The Intel Core Ultra 9 285T is a desktop processor built on a 3 nm semiconductor process and designed for the LGA 1851 socket, with compatibility limited to Z890 chipsets. It carries a 35W Thermal Design Power, a maximum operating temperature of 105 °C, and includes integrated graphics. The chip supports 64-bit computing and connects to expansion hardware via PCIe 5.
The processor uses big.LITTLE technology to arrange its cores into two groups — 8 cores running at 1.4 GHz and 16 cores at 1.2 GHz — for a total of 24 threads. With Turbo Boost version 2, it can reach a turbo clock speed of 5.4 GHz, while the base clock multiplier sits at 14. It includes 40 MB of L2 cache and does not feature an unlocked multiplier, meaning clock speeds cannot be freely adjusted beyond factory settings.
In PassMark testing, this processor achieves a multi-core score of 36,940, reflecting its overall throughput across all available cores and threads. Its single-core PassMark result stands at 4,775, indicating the per-core processing capability measured under single-threaded workloads.
The integrated graphics unit has a base clock of 300 MHz and a turbo frequency of 2000 MHz, with support for up to 4 simultaneous displays. It is compatible with DirectX 12, OpenGL 4.5, and OpenCL 3, covering a broad range of graphics and compute workloads handled directly by the integrated solution.
This processor supports DDR5 memory at speeds up to 6400 MHz across a dual-channel configuration, allowing for a maximum installed capacity of 192 GB. It also includes support for ECC memory, which enables error detection and correction during operation.
The processor supports a wide range of instruction sets including MMX, AVX, AVX2, FMA3, AES, F16C, SSE 4.1, and SSE 4.2, covering vector operations, encryption acceleration, and extended floating-point handling. It also includes the NX bit, a hardware-level security feature that helps prevent certain classes of malicious code from executing in memory regions marked as non-executable.
