On this page, you can observe the Core i9 12900K. Socket LGA1700 with that number meaning the number of pins means quite a bit of pin contact points right there. We use Z690 motherboards with the latest motherboard BIOS revisions. 



The Intel Core i9 12900K and Core i5 12600K processors came in a nice press package from Intel holding a 12900K as well as 12600K. Each processor will be reviewed in its own article.




The core i9-12900K is composed of 16 core components, 8 Golden Cove, and 8 Gracemont core components. There is 30MB L3 cache available in the Alder Lake flagship SKU. The Core i9-12900K offers an unlocked overclocking multiplier. It's a K-series SKU. 


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. 

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.



Our Alder Lake and Z690 based reviews will use memory kits from Corsair (Dominator) and G.Skill (Ripjaws S5). Both kits are rated 5200 MHz at either CL38 or CL40 and consist of a dual-channel 32GB configuration. This review will be using the G.Skill kit. 


G.SKILL Ripjaws S5 DDR5 memory series is engineered with high-quality hand-screened ICs, designed for high-speed performance, and tested for compatibility across a wide range of DDR5-enabled motherboards. At launch, Ripjaws S5 is available up to DDR5-6000 memory speed, making this the nice choice for experiencing high-performance bandwidth of next-gen DDR5 memory.
