German publication Igor’s Lab has launched an investigation into why Nvidia chose 19 Gbps GDDR6X memory for the GeForce RTX 3080 and not the faster 21 Gbps variant. There are various claims, but it’s not entirely clear how exactly some of the testing was conducted, or where the peak temperature came from.

The GeForce RTX 3080, which is the newly anointed king of gaming graphics cards, comes equipped with 10GB of GDDR6X memory. Unsurprisingly, the 10 memory chips are from Micron since the U.S. chipmaker is the only one that produces GDDR6X memory. However, some might find it intriguing that Nvidia opted for the 19 Gbps variants, when Micron currently offers 21 Gbps chips as well. Since Nvidia is Micron’s only GDDR6X customer, stock shouldn’t be a problem.
