Cache/DRAM Hierarchy | Fully unified memory hierarchy with a global 512 MiB L4 cache on the interposer, sitting between the chiplets and the GDDR6 dataset, effectively reducing average dataset access latency by 40% |
The memory subsystem is the single most important differentiator of the Pro Gen III. By placing the dataset memory physically closer to the compute chiplets via the silicon interposer and adding a large L4 cache, the Pro Gen III virtually eliminates the memory bottleneck that has historically limited RandomX hashrate. The GDDR6 module provides the raw bandwidth, while the L4 cache absorbs the most frequently accessed dataset pages.
2.3 Power Architecture
| Component | Specification |
|---|---|
| Typical Power Draw | 3,800 W (at 220V) |
| Power Efficiency | 0.95 W per kH (950 W per MH) |
| Input Voltage | 220~277V AC (with a dedicated 277V high-efficiency mode) |
| Power Supply | Dual-redundant enterprise-grade PSUs (2 x 2,000 W, hot-swappable, 96% peak efficiency) |
| Power Factor | Active PFC with > 0.99 power factor and harmonic distortion below 5% |
The R1X Pro Gen III draws 3,800 W to deliver 4.0 MH/s. This represents a 22% improvement in watts-per-megahash compared to the Gen II (950 W/MH versus 1,217 W/MH) and a massive 162% improvement over the Antminer X9 (950 W/MH versus 2,472 W/MH). The dual-redundant PSU configuration ensures uptime even if one power supply unit fails, a critical feature for large-scale professional mining operations.
2.4 Thermal and Cooling Architecture
| Component | Specification |
|---|---|
| Cooling Method | Hybrid liquid-air cooling: a closed-loop liquid cooling system for the compute chiplets and interposer, plus forced-air cooling for the memory and VRM components |
| Noise Level | 78 dBA (higher due to the liquid pump and high-CFM radiator fans) |
| Operating Temperature | 5 to 35 °C (derates linearly to 4.0 MH/s at 35 °C; above that, hashrate throttles to protect silicon) |
| Operating Humidity | 5 to 90% (non-condensing) |
| Cooling System | 240 mm radiator with dual high-static-pressure fans, integrated pump-block assembly, and a secondary air duct for VRM and memory cooling |
The Pro Gen III's thermal solution is the most advanced in the Pinecone lineup. The compute chiplets generate a high heat flux due to their dense 3nm logic and high clock speeds. Liquid cooling is necessary to extract that heat efficiently and maintain junction temperatures below 85 °C. The radiator is externally mounted or can be integrated into a rack-level cooling distribution unit for data center deployments.

The Pro Gen III includes multiple safety layers: over-current protection, over-voltage protection, under-voltage lockout, over-temperature shutdown, and leak detection. The liquid cooling loop is factory-sealed and pressure-tested, requiring no user maintenance for the warranty period.
7. Architecture Summary
The Pinecone R1X Pro Gen III is built on four revolutionary advancements that collectively enable the 4.0 MH/s milestone:
- Chiplet Scaling with 3nm Silicon - Moving to a 3nm-class process allows for higher transistor density and lower switching energy. The chiplet approach enables Pinecone to yield larger effective die sizes without being limited by reticle constraints, while also improving manufacturing yields.
- Silicon Interposer with L4 Cache - The active interposer provides ultra-low-latency connections between chiplets and the GDDR6 memory. The added L4 cache layer absorbs a significant portion of dataset read requests, reducing average memory latency to levels previously achievable only in simulation environments.
- Hybrid Liquid-Air Cooling - The 3,800 W thermal load cannot be managed by air alone in a compact form factor. The liquid loop extracts heat directly from the compute chiplets, while air cooling handles the memory and power stages. This hybrid approach enables sustained operation without thermal throttling under normal data center conditions.
- Redundant Power Architecture - The dual PSU design with 96% efficiency ensures that the Pro Gen III remains operational even during power supply failures, a critical factor for maximizing uptime and profitability in professional mining farms where downtime directly translates to lost revenue.
Final Delivered Capability: A 4.0 MH/s at 3,800 W RandomX flagship miner that delivers 2.6x better efficiency than the Antminer X9 and 22% better efficiency than the R1X Gen II. With its 4U rack-mountable form factor, the Pro Gen III achieves an industry-leading hash density of 1.0 MH/s per rack unit (4 MH/s across 4U), making it the ideal choice for high-density data center deployments.
