Even if the GeForce GTX 1650 is pretty much down in the current pixel food chain and is unlikely to be the focus of ambitious players, the planned switch to GDDR6 is quite interesting. Because there is less reason for marketing. This card is not really under pressure in its segment and to push it closer to a super-superted GTX 1650 would actually make little sense.
It remains to be assumed that one wants to clean up the fragmentation of the memory modules and/or that the GDDR5 modules are either now scarce or generally too expensive. While the performance advantage in memory throughput would be significant at 192 to 128 GB/s, it is also questionable whether the rather weak GPU could really benefit from it. The card could, of course, move a little closer to a GTX 1650 Super, but did the market wait for just such a card?
