Nvidia has introduced its subsequent technology Turing GPU structure at SIGGRAPH 2018. Nvidia is describing the step as much as Turing as “the greatest leap since the invention of the CUDA GPU”, and that’s all because of a mix of Tensor Cores and RT Cores – devoted computational silicon particularly designed to make real-time ray tracing potential.
The first Turing graphics playing cards would be the Nvidia Quadro RTX 8000, Quadro RTX 6000, and Quadro RTX 5000 – out there in This autumn 2018. The RTX is in reference to Nvidia’s ray tracing platform, RTX, which offers particular ray tracing APIs and SDKs for devs and designers to benefit from Nvidia’s GPUs in these high-stress duties. After as we speak’s announcement, the platform is extra vital than ever.
Ray tracing has been held because the “holy grail” of rendering for years, though has been lengthy out of the grasp of latest GPU expertise. It works by tracing the trail of sunshine and the way it interacts with digital objects, which, in flip, permits for a a lot greater diploma of realism than present rendering strategies and workarounds. This consists of correct shadowing, reflections, refractions, and illumination.
But Nvidia believes it has nailed ray tracing with the Nvidia Turing structure. Its devoted RT Cores pace up ray tracing computation by 25x over the present Pascal technology, and together with AI denoising Tensor Cores, Nvidia’s Turing Quadro RTX 8000 was completely able to operating everything of Epic’s Star Wars ray tracing demo alone. That’s no small feat. When we first noticed this gorgeous demo it was operating on a DGX station value $70,000. Only months later, it runs on a single card – albeit a $10,000 one.
The Turing GPU, named after British mathematician and pc scientist Alan Turing, options an entire new streaming multiprocessor (SM), too. These new core clusters add devoted integer cores and a unified cache structure. The high Turing GPU will characteristic 4,608 CUDA cores, 576 Tensor Cores, and take up 754mm2 on the cardboard – a significantly bigger footprint than Pascal at 471mm2.
Turing may even be fed information by speedy GDDR6 reminiscence – Samsung’s 16Gb GDDR6 chips to be exact. The high Quadro RTX 8000 card comes with 48GB of GDDR6, the Quadro RTX 6000 24GB, and the Quadro RTX 5000 16GB.
These Quadro playing cards additionally verify Nvidia’s dedication to the VirtualLink commonplace. Confirmed final month, VirtualLink is a USB Type-C port designed to ship all the facility and information required for a VR expertise, and Nvidia has been working alongside Valve, Oculus, AMD, and Microsoft to implement the brand new commonplace throughout numerous {hardware} to create an trade commonplace.
But this isn’t affirmation of the Nvidia GTX 1180 / 2080 simply but. The Quadro playing cards, for all their technical developments, additionally include an enormous worth premium: $10,000 for the RTX 8000, $6,300 for the RTX 6000, and $2,300 for the RTX 5000. The significantly cheaper GeForce playing cards gained’t be fairly as kitted out.
But, at the least now we have some concept of what to anticipate on August 20, 2018. That’s the day Nvidia shall be holding its GeForce Gaming Celebration in Cologne, solely moments earlier than Gamescom kicks off. Nvidia is promising “spectacular surprises” on the occasion, which is sort of actually next-gen GeForce graphics playing cards. If it’s simply one other Nvidia PC monitor in any case this, I’ll begin flipping tables.
