NI PXIe-6591 and PXIe-6592 Alternative: Conduant PXIe-8300 at 44 to 56% Below NI List Pricing
The Conduant PXIe-8300 replaces both the NI PXIe-6591 and PXIe-6592 with a current-generation AMD Kintex Ultrascale FPGA, PCIe Gen3 interface, and 4x the DRAM — at under $14,000. Same PXI Express form factor. Drops into your existing chassis without modification.
The PXIe-6591 and 6592 are among the clearest-case Conduant replacements in the NI lineup. Engineers respond within one business day.
Conduant PXIe-8300 — direct replacement for the NI PXIe-6591 and PXIe-6592
Why These Two Models Are Straightforward Replacements
The NI PXIe-6591 and PXIe-6592 use a Kintex 7 410T FPGA — a device that was released over a decade ago — on a PCIe Gen2 interface with 2 GB of DRAM. These are legacy specs by current standards. There is no tradeoff story here.
The Conduant PXIe-8300 is a current-generation board that exceeds the 6591 and 6592 on every spec except DSP slice count, where the comparison is close. It costs 44 to 56% less, fits the same chassis, and ships with working FPGA IP on day one. If you are replacing a 6591 or 6592, this is the page you need.
Spec Comparison
NI PXIe-6591 and 6592 vs Conduant PXIe-8300
The 6591 and 6592 are nearly identical boards — the primary difference is serial lane count. Both are replaced by the same Conduant board.
NI PXIe-6591 vs Conduant PXIe-8300
NI PXIe-6592 vs Conduant PXIe-8300
The 6592 carries the same FPGA and DRAM as the 6591 but ships with 4 serial lanes at 10.5 Gbps rather than 8 at 12.5 Gbps. The Conduant PXIe-8300 replaces it at an identical price point to the 6591 replacement.
Note on DSP slices: The PXIe-8300 carries 768 DSP48E2 slices vs 1,540 on the NI 6591/6592. For most general-purpose FPGA workloads this is not a constraint, but if DSP slice count is a hard design requirement, the PXIe-8324-DSP provides 5,250 DSP slices at $24,677.
