Light tracing fundamentally curbs this problem. After the introduction of ray tracing technology, the light in the game can be reflected, and the work of stacking light sources with high repetition in the past was greatly reduced.

022 can be said to be a year when MediaTek is proud. The Dimensity 8100 and the Dimensity 9000 launched by

have performed well in terms of cost-effectiveness and energy consumption control, and their performance release is also back and forth against the flagship of Qualcomm at that time.

This situation continued until mid-year, Qualcomm replaced TSMC technology and pulled out Snapdragon 8+Gen1, and regained its face online on the product .

A year has passed in a blink of an eye, and MediaTek's Dimensity 9000 chip has also ushered in a new iterative product - Dimensity 9200.

Not only did CPU use the freshest architecture of ARM, but the performance of GPU has also greatly improved. It was even reported a few days ago that hit Apple just released A16 this year?

What’s more interesting is that this chip also supports hardware ray tracing.

WTF? ? ? Mobile phone, ray chasing? And it is also hardware-level support?

Let’s briefly review what ray tracing is:

Simply put, it is a technology that helps our game screen become more realistic.

Before Lao Huang's hardware ray tracing came out, the shadow effects we saw in the game were all "fake". The developers manually added light sources through a method called "rasterization" .

But the biggest problem with grating is that it cannot interact with other objects, it will not reflect on the mirror or the floor, nor will it penetrate on the glass.

Then the picture created is definitely different from the world we see. In order to reduce these errors, developers have to add " extra light source " as diligently as a little bee to obtain a relatively ideal picture effect.

The consequence of doing this is undoubtedly that the development cycle of is lengthened by , and the resulting picture effect is not real.

. ray tracing fundamentally curbed this problem. After the introduction of ray tracing technology , the light in the game can reflect in . In the past, those stacking light sources with high repetitions were greatly reduced.

In other words, what this Dimensity 9200 is doing now is to move these functions that can only be experienced on the PC side to the mobile phone.

What kind of magic is this? How is the effect of for An Guangzhi on your mobile phone and how is it achieved?

What is the point of moving it to your mobile phone?

After watching MediaTek's latest press conference, I realized that Fa Ge wanted to introduce ray tracing into the mobile terminal, but it was not just as simple as adding ARM's "hardware" to chips.

Fa Ge never jokes, what he values ​​is the whole world.

/ Mobile phone ray tracing, can the effect be seen?

more is useless. Let’s first look at the actual effect. Fa Ge’s technical accumulation in light catching up is mainly reflected in three aspects:

First, it makes the “ shadow ” in the picture softer. Let’s think about our shadows. In the noon sun, it looks different from the sunset. The former is tough, while the latter is softer and the edges are blurry.

With the support of the ray tracing soft shadow effect, we can better understand the impact of light source changes on shadows, making the picture more layered.

Next is the most intuitive point of ray tracing technology, " ray tracing reflection ".

Whether it is the water surface or the smooth ground, it can present a more three-dimensional and more realistic reflection scene.

Finally, it is " ray tracing refraction ", which sounds like the reflection effect above, but in fact it is more like what we often say in the past " global lighting calculation ".

can reflect different light according to the different materials of the object, allowing more details to be added in the dark environment and prevent the picture from looking shady.

It’s all to say that just looking at these effects, Tony is already looking forward to the scene after ray tracing that he often plays.

Which mobile game should I favor today? ▼

And don’t forget, although our mobile phone screen is small, has high brightness, !

Tony's own monitor may not even be as high as 400nit.

blocks on the phone. ▼

And now the flagship level is basically OLED screens, and the contrast effect naturally is higher than the LCD screen.

brightness and contrast are all important factors that affect the actual display effect of ray tracing. After they rise and fall, it feels that when the mobile ray tracing really falls, the effect may be better than expected?

/ What did Fa Ge do in order to realize it?

So, what is the origin of this hardware " mobile graphics card " that supports ray tracing? It can't be that jumped out of the stone.

In fact, the Mali-710 used by MediaTek last year actually supports software ray tracing , but "software support" is still not very good, so there has been no trouble after a year.

But the hardware support is different. Is there any hardware ray tracing core ? The difference in the effects of the two can be said to be completely overturned.

For example, Lao Huang's RTX series that supports hardware ray tracing compared to GTX series graphics cards that do not support ray tracing. After turning on ray tracing, the performance is twice as bad as possible. . . However, the benchmark performance difference between the two is only about 25%.

