400G + PCIe Gen5 Single-Width Card

IA-780i card

Compact 400G Card with the Power of Agilex

The Intel Agilex 7 I-Series FPGAs are optimized for applications that are bandwidth intensive and require high performance processor interfaces.

  • 2nd-Generation HyperFlex Architecture: Up to 40 percent higher performance or up to 40 percent lower total power compared with Stratix 10 FPGAs.
  • 400G: Configurable networking support for the most demanding bandwidth requirements.
  • PCIe Gen5 and CXL Support: Data transfer speeds 2x faster than Gen4, and high-speed interface between CPUs and workload accelerators.

400G Networking

IA-780i provides up to 400G to support the most demanding bandwidth requirements. Configurable networking support includes hard Ethernet media access control (MAC), physical coding sublayer (PCS), and forward error correction (FEC) for a range of speeds.

2nd Gen Intel® Hyperflex™ Architecture

Continuous improvements to Intel Hyperflex deliver improved performance compared to Stratix 10 device designs. The 2nd Gen architecture thus greatly improve the productivity of customers and reduce time-to-market.

PCIe Gen5 and CXL

PCIe Gen5 supports data transfer speeds 2x higher than PCIe Gen4, providing greater performance capabilities to developers of PC interconnect, graphics adapters, and chip-level communications. And Compute Express Link (CXL) support enables high-speed, low-latency interface to CPUs.

Generation 5.0

Double the Bandwidth!

Built with the latest PCIe Gen5 interface, the IA-780i can transfer up to twice the bandwidth of Gen4 devices.

Enterprise-class for Deployment

Ramp to product with the power of Molex

The IA-780i is built on BittWare’s enterprise-class foundation stones: existing products and processes that are already proven through extensive validation. When it’s time to ramp to production, this means a faster turnaround and utilizing the same hardware you have been using for development.

400G Networking

QSFP-DDs provide up to 400Gbps with hard IP for 10/25/100GbE links (up to 4× 100GbE total).

Inquire about customized Molex connectors/cables as required for your application.

Supporting CXL

CXL (Compute Express Link) is an industry-supported cache-coherent interconnect between processors, memory expansion, and accelerators. CXL technology maintains memory coherency between the CPU memory space and memory on attached devices, which allows resource sharing with lower latency, reduced software stack complexity, and lower overall system cost. 

* CXL requires licensing that is sold separately from the card

Supporting Intel's oneAPI

Develop faster + reuse code in this software-orientated tool flow

Supporting high-level software tool flows is critical to a growing customer base who want to take advantage of heterogenous architectures. The new oneAPI from Intel is designed around code re-use while providing similar performance to other high-level tools.

BittWare recently completed an updated 2D FFT white paper using oneAPI and found the performance matches our optimized OpenCL-based approach.


IA-780i Block Diagram, Data Sheet and Specifications

To access USB and/or JTAG, you need accessory cables. Choose from these options:

  • USB-only breakout cable: Pico-lock to USB A cable, BittWare part number RS-PL05-UAP-83.
  • JTAG-only breakout cable: Pico-lock to JTAG cable, BittWare part number RS-PL06-JTB-13

We recommend the combination JTAG cable for development. For deployment, the USB-only breakout cable is recommended.

These accessory cables are sold separately.
