So we have an update from our sources and it looks like Alder Lake is going to be one of the most exciting transitions in the PC industry for quite some time. A lot of the info we have will act as confirmation of past leaks and there is also some new info: we know when Intel is planning to launch its Alder Lake CPUs.

Know how AMD blindsided Intel with the introduction of PCIe 4.0 and how for the longest time Intel did not have a PCIe 4.0 to compete with Ryzen? Well, looks like team blue is taking a leaf out of red's book because the company is planning to be first to market with PCIe 5.0 and DDR5. These past few weeks Intel has been briefing partners about the Alder Lake launch and while PCIe 5.0 should be supported universally, not all boards might get the DDR5 option.
