The day of the introduction of Intel Alder Lake is approaching, test results in the rumor mill are increasing. The CPU series is getting a little better every day. The latest tests claim that the Core i9-12900K as the flagship desktop beats the AMD Ryzen 9 5950X in both single and multi-core use – in Geekbench.

Single-core strong, but probably still with problems

Geekbench 5 is Intel's processors. Rocket Lake-S, alias the 11th generation core in the desktop PC, ranks at the top of single-core performance thanks to its high clock rate, which is not per se the case in many other applications. In this respect, Alder Lake-S could be represented a little too well in Geekbench than it is in the end compared to AMD Zen 3.

What Geekbench allows better is the comparison at Intel. Alder Lake-S beats Rocket Lake-S there, albeit only very slightly in the lower single-digit percentage range. From this perspective, the result is less good than expected, after all, the average IPC of the performance cores from Alder Lake should increase by 19 percent compared to Rocket Lake – that is definitely not visible here and could still indicate problems with the scheduler or too low Indicate clock rates.

multi-core with exclamation marks

The multi-core result does not indicate a problem, here Alder Lake-S in the form of the Core i9-12900K ranks almost 60 percent ahead of the Core i9-11900K, the additional eight small cores are obviously used here.

Compared to the competitor AMD, these results also look good: The fact that the eight large and eight small cores can beat AMD's flagship in the multi-core environment can now be seen for the first time in a leak. The exact test conditions are not known, for example, the boost clock is read completely incorrectly, so there is scope for false reports. Nonetheless, the results fit into the overall picture, which manifested itself last and is underpinned today in further tests.

Yesterday, results for the Intel Core i7-12700 appeared, a 65-watt solution, recognizable by the lower base clock. This solution is just on the heels of the AMD Ryzen 7 5800X in the higher TDP class of 105 watts.

At the same time, there are also sightings of Alder Lake in the notebook. 8 cores and 12 threads will be offered in the upcoming Asus VivoBook, which suggests the smaller mobile CPU die, which consists of six performance cores with Hyper-Threading and eight small cores and can then be configured differently.

Intel Alder Lake is expected almost parallel to the launch of Windows 11 at the end of October/beginning of November this year. Because, according to Intel, the operating system is a prerequisite for optimal operation because the new Intel hardware scheduler is designed for it. The editors have already stated several times that Alder Lake-S should stand or fall with this thread director and the implementation in the operating system.
