How smart 28 months phone set up can now xyumy answered him. Li Jun told us at the press conference: Xiaomi’s first chip, the Rising S1, is an octa-core chip, positioned mid-height, and rivals Qualcomm Snapdragon 625 and Media Tech Helio P20, The modem (modem, communication module) points to direct independent research and development, CPU, GPU, DSP, ISP none … Although there are no obvious bright spots, it seems There should be a lot of them, and they look relatively “stable”. So, for such seeming “sound” as Xiaomi Songgo Rising S1 (hereinafter referred to as “Rising S1”), what did Lei Jun not reveal at the press conference?
1. CPU-28nm Snapdragon 625, Helio P20
Smart phones are now being upgraded to 10nm higher than 14nm, and the rising S1 28nm selected as the “mid to high end” option. Consider that HSC + is the latest product of TSMC’s 28nm process. Compared to the previous 28nm, it resolves the leakage problem better and ensures better battery life. However, it is 28nm instead of the more advanced 20nm. Not 16nm, 14nm, or even 10nm – lower values, the higher the production process, the higher the accuracy, and the lower CPU power consumption.
Xiaomi’s comparison with Snapdragon 625 and Helio P20 can be easy to understand.
Snapdragon 625 uses 14nm LPP, and HelioP20 uses 16nm fan FET. By the numerical changes above, we can see the increasing geometry of S1. From that point of view, is Lee Jun’s growing S1 saying that “achieving the best balance of performance and power consumption” is a bit much?
2. Still CPU how to balance heat and performance?
The Rising S1 is an eight-core chip, based on the ARM big.LITTLE architecture, with both large and small cores present, both of which are Cortex-A53. Central frequency is used to distinguish large and small cores. The larger cover is 4 * 2.2GHz and the smaller cover is 4 * 1.4GHz.
The Snapdragon 625’s CPU is also designed for the eight-core Cortex-A53, and the central frequency is evenly distributed. The eight cores are all 2.0 GHz. The Helio P20 is also an eight-core Cortex-A5, with a maximum frequency of 2.3GHz. The advantage of high clock speeds is high performance, and the disadvantage is that it is more at risk of heat. How to choose the balance between different manufacturers, different manufacturers have their own opinion, and the real difference of experience on the real machine. Depending on, there is no further diagnosis.
3. Comprehensive performance points – just a doubt
Xiaomi announced a comprehensive running chart at the press conference, showing that the rising S1 is better than the Snapdragon 625 and the Helio P20. While this is really the case, we also provide ZL performance ladder diagram data for your reference here. There are some differences in the data that can be viewed and, according to xyumy pp numbers on the TV, it can be seen that antu 6.0 older version uses . Here we show the Running Score data of Antoine 6.2 and above, so here I am also waiting for the results of Xiaomi Mi 5s running with Antoine 6.2 and above . From a parameter perspective, the error factor can be much larger.
4. Modem – No full net work, almost exclusively for mobile
Currently, there is an absolute headline on the Qualcomm modem. Apple uses Qualcomm’s modem and Samsung in the world mainly because the modem will also primarily promote the Snapdragon processor version. Face to face. Did any “Big Boss” Xiaomi solve it easily? Obviously it won’t be that easy.
Careful people will find that the PPT final press conference Summary Page relatively ue vaguely zyumy MI 5 of the “Mobile 4G Edition” is marked with . In this regard, Lei Jun did not give much introduction to the details of the modem. Of these, Surgeon is actually the S1’s biggest helplessness.
On the one hand, it is difficult to say whether the signal is good or bad, on the other hand, it is still difficult to support Unicom Telecom 4G. It also has links to Linux technology. The source of the Xiaomi S1 chip technology is mobile, so it is still difficult for Xiaomi phones with extra chips to support Netcom or even support Telecom or China Unicom . Regarding the actual experience of telecommunication and Inicom card insertion, the author has not had the opportunity to measure them, but the Xiaomi conference site staff said that “only 2G can be used to insert Unicom cards.” ۔
In comparison, Snapdragon 625X9 is equipped with LTE modem, supports LTE Cat 7, uploads 2x20MHz carrier accumulation and supports 64-QAM , speed can reach 150MBS , download Load supports 2x20MHz carrier storage, speed can reach 300MBS, supports 3G, 4G full network, mobile, telecommunication, no need to consider China Unicom issues.
Although it is difficult to compete with Qualcomm on a MediaTek modem, the Helio X20 can also support LTE-TDD, LTE-FDD, and LTE-Cat6.
5. Compatibility – Many “rat” tests are needed immediately
For a new chip, heat output and compatibility are the main issues. You can know from the PPT at the Xiaomi Conference that the first time the Rising S1 runs through Android, and now 18 it is difficult to predict directly whether these issues can be resolved in a month, and Use only Huawei and Intel problems as a reference – Huawei’s first smartphone chip developed in 2008 after years of research and development. It was not actually used for commercial use. By 2012, Haselcon’s 3v2 began to be used commercially, but there were still heating and compatibility issues. Intel, a leading player in the mobile phone market, also made efforts in the mobile market. Unfortunately, for many years Despite efforts, it was still over. A compatibility issue. Such a problem was not clearly resolved in the short term before the swallowing Xiaomi Is. Comrades still need to work hard.
6. Millet – and yuan behind the difference of 100 yuan
Finally, look at the difference between Xiaomi’s own product and its own product. Xiaomi Mi 5 uses the standard Snapdragon 820 processor, priced at 1599 yuan, Xiaomi Mi Chip Surfing S1, although its purpose is Snapdragon 625, it is still priced at 1499 yuan. There are also “generation gaps” between Snap Dragon 820, Snap Dragon 625, Snap Dragon 650, Snap Dragon 652, Snap Dragon 653, Snap Dragon 810, etc. Arrive at 143887.
Is there such a performance gap behind the small difference of 100 yuan? Is it reasonable that Xiaomi deliberately increases the price to force a “mid-to-high” position? Is there a situation in which users are required to pay R&D by default? Question mark, do not evaluate too much here, consumers have the right to know, they can decide for themselves.
