Intel's 2024 flagship based on the Arrow Lake architecture, focusing on significantly improved power efficiency.

Built with 24 cores and 24 threads, the Core Ultra 9 285K is designed for high-end desktop CPU workloads on the Arrow Lake-S architecture.
The processor runs at a 3.7 GHz base frequency and can boost up to 5.7 GHz, with 36 MB of Intel Smart Cache.
LGA 1851 compatibility includes DDR5 6400 MT/s memory support, PCI Express 5.0 and 4.0, integrated Intel Graphics, and an unlocked multiplier for overclocking.
The Intel Core Ultra 9 285K is a 2024 Arrow Lake-S desktop CPU for the LGA 1851 platform, featuring 24 cores and 24 threads, up to 5.7 GHz max turbo frequency, DDR5 6400 MT/s support, integrated Intel Graphics, and PCI Express 5.0/4.0 connectivity; no CPU cooler is included.
The reviewer describes the CPU as currently undercooked with inconsistent gaming results and stability issues. They do not recommend purchasing it until these issues are addressed.
The publication concludes the CPU lacks a strong place in the market, noting that it is not broadly justifiable due to its high cost and inferior gaming/efficiency performance compared to AMD's alternatives. They do acknowledge improved power efficiency and memory overclocking potential.
The reviewer notes that while the reduced power consumption is a positive step, the second-rate gaming performance is a significant backward step compared to previous generations and competitors, making it difficult to recommend at its current price.
The reviewer characterizes the processor as a mixed bag, highlighting strong multi-threading performance, integrated graphics, and power efficiency, but advising gamers to avoid the chip for now.
