In the second half of 2021, Intel promises to introduce both mobile and desktop Alder Lake processors with an unusual configuration of computing cores, so their engineering samples are starting to be increasingly found in various synthetic benchmarks. A new example of this kind was found in the Geekbench 4 database.
Earlier we saw a sample of the mobile variant of Alder Lake-P, equipped with 14 processing cores and supporting 20 simultaneous processing of threads. This time, the Alder Lake-S desktop model with 16 cores and 24 threads came into view. This strange configuration of the 12th Gen Intel Core chips is due to the fact that they use a hybrid arrangement of large high-performance and small energy-efficient cores. In the latter case, the chip has 8 large and 8 small cores. At the same time, only the first eight supports multithreading, therefore, in total, the processor is capable of processing up to 24 threads.
The unusual architecture of new Intel chips affects the behavior of tests when working with them. At least for now. If the base frequency of the engineering sample Alder Lake-S Geekbench 4 could still be calculated by giving a value of 2.2 GHz, then a rather comical situation came out with reading the Turbo frequency – the test showed a value of 27.2 GHz, which of course does not reflect the real picture. By the way, with the above-mentioned mobile Alder Lake-P sample, everything turned out much better. Then a more recent version of Geekbench 5 reported that the Turbo frequency of the chip is 4.7 GHz.
An equally interesting fact is that the engineering sample of Alder Lake-S was tested on a system with 32 GB of new DDR5 RAM, a massive transition to which is expected next year. It will work not only with upcoming 12th Gen Intel Core chips, but also upcoming AMD processors based on the Zen 4 architecture. In both cases, the chips are also credited with support for the new PCIe 5.0 interface.
In a single-threaded Geekbench 4 test, the desktop Alder Lake-S sample scored 6,536 points, in a multi-threaded one – 47,870 points. At this level of performance, it is already competitive with some of the AMD Ryzen 5000 family of chips. On the other hand, an early engineering sample of the processor took part in the test, so there is probably still a lot of room for improvement.
