Eyeq4h computing power
recently, I saw a test that the rtx3070 notebook only earns 1.2 yuan an hour.
1050ti computing power is less than 1 / 4 of 3070, which is about 24%
power consumption is 35% of 3070.
energy consumption is not cost-effective. One hour's income is definitely less than 1 yuan, except for the electricity charge. Once the loss of notebook is eliminated, it is definitely a loss
but virtual currency itself has great risks

Although Europe is also affected by the epidemic, so far, the Geneva International Auto Show, which will open on March 5, has not officially announced plans to postpone or cancel. A number of auto instry giants, including Chinese auto companies, will still participate in the exhibition as scheled. Compared with previous years, this year's exhibition works of Chinese auto companies are of special significance, because the brand-new models equipped with China's standard level edge computing chips will soon appear at the auto show. This means that the competitiveness of Chinese automobile enterprises is no longer limited to the previous engine, gearbox, body, chassis and appearance. Instead, they are facing the higher level development of automobiles and the future of automobile development artificial intelligence. The bugler, the manufacturer of this car size edge computing chip, is horizon from China
horizon's mass proction of car level chips in the field of automatic driving is undoubtedly good news for China's automobile instry as a whole. It can be predicted that in the future, the demand for computing power in automobile and artificial intelligence instry is amazing. In the past few years, we have seen that every step up in the level of intelligent driving will increase the computing power by almost an order of magnitude. If we want to achieve full automatic driving, the vehicle needs thousands of top level computing power. However, the average computing power of procts in the current automotive market has not reached the top of single digit. Therefore, in the face of huge market demand, the strength of Chinese enterprises is very important. If we do not pay attention to this strategic highland, we may still be subject to overseas restrictions like aircraft engines and automobile powertrain. And the emergence of China's national power not only means that our strategic highland is expected to be held fast, but also may be able to capture cities and seize land in the world market. Some experts in the instry predict that the front loading capacity of Cheng Cheng chips will reach one million in two years and ten million in five years

nowadays, L2 level assistant driving system seems to be one of the indispensable highlights for all car companies to promote their procts, and it is true for both traditional car companies and new car manufacturers. But the same "help" driving function, some act like a novice driver, some seem to be able to directly "drive" for you
then why do the same functions show different strengths, and what are the differences behind them? Next, the chief travel officer will take you to understand the L2 level auxiliary driving function under different "configuration packages"
"standard package: hardware support for" one meat and one vegetable "
the standard package still appears more in the traditional car companies, especially in a number of domestic joint venture brand models
taking the latest Toyota RAV4 as an example, the manufacturer named its L2 level auxiliary driving function as Toyota safety sense intelligent safety system. It can realize the functions of active braking, adaptive cruise and lane center keeping, and can follow the track of the car in front of it. It belongs to the standard L2 level auxiliary driving function configuration
the supporting hardware to achieve the above functions is mainly millimeter wave radar and front monocular camera. Among them, millimeter radar is mainly used for real-time detection of the speed and distance of the car in front, realizing adaptive cruise and active braking functions (camera as auxiliary and rendant). The front monocular camera realizes the function of keeping the lane in the middle by recognizing the road markings and the driving track of the car in front
L2 assistant driving system is more to assist the driver to control the vehicle horizontally and longitudinally. The driver still dominates the control of the vehicle and does not need too much computing power. Therefore, this kind of "standard package" will not be equipped with higher-order computing chips
"standard package" is the most basic functional configuration. Both the hardware configuration at the perception level and the chip configuration at the decision-making level are just "enough", and the later stage does not have the ability to upgrade OTA to a higher level of automatic driving. The biggest advantage of such "standard package" is that the supply chain is mature enough, and its cost has been effectively controlled. Therefore, it is more applied to the "breakthrough" of traditional automobile brands in the field of intelligent driving
at the present stage, joint venture brands are the main brands. In essence, all kinds of "intelligent driving" systems, including Volvo's pilot assisted driving system, belong to the basic L2 level assisted driving function. On the one hand, each company has different naming methods, and on the other hand, it will optimize the algorithm. But all of them are inseparable from their ancestors
for such brands, the intelligent driving assistance function is just a icing on the cake configuration. At this stage, they will not invest too much research and development efforts. Their pursuit is "enough is good"
"luxury package:" intelligent driving with four dishes and one soup "
compared with the standard package of traditional car companies, it is the" luxury package "of intelligent driving of new car makers, commonly known as" stacking material ". Especially for the new car making forces, which are known as "self-developed" automatic driving ability, if they want to challenge Tesla, they must be able to match the ability of the latter two years ago in terms of automatic driving ability. It's too late to learn its simple vision scheme, and the best way is to work hard on sensor fusion
Weilai automobile is one of the car companies with "luxury package" as standard. Although the ES6 and es8 launched by the company can only realize L2 level auxiliary driving function at the present stage, they have deeper development potential in hardware configuration
