We are facing a graphics card that does not match any known model, so it could be a brand new variant or configuration that has half the VRAM capacity, so this opens up a wide range of possibilities on what he might have hid AMD up your sleeve.
What is this AMD Navi 21 GPU with only 8 GB of memory?
Silicon 7nm Navi 21 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 sized chip, competitive against the faster RTX 30 series products from NVIDIA, and AMD has set 16 GB as the standard amount of memory for all products based on this chip despite its interface. GDDR6 memory which is only 256 bits wide.
Since the graphics based on this slower chip are the Radeon RX 6800 and this one encountered competitive issues with the next inferior model, the Radeon RX 6700 XT, there is a lot of speculation about what this new model of GPU could be.
Currently, the theory that seems the most plausible is that it could be a simple prototype (it should be noted, by the way, that according to the UserBenchmark file this graphic was tested on a desktop platform, so it is not an iGPU nor is it a graphics laptop but a dedicated GPU). The GeForce RTX 3070 SUPER has a fragile performance equation with the similarly priced Radeon RX 6800, and any attempt to bridge the gap between the RX 6700 XT and the RX 6800 would cannibalize the latter … unless of course that is exactly what it is. what AMD is looking for.
If this theory is true, AMD could prepare 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 find ourselves 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 competing models, it could therefore make it feel such a movement.
There is another theory which also predicts that we are facing a prototype, but in this case it is a dedicated GPU for laptops (this 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 to do so should offer a reduced configuration and reduce the VRAM buffer to save GPU power, so it might also make some sense. .
In any case, everything remains to be seen, we are faced with a simple mention in a database which, although curious, we will have no choice but to wait and see what will be the next step of AMD. , but what is clear is that this Navi 21 GPU with 8 GB of memory exists and AMD will have something in mind for it.
