Intel’s 13th Generation Core Processors for Laptops


Following the release of the desktop version, Intel’s 13th-generation Core processors for laptops at CES 2023 have been released. Here is an overview of what you need to know about these new mobile processors.

Intel has already released its 13th generation of SoCs for desktop computers and high-end gaming PCs. This increased competition with AMD’s Ryzen has resulted in improvements from both brands. However, the desktop market is a specialized world, and to reach a wider audience, laptops are the way to go. At CES 2023, Intel unveiled its full line-up of CPUs for the mobile market, including options for creators, gamers, and a variety of different devices. Here is an overview of the processors that will be available in 2023.

The Intel Core i9-13900HX, the flagship

If you’re looking for the best that Intel has to offer for laptops in 2023, look no further than the i9-13980HX. This processor has a total of 24 cores – 8 performance cores and 16 efficient cores – for a total of 32 threads, with a 36 MB L3 cache and a maximum turbo frequency of 5.6 GHz. The SoC has a base power consumption of 55W, with a maximum of 157W.

The 13th generation HX platform features an improved thread director, and supports DDR5 RAM up to 5600 MHz and DDR4 up to 3200 MHz. It include XMP 3 as well. In terms of connectivity, there is support for PCIe Gen 5 x16 (or 2×8 for the manufacturer’s choice) and the ability to use up to 2 Thunderbolt 4 controllers at 40 Gbps. The platform will also allow for the use of Intel Killer Wi-Fi 6E cards and Bluetooth LE Audio.

In terms of performance, the manufacturer claims an 11% increase in single-thread performance and a 49% increase in multitasking performance compared to the base Intel Core i9-12900HK, not its equivalent HX version. The comparison is also made with the Ryzen R9 6900HX, which appears to be significantly behind, although it is not an equivalent generation (the 7000 for mobile is expected) and is not integrated into an equivalent thermal management configuration (MSI Titan GT77 versus Alienware M17, it’s not quite the same, Intel). In terms of gaming, Intel expects an overall 12% performance increase compared to an equivalent configuration i9-12900HX.

The 13th generation Intel P and U, for mobility

These are the two references from Intel that you will see most frequently throughout the year. Mid-range PCs and ultrabooks typically use these processors.

In the P category, the main representative is the i7-1370P with 14 cores – 6 performance and 8 efficient – and 20 threads, with 24MB of L3 cache, able to turbo up to 5.2 GHz with a TDP of 28W. In the U category, we find the i7-1365U with 10 cores – 2 performance and 8 efficient – and 12 threads, with 12MB of L3 cache, able to turbo up to 5.2 GHz with a TDP of 15W.

These also benefit from the major improvements to the platform, including the interesting integration of Intel Movidius. This is a module dedicated to accelerating artificial intelligence operations, which can have a significant impact, particularly on the quality of video recordings and streams or the dynamic management of CPU/GPU load. However, Unfortunately, Intel Movidius is not a standard feature in all chips and must be added as a discrete option.

The Intel N and i3 N are accessible and durable computers

Previously, these processors were known as Pentium and Celeron. These two names, which are now only recognized by the elderly (we are getting old), have been discarded and the range has been simplified to simply be called “N”. This year we have two variations: the classic N range, and the i3 N.

The Core i3-N-305, the flagship of the category, will offer 8 cores for 8 threads and 6MB of cache, with a turbo of 3.8 GHz for a TDP of 15W. However, most manufacturers will probably turn to the Intel N200, a 4-core and 4-thread processor with 6MB of cache that can reach up to 3.7 GHz. Here, we are on a TDP of 6W. The Intel N200 represents a 28% performance gain on CrossMark compared to the Pentium Silver N600, while the Intel Core i3-N305 is 42% more powerful than the N200.

Of course, the machines that will incorporate these configurations will not be the most powerful on the market, that is obvious. These processors will likely be integrated into B2B solutions, including video advertising panels. That being said, these SoCs are very important in ultra-affordable product categories, such as Chromebooks and small Windows tablets. And for them, these Intel Ns are an excellent evolution: they are now engraved using the Intel 7 process, support Wi-Fi 6E and Bluetooth 5.2, and offer AV1 decoding and eDP 1.4b for connecting high-resolution screens. This will greatly modernize the most financially accessible products while also providing them with a certain longevity.

The Intel Evo certification is evolving for the better

The Intel Evo certification continues on this 13th generation but is evolving for the better. To recall, it exists to highlight laptops that meet numerous quality criteria established by Intel itself. For its 13th generation of processors, Intel emphasizes the importance of device autonomy, responsiveness, and fluidity, regardless of whether the device is plugged in. These processors also support multi-device use with the Intel Unison platform.

But the the biggest novelty of the certification this year is that it finally accepts machines that incorporate GPUs from other suppliers. Therefore, PCs with an Nvidia or AMD graphics cards can also be EVO certified; this will not prevent them from having to meet certain quality requirements for graphics tasks of course.

