Research indicates that Intel’s forthcoming Core i9-15900K CPU has appeared on Geekbench 6.4. The upcoming next-gen chip surfaced on Geekbench 6.4 but researchers identify this sample as an engineering unit instead of an actual successor to the Core i9-14900K.
Core i9-15900K Benchmarked, But Is It Real?
Geekbench results indicate that the Core i9-15900K maintains the exact core-count and thread-count and cache levels as the 14900K with its 24 cores, 32 threads, 8MB L2 cache and 36MB L3 cache. The presented CPU originated from the manufacturing process of the 14900K before final product release so it functions more like a test unit than an advanced processor.
Intel tests its CPUs extensively in multiple stages before market release but engineering pre-production samples may start with alternative naming before receiving their final branding. Benchmarking databases frequently mistake prototype CPUs which worsens the identification problems.
The identification tag present on this chip acts as a prominent sign that it cannot be classified as true 15th-generation processor. The reported 15900K CPU matches Raptor Lake and Raptor Lake Refresh chips in using the GenuineIntel Family 6 Model 183 Stepping 1 CPU identifier. The actual Arrow Lake 15th-gen CPUs released by Intel will employ GenuineIntel Family 6 Model 198 Stepping 2 instead of the different Family 6 Model 183 Stepping 1.
Underwhelming Geekbench Performance
Even if this were a real Core i9-15900K, the performance results are underwhelming at best. The Geekbench 6.4 scores for this CPU are:
- Single-Core: 2279 points
- Multi-Core: 11,690 points
Single-core performance from the Core i9-14900K reaches 3000 points while its multi-core score reaches 20000 points. The leaked chip seems very weak because it may operate at reduced clock speeds. The Geekbench listing presents the 15900K processor with an 800 MHz base clock and 4.8 GHz boost clock speed although the 14900K utilizes P-Cores up to 5.8 GHz boost frequency.
The processor received testing through a JGINYUE B760I Snow Dream motherboard which functions as a B760 ITX motherboard produced by a Chinese manufacturer with limited market recognition. The persistent use of LGA 1700 socket will not reveal if the Core i9-15900K represents genuine future products or if it merely consists of Intel prototype devices with untrue naming.
Tested on a Chinese Motherboard
Anyone waiting for Intel to release a new CPU lineup should reduce their expectations because such plans do not exist at present. A so-called “15000” series from Intel will never exist as the company refuses to bring it to market. The genuine follow-up CPUs from Intel belong to the Core Ultra Series 2 which will launch during 2025.
The first impression of this Core i9-15900K Geekbench leak is not supported by the actual truth behind it. An engineering sample misidentified as 15900K might be the source of this information because the original 15th-gen Arrow Lake CPUs are yet to launch.
