What makes Apple famous is not only the iPhone, but also the iPad. The popularity of tablet computers also relies on the development of the iPad. The various brands of tablet computers currently on the market are all products that imitated and followed the trend after seeing the success of the iPad. iPad products are not only the first generation, but also the second generation, third generation and so on. iPad 3 is a tablet computer launched in 2012, when Apple was at its peak. So how much does iPad 3 cost? Many people are concerned about its price.
How much is iPad 3? 3388 yuan (last market quotation)
Appearance design
The word "new" for the new iPad does not apply to the appearance. The third-generation iPad completely follows the appearance design (and packaging box) of the iPad 2 design), it still has a 9.7-inch screen, a flat back design and slightly curved sides. When the two devices are put together, no difference can be seen from the front, back, or side. Because of this, the Smart Cover, originally an accessory for the iPad 2, can still be used normally on the new iPad.
In fact, there are still slight differences between the appearance of the new iPad and iPad 2. First, compared to the 8.8mm body thickness of iPad 2, the new iPad is about 0.6mm thicker. But this little difference cannot be clearly seen even if the two iPads are placed side by side. In addition, the new iPad weighs about 50g more than the iPad 2. In actual use, this difference can only be felt slightly by holding it up with one hand. Of course, it may just be a psychological effect. Second, compared toBelow, the camera of the new iPad is obviously larger than that of the iPad 2.
Hardware
The third-generation iPad uses the A5X SoC chip. It is easy to see from the name that its basic architecture should The same dual-core A5 processor used in iPad 2 and iPhone 4S. The biggest improvement of A5X is the 4-core GPU. Apple officially claims that A5X is a chip specially designed for Retina Display, which improves the image floating point performance to 32GFlops. The theoretical data is 4 times the performance of the NVIDIA Tegra 3 chip commonly used in other tablets, but no actual test data has been released yet.
The CPU of the new iPad is the same as the iPad 2 at 1GHz, while the memory has finally been increased from 512MB to 1GB. However, the overall score of the new iPad is the same as that of the iPad 2 and does not exceed the previous generation. In actual experience, the speed of the new iPad is indeed comparable to the iPad 2. Of course, this does not mean that the performance of the new iPad is not strong. Whether it is closing or switching programs, the new effect is very smooth and there is almost no delay. But when opening some large games, the new iPad is faster than the iPad 2, and it doesn't suffer from the occasional freezing problem on the iPad 2.
The significant improvement in resolution and GPU will inevitably lead to an increase in power consumption, and 10 hours of use time has always been the pride of the iPad. In order to maintain this pride, Apple decisively increased the battery capacity of the new iPad by 70% to 42.5 watt hours. The official data is 10 hours of usage time and 9 hours of 4G Internet time. In actual use, the screen brightness was set at about 80%, and the automatic brightness adjustment was turned on. More than 5 hours have passed since it was fully charged. After various twists and turns on the 4G network, 42% of the battery is left. The battery life has not been reduced, the battery life is still impressive, and the sacrifice of 0.6 mm thickness is still very worthwhile. However, the significant increase in battery capacity also brings about an expected problem: compared with the previous two generations of products, the new charging time is significantly longer.
Retina Display
Since the iPhone 4 was equipped with the high-definition Retina Display, there has been evidence such as high-resolution icons showing that iPad will also support Retina Display. However, this most requested change has been postponed on iPad 2. A year later, Retina Display is finally on the new iPad. The new iPad supports 2048×1536 resolution, which is four times the original 1024×768 resolution and even higher than 1080p full HD HDTV. To be honest, the new iPad is not a Retina Display in the strict sense, because when the iPhone 4 was released, Apple defined the Retina Display as a pixel density of 326ppi per inch, while the new iPad is 264ppi. However, due to normal use, the distance between the eyes and the iPad (more than 15 cm) is larger than the distance between the eyes and the iPhone (more than 10 cm), and on the 9.7-inch screen, the 2048×1536 resolution has exceeded what the naked eye can distinguish To such an extent that you can’t see pixels like color blocks, so we still call the new iPad’s screen Retina Display.
Camera
The new iPad is finally equipped with a 5-megapixel iSight rear camera, which supports auto-focus, auto-white balance and up to Face recognition of 10 people. The iSight camera also uses the same 5-piece lens design as the iPhone 4S, with an infrared filter added between the sensor and the lens, and a large aperture of f/2.4. However, there are also some problems. The new iPad is not very capable of expressing black, making black appear bluish. Compared with the iPhone 4S's photography performance, it can be clearly seen that the electronic processing effect results in a loss of more details in dark parts and obvious noise. In addition, due to the limitation of pixels, it is not very ideal to view the photos taken by the new iPad in full size.
Voice input
The new iPad did not bring Siri to everyone in the end, but it broke off a small part of it and made a dictation function for voice input. There is a new microphone icon in the lower left corner of the keyboard (the same as the one on the iPhone 4S). Press and hold the icon to perform voice input. The author casually said a few words for testing. It is still Nuance's technology and it still has a high degree of recognition.
How much does iPad 3 cost? Since iPad 3 was discontinued in 2013, and there was no supply, new iPad 3 has not appeared on the market. Naturally, there is no market for it now. If they are sold on the market, most of them are refurbished or second-hand products. The current price is below 1,000 yuan. If the price is higher than this, consumers are not recommended to buy it. Buying new iPad products may only cost 3 or 4 yuan. Why spend more than a thousand yuan to buy a tablet computer from 4 years ago?
