If the rumors are accurate, we may see Rocket Lake-S desktop processors with eight cores and Xe GT1 integrated graphics. The mobile Rocket Lake-U is rumored to feature six cores in a 15W TDP, while Tiger Lake-U offers four cores at 15W. Then there's also a Tiger Lake-H that packs eight cores in a 45W TDP.
According to the details, the 12th Generation Core family would come in Rocket Lake-U 15W and Rocket Lake-S 35-125W flavors. The Rocket Lake-U family would feature up to 6 cores & 12 threads along with GT1 Xe graphics while Rocket Lake-H family would feature up to 8 cores and 16 threads with GT1 Xe graphics. Only Rocket Lake-U CPUs would come with SGX while both variants would support AVX2 / AVX-512 instructions. Rocket Lake-S would natively support DDR4-2933 MHz ram & Rocket Lake-U would support DDR4-2933 & LPDDR4X-3733 MHz memory. As per the leak, there won't be native but only discrete Thunderbolt 4 support, up to 20 PCIe Gen 4 lanes for the desktop and 4 PCIe Gen 4 lanes for the mobile family.Rocket Lake is 14nm while Tiger Lake is 10nm. So far, we haven't heard a lot of official information from Intel about these chips so take the rumors with a grain of salt.
