At this moment, the projection screen behind Gao Nian displayed a comparison chart of performance and energy consumption among the RISC-V open-source instruction set, the ARM instruction set, and the X86 instruction set.
Looking at the energy consumption comparison images and the ultra-high work efficiency comparison images, people showed surprised and incredulous expressions.
Because the energy consumption of the RISC-V open-source instruction set shown above was 5 to 6 times lower than that of the ARM instruction set, which is also a reduced instruction set. This energy consumption was unbelievably low!
Of course, it can have such low energy consumption and such high efficiency because the number of RISC-V open-source instruction sets is less than 50!
Therefore, every computer instruction is a very efficient computer instruction, and every transistor is useful and working.
There will be no situation where a small part of the transistors are working hard, and the vast majority of the other transistors are watching and have nothing to do.
Therefore, the RISC-V open-source instruction set can allow all transistors to work, and the final energy consumption is naturally terribly low, and the efficiency is terribly high.
Of course, there are also costs or shortcomings.
If you don't have many dedicated computer instruction sets, you can only achieve the task function that the instruction set should complete through the software level.
If you want to solve it by relying on the software level, it will cause the processor to need larger L1 cache, L2 cache, L3 cache, and memory to store temporary data.
This is one of the defects of the traditional computer structure, the von Neumann architecture, which naturally requires frequent transfer of data and storage of data.
Therefore, a major defect of the RISC reduced instruction set is that it requires a lot of memory, and memory is often more expensive.
Ultimately, this led to the fact that in 1981, although the RISC reduced instruction set processor with extremely high work efficiency and extremely low energy consumption had already been born.
But there was still no way to completely popularize it, let alone defeat the CISC complex instruction set led by the X86 instruction set, and it was only used on a small scale.
In those days, memory was still relatively expensive, to be honest. The reason why the RISC reduced instruction set has been completely popularized in the past ten years or so.
It is also because flash memory was invented in the past ten years, and there have been huge technological innovations in memory technology, which ultimately reduced the price of memory and caused the price of reduced instruction sets to plummet.
At this time, the power consumption of the RISC-V open-source instruction set is so low and the work efficiency is so high, which naturally means that its demand for memory far exceeds that of the ARM instruction set and the X86 instruction set.
But no matter how high the memory demand is, its work efficiency is high. The cost is nothing more than the high cost ratio of memory, which makes the processor a little more expensive.
Now the price of memory is getting cheaper and cheaper. As time goes by, high memory demand is no longer a huge defect.
What's more, there are also technical research routes for near-memory computing and memory-computing integration in the future.
Overall, the future of the RISC-V open-source instruction set is unprecedentedly broad, and it is the core key of the IoT era and the AI era.
However, the people at the scene could not imagine that far, and even only a few people in the world could imagine such a distant thing.
After all, who would have thought that more than ten years later, with the rapid development of artificial intelligence technology and IoT edge computing needs.
The human demand for the RISC-V reduced instruction set, which has ultra-high work efficiency and never lets a transistor have nothing to do, is so strong?
On the stage, after Gao Nian finished introducing the RISC-V open-source instruction set, the next step was the most critical part.
"Okay, that's all for the RISC-V open-source instruction set. Next is the introduction of the mobile phone processor, which is something closely related to everyone."
Along with Gao Nian's words, the picture on the projection screen behind him suddenly changed, and a performance parameter diagram of the Phoenix ×1 mobile phone processor appeared.
Name: Phoenix X1 mobile phone processor.
Instruction set: RISC-V open-source instruction set, Phoenix multimedia instruction set.
Architecture: First-generation Phoenix dual-core 64-bit architecture.
Manufacturing process: 40-nanometer manufacturing process.
Minimum frequency: 220MHz.
Maximum frequency: GHz.
Graphics display: Phoenix T1 dual-core graphics display chip.
Running memory: 1GB.
Storage space: Standard version 8GB, high version 16GB ·
"Such a high frequency, it actually reaches GHz!"
"It's actually a 40-nanometer manufacturing process, which is 20 nanometers less than the 60 nanometers of the Nokia N9 mobile phone processor.
The performance must be stronger."
"Damn, this is a dual-core processor? Doesn't this mean that China has developed the world's first dual-core mobile phone processor?!"
"I don't know how the performance is. I don't understand just looking at the chip parameters." — ·
The people at the scene and the netizens on the Internet started talking.
Because not many people can know how strong it is just by looking at the hardware parameters above.
After all, people in this era don't really like to compare hardware parameters. The only thing they know is how many cores or the phone's frequency, and even very few people pay attention to the manufacturing process.
"Okay, the parameter display of the mobile phone processor is complete. Next is the real machine test, which everyone likes to see.
Whether the mobile phone processor is powerful or not, just looking at the hardware parameters is ultimately like looking at flowers in the fog. Therefore, whether the mobile phone performance is powerful or not, you will know after a real machine test.
The first thing to be displayed next is the game performance!"
Hearing this, many people who like to play games at the scene and netizens on the Internet suddenly became excited.
I wonder if Geek Technology will launch any fun exclusive games this time?
The twenty games launched by Geek Technology last time were really too classic.
Even after 11 months, the monthly sales of those 20 games still rank in the top 100, which proves the classic nature of those 20 games.
Therefore, many netizens have complained that Geek Technology should stop making mobile phones and honestly develop games. This is the right thing to do.
But unfortunately, in the past 11 months, Geek Technology has not launched any other fun games.
Even if some new games are launched, they are just some reskinned games, and the essence is still that game.
This also made many players sigh endlessly, feeling that Geek Technology should deeply cultivate the game field, why is it so indifferent?
At this time, I wonder if Geek Technology will launch games with higher hardware requirements to match this mobile phone processor this time?
Many people are quite looking forward to it.
"Speaking of which, in the past 11 months, most of the energy of our game developers at Geek Technology has actually been concentrated on three games.
Therefore, in the past 11 months, our Geek Technology has rarely launched brand new games."
Speaking of this, the picture on the projection screen behind Gao Nian suddenly changed, and the name and game promotional picture of "CrossFire" appeared.
"As you can see, this is the first game we are going to launch, the mobile game version of 'CrossFire'!"
"Wow!"
Hearing "CrossFire", the people at the scene suddenly burst into an uproar.
Because the game "CrossFire" is obviously not something that the Geek S1 smartphone or even the Nokia N9 can run.
Because although "CrossFire" has very low requirements for computer hardware performance, the problem is that this is a mobile phone.
Where can the small processor of a mobile phone drive a game like "CrossFire".
But now what did they hear, the Geek S2 smartphone can actually play "CrossFire"?