Release date and information on the Raspberry Pi 5

Release date and information on the Raspberry Pi 5

After many releases of new products from the Raspberry Pi Foundation, it has been less active in recent months. However, everything seems to show that the foundation is already working on the next Raspberry Pi. That includes the Raspberry Pi 5. Check out our article about the Raspberry Pi and its uses if you don’t know what it is.

The Raspberry Pi 5: In preparation but no release date yet

Although the Raspberry Pi Foundation has not yet announced the release date of the Raspberry Pi 5, it is indeed part of its plans.

Eben Upton, CEO of the Raspberry Pi Foundation has already announced a new Raspberry Pi with a more powerful and faster SoC. Also, the next Raspberry Pi should have a better USB input/output chip, more RAM memory and improved network connectivity (Ethernet/Wifi).

SoC: System on a Chip (Chip present on the processor)

Like each new version of the Raspberry Pi, this one will be even closer to a classic computer by being even more powerful than the Raspberry Pi 4. On the other hand, the foundation should keep the system set up with the Raspberry Pi 4, that is to say several versions of the Raspberry Pi 5 available, having a different RAM size and a different price as well.

Regarding the release date of the Raspberry Pi 5, we have no information yet but it should not see the light of day before mid 2022, or even early 2023 if an improved version of the Raspberry Pi 4 were to be released in the meantime.

Before the Pi 5 Released: An Improved Version of the Raspberry Pi 4

The release of the Raspberry Pi 4 is starting to date and many users are asking for a revision of the latest model from the Raspberry Pi foundation.

Based on the history of the foundation, we should see an update to the Raspberry Pi 4 (the Raspberry Pi 4A).

According to rumors concerning this new Raspberry Pi 4, improvements should be made to the SoC and to the USB ports which could give way to PCIe connectivity. The latter is already in place on the Compute Module 4.

What does the community want for the Raspberry Pi 5?

The best way to find out what the Raspberry Pi 5 will include is to ask what the community wants to see for the next Raspberry Pi 5.

1. Fix the bugs present in the Pi 4

The Pi 5 is expected to alleviate issues that the current versions have, such as:

  • USB-C power issues

There are many USB-C power adapters with fast charging technologies such as QuickCharge, DashCharge or SuperCharge. A hardware design flaw in the Raspberry Pi 4/4B is known to cause some adapters to misinterpret the device type. As a result, these adapters will provide more than 5V to power our Pi. This can sometimes burn out the board’s power supply or worse, the entire CPU .

So hopefully the Pi 5 doesn’t have the same design flaws.

  • The USB hub and the Ethernet chip

The 4-ports USB hub & the Gigabit Ethernet controller of the Raspberry Pi 4 have sometimes become hot. Even when no device is plugged in.

This problem has only been encountered by some users and no specific reason has been found.

Result, an increase in standby temperature means a decrease in the life time of the components.

  • The low voltage warning

It happened that a window appeared in the office asking to check the power supply. This problem may appear even when the power supply is new and after checking it has no problem.

In the Raspberry Pi 5, this should be fixed. It can only be triggered if the Pi is really struggling to draw enough current from the power supply.

2. Take over some features of the Raspberry Pi Pico in the Raspberry Pi 5?

Not too long ago, Raspberry Pi introduced its own microcontroller, the Raspberry Pi Pico. With a host of features such as the programmable IO state machine subsystem.

We know that being a microprocessor-based system, Raspberry Pis are not designed to perform critical tasks. For example, they can’t generate PWM signal, DAC and ADC functions, let alone handling interrupts.

Therefore, how about an integration of some of the Pico functions into the Raspberry Pi 5 such as:

  • Analog inputs (ADC).
  • Hardware PWM outputs.
  • IO programmable state machine system.
  • Additional hardware UART interfaces.
  • On-chip accelerated floating point and integer libraries.
  • Hardware Interrupts.
  • RTC & low power modes supported by the microcontroller part of the system.

Another subject is the design and size of the Raspberry Pi 5. This subject is debated because not all users agree: some want change while others strongly oppose it.

And you, what do you expect from the Raspberry Pi 5? Let us know in the comments below.

What is arduino ?

what is arduino

Arduino® is a hardware and software package that allows you to learn electronics (while having fun) while becoming familiar with computer programming. Unlike other boards, Raspberry Pi for example, Arduino is open source, so you can download the original schematic and use it to build your own map and sell it without paying royalties.

The Hardware

They are programmable electronic cards (therefore equipped with a processor and memory) on which we can connect temperature, humidity, vibration or light sensors, a camera, buttons, adjustment potentiometers, contacts electric… There are also connectors for connecting LEDs, motors, relays, displays, a screen…

An Arduino board is a brain that makes electronic systems intelligent and animates mechanical devices.

The image below shows an the Uno board which is widely used for beginners.

An Arduino Uno board with its connectors.

In writing related to Arduino you will often see the words “microprocessor”, “micro-controller”, “MCU”, “AVR”, “ATMega168”, “ARMCortex-M3”…

In a very simplified way: all these terms designate a processor. The processor is the calculation unit (CPU) contained inside the integrated circuit designated by one of the terms previously mentioned (example: MCU, ATmega168, etc.)

