The Xbox360 disassembly was very smooth, and two minutes later, an iron circuit board was revealed in front of everyone, and the surrounding engineers were all around, and the best position was stopped by Yang Yun and Fang Hongsheng, who were carefully analyzing and explaining the various important modules.

Microsoft's single-65nm CPU technology is not mysterious, with a 27.8% improvement over the 90nm process used in the previous version of the Xbox 360, and the distance between each transistor has been reduced from 90nm to 65nm, which means that the 65nm process can integrate more transistors on the same size silicon wafer and process faster.

Now IBM's 65nm chips can be mass-produced, and the 45nm technology under development will be the first to be applied to Microsoft Xbox360 on a large scale in the near future, which is the news revealed by Microsoft itself, and the Longteng intelligence department has gotten confirmation from IBM internally, which is true.

Yang Yun saw a 20-piece high thermal conductivity heat sink integration group, coupled with the north and south bridge heat dissipation group that seemed to be quite efficient, and couldn't help nodding secretly.

It can be seen that in order to avoid the frequent occurrence of the three red problems, Microsoft has thought of a lot of ways to dissipate the CPU, at least these groups of heatsinks are made of the best aluminum alloy, the thermal grease connected to the CPU is also combined with a large copper medium, the amount of copper material is more than the general ordinary cheap heat sink, the cost price is much higher than that of all-aluminum alloy, and then look at the price of the host is not high, it does seem that Microsoft is full of sincerity.

"Look at the difference between the A version and the dual 90nm old version, mainly in terms of integrated circuit board route trend and CPU heat dissipation. You can observe these welds. There is also a socket that has been changed from the old version, and the USB has been changed to one. The network cable port is retained, and the position of the video VGA cable and HDMI interface has changed slightly. I'm guessing it's to facilitate the cooling of the case......"

Fang Hongsheng held a Phillips screwdriver and pointed at the circuit board, although the audience was much higher and more experienced than him, but the young man was not afraid at all, on the contrary, he unreservedly spoke about his in-depth research on different versions of the Xbox 360 series, which was unanimously praised by everyone.

"This fixed memory is a 256M modern memory chip, which is different from the previous dual 90nm. And on the graphics GPU, the A version still uses 90nm technology. There is no difference from the previous double 90 version, so I dare to conclude that if it can really solve the previous three-red problem, Microsoft's biggest improvement is still in the overall heat dissipation of the circuit board! Fang Hongsheng said at the end.

Everyone nodded and praised him.

"Xiao Fang is right, look at this white chassis shell, the air outlet is not the same as the old version, they must have redone the overall design of the chassis."

"Just do a start-up air duct and wind speed test later. Theoretically, a 65nm CPU does reduce energy consumption and heat a bit. ”

"It is impossible to completely eliminate the three reds with only one CPU, and the current games are more complex than the other, and they are all pursuing high-definition movie effects. GPU is a big heat dissipator, which is why Microsoft does not dare to package tickets to eliminate 100% of the three reds! ”

Yang Yun is also nodding in agreement, he knows the subsequent version of Xbox360. The A version of the single 65 is followed by the double 65, that is, both the CPU and the GPU become 65nm technology. Then there is the double 45, which is the slim version that players can rest assured of. If this is true history, then it was only in the double 65 era that Microsoft's three reds became extremely rare, and in the single 65 era, there were still many problems with the three reds.

"Hehe, Bill Gates, don't blame me for being ruthless, your single 65 machine is not bad, don't think that a Kinect can compete with me, as long as you can't solve the heat dissipation problem, the nightmare of Sanhong will always haunt you!"

Yang Yun put his mind at ease, the corners of his mouth were slightly upturned, he didn't worry much after dismantling the machine, it was still the same sentence, it was not that Long Teng was impeccable, but that the competitors were too stupid and made mistakes again and again!

Next, everyone began to test the air duct again, Fang Hongsheng tilted his head next to him and watched his father's movements without blinking, Fang Jindong did it himself, he carefully pasted a thin layer of smooth metal plate in the chassis box, which integrated special induction components to feel the wind, hide the small wires, and then install the box, and after turning on the computer, monitor the computer to check the air circulation.

Obviously, Microsoft modified the interface of each output of the circuit board, fine-tuned the position of the heat dissipation port, it must have been designed through a series of air circulation, but the model of Longteng and Microsoft's zuò is absolutely impossible to be the same, under the supervision of Longteng engineers, this A version of the box that has been reviewed by Microsoft and passed guò, there are still three places that do not meet the requirements of Longteng.

