AMD definitely has a recent high end desktop/workstation platform with its ThreadRipper Pro WX CPUs (EPYC server CPUs) that have 128 PCIe 4.0 lanes and 8 memory channels. And enough PCIe slots to actually use this throughput with the right kind of hardware, like a bunnch of PCIe4.0 NVMe SSDs [1].
Yep, the platform is 2 years old, but supports both the Zen2 and current Zen3 CPUs (but not PCIe5.0 & DDR5 as Zen 4 requires a different CPU socket and is only announced right now, not available from AMD until the end this month).
However, 8 x DDR4 channels and 128 x PCIe4.0 lanes still give you better total bandwidth than 2 x DDR5 and 24 x PCIe5.0 like the few currently available DDR5/PCIe5 platforms support.

- bick_nyers 4y agoThe unfortunate part is that Threadripper nowadays is OEM only, thus it is very expensive. You can just switch to EPYC with hardly any difference in price point.
- tanelpoder 4y agoThe Threadripper Pro 5000-series is available for retail purchases [1]. When 3000-series was launched, it was first OEM only (Lenovo) but later became available in retail too.

- bick_nyers 4y agoOh nice, I must have missed this. Motherboard prices are leaving something to be desired (lowest price is $900), but still, this is good news. Edit: On second glance, the markup compared to last-gen Threadripper is gnarly. 24 core SKU MSRP is $2.4k, compared to the 3000 series SKU which MSRP for $1.4k. At that point just go EPYC.
