Rumours have been circulating for a long time that the leaked specifications are now considered secure: Nvidia is giving its current RTX graphics card series a little performance boost on July 2nd, in order not to let AMD's Navi-GPU presentation on July 7th take the butter off its shoulders. The new cards don't get new product numbers, but the nickname "Super". The almost never wrong GPU rumor page videocardz already has all the news summarized in an article and a table.
The fact that the blow is going in the direction of AMD could be seen among other things in the fact that at the start only the Nvidia cards with super update will be available, which will play in a performance league with the upcoming AMD-Navi GPUs. So the RTX 2060 and the RTX 2070.
The computing power of all new "Super" cards shifts slightly upwards. Sometimes more shaders are enabled and sometimes even chipsets of the next higher graphics card are used.
The cheapest card - the RTX 2060 - makes the most interesting leap for video editors, however. The super variant now not only gets the slightly slimmed down chip of the previous RTX 2070 (TU106-4xx). To raise the card to a competitive 8GB, the RTX 2060 Super also gets a 256 bit memory interface and is therefore on the same level as the current RTX 2080, which we have tested here already under Resolve.
With a memory throughput of 448 MB/s, the new RTX 2060 Super should therefore land at least at the level of an AMD Vega 64 or a Nvdida 1080 Ti under Resolve. Only at a much lower price. The additional functions like the GPU video de- and encoders should also operate on the same performance level as the larger RTX cards.
Exact prices have not yet been leaked, but it can be assumed that the RTX 2060 Super will be announced under 400 euros at its launch on 2 July.
