(FPS value comparison, MediaTek has become a dog ...)
Why is Qualcomm so awesome? Because somebody else's GPU technology is their own. At the beginning, they bought Adreno technology from AMD to continue development, while other manufacturers wanted to buy the authorization of ARM. That's why Snapdragon's GPU is Adreno XXX, while Samsung and MediaTek's are ARM Mali-XXX. One is your own, and the other needs the authorization of the buyer. Who do you think is your lifeline?
At this time, another problem appeared. It seems that Samsung 8890 and MediaTek X25 both use ARM Mali-T880. Why is the gap so big? The answer is in the suffix of ARM Mali-T880. Samsung 8890 is ARM Mali-T880 MP 12, and MediaTek X25 is ARM Mali-T880 MP4. To put it simply, there are 12 computing cores on the GPU of Samsung 8890, while there are only four on MediaTek X25 ... What's the difference? Mali-T880 chip can actually have 65,438+06 cores, but the number of cores should be considered by the manufacturer. The more chips are taken, the higher the technological requirements will be, and the calorific value will soar. Under the condition of ensuring the balance of performance and heat dissipation, Samsung's technical ability only dares to take 12 cores, while MediaTek's technical ability can't reach, so it can only take 60 out of four. 12 core GPU's 8890 performance barely tied with Xiaolong 820. Go to MediaTek X25, a cool place. By the way, how much is Samsung 8890? How much is MediaTek X25? So don't think about it, you can get it if you pay. This is the eternal truth. In Meizu's words, enough is good. After all, MediaTek has low power consumption and low fever. In fact, it is impossible to save costs and increase one's ability. The same area can't hold so many cores. . . . Generally speaking, Qualcomm ranks first in GPU performance, followed by Samsung (not far from Qualcomm) and MediaTek ranks last. .....
MediaTek always considers these things from the difficulty and cost of production process, because MediaTek doesn't have its own GPU, so it buys GPUs from mali and PowerVR. But adreno in Qualcomm was originally bought from AMD agricultural enterprises, and it also spent a lot of money on research. Imagine that it is self-evident whether a thing is cheap to produce and develop by itself or to buy from others.
Secondly, in order to solve the fever problem in MediaTek, the previous MediaTek technology was relatively backward. Even the processor p 10, which focuses on low power consumption, is still using the 28 nm process. In order to control the endurance and fever, the image processing level has to be castrated.
Secondly, it is cost. Redmi note4 uses MediaTek X20 processor, but the mobile phone only costs 999 yuan, which is definitely lower than the positioning of a flagship chip in Qualcomm. X20' s image level can only reach the level of Qualcomm's flagship adreno330 three years ago.
Finally, let's recall that a few days ago, we wanted to play online games with p20 for two years. Needless to say, the level of T880 MP2 doesn't mean that it won't be stuck for one year or two. Even the T880 MP4 of X25 is ridiculed for its weak performance, which can compete with the image level of Kirin 955 (laughs).
As for cost and cooperation authorization, NVIDIA has the best GPU for mobile phones at present, but it doesn't cooperate with others. The public version architecture is also divided into multiple models, just like what graphics card is installed in your computer, you should also consider the architecture problem. MediaTek itself is facing the domestic low-end market, but it does not mean that its performance is low. On the contrary, MediaTek's small adventure is still in line with the mainstream of the market. Even the best Qualcomm integrated GPU is not as good as Apple's own architecture.
The CPU architectures of mobile processor manufacturers such as Apple, Samsung, Qualcomm, Huawei, MediaTek, and Ziguang Zhanrui all originated from ARM. Under the same architecture, the performance of each manufacturer will not be much different, and the key to the finale is the GPU.
The full name of GPU is graphics processing unit. GPU reduces the dependence of graphics card on CPU, and replaces part of the original CPU work, especially in 3D graphics processing. At present, the PC has gone from the earliest melee to only Intel, NVIDIA and AMD(ATI was acquired by AMD).
Different from the desktop GPU market, the competition pattern of mobile GPU is much more complicated, and there are dozens of manufacturers who can do mobile GPU. At present, the mainstream architectures of mobile GPU market include PowerVR of Imagination, Adreno of Qualcomm, Mali, Vivante, Brodcom, NVIDIA and Intel of ARM. In recent years, more and more mobile phone chip manufacturers have joined the team of independent research and development of GPU, NPU and baseband chips, including Samsung, Apple and Huawei. The importance of GPU is not only reflected in image display, but also closely related to VR/AR and AI devices. For example, GPU can accelerate the AI used in the cloud.
MediaTek wants to improve the performance of GPU, but the strength does not allow it. If the strength does not allow, you have to buy someone else's mature architecture. This can't be said unilaterally that MediaTek can't do it, nor can it be placed in such big factories as Apple, Samsung and Huawei. Since the introduction of the A-series processor, Apple has been using the PowerVR series GPU of Imagetion Company. It was not until April 20 17 that all imaging technologies were abandoned, because the self-developed GPU made a breakthrough. Huawei Kirin has always used ARM's complete GPU authorization scheme Mali, and the early K3 series also adopted ViVante's GPU architecture.
