Tipster @momomo_us has shared a SiSoftware database entry for an Alder Lake-S sample from Intel. The 12th Generation series, which is expected to be launched in the second half of this year, utilizes a hybrid microarchitecture that combines high-performance Golden Cove cores with energy-efficient Gracemont cores. This 16-core example is rumored to come with 8 of each cores but only the Golden Cove cores will be able to make use of SMT, leaving the Alder Lake-S processor with 24 threads for workflow (16x Golden Cove + 8x Gracemont).
However, this hybrid construction may be problematic for benchmark software, so the sample here is described as a 16-core, 32-thread part, which is likely incorrect. On top of that, the listing reveals the Alder Lake processor’s base clock of 1.80 GHz and a top-end figure of 4.0 GHz, although it has been speculated that these rates will be higher in the final products. Moving on through the SiSoftware listing, we see 10x 1.25 MB L2 cache for a total of 12.5 MB L2, followed by a whopping 30 MB L3 cache. In comparison, the Comet Lake i9-10900K has 20 MB L3 and the Rocket Lake i9-11900K has 16 MB L3.
As mentioned above, support for DDR5 RAM (UDIMM) is present and there is some information available about this 16-core Alder Lake-S processor’s iGPU. According to the record, the expected Iris Xe Gen 12.2 unit will have 256 shaders and 32 execution units, which aligns with a previous record spotted by noted leaker @_rogame. However, on that occasion the core clock was measured at 1.15 GHz whereas this latest sample has registered 1.5 GHz. Alder Lake is based on a 10 nm manufacturing process and will utilize the LGA 1700 socket.
