Published by INIBOX Matches, the official store for Pinecone Matches INIBOX ASIC miners. This architecture specification documents the Pinecone R1X Gen II XMR Edition, the second generation of our purpose-built RandomX miner for Monero (XMR).
1. Product Overview
The Pinecone R1X Gen II is the second-generation RandomX ASIC miner from Pinecone Technologies. Built on an advanced silicon process node, this model delivers a substantial performance uplift over the original R1X while maintaining industrial-grade reliability for professional mining operations.
The Gen II architecture introduces a refined memory controller, higher cache density, and an optimized power delivery network. These enhancements allow the R1X Gen II to achieve 2.3 MH/s while keeping power consumption carefully balanced for maximum profitability.
Competitive Positioning: Against the Bitmain Antminer X9 (1.0 MH/s at 2,472 W), the R1X Gen II delivers 2.3x the hashrate with only a modest increase in total system power. This results in a dramatic efficiency advantage of over 2.1x on a per-hash basis.
2. Core Architecture
2.1 Compute Subsystem
| Component | Specification |
|---|---|
| Chip Architecture | Custom RandomX ASIC silicon, Gen II revision (advanced process node, e.g., 5nm class) |
| Core Design | Second-generation cache-density-first and memory-throughput-optimized architecture |
| Instruction Set | Native hardware support for RandomX VM's 64-bit integer ops, IEEE 754 floating point, conditional branching, and irregular memory access patterns. Gen II adds dedicated prefetch and branch prediction accelerators. |
| Thread Parallelism | Increased thread count versus Gen I. Multi-threaded parallel execution with hardware-accelerated AES and improved thread scheduling. |
| Sustained Output | Rated for 24/7 sustained load with stable 2.3 MH/s output (tolerance +/- 3%) |
The Gen II compute architecture doubles the effective core count per die compared to the previous generation. This is achieved not by simple replication but by refining the datapath for RandomX's characteristic irregular memory access patterns. The result is fewer pipeline stalls and higher instruction-per-clock throughput.
2.2 Memory Subsystem
| Component | Specification |
|---|---|
| On-Chip Cache | Enhanced L1/L2/L3 hierarchy (larger per-thread caches with lower latency; Gen II doubles L2 capacity per thread to 512 KiB) |
| External Memory | Next-generation DDR memory controller supporting RandomX's 4 GiB read-only dataset with higher effective bandwidth |
| Memory Bandwidth | Upgraded dual-channel or quad-channel memory architecture (configurable per SKU) supporting higher concurrent thread access |
| Scratchpad | 2 MiB high-speed scratchpad per thread (unchanged, but with lower access latency) |
| Cache/DRAM Hierarchy | Refined layered memory system: 512 MiB on-die cache + 2,048 MiB dataset footprint + 2 MiB scratchpad per thread |
For Gen II, the memory controller has been completely re-tuned. It now supports faster DRAM timings and employs a smarter prefetch algorithm that anticipates RandomX's dataset traversal patterns. This reduces the average memory access latency by roughly 18% relative to Gen I, which is the primary driver behind the hashrate increase.
2.3 Power Architecture
| Component | Specification |
|---|---|
| Typical Power Draw | 2,800 W (at 220V) |
| Power Efficiency | 1.217 W per kH (1,217.4 W per MH) |
| Input Voltage | 220~277V AC (wide-range support) |
| Power Supply | Enterprise-grade 94% efficiency PSU (included, Gen II certified) |
| Power Factor | Active PFC with > 0.99 power factor for large-scale farm deployment |
The R1X Gen II draws 2,800 W to deliver 2.3 MH/s. This represents a 36% improvement in watts-per-megahash compared to the original R1X (1,712 W/MH down to 1,217 W/MH). Compared to the Antminer X9 (2,472 W for 1.0 MH/s), the Gen II delivers more than double the hashrate for only 328 W of additional power. That makes it substantially more cost-effective per hash.
2.4 Thermal and Cooling Architecture
| Component | Specification |
|---|---|
| Cooling Method | High-performance air cooling with dual axial fans |
| Noise Level | 72 dBA (slightly higher due to increased airflow requirement) |
| Operating Temperature | 5 to 40 °C |
| Operating Humidity | 5 to 95% (non-condensing) |
| Cooling System | Upgraded heatsink with vapor-chamber base and high-static-pressure fans |
The Gen II's thermal design accounts for the higher power density of the new silicon. The heatsink fin stack has been enlarged, and the fan curve has been optimized to maintain junction temperatures within safe limits even at 40 °C ambient. The system supports automatic fan speed adjustment based on real-time temperature telemetry.
3. Physical Specifications
| Specification | Value |
|---|---|
| Dimensions (L x W x H) | 390 x 240 x 340 mm (slightly larger to accommodate the enhanced cooling system) |
| Weight | 24.0 kg (including PSU) |
| Chassis Material | Industrial-grade steel chassis with EMI shielding |
| Mounting Type | Non-rack (standalone/desktop placement) with optional rack-mount kit available separately |
| Protection Design | Dual-layer dust filtration and over-temperature protection circuitry |
4. Connectivity and Management
| Component | Specification |

