Intel’s mobile lineup features two distinct Arrow Lake series: the standard Arrow Lake-H (Core Ultra 200H) and the premium Arrow Lake-HX (Core Ultra 200HX), the latter designed for superior gaming and productivity performance.

Recently, the Core Ultra 9 275HX made headlines as one of the most powerful CPUs in the Arrow Lake lineup. Now, however, Geekbench has provided a sneak peek at the flagship processor: the Core Ultra 9 285HX.

It is important to note that the score was recorded in the Geekbench AI test, which differs from the traditional Geekbench CPU benchmark. Consequently, we have not yet fully assessed the 285HX’s capabilities in CPU performance, although the results yielded valuable insights.

In addition to its performance scores, the benchmark revealed that the Core Ultra 9 285HX is configured with 8 Performance cores and 16 Efficient cores. This configuration mirrors that of its desktop counterparts, including the Core Ultra 9 285K and Core Ultra 9 285. It’s crucial to note that the Core Ultra 9 285H from the Arrow Lake-H series consists of only 16 cores.

The base clock frequency for the Intel Core Ultra 9 285HX is documented as 2.8 GHz, though the maximum boost clock remains unconfirmed. This base clock aligns with pre-release leak patterns we noted earlier. Preliminary expectations suggest the CPU may reach boost speeds as high as 5.5 GHz for Performance cores and 2.1/4.6 GHz for Efficient cores. Moreover, speculation indicates the processor will include 36 MB of L3 cache and integrated graphics based on Intel’s Xe architecture, featuring 64 Execution Units (EUs) and a GPU core clocking at 2.0 GHz.

The Core Ultra 9 285HX is currently being tested within the MSI Raider 18 HX laptop, a flagship model tailored for gaming enthusiasts. While the exact graphics configuration in this iteration remains undisclosed, it is anticipated that it will support NVIDIA’s latest laptop GPUs, potentially such as the RTX 5090 or RTX 5080 series.
