Wenn ich PCI 4.0 bräuchte, würde ich mich derzeit nicht darauf verlassen. Es sei denn, ein MB-Hersteller garantiert mir das.
Ich weiß nicht recht ob das gut ist. Ich denke, dass sich AMD was dabei gedacht hat, als man meldete PCIe 4.0 nur mit dem Chipsatz X570 zu unterstützen. Na man wird ja sehen ob das Ganze funktioniert.
Why AMD X570 Costs So Much hat gesagt. :
- Keep in mind that a lot of the sticker shock from a $700 Xtreme or $777 Godlike is just because manufacturers are now moving premium brands over from their Intel lines, which is new for AMD
- Chipset cost is about 2x what it was for X470
- PCIe Gen4 required redesigns and rerouting of traces, driving up cost
- Signal integrity becomes a challenge on some boards, and so extra time is needed for validation or higher quality PCB materials are needed
Wobei das B450/X470 Mainboard BIOS-Flashback und ein 32MB BIOS haben muss/sollte, so wie AGESA Code 1.0.0.6 und AMD ComboPI1.0.0.3a.The persistence of AMD’s AM4 socket, still slated for life through 2020, means that new CPUs are compatible with older chipsets (provided the motherboard makers update BIOS for detection). It also means that older CPUs (like the reduced price R5 2600X) are compatible with new motherboards, if you for some reason ended up with that combination. The only real downside, aside from potential cost of the latter option, is that new CPUs on old motherboards will mean no PCIe Gen4 support. AMD is disabling it in AGESA at launch, and unless a motherboard manufacturers finds the binary switch to flip in AGESA, it’ll be off for good. Realistically, this isn’t all that relevant: Most users will never touch the bandwidth of Gen4 for this round of products (in the future, maybe), and so the loss of running a new CPU on an old motherboard may be outweighed by the cost savings of keeping an already known-good board, provided the VRM is sufficient.
