Plus, with a 350W thermal design power (TDP), this processor can sustain peak performance over long periods. The AS-2115HV-TNRT’s six heavy-duty fans keep things cool, even when handling demanding workloads.

We’re using the AMD Ryzen Threadripper PRO 7995WX for the AS-2115HV-TNRT. This top-tier option in the series boasts an impressive 96 cores and 192 threads, making it a perfect choice for handling extreme multi-threaded workloads.

The system can be outfitted with up to 2TB of DDR5 memory with speeds of up to 5200MT/s and ECC (Error-Correcting Code) memory for applications where data integrity is critical. ECC detects and corrects single-bit memory errors that could go unnoticed in non-ECC setups. For users seeking to squeeze even more performance from the AS-2115HV-TNRT, it also supports memory overclocking, allowing DDR5 speeds to be pushed even higher when necessary. However, it’s essential to be wary of the system’s cooling limitations and ensure proper cooling before pushing the hardware to its limits.

As we’ve seen with other rack-mount workstations, such as the HP Z4 Rack G5, putting desktop GPUs in a pass-through airflow system can restrict airflow to the GPUs. The NVIDIA RTX 6000 Ada draws its air in front, above, and below the GPU, which turns into a very tight fit in a server-style chassis. As you can see above, the intake ports are sandwiched against the case, another GPU, or the top lid of the system. We didn’t see any overheating issues, but it is one thing to keep in mind when pushed to the max over extended periods.

The AS-2115HV-TNRT also supports the PCIe Gen5 interface and up to four full-length, double-width GPUs, ideal for tasks that require GPU-accelerated computing, including deep learning, high-resolution 3D rendering, and complex video editing. This is especially useful in AI model training, where data constantly flows between storage, GPU, and CPU.

Moreover, the new Supermicro system provides eight front-accessible 2.5″ hot-swappable bays that support NVMe, SAS, or SATA drives, making it easy to configure for either speed or storage density, depending on the application. With two M.2 PCIe 4.0 slots, users can install high-speed NVMe SSDs directly on the motherboard, perfect for applications needing ultra-fast storage access, whether as a boot drive or for frequently accessed data.

The AS-2115HV-TNRT also offers a range of redundant power options. Standard configurations include dual 2600W Titanium-level redundant power supplies, with optional 1600W or 2000W setups for environments requiring different power redundancy levels. This redundancy ensures continuous operation even if one power supply fails and provides stability crucial for critical workloads where uptime is a priority.

In addition, the AS-2115HV-TNRT comes equipped with enterprise-grade management features for remote monitoring and maintenance. With a dedicated BMC LAN port, IT administrators can remotely access and control the system—an essential tool for maintaining performance and troubleshooting issues in multi-rack setups. Supermicro’s management software suite (such as SuperCloud Composer and SuperDoctor) offers comprehensive tools for monitoring system health, temperature, and performance metrics, ensuring smooth operation and efficient resource allocation.

This workstation is built with functionality and easy maintenance in mind, making it an excellent choice for data centers, research labs, and environments running demanding applications.

The front panel of the AS-2115HV-TNRT features a control panel with LED indicators and eight 2.5″ NVMe/SATA/SAS hot-swap drive bays right in the center of the system. Each bay has an activity indicator, so you can quickly check the status of individual drives at a glance. This setup makes adding or replacing storage easy without needing to power down the system, making maintenance and upgrades simple—especially in data-heavy environments.

The control panel is simple and easy to navigate, with LED indicators for critical system statuses. It has LEDs for power, drive activity, network activity (NIC1 and NIC2), power failure, and system information. There’s also a UID button to help locate the system in rack environments and a power button to manage power states. This design makes it easy for operators to monitor the system’s health in real time, and the UID feature adds extra convenience in multi-rack setups.

The rear of the AS-2115HV-TNRT has all the connectivity and power redundancy options you need. It’s equipped with dual 2600W Titanium-level redundant power supplies, so it can keep running even if one power source fails. For connectivity, you get two USB 3.2 ports, a VGA port, and a dedicated BMC LAN port for remote management.

The rear panel also supports flexible PCIe 5.0 expansion, allowing for either four x16 slots or eight x8 slots. This setup can handle a wide range of hardware, including up to four double-width GPUs, which makes it perfect for demanding tasks like AI training, data analysis, and complex simulations. Plus, it features an AIOM/OCP NIC 3.0 slot, offering advanced networking options for high-speed data processing and transfers.

Removing the top cover on the AS-2115HV-TNRT was easy. With just a press of the release lever at the rear, we slid the cover back and lifted it off, giving us quick access to all the internal components. As expected from Supermicro, the components are well organized and designed for tool-free adjustments, making any future setup or configuration smooth and hassle-free.

