Intel Celeron 5305U vs Intel Celeron N4505

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 N4505

The Intel Celeron N4505 is a dual-core SoC of the Jasper Lake series that is primarily intended for inexpensive and small desktops and was announced in early 2021. The two Tremont CPU cores clock between 2 and 2.9 GHz (single core Burst) and offer no HyperThreading (SMT). The N4505 uses 1.5 MB L2 and 4 MB L3 cache. The chip is built with Intel's first-gen 10 nm process, just like Ice Lake family processors.

CPU 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 be improved by 30% 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 450 - 750 MHz and a LPDDR4(x) dual channel memory controller (up to 16 GB and 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 N4505 in our database is just as fast as AMD's dual-core Athlon Silver 3050e and Intel's previous-gen Celeron N4100, as far as multi-thread benchmark scores are concerned. In other words, the Celeron is good for basic day-to-day activities but not much more than that, as of mid 2022.

Power consumption

This Celeron series SoC has a default TDP, also known as the long-term Power Limit, of 10 W, which is low enough to allow for passively cooled designs.

The N4505 is manufactured on the first-gen or the second-gen (no exact data available) 10 nm Intel process making for average, as of late 2022, energy efficiency.
