Alder Lake-S shows up in SiSoft Sandra, has DDR5 support

Once Intel has released its 14nm Rocket Lake-S series desktop processors, the focus will shift fast towards the next-gen processors series, Alder Lake-S, with its big-little design CPU cores.

Alder Lake-S already has been spotted in the benchmark database from SiSoft, SANDRA. While the numbers say very little, something else does, as the processor was listed using DDR5 RAM at 4800 MHz. It has been an ongoing rumor that Alder Lake-S supports both DDR4 and DDR5; this entry seems to confirm that thesis. Also, thumping is that the PC tested reports back 16 cores and 32 threads. Presumable these are 8 large (performance) Golden Cove cores with up to two threads per core paired with 8 small (energy friendly) Gracemont cores.

Thus, the listing indicates that the entire chip supports hyper-threading two threads per core, whereas the Golden Cove cores should have just a single thread. Presumably, that is a software error. This entry should see 24 threads available. The CPUs check-in at 30 MB of L3 cache and 10x 1.25 MB L2 cache. A base and boost clock speed of 1.8 GHz and 4.0 GHz are showing. The GPU of the chip uses the Xe 12.2 architecture that runs to a max of 1.5 GHz.
