So, someone that disagrees with you then. :p

Let's not make it personal with me and pointing the finger at me all the time. This is dishonest and ugly, and you know it.

Here, is the public response. I am shocked about your lack of general knowledge of cooling. :D

"Just like on other recent AMD cards, the GPU reports a second temperature called "Hot Spot" or "Junction Temperature". While the temperature was at 92°C in the testing above, Hotspot reached 110°C. From what I can tell, the throttle point for Hotspot is set to 115°C in the BIOS.

AMD's Radeon RX 5700 XT lacks the highly popular idle-fan-stop feature, but the idle fan settings are excellent—the card is whisper quiet and pretty much inaudible unless you put your ear right next to it on an open bench.

When gaming, the picture changes completely, though. With 43 dBA, the card is simply noisy. It's slightly quieter than Vega 64, but the levels are pretty much identical to the Vega 56 and Radeon VII. Considering the card is also running fairly hot, I really have to question AMD's choice for their cooling solution."

  • Noisy in gaming
  • Overclocking is complicated
  • Driver bugs
  • High temperatures
  • No support for raytracing acceleration
  • No idle fan stop
  • High multi-monitor power draw
  • CrossFire no longer supported

Stock 5700xt is about 2100rpm.. pretty sure that's not 20% fan.

We are talking about load scenarios. No review in the world is reporting 20% fan stock settings in actual usage.

Example, stock, in-game, 2100 RPM:

Mea culpa. Indeed is it around 40%. Yet still is not that loud the actual fan. The moving air is, is not the high pitched noise from eg the 290X and V64 blower fan at around 40%. Let alone the Noctua Industrial 3000s.
The latter are very very loud even at 40%. And I know it for the fact that had 2 on the Morpheus II on the Vega 64, after the Predator 360 pump died in May.

It's certainly quieter than the Vega 56 blower I used to have, which is a big improvement. People just need to stop putting their computer cases level with their heads, and all of these noise issues will go away. ;)

Load temperatures were around 75°C. Now, they are not below 90°C. This is not an improvement.

"Idle temperatures are excellent even with the fans turning off in idle. Gaming temperatures are better than on RX Vega 64 due to the reduced heat output. I think given the 75°C under load, AMD could have adjusted the fan profile to be quieter, allowing for higher temperatures."

Indeed. I do not get it some time. Is like we are all the time with the head in the case trying to see if the GPU makes a noise. I listen to music and playing games or doing work, and the PC is to the side and under the desk.
And is a TT P3 so any sound from PC is added to the ambient. The cicadas outside are louder with the window open.
And at it's normal operating speed, is not louder than any of my last 3 proper cooler GPUs. MSI GTX1080 Armor, Aorus 1080Ti Xtreme or V64 Nitro+.

Is the cooler inefficient and seems doesn't sit properly on the GPU yes. However even on a better cooler this heat needs to move.

The chip is tiny, is half the size of the RTX 2070/V64/1080Ti/290X more than half the size of the RTX 2080, yet while it burns less power is not that much "less" power. So "we" expect from it to dissipate 180W-200W worth of converted electricity to heat twice as fast as if it was made with 14/16nm process. Something impossible until science comes with a better material than silicon.
Imho AMD & Nvidia should start considering big IHS with indium soldering on all their 7nm and smaller GPUs.

But seems everyone in the "tech world", forgets the First Law of Thermodynamics. Some times I truly believe that the significant majority in here didn't do Physics or Mathematics at school.
Some didn't even do History..... :rolleyes:

If they can't make cool 250W cards or if they don't want to, then design 50W chips with the same performance.
My original X1600 Pro was a 40W card.

Well, I use the information from AMD that RDNA 1.0 | Navi 10 is not full new gen architecture but a hybrid between RDNA and GCN https://wccftech.com/amd-radeon-rx-5000-7nm-navi-gpu-rdna-and-gcn-hybrid-architecture/

WCCFTECH says Navi 20 but if it's full RDNA, why would it be called Navi and not something else? And what else is it and why is it being hidden from the public as a name?


Actually, Polaris 10 | Polaris 20 | Polaris 30 is one and the same thing.
Vega 20 is an optical shrink with minor changes of Vega 10.

So, Navi 20 should be the same Navi 10 with improved clocks.

But we haven't reach full inception yet. We must go deeper...
There is rumored another variant to RDNA that isn't available in 5700 series.

X1600 had 217 million transistors at 150mm^2, not 10.3 BILLION the 5700XT has at 251mm^2. To put in perspective 2080 has 13.6 BILLION at 545mm^2
 
Got my 5700XT Today, Gigabytes version :) - the design in person is stunning.

Now I am waiting on the block from EK :)
