Core Ultra 9 285T

The Core Ultra 9 285T is a 24-core / 24-thread processor based on the Arrow Lake-S (2024−2025) architecture, manufactured on a 3 nm process node. It reaches a maximum boost clock of 5.4 GHz from a base frequency of 1.4 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 36 MB (total) of L3 cache, plus 3 MB (per core) of L2 cache and 192 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 36,916, placing it in the High-End performance tier as a Current Gen generation product.

The Core Ultra 9 285T fits into the LGA1851 socket and supports PCIe 5.0 with 20 total PCIe lanes for expansion cards and storage. It supports DDR5-6400 memory at speeds up to 6400 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 256 across 2 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers. Integrated graphics: Intel Arc Xe-LPG Graphics — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

Virtualization: VT-x, VT-d — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Ryzen 9 7900.

The Core Ultra 9 285T has a rated TDP (Thermal Design Power) of 35 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately. Recommended cooling: Efficient Air Cooler.

At an average price of $549, the Core Ultra 9 285T delivers 67 PassMark points per dollar. Performance ranking position: #321 out of all indexed processors.
