Nvidia limited the memory speed of the rtx 2080 super

The RTX 2080 SUPER is already here and we have done an extensive review of it here at ProfesionalReview . One of the peculiarities of this new graphics card was that Nvidia had raised the speed of the GDDR6 memory to 15.5 Gbps, becoming the graphics card with the highest memory clock speed on the market. Still, this GDDR6 memory made by Samsung can still be faster.

RTX 2080 SUPER has a memory speed of 15.5 Gbps

For some reason, Nvidia limited the speed of Samsung's GDDR6 memory to 15.5 Gbps, when the nominal speed of this memory reaches 16 Gbps.

If Nvidia were to run their RTX 2080 SUPER at the nominal clock speed of their GDDR6 memory, the graphics card would offer users more than 512 GB / s of memory performance, equivalent to an increase in memory bandwidth of just over 3%. This begs a question, why didn't Nvidia use its RTX 2080 SUPER at Samsung's nominal memory speed?

According to Nvidia, the RTX SUPER series graphics cards were designed to be as easy to manufacture as possible, using the same silicon as existing RTX series graphics cards, along with similar cooler designs and identical PCB designs. Basically an update of what was already on the market.

Nvidia's original RTX series graphics cards offered GDDR6 memory with maximum speeds of 14Gbps. Nvidia's PCB designs are rated for this level of performance, and full 16Gbps memory speeds would require a redesign of the PCB. The redesign of the PCB by Nvidia and AIB partners would have meant an extra manufacturing cost, and that was not the plan. Either way, end users should be able to OC the memory to achieve this speed stably.