This is also one of the important reasons why DC2 rarely freezes and auto-restarts, and Xbox360 always likes Sanhong.

Fang Jindong turned off the monitoring in time, he didn't want his side to calculate an improved version, and accidentally someone revealed it and sold it to Microsoft.

"It's kind of interesting! It seems that the wind tunnel model research project jointly established by Tsinghua University and us is still different from the ideas of foreign designers! One programmer laughed: "And it seems that we have better experience with small models than their foreigners." ”

"That's it! The upgraded DC2 did not crash on a large scale, much stronger than their Microsoft frequent outbreaks of three reds, who said that we Chinese are inferior to foreigners in aerodynamics? The other laughed.

"Lao Zheng, don't you want to be so narcissistic! Knowing that your brother is in charge of this project, don't be so boastful, okay? You're so sensual! ”

"Haha!" Everyone in the dismantling workshop laughed, and a small chassis can show that the aerodynamics are ahead, which is indeed an exaggeration.

Already having a number in his heart, Yang Yun said: "Everyone has seen it almost, in the Near East, you first arrange someone to do a durability and violence test, you come with me, let's have a short meeting." ”

In a small conference room in the R&D center, Yang Yun looked at the other three people and said, "To deal with this A version of Xbox360, I want to launch DC3 now, do you have any problems in the Near East?" ”

Fang Jindong frowned, and his face was a little surprised: "Mr. Yang, according to the plan, DC3 should be launched at the E3 exhibition in March next year, five months in advance, will it be too rushed?" ”

Yang Yun shook his head: "This is a strategy, the listing news can be released in advance, the system parameters and configuration can inform everyone, the real listing time I plan to arrange for New Year's Day, and now you can produce and distribute." Is there a problem on your side? ”

Fang Jindong shook his head: "I have no problem, DC3 has been tested, in the original development plan, a buffer of 6 months was originally reserved, even if it was launched last month, I am confident." ”

"Backward compatibility testing is fine?"

"Yes, DC3 is compatible with DC2 and DC1 games, which you made eight years ago, and if it weren't for backward compatibility, we could shorten the development cycle of each new version to 3 years, in other words, DC4 we could have produced in 2010."

Yang Yun breathed a sigh of relief, the compatibility problem was the most criticized of all the video game consoles he knew.

In the Sony PS era, there was a lot of controversy, PS2 can be compatible with PS1, PS3 used to be compatible with PS2 on some thick models, but if you want to read the PS2 game disc with a gò optical drive, you have to go to Sony's official download emulator to play PS2 games with PS3, in short, it is very troublesome.

In the PS4 era, even the CPU was abandoned and replaced with AMD's X86 architecture processor, which is completely incompatible with PS3 games, which makes those PS3 gamers who like "GTA5" have to keep the original PS3 nostalgic from time to time, and buy a PS4 to play the latest games.

"I like to think from the player's point of view, plus we have unique conditions, no one fights with us for the console, so a new console takes 5 years to update, I don't think there is a problem at all. Coupled with backward compatibility, I believe that with each new version of the console, more and more fresh blood will be attracted to replenish it, so as to ensure that our TV game consoles can continue to thrive, rather than causing players to resent it. Yang Yun said.

Zhao Yongping said: "The market shows that a considerable number of DC players are die-hard fans, and they have gone all the way from DC1 to DC2 to the Kungfu version, and the churn rate is not high, which shows that players are loyal and recognize us." ”

"There are billions of people around the world who have grown up with Dragon Games since childhood, and the number of new customers every year is enough to make up for the passage of old players, and a variety of new games are launched every year, which can allow players to often maintain the habit of playing in the living room, Mr. Yang's plan I thought it was feasible eight years ago, and then I saw the failures of Sony and Microsoft one by one, but it strengthened my confidence!" Zhang Guoqiang sighed: "People-oriented, customer first, I keep this sentence in my heart every day, and always urge us to have hundreds of game project teams!" ”

Yang Yun suddenly stood up and bowed to everyone: "Thank you for being so attentive, Longteng's success is inseparable from the efforts of all of you!" ”

"Don't say that, Mr. Yang, this is what we should do!"

"If you lead by example, of course we will be strict with ourselves!" (To be continued......)
