If we are to believe news from Intel, new series of processors based on Alder Lake architecture are about to be released somewhere in October. Alder Lake is the 12^th Generation Core of Intel processors and it is meant to have all advantages of the current CPU structure. I9 is aimed to pack a punch against its competitors with technology including eight high-performance Golden Cove cores (P-cores) with Hyper-Threading and eight energy-efficient Goldmont (E-cores) equipped with a 30MB L3 cache and operating at high clock speeds. During the benchmark test, the new CPU outperformed all of Intel’s previous Rocket Lake structure processors which is logically expected but the big surprise came from results that indicate better performance than Apple’s new M1 processor even in single-threaded performance which is supposed to be best in that field. Another surprise was really beating AMD Ryzen 9 in each field. If we take into account that i9 has 16 cores in total and can process 24 threads against Ryzen 9 with 16 Cores and 32 threads this is an impressive feature. Now truth to be told Alder lake has massive L3 cache and microarchitectural advantages and consumes much more power but the results of performance are high. Also, note that this early CPU is not really a mass production one and maybe some things will still change but early results are very satisfactory. We will see what will price tag be since in this age of shortage and competition that will also play a big role in its overall success. Speaking of competition I eagerly await AMD’s response to this, in any way it seems that the CPU market is for some turbulence which is always a good thing for the final customer and I welcome it.
