The setup is almost complete – the switches are in place. The only missing piece is NICs. What’s available on the market tends to be outdated (like Intel x710/810, Cx4/5) or prohibitively costly (Cx6/7). These options are aimed at data centers, which demand cutting-edge technology. To achieve 25GbE you’d need to look back in time – using older hardware when 25GbE was still a novelty. This usually means outdated components, high power consumption, and legacy PCIe versions (often PCIe3). Prices are steep, and there’s often a “retro tax” involved.
Is there any upcoming solution similar to what Acquantia introduced for 10GbE? I’m confident it would find an audience and create new opportunities. Since PCIe5x1 can easily support 25GbE with plenty of headroom, and 100GbE would fit comfortably in PCIe5x4 (like M.2 cards), these technologies could shift advanced networking from traditional copper setups to next-gen solutions.
While switches exist, NICs remain scarce. I once hoped Intel would revive the E830 line, but that path has quieted. ServeTheHome hinted at Chelsio and a major upcoming release, though their S7/T7 chipset isn’t particularly compact. If it becomes affordable, it could be a strong contender.
For PCIe5x1 or 5x4, 25GbE makes sense for niche advanced home networks or SOHO setups. Even with added features to stand out from datacenter offerings, 100GbE on PCIe5x4 would also fit neatly. Any rumors or leaks about such developments are scarce, but the trend seems clear – more aggressive pricing and innovation could emerge soon.
Currently there’s a noticeable gap, you’re correct. Used and refurbished switches have become more affordable, but NICs remain limited to older Intel chips or data center models, mainly based on pricing. From what I’ve observed, genuine Aquantia 25GbE devices aren’t available yet. After Aquantia was acquired by Marvell, their focus shifted toward automotive and OEM partnerships, leaving enthusiast-grade NICs in the background. Regarding 25GbE options: Chelsio T6/T7 offers solid performance but is power-intensive and expensive. Mellanox ConnectX-4/5 are common on the second-hand scene, though they still require PCIe3 and consume more idle power. Intel’s E810/E830 series is advancing toward 100/200GbE PCIe5, but they’re not yet suitable for consumer or budget 25GbE needs. I haven’t found any solid information about a low-power, affordable PCIe4/5 25GbE NIC. In the near term, the best choices seem to be: repurposed Mellanox cards with stable firmware, or keeping an eye on Intel’s potential entry with a more compact E830 variant for OEM use—sometimes Dell or HP contracts trigger those releases. Overall, I agree there’s a significant market gap. A dedicated single-chip PCIe4 x1 25GbE NIC could dominate the prosumer space, but until someone pursues that niche as Aquantia did for 10GbE, we’re stuck with outdated solutions or leftover data center parts.
