Nvidia Blackwell Architecture Speculation

Quite separately, I hope we can all agree NVIDIA did a pretty solid flex from their cooling and PCB engineering teams in this go-round. This might be considered a tacit recognition of the overall chip design not wowing the critics, and it also might be a nod to a future where they will need to bleed even more power to keep the performance moving in ever-upwards direction.

Will we see a future where high end gaming PCs have to be connected to 240V outlets like you use for your dryer? A PC with a 5090 and 14900K could already use half the continuous capacity (80%) of a 120V 20A breaker.

I surely hope not. I'm still refusing to upgrade my PSU beyond 650W. Going over 1000W just for gaming purposes is a complete waste of energy, IMO.

TBH you can still run a damn good gaming PC on 650W. Something like a 4070Ti Super and a 7800X3D should be no problem for a good 650W unit.

most countries outside the americas and japan have almost double the voltage

Yes I know that but please don't encourage NVIDIA

I've been wondering, why is it okay to run 50A through 12 pins on the new connector when previously we would've needed 32 pins for that amount of current? Do the cables get hot with that much current?

it says 9.5 amps per pin

The Streamline SDK has been updated to support DLSS 4. This update includes the Ray Reconstruction programming guide.

It says on there that the safety factor drops from 1.9 on the 8pin connector to 1.1 on the new one. So I guess that answers my question.

I believe the failure issues were at the insertion points, I don't think there were any claimed issues with respect to the cable wires themselves? At least with my understanding if the cables themselves over heating were an issue than any household device that ran at 1200w+ would have hotter cables as I believe it's the same 16 AWG (including the cable from you PSU to the outlet).

New NV App and driver is out allowing DLSS4 override

My opinion on this is that Nvidia is somewhat just fullfilling a demand and going where the market has chosen to go.

We joke about the 450w+ single GPUs now but really in the past we did have people buying multi GPU configurations which would have that type of power consumption.

If we look at the overall market 750w and 850w PSUs became commoditized and basically carried no premium, with 1000w PSUs becoming relatively affordable. Mesh cases with something like 4x120mm fans became common place and enthuasists might have cases with 4x140mm configurations and more. Manufacturing and design of GPU heatsinks also became much better and commoditized, an interesting example is Fermi with the GTX 480 which we remember as being "hot" but go take look back at what was considered an advanced AiB heatsink compared to now.

All the above came before the recent trend in single GPU TDPs. If we still had the older paradigm than these case and PSU configurations would essentially all be "overkill." So with that said though unless the rest of the environment changes it also limits how higher you can actually take single GPU power consumption going forward.

There is a new feature called "Smooth Motion" exclusive to Blackwell. It seems to do the same thing as AMD Fluid Motion Frames or Lossless Scaling.

NVIDIA Smooth Motion Now Available​

NVIDIA Smooth Motion is a new driver-based AI model that delivers smoother gameplay by inferring an additional frame between two rendered frames. For games without DLSS Frame Generation, NVIDIA Smooth Motion is a new option for enhancing your experience on GeForce RTX 50 Series GPUs.
To enable NVIDIA Smooth Motion, select a compatible DirectX 11 or DirectX 12 game in Graphics > Program settings. Scroll down the list of options on the right to reach “Driver Settings”, and switch Smooth Motion on.


NVIDIA Smooth Motion can be applied to games running at native resolution, with super resolution technologies, or with other scaling techniques, typically doubling the perceived frame rate.
