The TYAN Transport HX TN85-B8261 family can be configured as a storage-heavy or GPU-heavy rig, solving a variety of use cases.
The TYAN Transport HX TN85-B8261 is a new dual-socket AMD EPYC 9004 platform, geared towards heavy storage I/O and GPU workloads. This barebones server can support up to two full-height double-width GPUs, 24 U.2 NVMe SSDs, as well as up to 6TB of DDR5 memory. In our review, we explore its performance leveraging dual AMD EPYC 96-core Genoa CPUs, as well as application-specific 128-core 9754S Bergamo CPUs with SMT disabled for HPC workloads.
TYAN Transport HX TN85-B8261 Features
The ability to support two AMD EPYC 9004 Series Processors makes the Tyan Transport an ideal candidate for environments where computational power and storage capacity are paramount. Previous Tyan platforms in our lab supported the AMD EPYC 9004 Series CPU in a single-socket form, this is the first dual-socket AMD 9004 platform we’ve seen from the company.
Our server version offers 24 NVMe drive bays (with toolless caddies), catering to storage-heavy configurations. Tyan also offers a version with eight NVMe drives in front, using the lanes instead to support up to four 4 double-wide GPUs. The configuration choice depends on the user’s specific needs, whether it’s storage density or AI power.
For memory support, the TN85-B8261 can accommodate RDIMM DDR5 memory at speeds up to 4800 MHz for one DIMM per channel (1DPC) and 3600 MHz for two DIMMs per channel (2DPC), along with 3DS RDIMM DDR5 3600MHz for 2DPC configurations. With support for up to 6,144GB of RDIMM/3DS RDIMM DDR5 memory (via 12 memory channels per CPU, for a total of 24), this server has the capabilities for an impressive DRAM footprint.
On the front panel’s left side are two USB 3.2 Gen.1 ports, and on the right are the reset and power buttons and the status LED indicators. Turning it around to the rear side reveals the test of the connectivity, including an additional two USB3.2 Gen.1 ports, two 10 GbE RJ-45 ports for high-speed networking, plus a dedicated GbE port for IPMI, a VGA port, and two hot-swap 2,700 Watt PSU modules. Two optional 60mm rear fans on either side are also supported, with power headers visible on the far left and right side of the chassis. These would be used in a situation that requires extra airflow for certain PCIe devices like accelerators.
It took us a few minutes to figure out how to take the cover off to look inside; however, while doing that we got distracted and discovered an interesting ‘sunroof’ mini lid. Removing the panel provides easy access to the server’s six high-powered hot-swap fans and the NVMe bays.
Upon removing the full lid, the first thing that stands out is that the TN85-B8261 features direct CPU access to all 24 NVMe bays, significantly enhancing performance and reducing latency for storage operations. This feature allows direct paths between the CPUs and the storage, ensuring that data-intensive applications perform at their peak without bottleneck issues. The one downside to this approach though is the need for all of these PCIe lanes, which limits the rear expansion options.
In the back, you can see the many PCIe cables connecting the front NVMe bays to different locations on the motherboard. In this photo you can see two PCIe cards loaded into the left and right side of the server, leaving one double-width full-height slot on each side for a GPU. In the middle are two half-height slots for other devices. In our setup, one slot is populated with a PCIe M.2 SSD sled.
The TN85-B8261 server also has out-of-band server management features via the Aspeed AST2600 onboard chipset. The AST2600 chipset introduces the iKVM feature with 24-bit high-quality video compression support. This allows easy remote console access, which is crucial for managing servers in data centers or remote locations.
This feature also enables storage over IP, remote platform flash, and a USB 2.0 virtual hub. These capabilities let administrators perform a range of remote management tasks, like updating firmware or OS installation, without needing physical access to the server, ensuring operational efficiency and reducing downtime. This service leverages its own dedicated LAN port, separate from the two onboard 10GbE ports.

TYAN Transport HX TN85-B8261 Performance
To provide a comprehensive performance analysis, our benchmarks encompass a variety of intensive tests, each targeting different aspects of CPU performance. We use Blender OptiX for rendering performance, Blackmagic to assess video processing capabilities, and Geekbench for overall system performance evaluation. Cinebench will give us insights into graphics and rendering efficiency, y-cruncher for mathematical computations, and 7-Zip compression tests to gauge data processing and compression speeds.
This review will focus on the compute side of things rather than storage performance.
Tyan Transport HX TN85-B8261 main components:
- 8 x 64GB Kingston DDR5 RAM
- Tested on Windows Server 2022
We used two different CPU configurations for benchmarking: the 96-core AMD EPYC 9654 and the 128-core AMD EPYC 9754S (SMT Disabled). This analysis will show the performance benefits of using processors with higher core counts and enhanced capabilities within the same system architecture. By contrasting these EPYC 9004 CPUs, we can highlight the potential gains in processing efficiency and task execution speed. We also compared it to two Dell PowerEdge Servers powered by one, and two, of the AMD EPYC 9354 32-core processors just to show scale within the AMD CPU family.
Blender OptiX
Blender is an open-source 3D modeling application. This benchmark was run using the Blender Benchmark utility. The score is samples per minute, with higher being better.
The Blender OptiX benchmark on the Transport HX TN85-B8261 server, comparing dual AMD EPYC 9654 (96 cores) and AMD EPYC 9754S (128 cores), reveals interesting performance differences in 3D modeling tasks. In the “Monster” scene, the 128-core EPYC 9754S slightly outperforms the 96-core EPYC 9654, showing a modest improvement in rendering speed with 1,480 samples per minute versus 1,448.
However, in the “Junkshop” scene, the 96-core configuration leads with 1,009 samples per minute, compared to 943 for the 128-core setup. This indicates that more cores (without SMT) don’t guarantee better performance for all rendering tasks. The “Classroom” scene results are nearly identical, suggesting that the advantage of additional cores diminishes for certain types of workloads.

The UL Procyon AI Inference benchmark with dual AMD EPYC 9754S (128 cores) reflects increased inference times across various AI models compared to its 96-core counterpart. For example, inference times for MobileNet V3, ResNet-50, Inception V4, DeepLab V3, and YOLO V3 all increased, suggesting that additional cores do not improve AI task performance linearly. The Real-ESRGAN model‘s time significantly rose to 4529, indicating complex tasks might not benefit directly from more cores. The overall score dropped to 62 from 92, highlighting that higher core counts don’t guarantee better AI inference efficiency.
y-cruncher
y-cruncher is a multi-threaded and scalable program that can compute Pi and other mathematical constants to trillions of digits. Since its launch in 2009, it has become a popular benchmarking and stress-testing application for overclockers and hardware enthusiasts.
The y-cruncher benchmark results for the Transport HX TN85-B8261 illustrate a clear pattern: the 128-core configuration consistently performs better across all computational tasks, from calculating 1 billion to 25 billion digits of Pi. This is one test where SMT disabled really shines.
For computing 1 billion digits, the 128-core CPU completed the task in 13.764 seconds, compared to 15.088 seconds by the 96-core CPU, showing a noticeable improvement. This trend of enhanced performance by the 128-core configuration is consistent as the complexity of the task increases. At 2.5 billion digits, the time reduced from 26.626 to 23.266 seconds; at 5 billion digits, from 45.696 to 40.520 seconds; and for 10 billion digits, from 83.853 to 77.635 seconds. The most extensive computation tested, 25 billion digits, saw a reduction from 213.950 to 201.693 seconds.
