The core configurations for Intel’s 12th Gen Alder Lake-S CPUs has been leaked, courtesy of a GitHub file on Corebook. As per the leak, Alder Lake will feature as many as sixteen cores on the desktop platform with the LGA1700 socket. Similar to the recently launched Lakefield SoC, half of these will be the low-power “Little” Goldmont/Gracemont cores while the remaining will be the high-performance “Big” Golden Cove cores.
As you can see, there are several different core configurations for Alder Lake and it’s likely that not all of them will make the cut. There will be CPUs with 8 HP cores with 0 to 8 LP cores (Core i7s and i9s). Similarly, there appear to be hex-core parts with 0 to 8 low-performance cores (Core i5s). Finally, the quad-core i3s feature just four high-performance cores. There’s also a dual-core part but I believe that’s the Celeron/Pentium model.
On the iGPU side, while all the Alder Lake-S CPUs will feature an Xe GPU, they’ll all be limited to the lower-end GT1 variant. Only the Alder Lake-P chips will include the higher-end GT2 integrated graphics.
Intel’s 12th Gen Alder Lake-S processors leveraging the Big.Little design are expected to launch in late 2021. They’ll be the first desktop lineup from Team Blue to be fabbed on the 10nm node.
