A recent benchmark test using Cinebench R23 showed that the upcoming Intel Core Ultra 9 275HX is slightly behind its predecessor in single-core performance but excels in multicore performance. The high-end Arrow Lake-HX chip has now been tested on Passmark, and the results are quite impressive. In single-core performance, the Core Ultra 9 275HX outperforms the i9 14900HX by approximately 10%, showing a significant generational improvement. Overall, the Core Ultra 9 275HX performs 33% better than its predecessor. It is important to note that these improvements may be lower in real-world scenarios, as there are over 1800 entries for systems powered by the i9 14900HX in the Passmark database, compared to only one entry for the 275HX.
The Core Ultra 9 275HX was first introduced at CES 2025 and features 8 Lion Cove P-cores and 16 Skymont E-cores. Intel has moved away from Hyper-Threading with its Arrow Lake lineup, but the Passmark results suggest that the Arrow Lake-HX chip performs well without it. The performance of laptops using this system will heavily depend on their thermal capabilities, meaning that some systems may not fully utilize the potential of the 275HX. As with all pre-release benchmark leaks, it is important to take this information with caution. The Ryzen 7945HX3D lags behind, but only by around 7% in overall performance. With the upcoming Ryzen 9 9955HX3D on the horizon, Intel's dominance in high-end laptops may be short-lived.
