Market leader for PCIe Gen 5 accelerators

As the market leader for PCIe 5.0 accelerators and expansions, we are the best possible contact for all questions relating to PCI Express. Of course, this also applies to Gen 4 or Gen 3 slots!

The transmission speed for PCIe depends on the version and the number of links or lanes. The higher the version and the more links, the higher the bandwidth and the higher the transmission speed. The bandwidth indicates how much capacity is theoretically or at most available for data transfer. However, the actual data rate is lower.

Supports the latest graphics cards

Depending on the rack unit height, you can choose from various GPUs: NVIDIA® RTX-5090, NVIDIA® RTX-4090, NVIDIA® Tesla, Intel Xeon Phi, AMD FirePro, GeForce GTX Titan X, Nallatech FPGA, and GeForce GTX 1080. Additionally, we offer not only the standard server rack versions but also desktop versions for applications outside of server enclosures. Selected GPU expansions even provide multiple PCIe x16 Gen5, Gen4, or Gen3 host connections, ensuring connectivity is seamless and supporting peer-to-peer transfer.

This flexibility enables you to optimize the system for your specific workload, whether for AI, machine learning, or data-intensive simulations. Our systems are designed to provide maximum GPU density while ensuring optimal cooling and energy efficiency.

When does an upgrade to PCIe Gen5 make sense for my project?2025-02-03T16:26:31+01:00

An upgrade to PCIe Gen5 is particularly worthwhile if your project benefits from increased bandwidth and lower latency. PCIe Gen5 offers a data rate of up to 32 GT/s (gigatransfers per second)—twice the speed of PCIe Gen4—allowing for significantly faster communication between GPUs, CPUs, and storage devices.

When does an upgrade make sense?

  • High-Performance Computing (HPC): If you process large datasets or run simulations, PCIe Gen5 ensures faster data transfers and reduces bottlenecks.
  • AI and Machine Learning Workloads: For multi-GPU models or frequent data access, PCIe Gen5 significantly improves efficiency.
  • NVMe Storage: PCIe Gen5 enhances the performance of modern NVMe SSDs, which can achieve extremely high data rates.

However, if your current infrastructure is not limited by bandwidth constraints, upgrading may not be immediately necessary. Our experts are happy to assist in evaluating the best solution for your needs.

What cooling options does BRESSNER offer for GPU servers?2025-02-03T16:28:00+01:00

BRESSNER Technology offers various cooling options for GPU servers to ensure optimal performance and longevity, even under intensive workloads.

  • Fan Cooling:
    The classic and proven solution, using high-performance fans for efficient heat dissipation. This option is suitable for standard applications in climate-controlled server rooms.
  • Liquid Cooling:
    This method provides excellent cooling performance with lower noise levels. It is ideal for scenarios with high thermal demands, such as GPU servers packed with high-performance components.
  • Immersion Cooling:
    For maximum efficiency and minimal energy consumption, BRESSNER offers immersion cooling, where servers are fully submerged in a thermally conductive liquid. This solution is especially beneficial for data centers with extreme performance requirements, as it effectively dissipates heat and reduces operating costs.

The choice of cooling technology depends on the specific needs of your project, particularly regarding performance, energy efficiency, and environmental conditions.
