NVIDIA GeForce RTX 5090 Features 16+6+7 Phase Power Delivery on 14-Layer PCB
Fresh details have surfaced about NVIDIA's upcoming flagship "Blackwell" graphics card, the GeForce RTX 5090, suggesting power delivery and board design changes compared to its predecessors. According to Benchlife, the new Blackwell-based GPU will feature a new 16+6+7 power stage design, departing from the RTX 4090's 20+3 phase configuration. The report confirms earlier speculation about the card's power requirements, indicating a TGP of 600 watts. This specification refers to the complete power allocation for the graphics subsystem, though the actual TDP of the GB202 chip might be lower. The RTX 5090 will ship with 32 GB of next-generation GDDR7 memory and utilize a 14-layer PCB, possibly due to the increased complexity of GDDR7 memory modules and power delivery. Usually, GPUs max out at 12 layers for high-end overclocking designs.
The upcoming GPU will fully embrace modern connectivity standards, featuring PCI Express 5.0 x16 interface compatibility and implementing a 12V-2×6 power connector design. We spotted an early PNY RTX 5090 model with 40 capacitors but an unclear power delivery setup. With additional power phases and more PCB layers, NVIDIA is pushing the power delivery and signal integrity boundaries for its next-generation flagship. While these specifications paint a picture of a powerful gaming and professional graphics solution, questions remain about the broader RTX 50 series lineup. The implementation of the 12V-2×6 connector across different models, particularly those below 200 W, remains unclear, so we have to wait for the CES-rumored launch.

Even the guys from r/fuckTAA begrudgingly advise to use the DLSS circus method. I'd say if you have the power it's one of the only ways to get proper IQ in the current TAA landscape so Nvidia is pretty much mandatory if you hate TAA's downsides.
I'd say Nvidia and ASUS is doing it right. I might balk at the 5090 price but I won't doubt it's capability or durablity.
That's experience with R9 5950X & 3090(air cooled)(4 years old) and 7950X w/ the 4090.
Tensor FMA can accumulate to FP16 or FP32. If you’re doing FP16 or lower precision math you really want to be running on the tensor cores because they are blazingly faster.
Full details are in appendix A
Personally I hate TAA in almost every game it's in. It's ok at 4k but below that is shite. Maybe a side effect of me gaming at 4k so long is that at 1440p/1080p it's easier for me to notice how bad it is....
I'll watch the videos, but I'm on my phone right now.
As for the new connector, my only complaint is that my PSU doesn't come with one and I'm not the biggest fan of converters. I could swallow it on a high-end GPU (because it looks better than a million 8-pins), but with a 200-250 W GPU, I don't see the point.
My PSU doesn't have one either, but doesn't need to. It's the side that goes to the GPU that needs to be a 12vhpwr. So all you need to do is just buy a cable, just like I did. No converters required, a cable goes straight from your PSU to the card.
Edit: I've had this conversation a million times over, and someone always tried to convince me with the "universal consensus". It gets tiring fast, so please don't bother.
Yes, if you have infinite money you can throw it away on one for gaming, but the game developers are still targeting far more modest hardware and 5090 owners aren't something they're even paying any attention to.
