In the recent entry of UserBenchmark Database, an alleged entry of the Intel’s Alder Lake-S based Core i9-12900K CPU has been discovered and this CPU was spotted running on a desktop platform. There was no name discovered for the CPU, however, looking at its specifications, the card which we are looking at is Intel’s Core i9-12900K (12900) SKU.
This CPU that appeared on UserBenchmark featured 16 cores of which 8 are based on the Golden Cove and 8 are based on the Goldmont architecture. This gives the CPU a total of 24 threads out of which 16 threads are from performance cores and 8 threads from efficiency cores. In terms of clock speed, this particular model has a 1.80 GHz base clock and a 3.65 GHz boost frequency clock.
These are the rumoured specs of the Alder Lake lineup:
Intel 12th Gen Alder Lake Desktop CPU Specs “Rumored”
| CPU Name | P-Core Count | E-Core Count | Total Core / Thread | P-Core Base / Boost (Max) | P-Core Boost (All-Core) | E-Core Base / Boost | E-Core Boost (All-Core) | Cache | TDP | Price |
| Intel Core i9-12900K | 8 | 8 | 16 / 24 | TBA / 5.3 GHz | 5.0 GHz (All Core) | TBA / 3.9 GHz | 3.7 GHz (All Core) | 30 MB | 125W (PL1) 228W (PL2) | TBA |
| Intel Core i7-12700K | 8 | 4 | 16 / 20 | TBA / 5.0 GHz | 4.7 GHz (All Core) | TBA / 3.8 GHz | 3.6 GHz (All Core) | 25 MB | 125W (PL1) 228W (PL2) | TBA |
| Intel Core i5-12600K | 6 | 4 | 12 / 16 | TBA / 4.9 GHz | 4.5 GHz (All Core) | TBA / 3.6 GHz | 3.4 GHz (All Core) | 20 MB | 125W (PL1) 228W (PL2) | TBA |
Following is what the core configuration of all Alder Lake CPUs is rumoured to look like:
- Intel Core i9 K-Series (8 Golden + 8 Grace) = 16 Cores / 24 Threads
- Intel Core i7 K-Series (8 Golden + 4 Grace) = 12 Cores / 20 Threads
- Intel Core i5 K-Series (6 Golden + 4 Grace) = 10 Cores / 16 Threads
- Intel Core i9 A-Series (8 Golden + 8 Grace) = 16 Cores / 24 Threads
- Intel Core i7 A-Series (8 Golden + 4 Grace) = 12 Cores / 20 Threads
- Intel Core i5 A-Series (6 Golden + 0 Grace) = 6 Cores / 12 Threads
- Intel Core i3 A-Series (4 Golden + 0 Grace) = 4 Cores / 8 Threads
Coming to the System on which the CPU was tested was the HP OMEN 45L desktop platform that comprised of 16 GB DDR4-3200 memory. This is just a preliminary test board and not a proper Z690 motherboard which is expected to launch in Q4 2021.
