Core i3-1305U

The Core i3-1305U is a 5-core / 6-thread processor based on the Raptor Lake-U (2023) architecture, manufactured on a Intel 7 nm process node. It reaches a maximum boost clock of 4.5 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 10 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 8,634, placing it in the Budget performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,960, while multi-core reaches 1,900. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 4,388.

The Core i3-1305U fits into the FCBGA1744 socket and supports PCIe 5.0 with 20 total PCIe lanes for expansion cards and storage. It supports DDR5-5200, DDR4-3200, LPDDR4x-4267 memory at speeds up to DDR5-5200 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 96 GB across 2 channels (dual-channel doubles bandwidth). Integrated graphics: Intel UHD Graphics — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

The Core i3-1305U is primarily designed for Budget Laptop. Virtualization: VT-x, VT-d — enables running virtual machines efficiently (important for development and server workloads).

The Core i3-1305U 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: Laptop Cooling.

Performance ranking position: #1398 out of all indexed processors.
