Intel's Alder Lake big.LITTLE CPU design, tested: It's a barn burner:

After spending several days with Intel's newest consumer CPU designs, we have some surprising news: they're faster than AMD's latest Ryzens on both single-threaded and most multithreaded benchmarks.

We suspect this will be especially surprising to some, since Intel's newest desktop CPUs feature a hybrid "big.little[sic]" design similar to those found in ARM CPUs. AMD's flagship Ryzen 9 5950x is a traditional 16 core, 32 thread design, with all cores being "big" high-performance types with symmetric multithreading (SMT, also known as "hyperthreading"). By contrast, the i9-12900K offers 16 cores and only 24 threads—with eight "performance" cores featuring SMT and eight lower-performance "efficiency" cores with no SMT.

As pointed out in the Ars Technica comments, the Cinebench multi-threaded benchmark saw Intel's best CPU with a less than 2.5% lead, but the caption reads "Intel trounces AMD". While the Passmark multi-threaded benchmark saw AMD's best CPU with a more than 18% lead, but the caption reads "outperform i9-12900k-but even here, by a much, much, lower margin than we're accustomed to seeing".

    big.LITTLE and DynamIQ are not the same thing. They are both heterogeneous computing architectures and have some similarities, but they are not identical nor are they compatible. I think another reason they switched is because they got the heterogeneous computing mind share of most people first and "big.LITTLE" is starting to suffer from trademark erosion due to the "Kleenex" problem of being used generically.
