107: Feng Fu's discovery

A certain university in the Beijing.

School of Engineering.

Guan Liang excitedly received the latest mi 3 from the Rufengda courier. As a mi fans, he naturally wanted to snatch the first release. He didn't expect Xiaomi to be so efficient this time; the items were shipped out on the same night after he successfully purchased it, and it was delivered to him the next day.

This time, he bought the snapdragon 800 Unicom version of the mi 3, not that he looked down on Nvidia.

It was just that he had previously bought an HTC phone with a Tegra 2 processor. The four thousand yuan phone's heating and lagging almost took his old life, so this time he would rather switch to a Unicom card than buy the Tegra 4 mi 3.

"Old Guan, did your new phone arrive so quickly?" His roommate Feng Fu saw him walk in excitedly with the express box.

"Haha, Lei Jun said this was an in-stock sale. After paying yesterday morning, it was shipped out in the evening. This is the first time it's been so fast; Rufengda was finally efficient for once."

Seeing Guan Liang about to unbox it, several roommates who didn't have classes also gathered around.

"Wow, it's beautiful!"

"Xiaomi has completely changed its design style. This is much cooler than your mi 1s."

"Turn it on quickly and let me see. I'll save up some money and get one too."

Amidst the discussions of his roommates, Guan Liang turned on the phone, logged into his account through the guide, connected to the network, and finally entered the desktop.

"MIUI V5 is really fast. Look at the scrolling and app opening speed."

"Let me try."

"Take a picture and see. Didn't Lei Jun say the camera was also greatly optimized this time? Hurry up and try it."

"Go, go, go, get out of the way. I'll transfer the data first. What's the rush?"

Guan Liang impatiently shooed his roommates aside.

"Oh, so you're pushing your godfather aside just because you got a new phone, huh?"

Feng Fu held his hongmi 1 generation, enviously watching Guan Liang transfer data to his new phone, and casually picked up the nearby packaging box and manual to read them.

It wasn't a big deal, but he did find a problem.

Although Feng Fu didn't have money to buy the mi 3 generation yet, he was already familiar with all its parameters, having drooled over them countless times since its release.

"Old Guan, isn't this right? Didn't Lei Jun say this new phone uses snapdragon 801? Why does the packaging say something different?"

Feng Fu's voice attracted the attention of the others, who turned to look at him.

Guan Liang took the packaging box and manual from his hand and looked at them. After a long time, he didn't find anything wrong.

"Old Feng, what's wrong?"

"It is indeed snapdragon 801,"

"Look here." Feng Fu pointed to the back of the packaging box and tapped the content in the parentheses after Qualcomm snapdragon 801 printed on the box.

"snapdragon 801, 8274AB, that's good. What's the problem?"

Guan Liang was very confused. There was nothing wrong with what was written; it clearly stated Qualcomm snapdragon 801 processor.

"What did Lei Jun say at the press conference? He said the mi 3 used the strongest 8974AB of the Qualcomm snapdragon 800 platform. Now it's 8274AB. Of course, it's different."

"Really? Why don't I remember Lei Jun saying that?"

"You remember nothing. You were watching Teacher Misaki when Lei Jun was holding the press conference, how could you remember?"

"Let's go to the official website to see what it says. I'll bring the computer over."

Feng Fu turned on the computer and found the mi 3 details page. Another roommate also opened the mi 3 press conference video on the computer.

After a detailed comparison, the group finally confirmed that the markings on the new phone were different from what was stated on the official website and at Lei Jun's press conference.

At this moment, Guan Liang still couldn't believe it. He felt that a company like Xiaomi couldn't possibly do such a thing. What if it was a printing error on the phone box?

Or maybe there was no difference between these two models?

One is 8974AB, the other is 8274AB. They sound similar.

"There's no difference between these two models, right? Maybe it's a printing error on the box, and there's no such model as 8274AB at all?"

"Let's search online and see. Don't let Xiaomi give you a downclocked version of the 801."

Feng Fu and Guan Liang searched on the web, but they didn't find anything useful about these two processor models. Instead, they found many people asking what the difference was between 8274AB and 8974AB.

However, none of these questions had been answered yet.

"Forget it, let's leave a message on the Xiaomi forum and wait for Xiaomi's official announcement."

Such scenes occurred across the country in the following days. As more and more questions about the differences between these two processor models appeared online, many people kept @An Old Fish to explain.

"@An Old Fish, come out quickly and explain the difference between these two processor models. I feel like Lei Jun has tricked me."

"Haha, the phone just went on sale and the chip was changed. Xiaomi, you're something else!"

"@Number One in the Phone Circle, did you get the engineering prototype this time? Come out and dismantle it."

"By the way, I searched online, and it seems everyone has 8274AB. There's no difference, right? It's not like some have 8974 and some have 8274, mixed usage like that."

[An Old Fish]: "Thank you all for your attention to Old Fish. Seeing the questions you raised, I immediately went to find information and consult professionals. In fact, to understand the differences between these two models, we must first talk about how the Qualcomm 8X74AB models came about."

"First, snapdragon 8974, 8974AB, and 8274AB all belong to the Qualcomm snapdragon 800 series and are uniformly named Qualcomm snapdragon 801 processor."

"Let's first talk about 8974 and 8974AB. These two processors are different. Lei Jun only briefly mentioned it at the press conference, so I will explain it in detail for everyone."

"The main frequency of MSM8974AB is 2.3GHZ, which is higher than the 2.26GHZ main frequency of MSM8974."

"Both processors use the Adreno 330 display module, but the MSM8974AB's main frequency reaches 550MHz, and its GPU module's performance exceeds that of the MSM8974 by nearly 23%."

"The maximum main frequency of the running memory bus also differs. MSM8974AB supports up to 800MHz, while SM8974 supports up to 800MHz."

"The ISP main frequency has increased from MSM8Hz to MSM8Hz. The ISP in Qualcomm processors is somewhat different from what we usually mean by a camera ISP. The ISP in MSM8974AB is somewhat like a co-processor chip, used for low-power modules that handle camera, video, and audio decoding."
