Intel Core i3-10100Y vs Intel Core i3-N305

Intel Core i3-10100Y

The Intel Core i3-10100Y is a efficient dual-core SoC for tablets and passively cooled laptops based on the old Amber Lake generation from 2018. It was announced in Q1 2021 and is similar to the old Core i5-8200Y. The only difference is a slightly higher GPU clock (+50 MHz).

The CPU consists of two processor cores clocked at 1.3 - 3.9 GHz. Thanks to Hyper Threading, the processor can execute up to four threads simultaneously. The chips also includes the Intel HD Graphics 615 GPU, a dual-channel memory controller (DDR3L/LPDDR3) as well as VP9 and H.265 video de- and encoder.

Architecture

Intel basically used the familiar micro architecture from the Skylake / Kaby Lake generation, so the per-MHz performance is identical.

Performance

The average 10100Y in our database is just a little ahead of the AMD 3050e, as far as multi-thread benchmark scores are concerned, the latter being an entry-level, dual-core processor of the same energy efficiency based on the Zen architecture. This makes the Core i3 an OK option for basic day-to-day activities, as of mid 2022.

Your mileage may vary depending on how high the CPU power limits are.

Graphics

The integrated Intel UHD Graphics 615 iGPU has 24 Execution Units (EUs) not unlike the older HD Graphics 515 and runs at up to 1,000 MHz. The performance heavily depends on the TDP limit as well as the memory configuration; with fast LPDDR3-1866 RAM in dual-channel mode, the GPU should sometimes be able to compete with the HD Graphics 520, but can also be much slower in other scenarios. Modern games from 2016 will, if at all, only run smoothly in the lowest settings.

Contrary to Skylake, Kaby Lake and Amber Lake now also supports hardware decoding for H.265/HEVC Main10 with a 10-bit color depth as well as Google's VP9 codec.

Power consumption

This little Core i3 here has a default TDP, also known as the long-term power limit, of 5 W that laptop makers are free to change to anything between 3.5 W and 7 W with clock speeds and performance changing accordingly as a result. Either way, the values are low and thus good enough for passively cooled tablets, laptops, mini-PCs and handhelds.

The i3-10100Y is built with one of the old 14 nm Intel manufacturing processes for low, as of early 2023, energy efficiency.

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).