Making chips is not only about money, but also about talents, technology and background. Otherwise, Apple, Samsung, Qualcomm, Huawei, MediaTek and Ziguang Zhanrui will not buy mature CPU architectures directly from ARM, but mature GPU architectures from Imagination, ARM and Vivante.
MediaTek jumped from the label of "king of shanzhai" to "exclusive for thousand yuan mobile phones", and then to "nuclear maniac". Before the popularity of smart phones, MediaTek's one-stop solution won the favor of shanzhai mobile phone manufacturers. At that time, all the shanzhai machines circulating in the market used MediaTek's chips and solutions, and the only difference was the plastic shell. MediaTek, labeled as the "King of the Cottage", counted his money softly.
The wind of shanzhai mobile phones was quickly swept by the frenzy of smart phones, and MediaTek joined the Android camp to enter the smart phone market, but all of them were thousand yuan phones when they left the factory. MT6589T released on 20 13 was first released in Redmi 1 generation.
Sometimes a good card will be smashed to pieces. When MediaTek, who tasted the sweetness from the smart machine, tried to attack from the low end to the high end, Helio X 10 "Real eight nuclear" was beaten to pieces by Red Rice Note3, and was labeled as "Thousand Yuan Machine" from then on.
MediaTek seems to be obsessed with multi-core cores. When he arrived at Helio X20, he brought the number of mobile phone cores to 10 core. However, at that time, the 20nm process could not suppress the Cortex-A72 and Cortex-A53 cores of 10 core, which led to serious fever and frequent frequency locking, that is, "one core is in trouble, and nine cores are watching the wind."
MediaTek has always wanted to turn over a new leaf, but his bad reputation has long been known to the public. If the chip is not sold well, it will affect the income and profit, resulting in insufficient research and development funds. Not to mention the self-developed GPU, it is still to improve GPU performance.
All this changed after the launch of the 20 19 series. The first cat 1000 ranked first in the world, which reversed the bad label of MediaTek by most people in the past. Salted fish that change their minds will turn over. With 7nm technology and Mali-G77 MC9, it can say "MTK, yes" to those who say that MediaTek refuses to improve the GPU.
Don't improve gpu, because most people in China don't know what gpu is for! ! Even if there is, I don't know which is better. The only thing I know is how many cpu cores there are and how much memory there is! ! What is the capacity! ! What a big screen! ! For girls in the workplace, appearance, photography, appearance+photography is enough! ! !
Upgrade gpu… 1, and the power consumption will increase a lot, reaching the level of 820, and the power consumption of gpu will double. 2. memory bandwidth needs to be added. Now mobile Soc*** uses memory, but memory bandwidth is not enough. No matter how powerful the gpu is, it is necessary to increase the memory bandwidth, either by increasing the bit width channel or increasing the frequency. Therefore, we should use more advanced technology to increase the core area. 3. Heat dissipation, memory and GPU transistors increase, total heat generation increases, frequency increases, and total heat generation increases. The process remains unchanged, and basically the heat dissipation pressure is high. Both CPU and gpu have been down for a long time, and the performance may not be as good as the poor gpu.
Finally, to put it bluntly, it is cost limitation and insufficient research and development strength.
MediaTek is different from Samsung Qualcomm. Its processors are all common CPU and GPU. Although the performance of public CPU and GPU is not weak, it is still a little less than the independent architecture of Samsung Qualcomm. The advantage of Qualcomm is that it has Adreno GPU bought out by AMD, and its performance is quite strong; Samsung's advantage lies in its own mobile phone brand, which reduces the unit price of processor research and development through a large number of shipments. MediaTek does not have these two advantages. Due to the gap between cost and technology, in order to survive, the cost can only be reduced, so the GPU is weak, and I hope it can be improved in the future. After all, brands in China should not give up treatment.
It's not that I can't, but that I can't. There is a saying: I can't do it ~
Even if it is not the cost, it is very difficult! First of all, you have to find another way, otherwise the patent can't be bypassed. Gpu can't continue to put on a facade by simple core. It must have a good architecture and algorithm unit. The most crucial point is that there must be industrial chain support. Otherwise, even if a slightly better chip is made, there is no software to follow up and optimize, and the embarrassment of one core and nine cores is even more magnified ~
It's not that MediaTek doesn't want to upgrade the GPU in MediaTek, but that he can't.
Cost limitation
MediaTek's biggest advantage over Qualcomm's chips is its low price, which limits the high cost of its chips. Don't think that the number of each core in the chip can be increased according to your own needs. As the core increases, the cost will also rise.
Technical limitation
In recent years, the number of nuclear reactors may be what the UNDC can remember. There are too many CPU cores piled up in MediaTek in recent years. Just like GPU, the core can only use ARM. Due to the limitation of chip area, the number and performance of GPU cores will be affected.
Of course, many people don't forget to brag about Qualcomm, his own GPU, his own GPU core and so on when discussing mobile phone chips. In fact, every chip manufacturer has its own defects and advantages. Qualcomm is really good at making mobile phone chips, which is also based on his years of accumulation. The so-called GPU is also obtained through purchase. If other chip manufacturers have such conditions, they can achieve this effect, or even better.