Six heavy-duty fans are positioned across the CPU, memory, and PCIe slots to help maintain stable temperatures during intense workloads. The single AMD Ryzen Threadripper PRO 7995WX processor is centrally located, with eight DIMM slots arranged to support up to 2TB of DDR5 ECC memory. The two M.2 slots for boot storage are accessible from the top, providing flexibility to dedicate the front-mount 2.5″ bays for high-capacity and high-speed storage configurations.

While the system’s internal design has some decent airflow, it’s essential to be mindful of the AS-2115HV-TNRT’s cooling limitations when adjusting performance profiles (i.e., overclocking), as the air cooling may be insufficient for excessive thermal loads.

Is it Really a Workstation?

The Supermicro AS-2115HV-TNRT is sold as a workstation, although many of our social media followers have debated hotly, “What makes this different from a traditional server?” On the workstation side of the ledger, the system offers end-user GPUs and a prosumer CPU. It also provides plenty of server-type features though, such as a 2U rack-mount form factor, eight U.2 NVMe SSD slots in front, and redundant power supplies in the rear.

Much of the differentiation in qualifying this system as a server or workstation will be the use case. The workstation naming fits best if its primary access mode is local control with a single-user OS (Windows 11). If the access will be over a multi-user OS (Windows Server) over a shared network, a server is probably the best bucket to place it in. In either event, it’s a fantastic piece of hardware that benefits from the obvious flexibility that fuels the debate over its proper designation.

Supermicro AS-2115HV-TNRT Performance

As always, we’ll be putting the new Supermicro AS-2115HV-TNRT through a series of rigorous benchmarks to evaluate its performance across a range of demanding workloads.

y-cruncher is a multi-threaded and scalable program that computes Pi and other mathematical constants to trillions of digits. Since its inception in 2009, it has become a popular benchmarking and stress-testing tool for overclockers and hardware enthusiasts. The program’s ability to utilize all available CPU threads makes it an excellent test of processing power and system stability.

The non-overclocked Supermicro AS-2115HV-TNRT performed well under multi-threaded tasks, completing the 10-billion-digit Pi calculation in 67.849 seconds. The overclocked version significantly improved this, completing the same task in 58.283 seconds. Across smaller digit calculations, the non-overclocked version held its own, providing reliable performance, but the overclocked configuration noticeably outpaced it in handling extreme computational loads. Nonetheless, both configurations are highly capable of performing large-scale computations.

y-cruncher BBP

This y-cruncher benchmark utilizes the Bailey-Borwein-Plouffe (BBP) formulas to compute massive hexadecimal digits of Pi, measuring the CPU’s total computation time, utilization, and multi-core efficiency.

In the 100 BBP test, the non-overclocked Supermicro AS-2115HV-TNRT had an impressive multi-core efficiency of 98.90% with a total computation of 21.434 seconds. This demonstrates that it can effectively distribute its workload across its cores, making it ideal for CPU-heavy applications.

The overclocked configuration completed the 100 BBP test faster, with a time of 15.876 seconds. However, it showed a slightly lower multi-core efficiency at 98.84%. This minor drop in efficiency could be due to the added thermal and power strain from overclocking, which can sometimes lead to diminished returns in terms of overall system balance. In the smaller tasks, such as the 1 BBP and 10 BBP tests, the overclocked system outpaced the non-overclocked version, completing the 1 BBP test in 0.178 seconds compared to 0.256 seconds. The overclocking allowed for faster results overall, but the system was pushed closer to its limits, potentially introducing instability under sustained workloads.

7-zip Compression Benchmark

The built-in memory benchmark in the 7-Zip utility measures the performance of a system’s CPU and memory during compression and decompression tasks, indicating how well the system can handle data-intensive operations. We run this test at a 128MB dictionary size when possible.

This benchmark test was conducted using OctaneBench, a popular tool that measures the rendering performance of GPUs with the OctaneRender engine. The test includes various scenes and kernels (rendering methods) to simulate different lighting and tracing conditions, giving insight into the hardware’s efficiency under realistic workloads. The results below show the performance in “Ms/s” (megasamples per second) and compare it with a GTX 980 reference.

The info channels kernel is the fastest, outperforming other methods in every scene. For instance, the ‘Box’ scene hits an impressive 3878.27 Ms/s. Direct lighting requires more power but still holds up well, reaching 928.51 Ms/s in the ‘Interior’ scene—nearly double the speed of the most demanding method, path tracing. Path tracing, which focuses on simulating realistic lighting by tracking complex light interactions, is much slower. In the ‘ATV’ scene, for example, it only manages 694.32 Ms/s. With a final benchmark score of 5059.88, this GPU certainly demonstrates that it can handle a range of tasks well overall, but the choice of method will depend on whether you prioritize speed or realistic detail.
