BGR has an informative write-up listing many of the new state-of-art features for the  Samsung Galaxy S8 and Galaxy S8+ as follows:

It’s funny how you can know just about everything there is to know about a new flagship smartphone thanks to rumors and leaks, and yet still be blown away when the phone is finally announced. Once people actually saw the full Galaxy S8 and Galaxy S8+ picture come together on stage yesterday, however, they knew they were watching something special.

1. Design — We can already state conclusively that these new flagship smartphones are the sleekest, most elegant, best-designed handsets the world has ever known. Just a few short years ago, Samsung was still releasing flagship phones made out of thin plastic that felt flimsy and cheap. Fast-forward to 2017 and the company’s new Galaxy S8 and S8+ are unmatched. Apple’s iPhones have always been considered the gold standard of design — they are the most copied handsets on the market, after all — but Samsung has bested Apple in every way.

2. State of Art Screen — First and foremost, Samsung’s new Galaxy S8 and Galaxy S8+ have narrow bezels and a screen-to-body ratio of 83%. As a result, Samsung has fit a monstrous 6.2-inch Super AMOLED display into a phone the same size as Apple’s 5.5-inch iPhone 7 Plus. Then you’ve got the rounded edges on the front and back of the phones, which makes them fit perfectly in the hand. It also makes Samsung’s new phones feel incredibly thin despite actually being a tiny bit thicker than Apple’s iPhones.

3. Bixby — The second most talked-about Galaxy S8 feature has to be Bixby. This is Samsung’s attempt to combat the rise of digital assistant products like Amazon Alexa, Google Assistant, and the one that started it all, Apple’s Siri. This is one of the hottest spaces in consumer tech right now, so it’s no mystery why Samsung would want in on the action.

4. Bixby Vision — Bixby Vision is an extension of Bixby that brings the physical world around you into the picture. Literally. Using the camera on the Galaxy S8 or S8+, Bixby Vision allows the phones to “look” at their surroundings and offer useful information to users. Bixby Vision can also “see” printed text and instantly translate more than 50 different languages.

5. Samsung DeX — Samsung isn’t the first company to bake a desktop experience into a smartphone, but it is the first company to bake a desktop experience into a smartphone that people actually want.  Samsung’s implementation with DeX is shockingly fast.

6. State-of-Art CPU Processors — The processors are more important than normal because these are the first new smartphones to sport next-generation 10nm chipsets.The Qualcomm Snapdragon 835 and Samsung Exynos 8895 use a process that is more compact than any other mass-market processors. They’re also more energy-efficient and more powerful than any other processors on the market. In terms of multi-core performance, they absolutely crush everything else on the market and people are excited to check them out.

7. Bluetooth 5.0 support — Galaxy S8 will be the first widely available smartphone with Bluetooth 5.0. This next-generation wireless technology is better than current versions of Bluetooth in literally every way. It’s more power efficient, it has four times the range, and it supports two simultaneous independent streams.

8. Gigabit LTE capabilites — Galaxy S8 will be the first phone to support gigabit LTE speeds. That’s right, 1Gbps data transfers on your phone. Google luck holding onto your tiered data plans in the future
