The latest database of the SiSoftware SANDRA benchmark TUM_APISAK has spotted the latest entry of the flagship in the Intel Alder Lake, the Core i9-12900K Desktop CPU. This latest leak offers much higher clock speeds & inter-thread efficiency performance.
As we know already, the Core i9-12900K will be the flagship chip within the 12th Gen Alder Lake Desktop CPU line, and the latest benchmark details offer details about the processor with various clock speeds that might be the boost clocks for both, the P-Core (Golden Cove) and E-Core (Gracemont).
Intel’s Core i9-12900K Alder Lake-S CPU will feature 16 cores and 24 threads, and going into detail; it will be arranged in 8 P-Core (with 16 threads) and 8 E-Core (with 8 threads). The Core i9-12900K will also be featuring 30 MB of L3 cache, which is arranged in 3 MB per core partition on the P-Core (Golden Cove) and 3 MB per cluster on the E-Core (Gracemont).
The clock speeds of the Intel Core i9-12900K will feature a P-Core base and boost clocks of 3.2 GHz / 5.3 GHz, and its E-Core will have base clocks of 3.0 GHz and boost clocks of 3.9 GHz. However, these are only for single cores.
On the other hand, the all-core boost frequencies are expected to be 5.0 GHz for the P-Core and 3.7 GHz for the E-Core.
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 (PL1) | TDP (PL2) | Price |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Intel Core i9-12900K | 8 | 8 | 16 / 24 | 3.2 / 5.3 GHz | 5.0 GHz (All Core) | TBA / 3.9 GHz | 3.7 GHz (All Core) | 30 MB | 125W | 228W | $599 US |
| Core i9-12900 | 8 | 8 | 16 / 24 | TBA / 5.3 GHz | 5.0 GHz (All Core) | TBA / 3.9 GHz | 3.7 GHz (All Core) | 20 MB | 65W | ~200W | $509 US |
| Intel Core i7-12700K | 8 | 4 | 12 / 20 | 3.6 / 5.0 GHz | 4.7 GHz (All Core) | TBA / 3.8 GHz | 3.6 GHz (All Core) | 25 MB | 125W | 228W | $429 US |
| Core i7-12700 | 8 | 4 | 12 / 20 | TBA / 5.0 GHz | 4.7 GHz (All Core) | TBA / 3.8 GHz | 3.6 GHz (All Core) | 25 MB | 65W | ~200W | $359 US |
| Intel Core i5-12600K | 6 | 4 | 10 / 16 | 3.7 / 4.9 GHz | 4.5 GHz (All Core) | TBA / 3.6 GHz | 3.4 GHz (All Core) | 20 MB | 125W | 228W | $279 US |
| Core i5-12600 | 6 | 0 | 6 / 12 | TBA | TBA | TBA | TBA | 18 MB | 65W | ~200W | $249 US |
| Core i5-12400 | 6 | 0 | 6 / 12 | TBA | TBA | TBA | TBA | 18 MB | 65W | ~200W | $203 US |
However, the SiSoftware Sandra benchmark could not get the exact power figures; hence the standard 125W (PL1) TDP is mentioned in the above table. Coming to the Inter-Thread efficiency, a benchmark that measures the efficiency of inter-thread, core, module, node, & inter-package communication fabrics, the CPU managed to score an average of 112.30 GB/s.
The Intel Alder Lake CPUs are expected to launch in November, announced by the end of October.
