Was bringt PCI-Express 2.0 ?

[DI°G]

Hallo verehrte Gemeinde,

habe ein mittelprächtiges Asus M2V board (Sockel AM2), CPU ist Athlon 64X2 6000+

Der PCI-E Standard ist 1.0

Lohnt es sich für den PCI 2.0 Standard, den die Grafikkarte unterstützt, ein neues board anzuschaffen 

Freue mich über fachkundige Ratschläge.

Gruß,

Nein --> z.Z. wird das mehr an Bandbreite noch (!!) nicht genutzt und - wenn sich alle an die Vorgaben der Spezifikationen halten - sind alle PCIe-Standards sind untereinander voll kompatibel:

Q4: It sounds as if both speed grades are supported in the PCIe 2.0 specification?
A4: The PCIe Base 2.0 specification supports both 2.5GT/s and 5GT/s signaling rates, in order to retain backward compatibility with existing PCIe 1.0 and 1.1 systems. Aside from the faster bit rate, there are a number of improvements in this new specification that allow greater flexibility and reliability in designing PCIe links. For example, the interconnect can be dynamically managed for platform power and performance considerations through software controls. Another significant RAS feature is the inclusion of new controls to allow a PCIe link to continue to function even when some lanes become non-operational.

Q5: Then PCIe 2.0 must be backward compatible with PCIe 1.1 and 1.0?
A5: Yes. The PCIe Base 2.0 specification supports both the 2.5GT/s and 5GT/s signaling technologies. A device designed to the PCIe Base 2.0 specification may support 2.5GT/s, 5GT/s or both. However, a device designed to operate specifically at 5GT/s must also support 2.5GT/s signaling. The PCIe Base specification covers chip-to-chip topologies on the system board. For I/O extensibility across PCIe connectors, the Card Electromechanical (CEM) and ExpressModuleâ„¢ specifications will also need to be updated, but this work will not impact mechanical compatibility of the slots, cards or modules. Currently, the PCI-SIG is defining the PCIe CEM 2.0 specification which has been released to members for review at v0.5. There are currently no plans to adapt the PCIe Mini CEM specification for the faster bit rate as the market need has not yet materialized.

Gracias, Faust !

ist mit Deiner Antwort wohl hinreichend geklärt.

Irgendwie steh' ich auch auf kurze Themen
