Nvidia says the RTX 2080 is designed for overclocking, and the RTX 2070 will offer more performance (for ray-tracing) than Nvidia’s Titan XP card. The RTX 2080 Ti is the flagship, clocked at 1350MHz with 4352 CUDA cores and 11GB of GDDR6 RAM (full specs here), while the regular RTX 2080 will be clocked at 1515MHz with 2944 CUDA cores and 8GB of GDDR6 RAM (full specs here). The RTX 2070, meanwhile, is clocked at 1410MHz, with 2304 CUDA cores and 8GB of GDDR6 RAM. Nvidia is recommending PC gamers have a 650W power supply, as the base RTX 2080 draws up to 215 watts of power.
The main promise of these new cards is ray tracing, which is a rendering technique that results in real-time light reflections and cinematic effects that can make games look a lot more like movies. Ray tracing is something PC gamers have been promised for years, and it has long been considered the “holy grail” of video games. Nvidia is now aiming to bring it in real time to the masses.
