Intel H670, B660, et fuite des fonctionnalités du chipset H610

Intel is preparing to significantly expand its 12th Gen Core “Lac des Aulnes” desktop processor series next January, alongside more motherboard chipset choices for the client-desktop segment. These include the H670, the B660, and the H610. The H670 offers most of the I/O features of the top Z690 chipset, but you lose out on CPU overclocking. The B660 is the mid-tier option, and while you still get a formidable I/O feature-set, the chipset bus is narrower. The H610 is the entry-level chipset with very basic I/O, and no CPU-attached NVMe slots. The interesting thing is that all these chipsets support PCI-Express 5.0 x16 (CHEVILLE) from the CPU, but leave it to the motherboard vendors whether they want to implement it. There do exist Z690 motherboard that lack Gen 5 CHEVILLE (et uniquement fonctionnalité Gen 4).

Le PCIe en aval attaché au chipset varie également considérablement dans la gamme. La partie supérieure du Z690 sort 12 Gen 4 voies d'ailleurs 16 Gen 3 voies; tandis que le H670 émet 12 chacun des Gen 4 et Gén 3. Le B660 émet 6 Gen 4 voies et 8 Gen 3 voies. Le H610 manque complètement de génération en aval 4, et n'émet que 8 Gen 3 voies. Le H670 et le B660 émettent jusqu'à deux 20 Gbit/s USB 3.2 Gen 2×2 ports; alors que le H610 manque 20 Ports Gbit/s. Tous les modèles de chipset proposent au moins deux 10 Gbit/s Gen 2×1 ports; et au moins quatre 5 Gbit/s Gen 1×1 ports. Un aspect intéressant de la gamme est qu'Intel autorise l'overclocking de la mémoire sur les chipsets H670 et B660, à condition que le CPU le supporte.
