Intel Celeron 5305U vs Intel Celeron N4500 vs Intel Core i5-10310U

Intel Celeron 5305U

The Intel Celeron 5305U is a low-power dual-core SoC for laptops, based on the Comet Lake architecture, which was introduced in 2020. Compared to Kaby Lake and Whiskey Lake, there are apparently no differences with Comet Lake apart from the two additional cores in the Top model Core i7-10710U. The processor is still manufactured using the mature 14nm process (14nm++ like Whiskey Lake). The processor cores clock at a fixed 2.3 GHz (no Turbo) and also only offer 2 threads (no HyperThreading). Compared to the more powerful Core i3, i5 and i7 variants, the Celeron does not offer SSE (2) support.

You can find more information about the Comet Lake architecture and the available processors on our Comet Lake topic page.

According to Intel, the integrated graphics card is called Intel UHD Graphics, but is an old Intel UHD Graphics 610. It is clocked in the Celeron 5205U at 300 - 900 MHz and is only sufficient for very demanding games. The CPU also offers an integrated DDR4-2666 / LPDDR4x 2933 / LPDDR3-2133 dual-channel memory controller as well as VP9 and H.265 video decoder and encoder.

Performance

The performance of the Celeron 5305U is in the lowest entry-level class of notebook processors in 2020. Due to the lack of Turbo and only 2 cores, the CPU cannot score points in either single-core or multi-core tasks. The processor is therefore only suitable for undemanding tasks such as surfing with a few tabs and office tasks.

The power consumption and performance can be set from 15 to 12.5 watts by the notebook manufacturer via cTDP-down. However, the processor then only runs at 800 MHz and significantly reduced performance. Even at 15 watts, however, the processor is suitable for thin and light notebooks.

Intel Celeron N4500

The Intel Celeron N4500 is a dual-core SoC of the Jasper Lake series that is primarily intended for inexpensive notebooks and was announced in early 2021. The two Tremont CPU cores clock between 1.1 and 2.8 GHz (single core Burst) and offer no HyperThreading. The N4500 uses 1.5 MB L2 and 4 MB L3 cache. The chip is manufactured on the first-gen 10 nm Intel process.

Architecture

The processor architecture is called Tremont and a complete redesign compared to the old Golmont Plus cores in the predecessor. According to Intel, the single thread performance of a core could is up two 30% better on average (10 - 80% in all tests of SPECint and SPECfp).

Features

In addition to the dual-core CPU block, the SoC integrates a 16 EU Intel UHD Graphics GPU clocked from 350 - 750 MHz and a dual-channel DDR4 / quad-channel LPDDR4(x) memory controller (up to 16 GB, up to 2933 MHz). The chip now also partly integrates Wi-Fi 6 (Gig+), 8 PCIe 3.0 lanes, 14 USB 2.0/ 3.2 ports and two SATA 6.0 ports. The package got bigger and measures 35 x 24 mm (compared to 25 x 24 mm for the N5030 e.g.). The SoC is directly soldered to the mainboard (BGA) and can't be easily replaced.

Performance

The average N4500 in our database shapes up to be a fairly slow processor, its multi-thread benchmark scores only just matching those of the Core i3-4010U. (The latter saw the light of day in 2013 as a lower mid-range, dual-core CPU designed for use in ultraportable laptops.) In other words, expect the Celeron to be painfully slow in all but the most basic activities.

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

Power consumption

Like most N-class Intel chips, the Celeron has a default TDP (also known as the long-term power limit) of 6 W. This is not much at all and thus good enough for passively cooled tablets, laptops, mini-PCs.

The Celeron N4500 is built with Intel's 2nd generation 10 nm process (not 10 nm SuperFin or Intel 7) for low, as of mid 2023, energy efficiency.

Intel Core i5-10310U

The Intel Core i5-10310U is a power efficient quad-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in August 2019. Compared to the similar Whiskey Lake processors (e.g. Core i5-8665U), the only difference is support for higher memory speeds (DDR4-2666 vs 2400) and two additional cores in the top model (not in this i5). The processor cores are clocked between 1.7 and 4.4 GHz (unverified). Thanks to HyperThreading 8 threads can be used. Compared to the faster i5-10510U, the level 3 cache was reduced from 8 to 6 MB. More information on Comet Lake and all the models and articles on it can be found here. The CPU supports the professional management features under the vPro umbrella.

The integrated graphics adapter however is still the same as in the previous generations. It should be still called Intel HD Graphics 620 and clock from 300 - 1100 MHz in the i5. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel DDR4-2666 / LPDDR4x 2933 / LPDDR3-2133 memory controller.

Performance

The average 10310U in our database is not really any different than other quad-core laptop CPUs running at similar clock speeds, such as the Ryzen 5 3450U or the Core i5-1035G4.

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

Power consumption

This Core i5 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are free to change to anything between 10 W and 25 W with clock speeds and performance changing correspondingly. Perhaps more importantly, short-term power consumption can be as high as 80 W or even 90 W as far as 10th gen Comet Lake U chips are concerned, making passively cooled designs unlikely.

This Intel processor is manufactured on a fairly old, as of late 2022, 14 nm Intel process for subpar energy efficiency.
