cloud network hunting note: 4 k high-definition screens, the improved performance of the CPU and GPU, and descending speed of up to 4 GBPS of wireless card device, qualcomm latest chip Xiao dragon 810 pretend bility of catching up the apple. But the company in product release is easy, the actual performance of the chip, need to be review.
international consumer electronics show is about to begin. But a few big electronics industry (apple, Google, Microsoft, etc.) are either going to publish the bombshell partial or don’t intend to attend the conference and exhibition. But we missed the big shot, consumption exhibition or still can be, also won’t disappointing – at least for chip manufacturers and the hardware provider, this is a great opportunity. Qualcomm is one, the company will be on exhibition flagship complete introduction in 2015 of a new generation of mobile phone chips: 810 Xiao dragons.
the chip preliminary design has emerged in April, but develop a complete chip often take years. Once the chips listed, Xiao dragon 810 will be fully replace the flagship mobile phone in 810 gm 805 chip. With curiosity and expectation of Xiao dragon 810, we have recently at a conference to qualcomm product introduction for nearly an hour, about how mobile phones will be carrying 810 chip performance. Long conference except to highlight the chip running speed, capacity, as well as the official launch time, but for we have learned content, we will tell.
Xiao dragon 810 issued by the parameter information in the second half of this year, still adopt the ARM architecture A53 CPU process.
since 2012, the introduction, chip Xiao dragon S4 qualcomm’s flagship chip has been developed using also is custom design company “Krait” CPU. But the company wants to change its development strategy, so have the Xiao dragon 810. Unlike Xiao dragon S4, 810 directly USES is produced by ARM processor, respectively, based on 64 – bit architecture A57 A53 and architecture. At the same time, in the chip design, USES four Cortex57 and A53 core of big. LITTLE architecture. Put forward by ARM to take the lead in this architecture, supports two different ways of processing, the Cortex A57 to high-performance process, and the Cortex A53 with general process. In theory, eight core processor can run at the same time, but no one actually used powerful to take up all the process at the same time. For the moment, qualcomm on chip processing speed silent, we also difficult to speculate that the Cortex A57 actual performance.
but from the current market situation and want to be the equal of apple and iOS ambitions, 64 chip stunt is important, as to the actual performance of it can hang on. This is also why qualcomm will resolutely give up bespoke experience devoted years of effort and a lot of money. If you miss once Krait, perhaps after a few years it will be back on the field of vision, but as things stand, on the one hand, qualcomm has no independent research and development of 64 chip technology, on the other hand, apple has introduced last year in the process of using 64 – bit CPU A7 chips, independent company to abandon traditional custom to adopt ARM the design of the finished product is obviously the most sensible decision in such a short time.
but in terms of graphics, qualcomm, always adhere to the principle of independent development, the Adreno GPU is series. Qualcomm said a new generation of Adreno GPU 430 compared with the original Xiao dragon used on 805, 420, almost 30% performance improvement, energy consumption is reduced by 20%. The original Adreno 400 series support the same graphic coding and GPGPU API, including DirectX 11.2, OpenCL 1.2, and OpenGL ES 3.1. On the resolution, Andreno support the maximum resolution of 430 and 420, and 3840 x 2160 pixels. Qualcomm think 4 k high-definition screens next year (horizontal resolution of 4000 pixels high definition screen) will become the mainstream of the tablet, appear in all carry Xiao dragon chip 810 tablets.
even so, we still have a lot of good faith as the personage inside course of study reminds everybody don’t carried away by a frenzy of propaganda. 4 k high-definition screens may bring large display qualitative leap, but with 2560 x 1600 pixels or 2048 x 1536 pixel screen, for most people, basic don’t feel any changes.
as for the wireless card, 810 will continue to support 802.11 (WLAM) communications standards, at the same time will also support the Cat 9 LTE, descending speed when the theory is expected to reach 450 MBPS (50 MBPS uplink speed remains unchanged). Another important innovation is 810 will take the lead in supporting “WiGig”, or 802.11 AD network, it is mainly used for home wireless hd audio and video signal transmission. Learned, “WiGig” abandoned the crowded 2.4 GHz and 5 GHz frequency band, and adopt the high frequency carrier of 60 GHz spectrum, theory of transmission rate can reach 7 GBPS (considering the mobile devices can carry the antenna number is limited, qualcomm promised the maximum transmission rate of 4 GBPS).
802.11 AD gradually popularize feasible, but instead of 5 GHZ wi-fi is a bit unrealistic. 802.11 AD there are still a lot of restrictions on technology: it relatively limited range of the signal, the signal of the penetration ability is poor. Its advantage lies in the signal transmission between domestic equipment, such as family television, set-top boxes, mobile phone and tablet relatively close to the distance between devices.
the last point is that 810 Xiao dragon will upgrade to 20 nm technology, become a qualcomm’s first adopt Taiwan semiconductor manufacturing co (TSMC) chip of the latest technology. 28 nm TSMC said, compared with the original process, using 20 nm process chip can reduce energy consumption by 25%. For chip manufacturers, however, this means that in the same under the situation of energy consumption, they have more space can be used to improve the performance of the chip.
in the product recommendation meeting, qualcomm did not disclose more details on the chip, would put a lot of emphasis on the hardware performance related to the chip.
conference, the company showed the mobile phone has a camera. Each camera lens are fixed but the focal length is not the same, the two lenses card photos taken through the special image processing software, mobile phones can simulate SLR camera shooting effect. The wonderful design is based on Corephotonics dual camera Settings. Earlier this year, the innovative design has appeared on the mobile world congress.
if reference prototype or HTC One M8 really can realize, we can expect to see a large number of dual lens in 2015 mobile phones will appear on the market. How to narrow the gap between mobile phones and professional camera, has always been a difficult problem. One solution is to get as much of the image data and the data together with post-processing. Any seemingly magic, of course, advanced technology, involve the king of the “innocent” apple. Before apple was transmission, are developing characteristics of graphics processing scheme.
the last notable new features is in separate operating platform directly forced closure process. Legislature has set out to establish relevant law requires smart phone support remote data cleansing and intelligent lock to prevent the data on the mobile phones are stolen or are stolen. Android, iOS, and other systems have related software to support this feature, but “Safeswitch” qualcomm are from another distinctive point of view – “hardware level” mobile phone users – giving and a full range of protection.
we can predict Xiao dragon 810 chip will appear in next year’s new flagship phones and tablets, samsung, HTC and other brand products are likely to take the lead in adopting the new chip. Apart from apple, qualcomm in high-end mobile phone market dominance is indisputable. If next year for mobile phone are you going to do, then you can consider starting with a carrying Xiao dragon chip 810 new phone.
