The RTX 3080 Ti can have 10,496 CUDA cores

During the run-up to the launch of “Ampere” and the Geforce RTX 3000 series, the delicious Kopite7kimi has often proved to be right, but now takes to Twitter to contradict itself and previously reported rumors regarding the graphics processor GA102-250, intended for an upcoming graphics card that is expected get the name RTX 3080 Ti. Where earlier the leak pointed to a model that, in terms of specifications, lands between RTX 3080 and 3090, he now believes that the 3080 Ti can instead have 10,496 CUDA cores.

* Speculative information

According to Kopite7kimi, the card in question will thus be equipped with what is closest to an RTX 3090 core, which is paired with 20 GB of GDDR6X memory to meet the competition from the AMD Radeon RX 6000 series and its 16 GB of large text memory. With a 320-bit wide memory bus, and four gigabytes less memory than RTX 3090, a possible RTX 3080 Ti will not be a cheap story, but may help Nvidia position itself better against AMD’s top card RX 6900 XT around the ten thousand kronor mark.

Whether the Geforce RTX 3080 Ti will be a final product or not, the future will show, but judging by the varying rumors, AMD’s product plans, together with difficulties in delivering graphics cards to the market, have given Nvidia a real headache.
