Nvidia takes to Gamescom to present the GeForce RTX series-- the first gaming GPUs based on the recently revealed Turing architecture, promising to bring advanced features such as real-time ray tracing to the consumer market.
The event had Nvidia reveal three cards, the RTX 2070, 2080 and 2080 Ti. The company claims the RTX series offer hybrid capability able to deliver "6x more performance" than Pascal, allowing for 4K HDR gaming running at no less than 60 frames per second, even on advanced titles. To do so, the cards carry RT cores able to power real-time ray tracing (a means to accurately render the behaviour of light), an NGX "neural graphics framework" integrating AI in the graphics pieline and Turing shading architecture to boost overall performance.
The cards also include ultra-fast GDDR6 memory with over 600GB/s of bandwidth, the high-speed NVLink interconnect allowing for higher bandwidth (up to 100GB/s) and improved scalability in multi-GPU configurations, and hardware support for USB-C and the VirtualLink VR headset standard. Speaking of VR, RTX cards have technologies to improve on such applications, namely Variable Rate Shading, Multi-View Rendering and VRWorks Audio.
As for the individual RTX cards, the RTX 2080 is the base model, clocked at 151MHz with 2944 CUDA cores and 8GB GDDR6 RM. The RTX 2070 is the stripped-down version, clocked 1410MHz with 2304 CUDA cores and 8GB of GDDR6 RAM. while the RTX 2080 Ti is the flagship, clocked at 1350MHz with 4352 CUDA cores and 11GB of GDDR6 RAM. Nvidia suggests pairing with a 650W power supply, since the RTX 2080 draws up to 215W of power.
The RTX cards ship from September 2018.
