Domestic GPU chips are catching up with GTX 1080

In addition to CPUs, domestic companies are also beginning to catch up with international standards in the GPU field. A few days ago, Changsha Jingjiawei revealed that the new generation of GPU chips developed by the company is currently in the back-end design, and subsequent progress will be disclosed in regular reports.



Although Jing Jiawei did not disclose what the so-called next-generation GPU is, according to the company's previous information, the next-generation GPU chip should be the JM9 series, which has been developed since 2018.

On the GPU, Jingjiawei currently has two series, JM5 and JM7, of which JM5400 series has been applied in domestic military aircraft, replacing AMD/ATI products, and JM7200 series adopts 28nm process, performance is similar to NVIDIA's GT640 graphics card , But the overall power consumption is less than 10W, which is much lower than the latter's 50WTDP, and some orders have been obtained.


The next-generation GPU is the JM9 series. This prospect Jiawei mentioned in the report that the JM9 series GPU will be replaced with a unified rendering architecture and increase the number of programmable computing modules, which is in line with the main trends of current graphics cards.

According to the official specifications, the performance of JM9231 can reach the level of low-end products in 2016, and the core frequency of JM9271 is not lower than 1.8GHz, supports PCIe4.0x16, with 16GB HBM memory, bandwidth 512GB/s, floating point performance up to 8TFLOPS, The performance is not lower than the level of GTX1080 and can reach the level of high-end graphics cards at the end of 2017.


Jingjiawei was established in April 2006 with a registered capital of 301 million

AMD's GPU technology enters the mobile phone chip market for the first time

In addition to the release of the Exynos2100 processor, Samsung also confirmed a major event at this Exynos event, that is, the custom GPU that they have worked with AMD for many years will soon appear and will be used on the next flagship machine. The current Exynos2100 processor uses ARM’s Mali-G78GPU core with a total of 14 cores, so the GPU architecture developed by Samsung will be the next Exynos processor, and the GPU will be the focus. This is probably the meaning of Exynos2100’s GPU stacking. The key reason. Dr. InyupKang, president of Samsung’s LSI business, confirmed that the next-generation mobile GPU in cooperation with AMD will be used in the next flagship product, but he did not specify which product. Samsung is not talking about the next-generation flagship but the next one, so it is very likely that a new Exynos processor will be available this year, either for the GalaxyNote21 series or the new generation of folding screen GalaxyZFold3. In 2019, AMD and Samsung reached

Apple and Intel want to join the game, what happened to the GPU market?

Intel recently announced that it will launch Xe-LP GPU at the end of this year, officially entering the independent GPU market, and will hand over to TSMC for foundry. At the 2020 WWDC held not long ago, Apple also revealed that it is possible to abandon AMD's GPU and use a self-developed solution based on the ARM architecture. It will launch a self-developed GPU next year. What happened to the GPU market? Why are the giants entering the game?    Massive data calls for high-performance GPU    Why has the demand for GPUs increased so rapidly in recent years? Because we are entering an era where everything needs to be visualized. Dai Shuyu, a partner of Aiwa (Beijing) Technology Co., Ltd., told a reporter from China Electronics News that visualization requires a large amount of graphics and image computing capabilities, and a large amount of high-performance image processing capabilities are required for both the cloud and the edge.    Aiwa (Beijing) Technology Co., Ltd. is an enterp

SSD vs. HDD: that is nice for You?

Deciding on the proper garage isn’t just about comparing ability and value. The type of garage your pc uses topics for overall performance, inclusive of electricity utilization and reliability. Stable country drives (SSDs) and difficult disk drives (HDDs) are the 2 major storage options to consider and it’s critical to realize the satisfactory use for each and how they compare facet by using aspect. What is an HDD? An HDD is a statistics garage tool that lives within the pc. It has spinning disks inside where statistics is saved magnetically. The HDD has an arm with several "heads" (transducers) that study and write statistics at the disk. It is much like how a turntable file participant works, with an LP record (tough disk) and a needle on an arm (transducers). The arm moves the heads throughout the surface of the disk to get admission to distinct information. HDDs are considered a legacy generation, that means they’ve been round longer than SSDs. In popular, they may be dec
