Intel Celeron 6305 vs Intel Celeron N5100

Intel Celeron 6305

The Intel Celeron 6305 (or 6305U) is a power efficient dual-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced in the third quarter of 2020. It integrates only two Willow Cove processor cores (2 threads - no Hyper-Threading/SMT). The clock speed is set at 1.8 GHz as the chip does not support Turbo Boost.

Performance

The average 6305 in our database is in the same league as the Celeron N4505, as far as multi-thread benchmark scores are concerned. This is a very poor result, as of late 2022.

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

Another novelty is the integrated Xe graphics фвфзеук based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older UHD Graphics G1 (Ice Lake). In the 6305U Intel calls it just UHD Graphics and it offers 48 EUs.

Other improvements from Ice Lake should be also integrated in Tiger Lake like the AI hardware acceleration and the partial integration of Thunderbolt and Wifi 6 in the chip.

The chip is produced on the improved 10nm+ process (called 10 nm SuperFin) at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).

Intel Celeron N5100

The Intel Celeron N5100 is a quad-core SoC of the Jasper Lake series that is primarily intended for inexpensive notebooks and was announced in early 2021. The four Tremont CPU cores clock between 1.1 and 2.8 GHz (single core Burst) and offer no HyperThreading (SMT). The N5100 uses 1.5 MB L2 and 4 MB L3 cache. The chip is manufactured in 10nm at Intel (most likely in the same process as Ice Lake).

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 quad-core CPU block, the SoC integrates a 24 EU Intel UHD Graphics GPU clocked from 350 - 800 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

While we have not tested a single system powered by the N5100 as of August 2023, it's safe to expect the chip to be 10% to 20% slower than the N6000, as far as multi-thread performance is concerned. In other words, this is a fairly slow processor that is unlikely to make anybody happy.

Power Consumption

Like most other N-class Intel processors, this Celeron has a 6 W default TDP (also known as the long-term power limit). This is rather low; a small metal plate is all it takes to dissipate heat generated by such a CPU.

The Celeron N5100 is manufactured on Intel's first-generation or second-generation [no exact data available] 10 nm process for average, as of early 2023, energy efficiency.
