15/07/2021 12:00 PM Pacific Time Update: We have independently confirmed the specifications through our own sources. The configuration is accurate, however, the clock speed is for engineering samples (ES), so the final specifications will definitely be different.
A kind Know the forum users (by David Fries According to reports, the specifications of Intel’s upcoming 12th-generation products were published on Twitter Alder Lake K series processors. As with earlier leaked specifications, it is recommended to treat this information with caution.
The specifications of ordinary desktop processors are very simple, because all cores follow the same specifications Clock speedBut for Alder Lake, Intel introduced a hybrid design; this means that people need to digest more information.You must view the specifications of the high-performance Golden Cove separately CPU core And the more energy-efficient Gracemont kernel.
In today’s revelations, Zhihu users shared the so-called specifications of the overclocked unlocked models Core i9-12900K, Core i7-12700K and Core i5-12600K. Obviously, these three K series chips have the same power level. PL1 (power level 1) is an index publicly promoted by Intel, with a rated power of 125W. This is not as surprising as the past K series chips, including Rocket Lake and Comet Lake also have 125W PL1 ratings.
It seems that the real improvement lies in PL2 (power level 2), which corresponds to the maximum power consumption when turbocharging is in effect. For comparison, Core i9-11900K with Core i7-11700K The Rocket Lake chip is fixed at 250W PL2. Allegedly, their Alder Lake equivalent power dropped to 228W, a drop of only 8.8%.
Intel 12th Generation Alder Lake Specifications
|processor||Golden Cove / Gracemont Cores||Golden Cove 1-2C / 8C boost (GHz)||Gracemont 1-4C / 8C boost (GHz)||Level 3 cache (MB)||PL1 (wide)||PL2 (wide)|
|Core i9-12900K||8/8||5.3 / 5.0||3.9 / 3.7||30||125||228|
|Core i7-12700K||8/4||5.0 / 4.7||3.8 / 3.6||25||125||228|
|Core i5-12600K||6/4||4.9 / 4.5||3.6 / 3.4||20||125||228|
Core i9-12900K will lead Intel’s 12th generation charging and will replace Core i9-11900K. Naturally, Core i7-11700K with Core i5-11600K Hand the baton to the Core i7-12700K and Core i5-12600K respectively. In terms of the number of cores, Alder Lake will be similar to Rocket Lake in terms of large cores. However, Alder Lake has added Gracemont cores, which may make heterogeneous processors look good on paper for those who calculate the total number of cores.
The Core i9-12900K has 16 cores, and there are 8 Golden Cove cores and 8 Gracemont cores in the configuration. The Core i9-12900K has 30MB of L3 cache onboard. The Golden Cove core has a 5.3 GHz dual-core boost clock and a 5 GHz full-core boost clock. On the other hand, the Gracemont core has a 3.9 GHz quad-core boost clock and a 3.7 GHz full-core boost clock.
The Core i7-12700K has four fewer Gracemont cores than the Core i9-12900K. The leak points to 12 total cores and 25MB L3 cache in an 8+4 setting. The dual-core and full-core boost clock speeds of the Golden Cove core are 5 GHz and 4.7 GHz, respectively. As for the Gracemont cores, they run with a 3.8 GHz dual-core boost clock and a 3.6 GHz full-core boost clock.
Core i5-12600K is equipped with 10 cores, adopts 6+4 configuration, and is supplemented by 20MB L3 cache. The Golden Cove core is equipped with 4.9 GHz dual-core and 4.6 GHz six-core accelerated clock speed, while the Gracemont core is limited to 3.6 GHz dual-core accelerated clock and 3.4 GHz quad-core accelerated clock.
The approximate time span of Alder Lake’s debut is from the end of 2021 to the beginning of 2022. We will soon know whether Intel’s courageous bet on hybrid desktop chips will pay off.