in terms of hardware configuration at the perception level, Weilai's car is equipped with one three eye camera, four panoramic system cameras, five millimeter wave radars, 12 ultrasonic radars and one driver status detection camera. Among them, three eye cameras and five millimeter wave radars are mainly used for perception of auxiliary driving function
the front three eye cameras developed by Weilai are 28 degrees, 52 degrees and 150 degrees respectively. Among them, the 28 degree camera is used to identify long-distance targets and detect traffic lights; The 52 degree camera is used to identify the road conditions; The 150 degree camera is mainly used to scan both sides of the front of the car and the congested vehicles. Compared with the "standard package" monocular camera, its biggest advantage is that it can recognize more information, so that the vehicle can see the surrounding environment more clearly. Secondly, it is used as hardware rendancy to ensure the normal operation of the function when a single camera is blocked or damaged
in addition to one front-end for adaptive cruise function, the five MMW radars are also arranged in the four corners of the car body for data acquisition of blind area detection and lateral vehicle warning function
in addition, Weilai has a higher level of automatic driving ability, so the decision-making level is also equipped with a more powerful Mobileye eyeq4 chip, whose performance can meet the top floating-point computing capacity of more than 2.5 trillion times per second. In the introction of Mobileye to its q-series chips, we can see that the eyeq4 chip can meet the computing power requirements of L3 level automatic driving function
"luxury package" hardware configuration, in essence, has gone beyond the basic requirements of L2 level auxiliary driving function, is to lay a "foundation" in advance to achieve a higher level of automatic driving ability. Compared with the "standard package", the "luxury package" is far more powerful in terms of both the perception hardware configuration and the computing power performance of the chip, so it is more than enough to realize the L2 level auxiliary driving function. Obviously, the new car building forces who put the OTA capability of the whole car in the beginning of the proct definition have more imagination about "growth". Unlike the "standard package", the functions of the whole proct cycle may not change much from the beginning of delivery
"flagship package: the automatic driving of Manchu and Han people" strictly speaking, Tesla is the only car company carrying the "flagship package". After all, the Tesla car equipped with FSD chip has met the hardware capability of automatic driving
in 2019, Tesla released a fully self-developed FSD chip, which realizes about 144 trillion tops floating-point operations per second, and can meet the computational performance of fully automatic driving. The computing power of the FSD chip developed by Tesla is nearly seven times that of NVIDIA Xavier. Its unique neural network can process the image data generated by eight cameras at the same time, and has the ability of self-learning and evolution
secondly, in terms of perception ability, Tesla has also chosen full visual perception configuration. Tesla's visual recognition system has a wider range and more accurate types of road traffic participants. Through multiple cameras, Tesla's three cars in mass proction can provide 360 degree full coverage around the vehicle. Not only for the vehicle lane, but also for the left and right lanes. In addition to a wider range of recognition, Tesla's ability to recognize objects is also far stronger than other car companies. According to the experience of the chief travel officer and the videos uploaded by other car owners, Tesla can distinguish between pedestrians, ice cream cones and even horses on the road in addition to identifying cars, trucks and buses
the most "terrible" part of Tesla lies in its creation of "shadow mode", which enables every Tesla car on the global road to upload daily driving data for the research and development of the company's intelligent driving function, and promotes the continuous evolution of its artificial intelligence algorithm based on multilayer neural network through richer driving data. According to the published data, Tesla has collected more than 17 billion kilometers of real driving data, of which more than 1.6 billion kilometers are driven by Tesla's autopilot intelligent assistant driving system
"flagship package" is not only the consideration of hardware configuration, but also the requirement of decision-making and execution ability of the system itself. On the basis of this dimension, to realize L2 level auxiliary driving function is really not too much to describe as "big horse pulling small car"
"finally"
in fact, the "standard package" of traditional car companies can well meet the basic functions of L2 auxiliary driving system such as ACC and LKA. While the "luxury" and "flagship" packages realize richer functions and more practical experience
especially for the model equipped with "standard package", the so-called L2 auxiliary driving is nothing more than a "help you drive" function, which can indeed rece the driver's physical fatigue to a certain extent. The "luxury package" and "flagship package" give drivers a more relaxed driving environment, and even it's not a big problem for the driver to take a short drive. However, their greatest value lies in the potential of later OTA to a higher level of automatic driving
from this point of view, if you are an automatic driving enthusiast, I'm afraid a Tesla, Weilai or Xiaopeng is more suitable

