NVIDIA SIGGRAPH 2018 Keynote Live Website (4pm Pacific)


07:00PM EDT – Kicking off momentarily will be NVIDIA's 2018 SIGGRPAH keynote

07:00PM EDT – This is a bit of an unusual event for NVIDIA, as while they present at SIGGRAPH every year, it's normally a lower-key affair

07:01PM EDT – Instead, this year the man himself, NVIDIA CEO Jensen "the more you buy, the more you save" Huang is giving a full keynote address at the show

07:03PM EDT – This keynote is scheduled to last for roughly 2 hours, which means we're expecting a fairly prolific presentation

07:04PM EDT – Meanwhile if you'd like to watch the keynote yourself, NVIDIA is streaming it over on their Ustream channel: http://www.ustream.tv/nvidia

07:04PM EDT – Which is also how we're covering this, as AnandTech is not present at SIGGRAPH this year

07:04PM EDT – And of course, the stream, already struggling, has just died

07:05PM EDT – We're back. And here we go

07:06PM EDT – Starting with a traditional video roll

07:08PM EDT – This is basically a historical recap video, showing major graphics moments since the beginning of computer graphics

07:10PM EDT – (The stream is once again acting up)

07:10PM EDT – This is the 30th anniversary of Pixar's Renderman software

07:13PM EDT – Jensen is talking about the various Pixar rendering innovations over the years

07:14PM EDT – "4000 times more computation later"

07:15PM EDT – Artists will use as much computing resources as they are provided. The real limitation is how long they're willing to wait

07:17PM EDT – Now recapping NVIDIA's own GPU history. Riva TNT, GeForce 1, GeForce 3, etc

07:17PM EDT – Jensen is on another one of his Moore's Law spiels

07:18PM EDT – GPU performance has been growing faster than Moore's Law. And Jensen wants to keep it that way

07:19PM EDT – Now talking about photorealistic real-time rendering, physics simulations, and other tasks that need cutting-edge GPU performance

07:21PM EDT – Recounting all of the various graphical hacks used over the eras to reduce graphics rendering to something that contemporary processors can handle

07:21PM EDT – This leading into Jensen's other spiel as of late, ray tracing and how it's the holy grail of computer graphics

07:23PM EDT – Ray tracing is incredibly computationally expensive. Pretty. But expensive

07:24PM EDT – Now recapping NVIDIA's RTX ray tracing technology, which was first introduced at GDC 2018

07:25PM EDT – Rolling the Star Wars RTX demo

07:26PM EDT – 5 rays per pixel in that demo

07:27PM EDT – Suprise #1: What NV just demoed was running on just 1 card

07:27PM EDT – World's first ray tracing GPU

07:28PM EDT – Jensen is harassing the cameraman with the reflections off of the card

07:29PM EDT – The text on the card reads "Quadro RTX"

07:29PM EDT – "Up to 10 GigaRays per second"

07:30PM EDT – "New computer architecture"

07:30PM EDT – "Up to 16 TFLOPs"

07:31PM EDT – (Jensen is still messing with the cameraman. He seems to be genuinely enjoying it)

07:31PM EDT – Comes with NVLink

07:31PM EDT – 100GB/sec

07:32PM EDT – "500 trillion tensor ops per second"

07:32PM EDT – Brand new processor called the "RT Core"

07:33PM EDT – "Greatest leap since 2006", which was the launch of the G80 GPU (8800 GTX)

07:34PM EDT – "Motion adaptive shading"

07:34PM EDT – Architecture is confirmed. Say hello to Turing

07:36PM EDT – Jensen is now talking a bit more about the RT core

07:36PM EDT – It accelerates ray-triangle intersection and processing the Bounding Volume Hierarchy (BVH)

07:37PM EDT – Also talking about the various precision modes, from FP32 down to INT4

07:37PM EDT – Supports 8K displays

07:37PM EDT – 8K video encoding on the NVENC block as well

07:38PM EDT – 754mm2 GPU, 18.6B transistors

07:38PM EDT – 14Gbps memory clock

07:39PM EDT – This is a big chip. Not quite GV100 Volta big, but still very big by any kind of GPU standard

07:40PM EDT – Now diving into hybrid rendering, and the value of the tensor core

07:40PM EDT – NVIDIA will also be open sourcing their Material Description Language (MDL), which they've been releasing for the past couple of years

07:41PM EDT – NVIDIA will also be supporting Pixar's Universal Scene Description (USD) language

07:41PM EDT – (Was that someone mooing?)

07:43PM EDT – Now moving on to demos, starting with comparing different rendering types (rasterization, ray tracing, etc)

07:46PM EDT – Given the extreme die size, I'm going to be a bit surprised if we see this specific Turing GPU in consumer products

07:46PM EDT – Though anything is possible

07:50PM EDT – Compute is being used here to denoise the ray tracing output

07:52PM EDT – Now running another video clip. Everything here is being done in real time

07:55PM EDT – NVIDIA wants a bigger piece of the pie in the visual effects industry

07:58PM EDT – "Large render farms". Now imagine if they were full of Quadros instead of Xeons…

07:58PM EDT – Rolling another video, this time from Porsche

08:00PM EDT – It was also rendered in real-time

08:02PM EDT – (This is a surprisingly laid-back presentation for a Jensen Huang keynote. He's largely content gawking at graphics)

08:06PM EDT – A 6x speed-up in graphics over Pascal

08:07PM EDT – Using AI to get away with lower resolution rendering and then essentially upsample/anti-alias to get more quality

08:07PM EDT – Now discussing Deep Learning Anti-Aliasing

08:09PM EDT – As a result, the combination of ray tracing, faster shading, and DLAA, NVIDIA gets the 6x speed improvement

08:11PM EDT – Now demonstrating real-time scene editing with ray tracing, using RTX

08:13PM EDT – Using RTX for architectural engineering and design

08:15PM EDT – Now demonstratign film-quality rendering. It's moving at a couple of frames per second, which is incredibly fast for a single machine

08:16PM EDT – Now announcing the NVIDIA RTX Server

08:17PM EDT – 8 Quadro RTX 8000s in a single box

08:17PM EDT – General availability in Q1'2019

08:18PM EDT – $125,000

08:18PM EDT – 3250W power consumption

08:20PM EDT – NVIDIA has been working hard behind the scenes to get software and tool developers to adopt RTX, and it looks like they've had a fair bit of success

08:21PM EDT – Quadro RTX 5000: $2300

08:21PM EDT – RTX 6000: $6300. 24GB VRAM. 10 GigaRays/second

08:22PM EDT – RTX 8000: $10000. 48GB VRAM. 10 GigaRays/second

08:22PM EDT – "It's a steal"

08:22PM EDT – And there it is "the more you buy, the more you save"

08:24PM EDT – Now recapping the keynote thus far

08:24PM EDT – Turing and RTX. The most important NVIDIA GPU since G80/Tesla

08:24PM EDT – One more surprise

08:25PM EDT – NVIDIA Reveals Next-Gen Turing GPU Architecture: NVIDIA Doubles-Down on Ray Tracing, GDDR6, & More – https://www.anandtech.com/show/13214/nvidia-reveals-next-gen-turing-gpu-architecture

08:26PM EDT – (I'm getting the distinct impression that something was cut from this keynote at the last moment)

08:26PM EDT – Jensen is now thanking everyone, including the audience

08:29PM EDT – And that's a wrap. Be sure to check out our complete Turing article
