While Rocket Lake processors were expected to be backward compatible, news came upsetting users of B460 and H410 chipsets. The reasons behind the firm’s decision have been revealed.

Blue team will offer IPC growth years later, with Rocket Lake processors that will feature Cypress Cove cores.

Naturally, users are very excited about waiting for Rocket Lake with its 400 series motherboard. Unfortunately, not every 400 series chipset will be able to meet current processors.

Although the B460 and H410 chipsets, which became official with the table published by Intel, will not be offered Rocket Lake, the reasons behind the company’s decision are not entirely due to commercial concerns.

Lack of support is due to insufficiency
The B460 / H410 chipsets, which Intel has renamed some of its older chips and are out of the 22 nm process, are limited to the older Management Engine version, and cannot transmit the PMSYNC / PMDN signals required to work with Rocket Lake-S processors over sidebands.

Intel previously renamed the H170 chipsets to B365. However, the reason that prompted the company to rename during this period was the failure of 14 nm production capacity to keep up with demand.

H410 motherboards with H470 chipsets
On the other hand, some manufacturers such as Gigabyte have found the problem in developing motherboards based on the H470 chipset, which goes through the 14 nm process, although it is more costly.

The H410M DS2V V2 and H410M S2H V2 models are based on a more recent chip than the early versions. The new motherboards, which are expected to be offered at a more affordable price than the current motherboards, can be a good option for those who will install a budget-oriented Rocket Lake system.
