Peddie predicts we could have real time ray tracing on our PCs in less than 6 years
Nvidia demonstrated real-time raytracing at GDC and again at GTC using their DGX station super computer through the DirectX Raytracing (DXR) API. That system provides a theoretical compute capability of over 63 TFLOPS for the total system, of which about 62 TFLOPS were used for the ray tracing. So a threshold or benchmark of sorts has been established for what it will take to get hybrid real-time ray tracing (RT RT) on a consumer desktop machine.
Sixty-Two TeraFLOPS, is a lot of FLOPS, the average PC today with a GTX1080Ti has about 11 TFLOPS (SP32). So, assuming Moore’s law continues, and we get a doubling of performance every three years, when could we expect to have real time ray tracing running games and other things on a PC?
By 2024 or sooner.

However, as cool as it would be to have a game displaying real time ray traced images, it will be the designers and engineers who will be more excited about the prospect.
One of the great things about ray tracing is that you can use it many different ways. You can use a little or use a lot. The demos shown at GDC and GTC showcased a spectrum of examples, there will be more at Siggraph and the innovation is just getting started.
Peddie has done an analysis of what it takes, and some of the developments in ray tracing in this week’s issue of TechWatch.
Tech Watch is the front line of JPR's information gathering service. Our writers find stories of interest to the graphics industry including our core areas of study: graphics hardware and software, workstations, gaming, and design. We add our research, historical context, and insight based on our analysts' deep knowledge of key industries. The result is a powerful base of information, which JPR uses to inform our studies and we offer to clients as a resource for their own research and better market understanding.
Formerly distributed as a bi-weekly PDF, Tech Watch has gone digital and is available to our clients online through their personal dashboard at Jonpeddie.com. Now our content is searchable and readers can save stories for further research.
