The first specs of Intel’s Alder Lake desktop processor line, including the Core i9-12900K, have leaked onto the net.
The rumors essentially concern the K series (with unlocked multiplier) intended for motherboards with Z690 chipset and LGA1700 socket, which will offer full support for overclocking.
That the time of Alder Lake is almost here is testified by the fact that in the last few days several ES CPUs (Engineering Sample) have started to run among some “selected” users which, however, are not representative of what the specifications and performance will be. final, to which are added the guidelines that Intel is providing regarding its partners.
Alder Lake will therefore be Intel’s first mainstream desktop processor based on the new 10nm SuperFin manufacturing process, a “hybrid” chip that combines larger “Golden Cove” or P-core and smaller “Gracemont” or E- cores. core in a similar way to ARM’s big.LITTLE architecture or big.SMALL, to offer high performance with significantly improved energy efficiency.
The flagship model of the 12th generation Alder Lake desktop CPU line will be the Core i9-12900K, which will integrate 8 Golden Cove cores and 8 Gracemont cores for a total of 16 cores (8 + 8) and 24 threads (16 + 8).
The P-cores (Golden Cove) will run at a maximum boost frequency of 5.3GHz with 1-2 active cores and 5.0GHz with all cores active, while the E-cores (Gracemont) will run at 3.90GHz on 1 -4 cores and up to 3.7GHz when all cores are called into question.
The CPU will be equipped with 30MB of L3 cache with TDP values of 125W (PL1) and 228W (PL2).
Turning to Core i7-12700K, Intel will offer 8 Golden Cove cores, but will reduce Gracemont cores to 4, which will result in a total of 16 cores (8 + 4) and 20 threads (16 + 4).
The P-cores (Golden Cove) will run at a maximum boost frequency of 5.0GHz with 1-2 active cores and 4.7GHz with all cores active, while the E-cores (Gracemont) will run at 3.8GHz on 1 -4 cores and up to 3.6GHz in case they are all used.
The CPU will be equipped with 25MB of L3 cache with the same TDP values as the top-of-the-range solution.
Finally, we have Intel Core i5-12600K which will be the entry-level unlocked chip within the new offering, as there is no “K” version planned for the i3s.
This model will be equipped with 6 Golden Cove and 4 Gracemont cores for a total of 10 cores (6 + 4) and 16 threads (12 + 4).
The P-cores (Golden Cove) will run at a maximum boost frequency of 4.9GHz with 1-2 active cores and 4.5GHz with all cores active, while the E-cores (Gracemont) will run at 3.6GHz on 1 -4 cores and up to 3.4GHz with all cores used.
The CPU will be equipped with 20MB of L3 cache and TDP values are maintained at 125W (PL1) and 228W (PL2).
Intel Alder Lake Desktop CPUs are expected to launch in Q4 2021 and will be part of the first mainstream consumer platform to use PCIe 5.0 and DDR5 technologies, along with a new hybrid architecture approach that Microsoft has optimized for its Windows operating system. 11.
