AFAIK PCIe6 just started getting implemented in hardware last year... PCIe7 Spec was just released last year too... PCIe6 is a much larger change than 'just bump up the transfer rate', the encoding changed too (on top of the new code length, it's no longer NRZ,) so everyone needed to design and validate both the new encoding block, negotiation, etc etc. That said, I'm guessing PCIe7 will be a 'smoother' transition from PCIE6, i.e. we might see 7.0 products in 2027. That will theoretically get you ~240GB/sec, on an x16 link, or hypothetically a little less than the hypothetical max of a current Strix Halo. (I'm guessing however, that PCIe protocol overhead will make the difference larger.) |
