Intel Celeron N4505 vs Intel Core i7-3635QM vs Intel Celeron N5095

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.

Intel Core i7-3635QM

The Intel Core i7-3635QM is a fast quad-core processor for laptops based on the Ivy Bridge architecture. Due to Hyperthreading, the four cores can handle up to eight threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.4 GHz but can dynamically increase clock rates with Turbo Boost up to 3.2 GHz (for 4 active cores), 3.3 GHz (for 2 active cores) and 3.4 GHz (for 1 active core). In contrast to the 3630QM, the 3635QM has a different package (BGA) and a slightly higher GPU clock.

Ivy Bridge is an enhanced die shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Other new features are integrated PCI Express 3.0 and  DDR3(L)-1600 support.

The performance of the Core i7-3635QM is slightly above a similarly clocked Sandy Bridge processor due to slight architectural improvements. As a result, overall performance is similar to the fastest Sandy Bridge model, the Core i7-2960XM.

The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1200 MHz with Turbo Boost, making it one of the faster variants.

As with most quad-core Ivy Bridge models, the Core i7-3635QM is specified at a TDP of 45 Watts including graphics card and memory controller. Therefore, the CPU is well-suited for laptops 15-inches or greater.

Intel Celeron N5095

The Celeron N5095 is an inexpensive quad-core SoC of the Jasper Lake product family designed for use in affordable SFF desktops and laptops. It features four Tremont CPU cores running at 2 GHz that Boost to up to 2.9 GHz with no thread-doubling Hyper-Threading technology in sight. A pretty basic iGPU is present as well.

The only difference between the N5095 and the N5095A is that the latter comes with support for more proprietary Intel technologies such as the Smart Sound DSP, Wake on Voice and HD Audio.

Architecture and Features

Tremont brings many improvements over Goldmont Plus, the architecture that we know from the N5030 and myriads of other N-class CPUs. An up to 30% boost in single-thread performance is to be expected thanks to smarter prefetchers, branch prediction improvements and other refinements, according to Intel. These new chips are physically larger than their immediate predecessors as a result. Either way, this is still a "small" core rather than a "big" one according to ChipsAndCheese.

The Celeron has 1.5 MB of L2 and 4 MB of L3 cache and is compatible with DDR4-2933 and LPDDR4x-2933 memory or slower. Support for Intel CNVi Wi-Fi 6 modules is baked into the chip, as are 8 PCIe 3.0 lanes for NVMe SSD speeds up to 3.9 GB/s. USB 4 or Thunderbolt aren't supported however.

Please also note that the Celeron gets soldered to the motherboard (BGA1338 socket interface) for good and is thus not user-replaceable.

Performance

The average N5095 in our database is about as fast as the Core i3-10110U, Core i3-1005G1, Celeron N5105 and also the Ryzen 3 3200U in multi-threaded workloads. Which is just enough for the most basic of tasks in late 2024.

Performance will get a significant hit if the power target is set to 10 W or 6 W instead of the Intel-recommended 15 W value.

Graphics

The DirectX 12.1-capable 16 EU UHD Graphics runs at up to 750 MHz and is in many respects similar to what Ice Lake CPUs come equipped with. This graphics adapter is capable of driving up to 3 SUHD displays simultaneously; HEVC, AVC, VP9, MPEG-2 and other popular video codecs can all be hardware-decoded. AV1 and VVC can't.

As far as gaming is concerned, it is reasonable to expect playable framerates in really old games (like Dota 2 Reborn) provided one sticks to lower resolutions such as HD 720p.

Power consumption

While most N-class chips have a 6 W long-term power target, the Celeron N5095 has a 15 W TDP to mimic much faster U-class Core processors. This isn't a great CPU for passively cooled designs.

The N5095 is built with the same 10 nm Intel process as Ice Lake-U processors for pretty unimpressive power efficiency, as of late 2024.