The reason why Xiaopeng P7 can be the strongest competitor of Tesla Model 3 is that it also shows a number of high-quality capabilities in the field of traditional electric car racing. The first is its chassis. Xiaopeng automobile and the top German team jointly developed the p7 chassis, and used Bosch intelligent brake control, bramble brake system, Ningde era high energy density battery, front double wishbone + rear five-bar independent suspension, ibooster intelligent brake, intelligent continuous active damping system and high-performance three in one electric drive, The top hardware makes P7 a pure electric vehicle with the longest comprehensive range of NEDC up to 706km, 100km acceleration of 4WD version 4.3s and 100km braking distance < 35m. And I also heard that P7 has excellent NVH performance, and it is equipped with Dana Dynaudio theater level concentration sound system, and its unique ceiling sky channel, which brings immersive experience of 3D surround, intelligent dynamic balancing technology, vehicle music surround sound field control technology, and more realistic reproction of the stage scene in the car, so that each position is C-bit. In addition, P7 has passed the five-star safety standard, IP68 waterproof and stproof battery pack and B-pillar side impact enhancement, xfreebreak intelligent air purification system, independent information security mole PSO and 360 ° Real time perception of active security early warning system and other hardware and functions to achieve passive security, battery security, air security, information security and active security five major security protection. It's not unreasonable to dare to challenge Tesla Model 3 for a car with technology, intelligence, safety and price advantage
On November 13, Zero run car is your AI smart chip friend & quot; Lingxin 01 & quot; I sent a confession on my micro blog
The confessions ofare expanded in the form of long graphs and expressed as & quot; I'm afraid you'll be embarrassed if you don't know this friend; I have made a detailed introction to myself
According to previous data statistics, from the current situation of the development of domestic automatic driving chips, domestic car chips do not occupy a large market space, and the domestic car chip autonomy rate is less than 10%. This kind of market situation is undoubtedly beneficial to & quot; Lingxin 01 & quot; The future promotion of the Internet has caused a lot of pressure However, no matter what, zero running makes & quot; Lingxin 01 & quot;, It can also be regarded as the opening of China's independent intellectual property rights vehicle specification level intelligent driving chip & quot; New era & quotand why & quot; New era & quot; It's not Weilai, ideal and Xiaopeng who have better sales, higher market value and more financing. It's not important anymore

A series of partners of horizon in the field of intelligent vehicles
from the perspective of horizon's proct layout, it has the feeling of global visual ADAS oligarch Mobileye
However, from the perspective of market play, the horizon is much more flexiblethe eyeq series chips on which Mobileye is famous also have embedded sensing algorithms, but when it sells its procts, it often packages the software and hardware, and does not make targeted modifications according to the customer's situation, or let the customer's algorithms run on its own sensing chips
and horizon gives a completely open way to play, which can provide both hardware and overall solution including algorithm, and also provides customers with a complete tool chain called Tiangong Kaiwu to adjust and optimize the algorithm on the chip
for example, SK Telecom uses the crowdsourcing high-precision map scheme provided by horizon to collect high-precision maps, but the algorithm does not support the recognition of Korean road signs. Finally, horizon provides a tool chain for SK Telecom to increase the Korean recognition ability in the algorithm, and finally completes the deployment in Korea
it is this high degree of openness that enables horizon to obtain customers of all types from all regions of the world
when understanding the service advantages of horizon, Zhang Yufeng mentioned a small story about the hardships of crossing the Pacific Ocean
} horizon's journey series chips and moles
in 2018, a top automatic driving company in the United States is trying horizon's matrix platform, which inevitably leads to some adaptation problems. At that time, horizon had no branch office in the United States, in order to solve problems for customers in the first time
a team of engineers from China flew to the United States almost every other week to help them solve all kinds of bugs in great detail, and finally help them realize the rapid deployment of unmanned vehicles
"it is this high-quality service across the Pacific that makes this autopilot company finally decide to adopt the matrix platform." Recalling the hardships before, Zhang Yufeng's words also showed the joy of victory, "the new generation of customer models, decided to use our platform."
now, although horizon has set up an office and technical team in the United States, there is no need for Chinese engineers to provide technical support to customers across the ocean, this high-quality service tradition is still preserved, which is one of the three magic weapons for horizon to achieve landing results
conclusion: automatic driving chip war upgrade? Horizon has won a phased victory
with the increasing popularity of automatic driving technology, the demand for automatic driving chips will continue to rise in the future, causing the layout of more giants and the rise of start-ups
NVIDIA, Qualcomm and other consumer electronics chip giants have launched a new generation of autopilot chips and computing platforms, orin and snapdragonride, respectively; Denso and Toyota set up a semiconctor joint venture to focus on autonomous driving chips, Bosch built a new semiconctor factory, Huawei launched the MDC computing platform, and a number of start-ups emerged
there is no doubt that the chip war in the field of intelligent vehicles will become more and more fierce and cruel, and whether it can survive or not is a key factor of mass proction
according to the news released by horizon this time, it has made a series of key progress in the fields of ADAS and high-level automatic driving - more than a dozen Tier1 have become partners with auto companies, and it is a double-digit front loading project
as an AI chip player who has emerged since 2015, horizon at this stage not only maintains its position as a leader of AI chip makers, but also far surpasses other competitors at the same level in terms of landing progress, and even dares to challenge large consumer electronics chip giants directly
with this wave of smart cars, after more than one million chips will be loaded in 2022, horizon will grow from a unicorn enterprise to a small car chip giant, and enhance China's competitive strength in the field of car chips as a whole
