Twitter material and user leak @Komachi_Ensaka spotted a very strange AMD Radeon graphics card based on the Navi 21 GPU which only comes equipped with 8 GB of memory, compared to 16 GB of memory typically installed on Radeon RX 6800/6900 based on Navi 21. The product has been spotted in the UserBenchmark database. Could this be a new competitor for better graphics cards, or maybe an OEM-only card?
The card in question has the Navi 21 Device ID (1002 73BF) and Subsystem ID (1002 0E3A), which correspond to an AMD Radeon RX 6800 GPU. not just from a wrong read or spoofed entry, it is also equipped with only 8GB of GDDR6 memory.
Rumors of AMD’s intention to build a cheaper Radeon RX 6800 SKU with 8GB of memory have been floating around for some time, but AMD has never confirmed them, possibly because the cost of memory is not something that concerns him (and his partners among the manufacturers of graphics cards) the most. There’s also the fact that AMD has pointed out that it delivers significantly more memory than competing parts in Nvidia’s RTX 30 series, and may now be forced to go back to 8GB due to various component shortages.
If AMD is actually testing and / or considering releasing a Navi 21-based graphics card with 8GB of memory, AMD could build it in two ways:
- Use a lightweight version of the Navi 21 GPU with half the memory interfaces enabled and equip the card with four 16 GB GDDR6 memory chips. This would allow the company to use its Navi 21 processors with faulty memory / PHY controllers and / or reduce the cost of the nomenclature (BOM) of its card. The performance of such a product will probably be rather poor at high resolutions and in cases requiring more than 8 GB of memory.
- Use a Navi 21 GPU with all its memory controllers / interfaces enabled, but install 8GB GDDR6 chips. This would reduce the nomenclature of the card, but again reduce its performance in games / scenes where 8GB of memory is required, but the memory bandwidth would remain the same.
AMD could sell either of these cards to OEMs or in certain markets like a Radeon RX 6800 LE or a Radeon RX 6700 LE, depending on the performance level. Based on UserBenchmark’s results, the card in question performs worse than the RX 6800 and better than the RX 6700 XT, making an RX 6800 LE more likely. There is also a $ 100 price difference between these two cards, it’s not that the Suggested Retail Price (SEP) means a lot these days.
As with all these leaks and rumors, sprinkle generously with salt. It can be a prototype, a fake or a future product. Without a sufficient supply, just about any GPU with a reasonable price would be welcomed by gamers. We asked AMD for comment, but in general the response on unannounced cards is “no comment”.
