Currently, the specifications for Intel Core i9-12900K are known, but we don’t have much information on the non-K variant like the reduced TDP to 65W(the K-series has 125W). Luckily an engineer at ASUS’s HQ forgot to unplug a benchmark system from the Internet.
It looks like the CPU was benchmarked on UserBenchmark(UB), where a Taiwanese tested the CPU through a flagship DDR5-memory based platform user, ASUS ROG Maximus Z690 Extreme motherboard.
It is worth noting that it is not a full benchmark. The system’s attachment to a 1280×1024 monitor confirms that it is a testing system. Moreover, only one slot of the motherboard is occupied with Crucial DDR5-4800 memory (C8C1084S1UC48BAW). This alone may cause a bottleneck.
As per UB, the CPU will have a base clock speed of 2.4 GHz and a turbo boost of up to 4.25 GHz. The former might refer to Efficient (small) core specs, while the latter is probably Performance core’s boost. The CPU will have the same hybrid configuration as the K-series model, 8 E-Cores + 8 P-Cores and 24 threads.
As far as the scores are concerned, the i9-12900 scored 241 points in single-core score points, 2510 points in the multithreaded test, and 114% UB overall ranking.
In other news, a photo of the Core i9-12900KF model has also leaked. This CPU is an entering sample carrying QY5U code, which is a qualification sample of the KF 12900 model. This CPU is unlocked (125W) but lacks integrated Xe graphics.
