Intel Core i5-1245U

The Intel Core i5-1245U is a mobile processor with 10 cores, launched in February 2022. It is part of the Core i5 lineup, using the Alder Lake-U architecture with BGA 1744. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 12 threads. Core i5-1245U has 12MB 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 i5-1245U on a 10 nm production node, the transistor count is unknown. The multiplier is locked on Core i5-1245U, which limits its overclocking potential. With a TDP of 15 W, the Core i5-1245U consumes very little energy. Intel's processor supports DDR4 and DDR5 memory with adual-channel interface. For communication with other components in the computer, Core i5-1245U uses a PCI-Express Gen 4 connection. This processor features the Iris Xe 80EU integrated graphics solution. Hardware virtualization is available on the Core i5-1245U, 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.
