Intel Core i9-12900K, i7-12700K and i5-12600K Alder Lake-S Desktop Proc Specs leak

Late this year Intel will reveal its BIG-little-based processor, energy-friendly cores, and power full ones. The Desktop processors are developed under the codename Alder Lake-S.

The new Hybrid CPU fits into an LGA1700 socket and is tied to the 600-series chipset. The 10-nm "Alder Lake-S" silicone has up to eight "Golden Cove" performance core cores (P-cores), and up to eight "Gracemont" efficiency cores (E-cores). LITTLE. Specs now have surfaced on online Chinese media and social channels.

The flagship will (not surprisingly) be called Core i9-12900K in the 12th Gen Core lineup series, and will succeed the i9-11900K with the maximum configuration of 8+8 (P+E), unlocked multipliers, the highest cache, and the fastest clock speed. The P (performance) core ("Golden Cove" core) is clocked at 5.30 GHz and the all-core core is clocked at 5.00 GHz / 8 cores. Its gracemont core (energy efficient) is clocked at 3.90 GHz (1 to 4 cores boost) with the all-core boot of 3.70 GHz / 8 cores. The silicon's total L3 cache is 30 MB. The TDP is 125 W for the i9-12900K (PL1) and 228 W PL2 for this product. Intel is introducing numerous new overclocking capabilities, including memory gear ratios.

The 12th gen core i7 is configured as 8+4 core (P+E), has somewhat lower clock rates than the i9 core, and some boost functions may be missing. The Core i7-12700K is the highest geared Core i7. The highest P-core boost frequency is 5.00 GHz and the all-core booster is 4.70 GHz, while the top boost for E-cores is 3.80 GHz with an all-core of 3.60. The chip contains 25 MB of L3 and is similar to the i9-12900K for PL1 and PL2 values.

Up to 6+4 core (P+E) cores are supplied for the Core i5 series. The unlocked Core i5-12600K operates the P-cores to 4.90 GHz with an all Core of up to 4.50 GHz, while the E-cores are up to 3.60 GHz with an entire Core of up to 3.40 GHz. 20 MB of L3 cache, and the same 125 W PL1 and 228 W PL2 values as the other two unlocked parts.
