Buona sera, devo assemblare il mio Pc, utilizzando una cpu di 11 generazione, che supportano PCI express 4.0, ma vedo che i Chipset Z490 3 Z590, dalle specifiche supportano il PCI express 3.0, secondo voi che chipset dovrei usare' Grazie.

That is correct; while the processor exposes PCIe 4.0 lanes, the chipsets only expose PCIe 3.0 lanes below them - and these are the lanes that typically get connected to M.2 connectors, thereby limiting SSD performance. This is a god-awful stupid design decision by Intel. I suspect that they punted on PCIe 4.0 support because the DMI bus is such a huge limitation (even at its doubled width with 5xx chipsets) anyway.
Off my soapbox now; probably preaching to the choir anyway...

Ciao, grazie.
Questo e un grande peccato, cosi si se ho ben capito si è limitati ad avere un Pc mezzo PCI 3.0 e PCI 4.0.
E da valutare anche l'acquisto di un ssd con fattore di forma M2, prenderlo con tecnologia PCI 4.0 potrebbe essere uno spreco.
Secondo te questo discorso e da fare anche sulla scheda video e sulle ram?
C'e anche il discorso, che si parla già di PCI 5.0 e PCI 6.0, in un piccolo futuro si potrebbe dire che un PC con gli ultimi Chipset che ci sono in questo momento, saranno sempre preformanti, ma vecchi riguardando l'evoluzione che ci sarà.
Ciao ciao, grazie.

Pensandoci bene, c'è anche da valutare che fare un PC con una Cpu di 11 generazione non sarebbe il caso, credo che bisognerebbe andare per una cpu di 10 generazione o aspettare che vengano fatti dei chipset che supportano il PCI express superiori.
Su questo avete notizie, non è che la scelta di Intel dei chipset attuali supportino il PCI 3.0, perché ci sono progetti per dei chipset che supportino il PCI 5.0 o PCI 6.0.

In some cases, it is possible to get better performance from a PCIe 4.0 M.2 SSD on a PCIe 3.0 system (PCH) than you get from a PCIe 3.0 M.2 SSD. This gain may not be substantial enough to rationalize the higher cost of the PCIe 4.0 SSD, but this can also be considered a level of future-proofing.
Intel processors come out the end of a very long, multi-year pipeline and what is important is less well known when some design decisions are made early on. The lack of responsiveness of this process is becoming more and more obvious as the seemingly more nimble AMD brings out its latest generations.
