Intel Core 3 N355: Why Eight Cores Don’t Make It a Regular Core

Eight cores, the Core brand, and a base power of 15W set expectations for the Intel Core 3 N355 to perform at the level of a typical mobile Core 3. In reality, it is the higher-end model of the budget N-series: lacking P-cores, featuring single-channel memory, and having notably weaker graphics compared to the Core 3 100U.

However, it cannot be placed on the same level as the four-core N100 and N150. The eight E-cores allow it to handle web browsing, office programs, messaging apps, and Windows background services more confidently. It is still a budget processor, but it is no longer the slowest representative in its class.

Eight E-Cores: A Bet on Multitasking

The Intel Core 3 N355 has eight cores and eight threads. All eight are power-efficient Gracemont cores. The processor lacks P-cores and Hyper-Threading. The maximum frequency reaches 3.9 GHz, and the cache size is 6 MB.

Eight simple cores are more beneficial when running multiple programs simultaneously than in a single demanding application. In multitasking mode, the N355 is noticeably more interesting than the four-core N-series processors.

However, eight cores do not place it alongside regular mobile Core 3s. A single Gracemont core significantly lags behind a P-core, so in tasks involving complex spreadsheets, photo processing, and compiling large projects, the N355 quickly hits a performance ceiling for individual cores.

N355 and N350: Almost the Same Processor with Different Limits

In terms of core specs, the Core 3 N355 is almost indistinguishable from the N350.

Parameter Core 3 N355 Core 3 N350
Cores and Threads 8 / 8 8 / 8
Max Frequency 3.9 GHz 3.9 GHz
Cache 6 MB 6 MB
Graphics 32 EU 32 EU
Graphics Frequency up to 1.35 GHz up to 1.35 GHz
Base Power 15 W 7 W

The main difference is the declared base power. With good cooling, the N355 can maintain high frequencies longer under sustained load.

The real difference is defined by the power settings and cooling of the specific device. The manufacturer might impose strict limits or install insufficient cooling systems. As a result, a poorly cooled laptop with an N355 might not outperform a well-tuned model with an N350.

It is not worth overpaying for the N355 index without comparing the laptops themselves.

N355 - A Slightly Boosted i3-N305

In configuration, the Core 3 N355 closely resembles the Core i3-N305. Both processors have eight cores, eight threads, 6 MB of cache, and a single-channel memory controller.

The clock frequency of the processor cores has increased from 3.8 to 3.9 GHz, and the integrated graphics frequency has risen from 1.25 to 1.35 GHz. The architecture has not changed: this is a point upgrade, not a new class of performance.

It makes little sense to switch from an i3-N305 laptop to a model with an N355. Compared to the N100 and N150, the increase is more noticeable: the number of cores increases from four to eight.

Memory and Graphics Reveal Budget Origins

The N355 supports DDR4-3200, DDR5-4800, and LPDDR5-4800 but is officially limited to 16 GB of RAM. The controller remains single-channel.

For browsing, office programs, and video calls, 16 GB is still sufficient. Versions with 8 GB are undesirable, especially with soldered memory that cannot be expanded. Part of the RAM is reserved for integrated graphics, while the remaining amount is consumed by Windows, browsers, and background applications.

The integrated graphics features 32 execution units and operates at a frequency of up to 1.35 GHz. It handles video and external monitors effortlessly but is only adequate for undemanding games.

Older and simpler games can run in 720p on low settings. Modern games are hindered by both the 32 graphics units and the single-channel memory. The integrated graphics use system RAM, so bandwidth directly impacts the frame rate.

Why N355 Is Not Equal to Core 3 100U

The N355 has eight cores, while the Core 3 100U has six. However, comparing these processors solely based on core count is misleading.

The Core 3 100U features two P-cores and four E-cores, clock speeds of up to 4.7 GHz, 10 MB of cache, a dual-channel memory controller, and graphics with 64 execution units.

The N355 only has E-cores, less cache, a single-channel memory controller, and half the number of graphics units. Consequently, the Core 3 100U is faster in demanding applications, single-threaded tasks, and games.

The true competitors of the N355 are the lower models of the N-series, not regular Core 3s.

Which Laptop with N355 Is Worth Buying

In a budget laptop, RAM, SSD, and cooling have a stronger impact on performance than the slight difference between N350 and N355.

The optimal configuration for the N355 is 16 GB of RAM and an SSD with at least 512 GB. Before purchasing, verify the ability to replace the SSD and expand the RAM: in compact laptops, the memory is often soldered.

It is not worth paying extra for an N355 in a laptop with a dull screen, 8 GB of soldered RAM, and a slow SSD. An eight-core processor does not compensate for savings on memory, display, and storage.

Who Is Suitable for Core 3 N355

The N355 is appropriate for affordable laptops and mini-PCs for education, office, and home use.

It is suitable for:

  • Browsing and office applications;
  • Video calls and watching movies;
  • Education and remote work;
  • Learning programming and small projects;
  • Older and undemanding games.

For video editing, modern gaming, virtual machines, and compiling large projects, it is better to choose a processor with P-cores.

Conclusion

The main value of the Intel Core 3 N355 lies in its eight cores within a budget platform. It is noticeably more appealing than the lower N-series processors in multitasking mode, but single-channel memory and the absence of P-cores prevent it from competing with regular mobile Core 3s.

The N355 makes sense in a laptop with 16 GB of RAM, a decent SSD, and a price significantly lower than models with Core 3 100U. If the device's price approaches laptops with the 100U, the advantages of the N355 disappear.

There are many manufacturers that design CPUs, which results in different instruction sets, such as the 8086 instruction set for the Intel camp and the RISC instruction set for the ARM camp. x86, ARM v8, and MIPS are all codes for instruction sets. Instruction sets can be extended; for example, x86 added 64-bit support to create x86-64. Manufacturers developing CPUs that are compatible with a certain instruction set need authorization from the instruction set patent holder. A typical example is Intel authorizing AMD, enabling the latter to develop CPUs compatible with the x86 instruction set.
