NI PXIe-659x Series Alternative: Conduant PXIe FPGA Boards with Higher Specs at Lower Cost
The Conduant PXIe-8300 replaces the NI PXIe-6591, 6592, 6593, and 6594 with a current-generation AMD Kintex Ultrascale FPGA, PCIe Gen3, and 8 GB DRAM. It seats in the same PXI Express chassis your team is already using.

Conduant PXIe-8300 — direct replacement for the NI PXIe-6591, 6592, 6593, and 6594
Spec Comparison by Model
NI PXIe-659x vs Conduant — Side by Side
Each table shows the specific NI model against its Conduant replacement. Pricing reflects NI published list price versus Conduant standard pricing.

NI PXIe-6593 Alternative
The NI PXIe-6593 ships with either a KU040 or KU060 FPGA depending on configuration. Both Conduant options exceed the KU060 in logic capacity. The PXIe-8300 is the value path; the PXIe-8324-DSP adds higher DSP slice count for signal processing workloads.
NI PXIe-6594 Alternative
The NI PXIe-6594 uses a Kintex Ultrascale+ KU15P and includes four Interlaken cores. The Conduant PXIe-8300 covers most workloads at lower cost. For DSP-intensive applications the PXIe-8324-DSP delivers 5,250 DSP slices versus 1,968 on the NI, in addition to higher overall logic capacity.
Note: The NI PXIe-6594 has higher DRAM bandwidth (42.7 GB/s) than the Conduant options. If your application is DRAM bandwidth-constrained, discuss this with our engineers before selecting a replacement.
Conduant PXIe-659x Replacements
Two Boards. One Decision.
The PXIe-8300 handles most 659x replacements at the best price. The PXIe-8324-DSP is the option when DSP slice count is the primary driver.
Conduant PXIe-8300
$13,577
The primary replacement for the NI PXIe-659x series. AMD Kintex Ultrascale KU095 FPGA with PCIe Gen3 x8, 24 high-speed serial lanes, and 8 GB DRAM. Core FPGA IP for PCIe, memory, and serial interfaces ships with the board.

Chassis Compatibility and Integration Notes
PXI Express Form Factor
Both boards use the standard PXI Express single-slot form factor and are validated in NI PXIe chassis including the PXIe-1073, 1078, 1085, and 1095, as well as Keysight M9010A, M9019A, M9046A, and M9018A.
Backplane Clocks and Triggers
Full PXIe backplane signal support including triggers and clocks. Multi-card synchronization works the same way it does with NI boards in the same chassis.
FPGA IP and Development
Core IP for the PCIe interface, DDR3 memory controller, and high-speed serial interfaces ships with the board. Your team handles application logic. No third-party IP licensing required.
Engineering Support
US-based engineers support evaluation and integration. Reach them directly through the Conduant support portal or via consultation request.
