Nvidia details efforts put into its latest GPU cooling designs

[Corky34]

yawn...the ultimate cooling solution is liquid cooling, the rest is marketing hype. The guyz who will buy a 3090 can simply afford when it comes with a closed loop solution just like Fury x.

Light weight, real (wo)men use LN2.

They rotated the power connector so it lines up with the fins! That's adorable. It looks like a very competent cooling design, so I'm interested to see how it compares to aftermarket coolers. Nvidia are clearly gunning to remove as many other companies profiting between them and the consumer as possible

Interesting that they're selling the new power connector as a packaging benefit and not on the higher power delivery capacity. More amusing that they felt the need to make 2x8pin look as big as possible in comparison by including both sides of the connection:

Those 8 pin connectors are also clipping through a couple of the inductors

Is vertical mounting to make it as fragile as possible?
Hopefully the cooler's shroud will support the connector, but are very good reasons why most laptops do not have the power socket attacked the PCB any more.

Is that really an issue? It's a GPU, 5 connection cycles would be a lot

We seem to have managed well enough with plenty of well-used vertically-stacked IO ports on ATX motherboards for decades now, so I should think a "tall" power socket can be mechanically attached to a PCB just fine.

The reason why laptop power sockets are vulnerable is that the plug is usually a sizeable solid protrusion that can be levered or impacted laterally with quite some force and done so repeatedly over a reasonable lifespan; this concern doesn't apply to connectors situated inside a chassis.

Specifications of the RTX3090,RTX3080 and RTX3070 have been leaked:
https://videocardz.com/newz/nvidia-g...cations-leaked

The specifications of the RTX3080 hint at yields being very poor. Despite being massively cut down,and having 40% of the VRAM,it only has a 30W lower board power. I suspect the RTX3090 has 24GB of VRAM,to justify a much higher price. What is the likelihood that RTX3090 stocks,will be much lower than the RTX3080??

Much as was expected. Can see that the GDDR6X memory is the issue here as the 3070 with non-X GDDR6 has a much lower TDP
I expect there to be very few 3090's about

But look at the RTX3090 against the RTX3080. 40% of the VRAM,smaller memory bus,17% less shaders,and yet only a 30W reduction in board power. So that tells me the GA102 is probably yielding very poorly. Its most likely the RTX3090 is just a rebranded Quadro,with the best dies. It is the same problem with the GA100 which is made on TSMC 7NM,it has well over a 350W TDP,but is significantly cut down,and TSMC 7NM is very mature by now.

I suspect the GA104 is using Samsung 7NM/5NM. If its on TSMC 7NM,something is really up with Ampere as a design.

Oh yeah don't get me it appears poor but there is also a mahoosive difference in power useage going to GDDR6X as well.
Hot, hungry and poor yields - as said by nearly everyone over the last week or so

It matches a leak from last month:

So an RTX3070TI also. So even the RTX3070 isn't the full chip!

The first aftermarket RTX3080TI is leaked:

Its another chunky boi.

RTX3070??

[kalniel]

The board power of the 3080 is.. something else. The 2080 was quite efficient, though people complained at getting a mid-tier chip - they had the performance to do so. Now on a supposedly much more efficient process they're increasing it some 50% or so? Very telling.

It's been a long time since Nvidia gave up the efficiency win. No wonder AMD are waiting with the mid-tier.

As long as it means we get a good bump up in the models under £300,that will do me fine!!

Next year.. maybe. If Nvidia are having to use die from a model up (compared to the 2000 series, more like their normal set) and it's a new process then they're not exactly making cost savings in production so I don't think there's going to be any charity with the 3070/3060 for now. Then early next year I guess AMD will release Navi 22/23 which should be at least the same performance but with more RAM and better efficiency, then Nvidia will respond with a refresh version of the 3070 etc. with twice the ram and hopefully (from Nvidia's perspective) better yield and efficiency.

So yes, next year things should be nicely competing.

Even the RTX3080 uses 3 PCI-E 8 pin power connectors!!



The clockspeed slider goes very high.Apparently there are 20GB RTX3080 models too.

We will see,but if I can run Cyberpunk2077 on what I have now,then I might not bother upgrading for a while longer. From the leaks,I suspect the mainstream AMD models might be coming a bit quicker after the launch than we suspect.

It's AMD, they'll drop the prices on the 5XXX series and call it a mid range just like they did with CPUs (I hope)

That would be an emergency stop gap if they need to get another release out quickly, but they know everyone is waiting for RDNA2 so it's of very limited value.
