Intel 12th Gen i5, i7, and i9 Alder Lake Specifications Leak

Intel's 12th Generation Alder Lake processors are due to launch later this year, offering desktop customers their first look at Intel's hybrid x86 Core Architecture. 

Golden Cove is unique amongst Intel processors for offering a combination of High Performance (P-Core) Golden Cove CPU cores and High Efficiency (E-Core) Gracemont CPU cores, a factor that should allow Intel to deliver increased performance/watt characteristics for the company's newest processors. 

Thanks to La Frite David on Twitter, who cited the Chinese website Zhihu, we have our first look at leaked Intel Alder Lake specifications, which highlight the core configurations and core clock speeds of the company's 12th Generation Alder Lake Core i5-12600K, Core i7-12700K and Core i9-12900K processors. 

Core i9-12900K

Like prior rumours have suggested, Intel's i9-12900K will feature eight high-performance Golden Cove CPU cores and eight high-efficiency Gracemont CPU cores. This gives Intel's i9-12900K sixteen CPU cores in total, though each set of CPU cores will have different performance characteristics. 

Intel's eight high-performance cores will reportedly feature 1-2 core Boost clock speeds of 5.3GHz and an all-core boost clock speed of 5.0GHz, while Intel's efficiency-focused cores will feature lower 1-4 core boost clock speeds of 3.9GHz and an all-core boost of up to 3.7GHz. 

Based on Intel's leaked specifications, Intel's i9-12900K will feature 30MB of L3 cache. Based on the leaked specifications of Intel's other Alder Lake processors, Intel is offering 2.5MB of L3 cache per Golden Cove (High-Performance) CPU core and 1.25MB of L3 cache per Gracemont (High Efficiency) CPU core.

Core i7-12700K

Intel's next-gen i7 will reportedly focus on high-performance core performance, offering users eight high-performance cores and four high-efficiency cores. Intel's high-performance Golden Cove cores will reportedly boost to 5.0GHz on 1-2 cores and feature an all-core (8-core) boost of 4.7GHz. With the CPU's four E-Cores, a 1-2 Core boost clock speed of 3.8GHz will be available alongside a 3.4GHz 4-core boost. 

This processor will feature 25MB of L3 Cache, matching the core/cache configuration of the i9 above.

Core i5-12600K 
 
With six high-performance Golden Cove cores and four high-efficiency Gracemont cores, the i5-12600K will offer moderately lower clock speeds than the i7 model and two fewer high-performance cores. 

Like the three unlocked K-series CPUs above, the i5-12600K has a PL1 TDP of 125W and a PL2 TDP of up to 228W. This i5 model will feature 20MB of L3 cache, which is more cache than today's i9-11900K (which features 16MB of L3 Cache). 

  

Intel 12th Gen i5, i7, and i9 Alder Lake Specifications Leak  
Intel's Alder Lake lineup will deliver a tonne of new features to Intel's K-series product stack, especially with regards to overclocking. New memory ratios will be available for fine-tuning, and per-core overclocking will become more important than ever, thanks to Intel's hybrid CPU designs.

Windows 11 should also prove to be a vital component of Intel's Alder Lake push, as Microsoft's latest OS is designed with hybrid x86 CPUs in mind. This should allow Intel's hybrid CPU architecture to suffer from fewer performance issues when compared to their earlier, now discontinued, Hybrid Lakefield processors.

Any node info? High efficiency stuff aside, these sound like they're going to run hot.
Also, my concern with these hybrid CPUs is that even today, certain background processes can seriously hamper a full fledged multi-core system, let alone ones with high efficiency, and I guess lower performance cores.Quote

Alder Lake is 10nm. A lot of Alder Lake's success will be defined by how well Windows 11 handles it. I think Windows 10 users will have less performance.Quote

Fair enough on the node. 14nm would have been hilarious to see.

I can't imagine this scheduler having that much difference though, probably 5% at best.Quote

It can make quite a difference. If it doesn't manage any threads, everthing would become single thread bound, the smaller cores would never get used, it would constantly be replacing cache increasing latency, and thats not including the battery gains they could make where Alder Lake will be more aimed towards.

They've already shown quite significant improvements in the leak build for Alder Lake. Using a Galaxy Book S they got 5.8% more in GeekBench and 10% more in browsing. This is for a device that was never built for this OS and with really no drivers available. They could very well increase that performance further, not to mention better battery management.Quote
