Nvidia RTX 2080 Ti and RTX 2080 specifications leaked

When images of Nvidia’s GTX 2080 Ti and GTX 2080 Ti emerged, several educated guesses could be made, especially with regards to memory bis sizes and configuration changes over Nvidia’s previously announced Quadro RTX lineup. 

With the GTX 2080 Ti reportedly shipping with 11GB of GDDR6 memory, we could assume that the graphics card would be using a 352-bit memory bus, a cut-down version of the 384-bit bus that is present in the Quadro RTX 8000/6000. Using the same logic we could also assume that the RTX 2080 is based on the same silicon as Nvidia’s Quadro RTX 5000, which employs a 256-bit memory bus, an ideal size for a GPU with 8GB of GDDR6 memory. 

Now, courtesy of Videocardz, we have detailed specifications for Nvidia’s RTX 2080 Ti and RTX 2080, each of which are somewhat downgraded versions of Nvidia’s Quadro RTX 6000 and 5000 respectively.

These rumoured specifications give the RTX 2080 Ti 256 fewer CUDA cores than Nvidia’s Quadro RTX 6000 and 1GB less VRAM. This disparity provides Nvidia with enough wiggle room to perhaps create a new Turing-based GTX Titan GPU, which has 4,608 CUDA cores and a full 384-bit memory bus with 12GB of GDDR6 memory. 

The RTX 2080 has 128 fewer CUDA cores than Nvidia’s Quadro RTX 5000, which is 384 more than Nvidia’s GTX 1080 graphics card, a 15% boost in CUDA cores over its immediate predecessor. If this is combined with clock speed (or performance per clock) increases, Nvidia could perhaps yield performance improvements that are upwards of 25%, though this remains to be seen.

Nvidia is expected to reveal their Geforce RTX series of graphics cards at their “Be For the Game” Livestream on Monday, August 20th. This live stream will be available to view here.
