NVIDIA CMP 40HX Graphics Card 8 GB

The CMP 40HX is an enthusiast-class professional graphics card by NVIDIA, launched on February 25th, 2021. Built on the 12 nm process, and based on the TU106 graphics processor, in its TU106-100-A1 variant, the card supports DirectX 12 Ultimate. The TU106 graphics processor is a large chip with a die area of 445 mm² and 10,800 million transistors. It features 2304 shading units, 144 texture mapping units, and 64 ROPs. Also included are 288 tensor cores which help improve the speed of machine learning applications. The card also has 36 raytracing acceleration cores. NVIDIA has paired 8 GB GDDR6 memory with the CMP 40HX, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 1470 MHz, which can be boosted up to 1650 MHz, memory is running at 1750 MHz (14 Gbps effective).

Being a dual-slot card, the NVIDIA CMP 40HX draws power from 1x 8-pin power connector, with power draw rated at 185 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. CMP 40HX is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card’s dimensions are 229 mm x 111 mm x 35 mm, and it features a dual-slot cooling solution. Its price at launch was 699 US Dollars.

Key Features:

1. Mining-Focused Design

1. • Headless Architecture: No display outputs, ensuring all hardware and power usage is dedicated purely to cryptomining.
   • Dedicated Mining Drivers: NVIDIA’s specialized driver stack focuses on maintaining steady hash rates for memory-intensive algorithms, rather than gaming performance or multi-display support.

2. Competitive Hash Rate

1. • Approx. 36–40 MH/s: Typically provides a stable Ethereum (ETH) mining rate in the mid-tier range. Exact hash rates depend on environment, overclocks, and driver optimizations.
   • Optimized Memory Speed: GDDR6 memory ensures adequate bandwidth for Ethereum’s DAG file and other altcoin algorithms, enabling consistent performance.

3. Power and Thermal Management

1. • 24/7 Mining Ready: Intended to run continuously under heavy load, with robust VRM designs and cooling solutions from board partners.
   • TDP Range (~185–200W): Delivers a moderate power draw that can be efficiently managed with proper airflow and stable power supplies.

4. Scalable Deployments

1. • Plug-and-Play Mining: Straightforward integration into specialized mining motherboards or standard rigs, simplifying large-scale rollouts.
   • No Gaming Overheads: Frees up resources by excluding rendering features or display capabilities unnecessary for cryptomining.

5. Reduced Demand on Gaming GPUs

1. • Dedicated for Mining: By offering CMP models like the 40HX, NVIDIA aims to keep standard GeForce GPUs more accessible to gaming and creative users.

Applications:

1. Cryptocurrency Mining

1. • Ethereum (ETH): The 40HX’s memory configuration and stable driver environment cater to Ethereum’s memory-intensive mining algorithm.
   • Other GPU-Mined Coins: Potentially suitable for altcoins using Proof-of-Work models reliant on GPU memory.

2. Professional Mining Farms

1. • Large-Scale Operations: Mining facilities requiring efficient, stable hash rates can utilize multiple 40HX boards in server-like or open-air mining racks.
   • Continuous Operations: Built for sustained load, ensuring reliable output over extended periods.

3. Mid-Level Mining Rigs

1. • Cost-Effective Setup: Enthusiasts or smaller-scale miners can integrate 40HX GPUs to achieve moderate hash performance without diverting consumer GeForce cards.
   • Stackable Solutions: Combine multiple 40HX units on motherboards with multiple PCIe slots for cumulative hash rate gains.
