According to the latest reports from China, the transition from DDR4 and DDR5 will take longer than expected. Intel’s Alder Lake processors, the first consumer CPUs to support the next-gen memory are slated to launch early next month. However, according to industry sources, most users will want to stick to the DDR4 supported motherboards.
The reasons are multiple. Firstly, the Alder Lake processors paired with DDR5-5400 (and below) won’t really have an appreciable advantage over their DDR4 counterparts. Only faster modules (DDR5-6400 and above) will make a notable difference in the end performance, and these are going to cost a pretty penny. Furthermore, since the memory latency of initial DDR5 kits will be fairly high (CL35+), the gaming performance might just be lower than the DDR4 paired SKUs (if not identical).
In addition to this, Windows 11 is being recommended as a must for consumers upgrading to the Alder Lake platform. The reason being that support for hybrid core scheduling is presently missing on Windows 10 and could take a while to be patched in.
Finally, while it’ll be possible to disable the efficiency cores (Gracemont), the performance (Golden Cove) cores will remain enabled at all times. You won’t be able to turn off the latter using conventional methods.