The Software IDE

The creators of Arduino have developed software to make programming arduino boards visual, simple and complete at the same time.
This is called an IDE, which stands for Integrated Development Environment.

The Arduino IDE is the software used to program Arduino boards.

The IDE displays a graphics window that contains a text editor and all the tools needed for programming activity.
You can therefore enter your program, save it, compile it, check it, transfer it to an arduino board…
At the time of writing this page, the most recent version of the Arduino IDE is 1.8.10. The look is pretty much the same on every platform (Windows, Mac, and Linux). The following image shows the initial screen that appears when launching the IDE.

Types of Arduino Boards

Over the years, the designers at have come up with a number of board designs. The first Arduino board, the Diecimila, was released in 2007. And since then, the Arduino family has evolved to take advantage of the different types of Atmel microprocessors.

The Due, released in 2012, is the first Arduino to use a 32-bit ARMCortex-M3 processor. It stands out from the rest of the family in terms of processing power and board pinout configuration.
Other boards, like the LilyPad and the Nano, don’t have the same pinout as well and are aimed at a different range of rather “mobile” applications.
In the case of the LilyPad it is for easy integration into clothing and fabrics.
The Esplora integrates sensors and actuators and the compact size of the Mini, Micro and Nano predestines them for miniature, light and discreet applications.

When several types of microcontrollers are indicated, it means that an early version was produced with the first type and later with the other (generally more powerful).
For example, an older version of the Duemilanove will have an ATmega168, while newer models will have the ATmega328. Functionally, the ATmega168 and ATmega328 are identical, but the ATmega328 has more internal memory.

The latest additions to the Arduino family, Leonardo, Esplora, Micro and Yún, all use the ATmega32U4 microcontroller. If the latter is similar to an ATmega328, it also integrates a USB serial interface component, which eliminates an integrated circuit (easier routing) like the one present on the Uno and Duemilanove boards (ATmega16U2, FT232RL).

Arduino naming convention

Although the design of the Arduino circuit and its software is open source, the Arduino team has reserved the use of the term “Arduino” for its own designs.
The Arduino logo is a registered trademark.

You will sometimes find builds that look like official Arduino boards, but are not produced by the Arduino team. Some manufacturers use “-duino” or “-ino” in the product name, such as Freeduino, Funduino, Diavolino, Youduino, etc. Some, like boards made by SainSmart, use only the model name (Uno and Mega2560 for example).

Due to a dispute between the company created by the original founders (Arduino LLC) and a different company created by one of the original founders (Arduino SRL), Arduino LLC uses the Arduino trademark in the United States and Genuino elsewhere.

Some “manufacturers” claim to be selling an Arduino board, but are actually just a copy using the trademark without permission.
Massimo Banzi has dedicated a section of his blog to these blatant unauthorized copies.

The main point to remember here is that you can copy the schematics, the bootloader code, the Arduino IDE code and use them to create your own version (open source principle) .
Just don’t call it ‘Arduino’.

What can you do with an Arduino?

In addition to the ease of programming made possible by the Arduino IDE, the other great feature of an Arduino is the capability of the microcontroller on which it is based.
With a few extra shields readily available, a wide selection of inexpensive sensor modules and actuators, there really isn’t much you can’t do with an Arduino.
The condition is to keep in mind a few basic constraints: memory, clock frequency, peripheral output currents and voltage levels.

Here are some possible applications for an Arduino:

Measurement and detection

  • Automated Weather Station.
  • Lightning detector.
  • Tracking of the sun for orientation of the solar panels.
  • Radiation monitor.
  • Automatic wildlife detector.
  • Home or business security system.


  • Little robots.
  • Rocket or airplane model.
  • Multi-rotor drones.
  • Simple CNC for small machine tools.


  • Automated greenhouse.
  • Automated aquarium.
  • Laboratory sample shuttle robot.
  • Precision thermal chamber.
  • Automated electronic test system.

What Is Raspberry Pi?

The evolution of computers has led to the creation of the Raspberry Pi, a small, low-cost computer that is accessible to people of all backgrounds and skill levels. While computers have become commonplace in many parts of the world, they are still not widely available in developing countries. The Raspberry Pi was developed by the Raspberry Pi Foundation in the UK as a solution to this problem, providing an affordable and easy-to-use computer that can be used for a variety of purposes, including learning programming languages and managing networks. The Raspberry Pi is a single-board computer about the size of a credit card and can be connected to a variety of hardware devices such as a keyboard, mouse, and monitor. It has gained increased popularity in recent years due to its versatility and affordability.

How does Raspberry Pi work?

The Raspberry Pi is a compact and programmable device that contains the essential features of a motherboard, but does not come with peripherals or internal storage. To use it, you will need to insert an SD card with the operating system installed into the designated slot in order to boot the computer. The Raspberry Pi is compatible with Linux OS, which helps to reduce the amount of memory required and allows for a wide range of potential applications. After setting up the operating system, you can connect the Raspberry Pi to output devices like monitors or TVs via HDMI, and input devices like mice and keyboards. The specific uses and applications for the Raspberry Pi depend on the user and can vary greatly.
