Intel Core i3-N305

The Intel Core i3-N305 is an entry-level mobile CPU for thin and light laptops from the Alder Lake-N series. It was announced in early 2023 and offers no performance cores and 8 efficient cores (E-cores, Gracemont architecture). The chip does not support HyperThreading and clocks with up to 3.8 GHz. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 6 MB L3-cache.

Performance

We have not tested a single system built around the N305, as of September 2023. Expect the chip to be 50% to 100% faster than the N95 (4 cores, 4 threads, up to 3.4 GHz).

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solutuion of your system is.

Features

The Alder Lake-N chips only support single channel memory with up to DDR5-4800, DDR4-3200 or LPDDR5-4800. The chip also supports Quick Sync and AV1 decoding (most likely same engine as in Alder Lake). Furthermore, Wi-Fi 6E and Bluetooth 5.2 are partly integrated (but no Thunderbolt). External chips can be connected via PCIe Gen3 x9 (via the PCH).

The integrated graphics adapter is based on the Xe-architecture and offersall 32 EUs (Execution Units) operating at up to 1.25 GHz. In addition to the single channel memory, the gaming performance is very limited of the iGPU.

Power consumption

The i3 has a base power consumption of 15 W and can be configured down to 9 W. The CPU is built with a further improved 10nm SuperFin process at Intel (called Intel 7).
