That is, on the afternoon of March 1, Xiaomi held a conference on pinecone chip in Beijing, and released the rumored first self-developed mobile phone chip S 1 (officially named).
In Xiaomi's mouth before? Black technology? Before, many people spoke out that Xiaomi was actually promoting other people's technology, and there were not many really independent designs. How many independent technologies does Xiaomi's S 1 contain? Can Xiaomi prove himself? Let's take a look at this 2855438+0 chip.
澎湃 S 1
Eight nuclear 64-bit processor with 28nm technology includes four A53 cores at 2.2GHz and four A53 cores at 1.4GHz. The GPU is a quad-core Mali-T860. In particular, Xiaomi said that S 1 chip supports intelligent prediction and switches between large and small cores in real time. What does this mean? Is it difficult to see seven cores with one core? The phenomenon will not appear, and both performance and battery life will be taken into account.
In addition, the S 1 chip also adopts the extensible baseband designed by Xiaomi, which is convenient for subsequent optimization. In addition, 2855438+0 also uses a 32-bit high-performance voice DSP, which supports VoLTE call and dual microphone noise reduction.
It is worth mentioning that 澎湃 S 1 also has a 14-bit dual-core ISP processor, which increases the image processing capacity, supports dual noise reduction optimization, improves the night scene quality, and makes the night scene photos more pure and delicate. Moreover, it also has a unique image compression technology, which can reduce the memory bandwidth occupation by 50% while lossless compression of images, while the power consumption can be reduced by 15% in dynamic image processing.
Running points on the spot
The comprehensive performance of 2855438+0 is equivalent to P20 in MediaTek. Of course, having said so much, the most intuitive thing about 2855438+0 is the score. According to the data given by Lei Jun at the press conference site, the running score is S 1 648 17 on the Antu Rabbit platform, which exceeds Qualcomm Snapdragon 625 and MediaTek P20 processors.
Generally speaking, as a newcomer in the chip industry, Xiaomi has achieved such a good level of processor for the first time, and there must be many improvements. For example, the current chip technology has reached 10nm. If Xiaomi can boldly adopt the newer technology, it will obviously make the performance go up a storey still higher. Of course, this is only 2855438+0, and Xiaomi should launch a flagship processor with higher specifications.
In addition to releasing S 1, Xiaomi also announced Xiaomi 5c, the first Xiaomi mobile phone equipped with this chip. Xiaomi 5c adopts all-metal body, equipped with 2855438+0 chip, 5. 15 inch display, 3GB memory and 64GB body storage. In addition, Xiaomi 5c is equipped with a12 megapixel camera with a large pixel of 1.25um, which has excellent photosensitive performance. Xiaomi said that with the implementation of the S 1 ISP algorithm, the sensitivity of the 5c camera has been improved by 150%, and it has excellent night shooting ability. In terms of selling price, the price of Xiaomi 5C is 1499 yuan, which will be on sale at 0: 00 on March 3.
In addition, Xiaomi also updated the Redmi series and launched a brand-new Redmi 4X mobile phone. Xiaomi said that the machine adopts flagship machine technology, but it still carries out the cost performance to the end. In terms of configuration, Red Rice 4X is equipped with a 5-inch display screen, a Qualcomm eight nuclear processor, a built-in 4 100mAh battery, rear fingerprint recognition and support for 4G full netcom. The price of 2GB+ 16GB version is 699 yuan, and the price of 3GB+32GB version is 899 yuan.
Self-developed chip
The significance of independent chips to Xiaomi Due to the decline of market position, independent chips are of great significance to Xiaomi. The data shows that the market share of Xiaomi China dropped to 16.8% last year due to the market squeeze of OPPO and vivo. Xiaomi's mobile phone shipments also dropped by 23%, accounting for only 8.9% of all mobile phone shipments in China. In the past, Xiaomi relied on Internet marketing to rise rapidly. However, as manufacturers such as Glory and Meizu joined the Internet marketing camp, Xiaomi's market share was divided, and OPPO and Vivo won most of the offline markets.
It is undeniable that the squeeze of marketing space is one of the reasons for Xiaomi's decline, but if Xiaomi wants to fight back, the core technology is the key. For example, OPPO's VOOC flash charging technology is the best example, and its latest five-fold optical lossless zoom technology is expected to attract a large number of consumers. As far as mobile phone chips are concerned, at present, only Apple, Samsung and Huawei in the world have independent research and development chips.
Lei Jun said that the chip is the commanding height of the mobile phone technology industry. As the most integrated chip, the mobile phone chip integrates 65.438 billion transistors, and Xiaomi can only gain a firm foothold by mastering the core technology.
It is not difficult to predict that after the launch of Xiaomi Guo Song chip, Xiaomi can reduce the pressure of purchasing mobile phone chips by itself, further reduce the cost and improve the profit rate. In addition, in the case that the domestic mobile phone market is saturated, the independent chip will pave the way for Xiaomi's overseas market development, because the main reason why Xiaomi's mobile phone has not landed in too many overseas markets is that it is restricted by communication technology patents. Besides,? Independent research and development? This title has always played an extra role in the sales in the domestic market.
