Note 20 Ultra remains faithful to the square design, 6.9-inch Dynamic AMOLED 2X borderless screen, HDR10+ support, 120 Hz refresh rate to help display images smoother, reducing slight jerks when transitions use. It would be a huge omission if not to mention the S Pen, the new version feels more real and responds faster (9 ms). The feeling of writing is also more real, similar to when you are writing on the surface of paper. The back of the device is a large camera cluster with a main sensor of up to 108 MP, a 12 MP super wide-angle sensor, a 12 MP telephoto camera, supporting optical image stabilization. Meanwhile, the selfie camera has a resolution of 10 MP, placed inside a “mole” on the screen. Note 20 Ultra costs only 17.9 million.

The battery of the device has a capacity of 4,500 mAh, supports 25 W fast charging (30 minutes to charge 50% of the battery). Another feature on the Note 20 Ultra is Samsung Dex, which supports wireless connections with other devices. The product is currently being sold in three colors white, black and copper with a price of 17.9 million VND for 8 GB RAM version, 256 GB internal memory, down nearly 12 million VND in less than a year. Besides, some mid-range Samsung products are also being discounted by 1 million dong in June 2021, such as Galaxy A32, A52 and A72. These three products are being discounted by retail stores to VND 5.4 million, VND 7.59 million and VND 9.69 million, respectively.

IBM’s 2 nm chip had a density of 333 million transistors per square millimeter. By comparison, TSMC’s most advanced chip with a 5 nm process has about 173 million transistors, while Samsung’s 5 nm chip is 127 transistors per square millimeter. Billions of transistors are found on each microprocessor, and the size of the transistor is measured in nanometers. The smaller the size, the more transistors the processor can hold, making it faster and more energy efficient. IBM successfully built a chip with a size of only 2 nm but the most powerful in the world. Most of the processor chips found on personal computers or smartphones today are manufactured using a 7 nm or 10 nm process. For example, the 7-nm Apple A13 Bionic chip has 8.5 billion transistors. Meanwhile, the A14 Bionic microprocessor manufactured on a 5 nm process is integrated with 11.8 billion transistors. More transistors on a chip give manufacturers more options to deliver core innovations, to improve performance for leading tasks like AI and cloud computing, and pave the way for security. Cryptography and encryption are hardware-enforced. The need to increase performance and save energy in every processor has never cooled, especially in the era of the cloud, AI and IoT. The 2 nm chip technology is estimated to achieve 45% higher efficiency, 75% lower energy use than the advanced 7nm chips currently on the market.
