We are, by what it seems, before a graphics card that does not correspond to any known model, so it could be a completely new variant or configuration that presents half the VRAM capacity, so this opens a wide range of possibilities about what it could have AMD tucked up your sleeve.
What is this AMD Navi 21 GPU with only 8GB of memory?
Silicon Navi 21 7nm from AMD is the one used for the series Radeon RX 6800 and the flagship graphics of the generation, the Radeon RX 6900 XT. This is a fairly large chip in size, competitive with NVIDIA’s faster RTX 30 series products, and AMD has set 16GB as the standard amount of memory for all products based on this chip despite its GDDR6 memory interface is only 256 bits wide.
Since the graphics based on this slowest chip is the Radeon RX 6800 and this one ran into some competition issues with the next inferior model, the Radeon RX 6700 XT, there is a lot of speculation about what this new GPU model could be.
Currently, the theory that seems more plausible is that it could be a simple prototype (it should be noted, by the way, that according to the UserBenchmark record this graph has been tested on a desktop platform, so it is not an iGPU nor is it a laptop graphics but a dedicated GPU). The GeForce RTX 3070 SUPER has an unstable performance equation with the Radeon RX 6800 being similarly priced, and any attempt to bridge the gap between the RX 6700 XT and the RX 6800 would cannibalize the latter … unless of course that’s exactly what it is. what AMD is looking for.
If this theory is true, AMD could be preparing the withdrawal of its Radeon RX 6800 from the market by launching a more competitive product in exchange, which would overshadow the NVIDIA RTX 3070 SUPER but with a lower price in exchange for having the half the memory than the RX 6800. We would therefore be facing a relatively high-end GPU from AMD (let’s not forget that it uses the Navi 21 chip) at an extraordinarily low price compared to the competition models, so it could have some felt such a movement.
There is another theory that also predicts that we are facing a prototype, but in this case it speaks of a dedicated GPU for laptops (it is not the first time that we have seen a desktop GPU in laptops). The RX 6800M comes with 12GB of GDDR6 memory, so an RX 6900M with Navi 21 if AMD chooses it would have to offer a reduced configuration and reduce the VRAM buffer to save GPU power, so it might as well have Certain sense.
In any case, everything remains to be seen, we are facing a mere mention in a database that, although it is curious, we will have no choice but to wait to see what AMD’s next move is, but what is clear is that this GPU Navi 21 with 8 GB of memory exists and AMD will have something in mind for it.
