The Intel Core Ultra 5 135U is a mobile processor with 12 cores, launched in December 2023, at an MSRP of $332. It is part of the Ultra 5 lineup, using the Meteor Lake architecture with BGA 2049. Intel Hyper-Threading technology is available and effectly doubles the core-count of the P-Cores, to a total of 14 threads. Core Ultra 5 135U has 12 MB of L3 cache and operates at 1600 MHz by default, but can boost up to 4.4 GHz, depending on the workload. Intel is making the Core Ultra 5 135U on a 7 nm production node, the transistor count is unknown. The multiplier is locked on Core Ultra 5 135U, which limits its overclocking potential.
With a TDP of 15 W, the Core Ultra 5 135U consumes very little energy. Intel's processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 5600 MT/s, but with overclocking (and the right memory modules) you can go even higher. Actual memory technology support depends on the chosen motherboard, the processor itself supports multiple memory types, but most motherboards have only one kind of slot. For communication with other components in the computer, Core Ultra 5 135U uses a PCI-Express Gen 4 connection. This processor features the Arc Xe-LPG 64EU integrated graphics solution.
Hardware virtualization is available on the Core Ultra 5 135U, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512.
