Let's compare the difference between Mi 6X and vivo X21 together to see who is better to buy these two phones.
Appearance comparison:
In terms of appearance, Xiaomi Mi 6X and OPPO R15 have obvious differences, including body material, body size, front and back design style, the overall difference is relatively large. The main similarities are the full screen and rear fingerprint design.
On the positive side, Xiaomi Mi 6X and OPPO R15 are both full-screen designs, but 6X belongs to the 18:9 full-screen that was popular last year, while OPPO R15 is the more popular 19:9 full-screen with bangs this year, with a higher front screen ratio. And the fuselage will be more slender.
On the back side, the Mi 6X is similar to the previous generation 5X, using a hidden U-shaped antenna metal back shell design, which is now a more traditional design. OPPO R15 adopts the glass body that has been popular since this year. There is no antenna line on the back, which is more concise. In addition, it also adds new technology, such as glass gradient, dream mirror effect and so on. The same elements on the back of the two are mainly the same as the rear dual camera and fingerprint sensor design.
Mi 6X is equipped with a 5.99-inch 2160x1080 resolution full 18:9 LCD full screen; OPPO R15 is equipped with a 6.28-inch 2280x1080 resolution 19:9 full screen Samsung AMOLED notch.
Performance configuration comparison:
Xiaomi 6X and OPPO R15 Dreamland Edition are equipped with Qualcomm Snapdragon 660AIE, the mainstream configuration in the mid-to-high-end market, while OPPO R15 is equipped with a P60 dual-core artificial intelligence chip that is worse than Qualcomm 660AIE, with the highest storage capacity of Xiaomi 6X and OPPO R15 6GB+128GB is optional. Xiaomi Mi 6X is very intimately optimized for the "Glory of the Kings Full Blood Edition" to enjoy the high frame rate experience while lower power consumption and less heat, which has taken care of many gamers.
Comparison of camera functions:
Both Xiaomi Mi 6X and OPPO R15 are the main camera phones. Mi 6X has a 20 million "curing" selfie camera on the front. It uses Sony's 20 million pixel sensor, which can intelligently synthesize 2μm super-large pixels. It can image very clearly in low light conditions. The rear of Mi 6X adopts 12MP+20MP full Sony photosensitive element configuration, which can intelligently select the main camera lens according to the light. 12MP is clearer during the day, and 20MP is brighter at night. The OPPO R15 front is also 20 million pixels, the OPPO R15 rear uses a 16 million + 5 million pixel combination, and the dream version of the OPPO R15 uses a 20 million + 16 million pixel combination to take pictures.
The system does this:
Xiaomi Mi 6X runs the MIUI 9 system, which is deeply customized based on Android 8.1. The advantages are high system playability, comprehensive functions, fast system update speed, and good reputation. The disadvantage is that the system has many built-in advertisements. OPPO R15 runs the ColorOS 5.0 system, which is deeply customized based on Android 8.1. The advantages are simple interface, few pre-installed apps, and no ads. The disadvantage is that the system update speed and functions are not very comprehensive.
How to choose Mi 6X and OPPO R15? If you are more price-sensitive, Mi 6X can be a thousand cheaper, bring the same performance, and other aspects such as taking pictures are also good, more suitable for users who pursue cost-effective recommendations. If you are not sensitive to the budget and pursue a better comprehensive experience, OPPO R15 will have a more obvious advantage in experience, and it is worth considering R15 at this time.
Bitcoin mining machines are one way to obtain bitcoins. Bitcoin is an online virtual currency created by open-source peer-to-peer software. Instead of being issued by a specific currency institution, and produced by the massive computation of a specific algorithm, the Bitcoin economy uses a distributed database of nodes throughout the P2P network to identify and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin by producing a large number of coins.
Any computer can become a mining machine, but the returns will be low, and it may not mine a single bitcoin in a decade. Many companies have developed specialized Bitcoin mining machines with special mining chips that are tens or hundreds of times faster than normal computers.
Currency system by the user (the user through the key control wallet), trade (trade will be broadcast to the whole currency network) and miners (generated by competition calculation agreed on each node of the chain block, block chain is a distributed public authority books, contains the currency network of all the transactions happened)
Bitcoin miners manage the Bitcoin network by solving the problem of proof-of-work mechanisms with a certain amount of work -- confirming transactions and preventing double payments. Because hashing is irreversible, finding the number of random adjustments required to match is difficult, requiring a trial-and-error process that can predict the total number of times. This is where the proof-of-work mechanism comes into play. When a node finds a solution that matches the requirement, it can broadcast its result to the whole network. Other nodes can then receive the newly solved data block and check whether it matches the rule. If the other nodes calculate the hash value and find that the requirement (the operation goal required by Bitcoin) is satisfied, then the data block is valid and the other nodes accept the data block.
