Mystery Intel 12th-Gen Alder Lake-S 16C/32T CPU Leaked On SiSoftware Benchmark Website With Possible DDR5 And PCIe 5.0 Support?

Intel’s 11th-Gen Core Series CPUs, codenamed Lakefield, are the first one to sport the Hybrid Technology similar to the big.LITTLE Architecture of ARM processors. However, the company is already deep in the development of the 12th-Gen Processors, codenamed Alder Lake. A top-end variant of the Intel’s 12th Gen Core series has been spotted on the SiSoftware benchmark website.

Intel recently indicated its commitment to launching the 12th-Gen Alder Lake CPUs in the second half of 2021. A mystery Intel CPU, possibly belonging to the as-yet-unannounced family, has now surfaced online. The SiSoftware benchmark specifically identifies the processor, and the accompanying data strongly indicates Intel has already begun preliminary testing of the next generation of powerful processors.

Mystery Intel 12th-Gen Alder Lake-S CPU With 16 Cores And 32 Threads Appears On SiSoftware Benchmark Website:

A new set of benchmarks appeared on the SiSoftware database website. The listing claims the CPU being tested belongs to the Alder Lake family, and there are quite a few indicators as well. The CPU sports 16 Cores and 32 Threads, which correlates well with the maximum core count for Alder Lake-S. The CPU is reported to be packing 10x 1.25MB of L2 cache and 30MB of L3 cache. The L2 and L3 caches appear to be identical in size for Golden Cove and also for Willow Cove. The smaller Gracemont cores appear to be grouped with shared caches.

It is interesting to note that the benchmark mentions the testbench running with a DDR4 RAM module. The Alder Lake CPUs have been reported to support DDR5 RAM. However, the CPU being tested apparently belongs to the Mobility platform. This would also explain the rather low 1.38 GHz Base Clock. However, it is also possible that the low clock speed could be due to the CPU being an early-stage Engineering Sample (ES).

Mystery Intel 12th-Gen Alder Lake-S CPUs To Arrive In 2021?

Intel promised it will launch its hybrid big/small core architecture in the second half of 2021. The first Series of CPUs that would feature the big.LITTLE Architecture, was the Intel 11th-Gen Lakefield processors. This series packs the Sunny Cove and the Tremont Cores. While the Sunny Cove Core would be the Big or Power Core, the Tremont Cores would comprise the Efficiency Cores. According to previous reports, the Lakefield-S CPUs would have a single Sunny Cove Core paired with four Tremont Cores.

The Intel’s 12th-Gen Alder Lake CPUs, on the other hand, would comprise of the Golden Cove and Gracemont core architecture. While the Golden Cove Core would be the big or powerful core, the Gracemont core would be the efficiency core. The Alder Lake CPU’s layout, however, is quite balanced. According to previous reports, the 12th-Gen CPUs from Intel would have a total of 16 Cores equally divided between the Power Cores and Efficiency Cores.

The Alder Lake CPUs are rumored to benefit from Intel’s own hardware scheduler, which will reportedly take full advantage of the available computing cores. Moreover, the new generation of CPUs would also have much better and improved software support. As recently revealed, Intel is diving deep into the CPU Architecture to safeguard its CPUs from malicious code execution and middle-man attacks.
