Core i5-1245U

The Core i5-1245U is a 10-core / 12-thread processor based on the Alder Lake-U (2022) architecture, manufactured on a Intel 7 nm process node. It reaches a maximum boost clock of 4.4 GHz from a base frequency of 1.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 12 MB (total) of L3 cache, plus 1.25 MB (per core) of L2 cache and 80K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 12,964, placing it in the Budget performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,150.

The Core i5-1245U fits into the FCBGA1744 socket and supports PCIe 5.0 with 20 total PCIe lanes for expansion cards and storage. It supports DDR4, DDR5 memory at speeds up to LPDDR5-5200 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 64 GB across 2 channels (dual-channel doubles bandwidth). Integrated graphics: Iris Xe Graphics 80EU — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

The Core i5-1245U is primarily designed for Business Laptop. Virtualization: VT-x, VT-d, EPT — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Ryzen 5 PRO 6650U.

The Core i5-1245U has a rated TDP (Thermal Design Power) of 15 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: None.

Performance ranking position: #1145 out of all indexed processors.
