At the end of November last year, innosilicon officially released its domestic graphics card GPU "Fenghua 1", which is oriented to the desktop and server markets. It is known as China's first desktop graphics card GPU supporting 4K high-performance Xinchuang and China's first server level graphics card GPU.
In the product specification introduction, core technology said that it adopted the world's leading gddr6 / gddr6x combo self-developed technology, especially gddr6x. Core technology is the only technology in the world except NVIDIA, and the joint research and development with micron was completed in one year, while NVIDIA took two years**
This statement has aroused many doubts, but the description endorsed for core technology can be found on the official website of micron:
Meguiar said that cooperated with core technology to launch the world's first silicon verified commercial gddr6x IP** The PHY physical layer chip of core technology based on gddr6x uses pam4 signaling mechanism, which is not only a graphic solution, but also a subversive bandwidth and signal performance to unlock more application scenarios.
Recently, at the 2022 Zhuhai software and integrated circuit industry annual conference and digital economy innovation and Industry Development Forum, core technology officially released the world's first gddr6x high-speed video memory technology**
According to core technology, the gddr6 / 6x combo IP launched this time can achieve an ultra-high speed rate of 21gbps (commonly known as 21ghz) for a single DQ IO data channel. The bandwidth under 256 bit width exceeds 5TB / s, which is five times the highest bandwidth of DDR4 / lpddr4 with the same bit width. It can directly catch up with HBM, but the cost is much lower**
Furthermore, core technology's gddr6x IP and gddr6 IP can be compatible in one, that is, "combo". Customers have more flexible choices, and has successfully mass produced and shipped in multiple advanced FinFET processes**
Core technology said that this is the most cost-effective high bandwidth storage solution at present, which can effectively promote GPU, NPU, DPU and other high-performance computing and artificial intelligence products to break the memory wall. It can be called a big killer in the field of high-performance computing and graphics.
At present, core technology 21gbps gddr6x technology has supported the mass production of Fenghua 4K high-performance GPU**
PS: the 21ghz gddr6x video memory chip is used on NVIDIA RTX 3090 Ti flagship graphics card. Is it also the contribution of core technology?
