AMD Radeon Pro professional graphics card with Big Navi 21 GPU and 16GB video memory leaked

Recently, HXL just shared the live images of the legendary new generation AMD Radeon Pro professional graphics card based on the RDNA 2 architecture/Big Navi GPU.

According to the latest information, the new generation of professional “Ampere” N card and “RDNA 2” A card have joined the backplane, and the PCB is more high-end than before. But this professional-grade A card only covers half of the backplane, which is slightly stingy compared to the entire backplane of the RTX A6000.

Judging from the content of the original post on ChipHell, the publisher seems to be wondering why even a little bit of relevant information cannot be found on the Internet, but it is not difficult to guess that AMD is equipped with Big Navi 21 GPU and 16GB GDDR6 for the new generation of Radeon Pro professional graphics cards. Video memory.

With reference to the product positioning of the previous generation of AMD professional cards, there are currently several derivative versions based on Vega GPUs that focus on high-end market segments. The first generation RDNA GPU based on Navi 10 SKU is mainly for budget and mainstream market segments.

Regarding the radiator, the new generation AMD Radeon Pro has been modified in the design of the wind deflector, and the color scheme has also been changed to a silver/blue scheme. The overall graphics card has a dual-slot height, plus a turbofan, with thick heat pipes and dense aluminum cooling fins underneath.

Although the tipster did not disclose more details, judging from the GLXL A1 AISC annotation information in the class, it should be a specific configuration of Big Navi / Navi 21. Corresponding to the RX 6900 XT (Navi 21 XTX), RX 6800 XT (Navi 21 XT), and RX 6800 (Navi 21 XL) in the game graphics market.

However, the 16GB GDDR6 video memory combination confirms that the card uses Navi 21 GPU and 256-bit video memory width, supplemented by 128MB Infinity Cache cache.

The PCB design is only slightly modified on the basis of the RX 6000 (Big Navi) public version card, and it is equipped with a dual 8-pin power supply interface.

As for whether this engineering sample can compete with Nvidia’s Ampere workstation product line (such as the 48GB RTX A6000, and the legendary 24GB RTX A5000 / 16GB RTX A4000), it remains to be tested.