This year's Immortalis-G715 equipped with Dimensity 9200 has greatly helped the implementation of mobile hardware ray tracing.

According to ARM, ray tracing on this new GPU Immortalis-G715 uses only 4% of the shader core area, which can increase the effect of ray tracing by 300%.

And it is this 300% improvement that makes Fa Ge focus on "safe landing".

In addition to ray tracing, this time the improvement of GPU is also worth talking about. Let's take a look at the improvement of Dimensity 9200 in GPU hardware:

From the familiar ARM public version of Mary (Mali) , we have replaced the brand new prefix Immortalis-G715. From the perspective of PPT, the performance has been improved by 32%, and the power consumption has been reduced by 41%

At first glance, it seems "unusual" ”

But according to the data from Geek Bay test, the GPU performance of this time Dimensity 9200 is really broken by the A16 next door. . .

, I will take action ▼

can only say thanks to Apple for squeezing toothpaste, which allowed Android to achieve a wave of GPU overtake in its lifetime! The performance of

is indeed a bit beyond Tony's expectations. When A15 was released last year, Apple was still saying

Unexpectedly, in just under four hundred days, the GPU had already touched Apple's butt.

Finally, let’s take you to review the other parts of Dimensity 9200 SoC. Every place is not weak. After all, if the wooden barrel has too big shortcomings, it will not be able to catch up on this basin of water, right?

Entertainment Rabbit Running Score 126w+, at this time last year, no one has broken through 100w ▼

Process, the second generation of TSMC 4nm process is used, which simply means that the power consumption is lower than before and the performance is higher than before.

(if it doesn't turn it over)

In addition, its own game engine has been updated to 6.0, and its energy efficiency will be better. The image ISP is upgraded, WiFi power consumption is reduced, video encoding and decoding technology is improved, and it supports higher flash memory speeds. It also supports WiFi 7 (Ready ) . I won't talk much about these Tonys.

/ Is ray tracing the future of mobile chips?

This chip is so powerful, can the brother turn over and sing with ray chasing and continue to make new breakthroughs in the high-end market?

I feel it is a bit difficult. After all, the high-end market cannot stand firm overnight, it must have the potential. However, Fa Ge’s preparation for mobile ray catching up with is something everyone sees. People often joke that Fa Ge is ARM’s younger brother, and he will use whatever technology is given in the public version.

But this thing is really not something you can do with a slap in your head. As early as December 2020, Brother Fa started to think about this thing and started to tinker with this graphic interface called Vulkan.

officially launched the ray tracing SDK solution based on the Vulkan extension in October 2021, and worked together with other manufacturers in this regard.

It was not until this year that Vulkan 1.3, which supports ray tracing, took the "software ecosystem" of ray tracing.

After the accumulation of these technologies, the Immortalis-G715, which supports ray tracing brought by ARM, is just the last shot.

day, the location, people and people gathered together, and finally moved the effects that could only be seen on PC in the past to our mobile phones.

At this point, the two questions we mentioned at the beginning are answered, so there are only one last question left.

/ Do mobile players really need ray chasing?

In fact, we can find examples from the PC side to compare this problem. When the 20-series graphics card was just equipped with ray chasing, there were very few games that supported, as if only " Battlefield 5" and "Metro: Departure". Everyone questioned + was not optimistic. At one time, they thought that this was a conspiracy by Huang to sell the card.

However, with the continuous release of NVIDIA, the number of games supporting ray tracing is increasing.

And thanks to the popularity of ray tracing, developers in the game industry can no longer use traditional gratings to reduce a lot of repetitive labor. Even some traditional film and television industry personnel will use Unreal 5 to assist in their work.

"Beijing Youth Daily", movies and games: fight with each other with strength ▼

Outside the game, the rules of the game are being changed.

Fa Ge is doing the same now. Although the old man of Moore is still alive, people come out every year to say "Moore (law) is dead"

This also means that in the past, as long as everyone "chip performance" can make it increasingly difficult to pay for the bill - everyone chooses TSMC technology and uses ARM architecture, how much difference can it be?

Therefore, manufacturers are also constantly trying to find new "problem solving" ideas to attract more users.

Two years ago, it was the appearance and mechanical structure of a roll mobile phone, and in recent years, it was the image performance and power consumption control of the roll.

Will it be the turn of Fa Ge bet on the ray chase in the next few years?
