I am happy with my 2014 vintage PC; I have no need to replace it. I just recently installed another 32 TB of magnetic disk, and will get a 1 TB M.2 system disk next week - that will keep the PC going for a few more years Smile | :)

Before ordering the M.2 disk, I checked the motherboard user guide to make sure it would accept it. The guide listed the PCIe capacities with "40 lane" and "28 lane" CPUs. Mine, an i7 5820K, has "only" 28 PCIe lanes.

So I checked up the Core CPUs of today, to see which models would provide more, starting at the top of the list from Intel, sorted by release date. I gave up before I found any model with more than 20 (which they all had). I also noticed that while my old CPU has four memory channels, most new ones only have two.

I am certainly no hardware expert, but to me, this looks like a downgrade, on both points. In spite of significant faster memory chips today, the max memory bandwidth is only marginally higher (less than 15%) on today's CPUs.

I am curious about why this is so. Did Intel conclude that PCIe wasn't such a great success after all - there is no need for that many lanes? With my Asus X99-A/USB3.1 board, I can plug in and bridge together three GPU cards. Nowadays, it seems as if most users want a single super-powerful card. Is that why we don't need that much PCIe any more? In 2014, I expected super-speed network interface boards to be PCIe based. I expected super-speed storage to be PCIe based, but all I see is a single M.2 socket. Does it tell that PCIe was (at least partially) a flop, replaced by USB4 for network, disks and other uses?

For the memory bandwidth: Did Intel conclude that memory bandwidth isn't any serious bottleneck at all?

Maybe I am right in concluding that my 2014 vintage PC is good enough for a few more years ...
