alt Hacker NewsAmazon aside, interesting future here with NVLink getting more and more folks using it. Intel is also onboard with NVlink. This is like an PCI -> AGP moment, but Nvidia's AGP.
AMD felt like they were so close to nabbing the accelerator future back in HyperTransport days. But the recent version Infinity Fabric is all internal.
There's Ultra Accelerator Link (UALink) getting some steam. Hypothetically CXL should be good for uses like this, using PCIe PHY but lower latency lighter weight; close to ram latency, not bad! But still a mere PCIe speed, not nearly enough, with PCIe 6.0 just barely emerging now. Ideally IMO we'd also see more chips come with integrated networking too: it was so amazing when Intel Xeon's had 100Gb Omni-Path for barely any price bump. UltraEthernet feels like it should be on core, gratis.
NVLink Fusion sounds like a total trap where you pay to become Jensen's slave. It may make sense for Intel because they're desperate. It's not a good look for AWS to put themselves in the same category.

I've been saying for a while that AMD should put a SolarFlare NIC in their I/O die. They already have switchable PCIe/SATA ports, why not switchable PCIe/Ethernet? UEC might be too niche though.
