Intel Core Ultra 5 Processor 135U

12C/14T · 4.4 GHz · 15 W

Intel Core Ultra 5 Processor 135U is a 15 W mobile processor from the Core Ultra Series 1 (Meteor Lake) family, launched in December 2023. It combines two Redwood Cove performance cores, eight Crestmont efficient cores and two low-power efficient cores for 12 cores and 14 threads, reaching 4.4 GHz on the performance cores, with 12 MB of Intel Smart Cache and a 15 W base / 57 W maximum turbo power envelope. The compute tile is built on the Intel 4 process and assembled with Intel Foveros 3D packaging. Integrated graphics are a four Xe-core Intel Graphics GPU running at up to 1.9 GHz, and the Intel AI Boost NPU is rated at 11 INT8 TOPS. Memory support covers LPDDR5X up to 7467 MT/s and DDR5 up to 5600 MT/s, two channels and 96 GB maximum, alongside 20 lanes of PCIe 4.0 in an FCBGA2049 package.

Notes
Intel validates Windows 11 only for Core Ultra Series 1; Windows 10 is not supported. Microsoft lists Core Ultra (Series 1) on the Windows 11 24H2 and 25H2 processor lists. Microsoft has not published a 26H2 processor list yet, so the 25H2 status is carried over here. Linux runs from kernel 6.7 onward; the NPU needs the intel_vpu driver.
