TeraBox 1401B

Extreme Density Standard-Depth FPGA Server

1U, 4 card, PCIe Gen4 x16, AMD EPYC 7002 series


At the extreme of FPGA server density, the TeraBox 1401B gives the highest level of compute and network capability in a 1U chassis. This server provides twice the density of the typical 4U server and the power of 4 of our largest Achronix Speedster7t, Intel Stratix 10 or Xilinx UltraScale+ FPGAs. This innovative product supports PCIe Gen4 and features an AMD EPYC processor in a standard rack depth chassis.


Carlos Tejeda explains features of the new TeraBox 1401B.

Generation 4.0

Double the Bandwidth!

The TeraBox 1401B is ready for Gen4-equipped cards with twice the bandwidth per lane of Gen3.

BittWare FPGA Cards

The TeraBox 1401B supports up to four dual-slot BittWare PCIe FPGA cards. Choose from a variety of cards based on the Speedster 7t, Stratix 10, or UltraScale+ FPGAs. System specs will vary greatly, depending on the FPGA card you select. For example, with four BittWare UltraScale+ PCIe cards, which support up to 512 Gbytes of DDR4 per card, the chassis can support as much as 2 Terabytes of DDR4 on the FPGA cards in 16 banks. With four Agilex cards using breakout cables, each chassis supports 48x 100GbE.

BittWare 1U Server

The TeraBox 1401B server featuring AMD EPYC processor is exclusive to BittWare and is the ideal platform to unleash the energy-efficient acceleration of BittWare’s FPGA cards. This FPGA-optimized 1U server delivers unrivaled performance density and value for a range of compute-intensive applications, including machine learning.

The server is assembled in the USA, is TAA compliant, and offers a 3-year warranty.
