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".