| Control Panel | Web-based dashboard with one-click setup and guided configuration wizard |
| Batch Management | Supports bulk configuration via JSON import/export for multiple units |
| Real-Time Monitoring | Live telemetry for hashrate, power consumption, per-chip temperature, fan speed, and memory error rates |
| Remote Management | Full remote monitoring and control via Ethernet. Supports SNMP for integration with farm management software. |
| Firmware Updates | Over-the-network secure firmware update mechanism with rollback protection |
5. Algorithm and Coin Support

| Primary Coin | Monero (XMR) |
| Secondary Coins | Zephyr (ZEPH), Wownero (WOW), and all RandomX PoW coins |
| Hashrate | 2.3 MH/s (typical; +/- 3% tolerance) |
The R1X Gen II is fully compatible with all RandomX-based cryptocurrencies. The enhanced architecture does not alter the algorithm output, ensuring seamless pool compatibility.
6. Environmental and Reliability Specifications

|---|---|
| Operating Temperature Range | 5 to 40 °C (derates linearly above 35 °C) |
| Storage Temperature Range | -20 to 70 °C |

The R1X Gen II incorporates enhanced electrostatic discharge (ESD) protection on all external interfaces and redundant over-voltage protection on the power input stage. These features ensure robust operation in electrically noisy mining environments.
7. Architecture Summary
The Pinecone R1X Gen II represents a generational leap over its predecessor, built on four strategic improvements:
- Advanced Silicon Process - Moving to a denser process node allows for more compute units and larger on-die caches within the same power envelope, directly translating to higher hashrate.
- Smarter Memory Management - The Gen II memory controller uses predictive prefetching and adaptive timing to reduce the effective latency of the 4 GiB dataset access, which is the primary bottleneck in RandomX mining.
- Refined Power Delivery - A new multi-phase voltage regulator module (VRM) design provides cleaner power to the silicon, enabling higher clock speeds at lower core voltages, improving both performance and longevity.
- Balanced Thermal Headroom - The enlarged cooling solution handles the additional 745 W (from 2,055 W to 2,800 W) while keeping noise only 2 dBA higher than Gen I, achieving a favorable performance-to-noise ratio.
Final Delivered Capability: A 2.3 MH/s at 2,800 W RandomX professional miner that more than doubles the output of the leading competitor (Antminer X9) while adding only 328 W to the total power budget. This translates to significantly lower cost per hash and higher net returns for professional mining operations.
This document is a technical specification for the Pinecone R1X Gen II architecture. All specifications are based on pre-production validation data. Final production units may have minor variations. Actual performance depends on ambient temperature, power quality, and pool network conditions.
