Intel is set to unveil its new line of desktop processors known as Arrow Lake-S. Several references are expected including a showcase, the Core Ultra 9 285K.
Arrow Lake-S processors use a hybrid architecture with “Performance” cores, aka “Lion Cove” P-Cores, and efficient cores, “Skymont” E-Cores. This choice from Intel is supposed to optimize intensive tasks and those that require fewer resources. The Core Ultra 9 285K is equipped with 8 P-Cores and 16 E-Cores, identical to its predecessor except for a difference in size. Hyper-Threading technology is no longer supported. In short, there are no more logical cores. If the Core i9-14900K is a 24C/32T chip, the Core Ultra 9 285K is a 24C/24T solution
Core Ultra 9 285K, performance.
The latest leaks concern the Core Ultra 9 285K unveils its performance score under the PassMark benchmark. It scores 5268 points, which is 8% higher than that of the Core i9-14900KS and 11% higher than that of the Core i9-14900K. However, due to the lack of hyper-threading, its multithreaded performance is strongly affected, with a decline of 22% compared to its elders. It is positioned ahead of the Ryzen 9 9950X (+11%), however, AMD plans to launch more powerful X3D variants.
For the moment and unlike other models in the series such as the Core Ultra 7 265K and the Core Ultra 5 245K, the 285K will not offer a variant without iGPU (KF).
It appears from these latest leaks that this Core Ultra 9 285K seems to provide a significant improvement in raw performance compared to its predecessors and the competition embodied by AMD. However, the lack of Hyper-Threading could be a limiting factor in some heavily multithreaded applications.
Intel will also have to prepare for the arrival of the Ryzen 9000X3D.
