3. Processor and Power

* iPhone X - 10nm A11 chip, 6-core, 3GB RAM
* Galaxy Note 8 - Qualcomm Snapdragon 835 octa-core chipset (4x 2.35GHz and 4x 1.9GHz Kryo CPUs), Adreno 540 GPU, 6GB RAM
* Galaxy S8/Plus - Qualcomm Snapdragon 835 octa-core chipset (4x 2.35GHz and 4x 1.9GHz Kryo CPUs), Adreno 540 GPU, 4GB RAM

In iPhone vs Galaxy Note 8 vs Galaxy S8 comparison, iPhone X has the smallest RAM: 3GB vs 6GB vs 4GB. But still, iPhone X may be the most powerful smartphone. It sports an Apple-designed A11 chip which has six cores, two high-performance "Mistral“ CPU cores and four low-power cores, called ”Monsoon“. All the six cores in iPhone X's A11 chip add unprecedented computing power and bring significant performance boost.

Samsung's Qualcomm 835 also delivers gigabit speeds. But comparing iPhone X with Galaxy Note 8 and Galaxy S8/Plus, Apple has a colossal lead. As for the Samsung phones, Galaxy Note 8 is no doubt more powerful than Galaxy S8 with 2GB more RAM, which can have more apps in the memory, but that's not an obvious difference. But Galaxy Note 8 has an S Pen included, which allows some professional tasks like writing messages, annotating etc.

4. Face ID vs Fingerprint Sensor

* iPhone X - 3D facial recognition technologies
* Galaxy Note 8 - rear-facing and off-center fingerprint scanners
* Galaxy S8/Plus - rear-facing fingerprint scanners

In this round of Samsung Galaxy S8 vs Galaxy Note 8 vs iPhone X comparison, Apple is an easy winner. As mentioned above, the camera in iPhone X has a 3D scanning ability used to include an all-new "Face ID" feature instead of the Touch ID. The face recognition will be quicker, more secure, and more accurate than Touch ID. It's also easy to set up Face ID on iPhone X with just one look.

There is also face recognition in Note 8, but it's not so fantastic in Galaxy Note 8 vs iPhone X. Both Galaxy Note 8 and S8/Plus has fingerprint scanners, but located in weird awkwardly. The rear scanner on the Galaxy Note 8, Galaxy S8 and S8+ is tough to use consistently, while the off-central is still too far.

5. AI Assistant: Siri vs. Bixby

* iPhone X - improved Siri
* Galaxy Note 8/Galaxy S8/Plus - new Bixby

Samsung has its own AI-based digital voice assistant Bixby that comes built into the Galaxy S8 and Note 8 to compete with iPhone X' Siri. Siri has learned over time, and in iPhone X, there is a smarter Siri with improvements like a more natural voice, a new visual interface, its own button, translating ability etc. Samsung may lose this round of iPhone X vs Galaxy Note 8 vs Galaxy S8 comparison.

Bixby is promising, and it does things that Siri can't, particularly when it comes to controlling the phone. But it's inconsistently implemented and not as quick as Siri or Google Assistant.

6. Battery Life

* iPhone X - 2700 mAh
* Galaxy Note 8 -3300 mAh
* Galaxy S8/Plus - 3000 mAh/3500 mAh

Battery is a big difference between iPhone X, Galaxy Note 8 and Galax S8/Plus. Poor battery life is a long-standing complaint for iPhone and there are massive googling for iPhone battery life tips. iPhone X aims to solve this problem with a much larger battery. According to Apple, iPhone X has an additional two hours of battery life thanks to being more power-efficient with its new A11 Bionic processor and other updates

However, when compared iPhone X with Galaxy Note 8 and Galaxy S8/Plus, there is an obvious gap. The Note 8 packs a 3,300 mAh battery, slightly less than Galaxy S8 Plus' 3500mAh battery. But if you want to choose a phone that will last longer, you should also consider the enormous 6.3-inch 2,960 x 1,440 display in Galaxy Note 8, which will need a lot of battery to handle.

7. Operating System

* iPhone X - iOS 17
* Galaxy Note 8/Galaxy S8/Plus - Android 8.0 Oreo

Beyond the hardware, software is a key factor when you choose which to buy between iPhone X and Galaxy Note 8/S8/Plus. Both operating systems have something in common, like picture-in-picture, new emoji etc, and both have unique features that the other doesn't. For iOS 17, you can enjoy amazing ugmented reality, powerful new features for iPad, smarter voice assitant, and a slew of improved functionalities.

And on Android 8.0 Oreo, there is autofill framework for logins and passwords, battery life improvements, notification dots, suite of tools that helps to improve the performance and security named Vital and more. It's hard to determine a winner in this round.
