The Fermi Thread - Part 3

[Olivon]

No chip is designed to operate at 100C+.
You're physically killing the silicon in this case. There is no way around that.

Believe me or not but that the truth and W1zzard is not a noob too ;p

HD 4870 was really hot too especially with VRM's. Just have a look :

Back to the subject, it seems that Fermi 1st generation isn't a great deal.

Hope ATI prices go down though, I don't want to pay a HD 5850 @ 250€, more 150-200€. Competition FTW

does anyone know what this connector is for?

nVidia greenlight logo if I remember well

Yeap , my HD4850 went up to 110C Shader and 116C MemIO while running OCCT stress test for few minutes and still running till today with no problem at all

Is that is part of the Metal heatsink showing on the surface , if so then adding a 120mm will get some nice temps and no need to run the stock fan at high speed

120mm fan in this case won't do anything. You have that big cheese grill blocking the whole fin array, and then the centrifugal fan will be next to useless. The whole heatsinks setup is designed to take advantage of airflow along the card's axis.

And this... GTX 480 sample with 512 SPs and possible 600Mhz (1200Mhz).

This looks about right, I guess... Not impressive, but decent enough.

No potential at all. I only see an inefficient premature design intended to be a scalable cloud server product, disguised into desktop GeForce Fermi.

Inefficient, yes. But it has potential. There could be quite a few interesting desktop applications, heavy tessellation environments being one of them.

GTX480 has 3 billion transistors doing what? 2.812 billion are enabled and supposedly working.
Though the originally designed capabilities are disabled on GeForce Fermi.

* NVIDIA OptiX engine for real-time ray tracing
* NVIDIA SceniX engine for managing 3D data and scenes
* NVIDIA CompleX engine for scaling performance across multiple GPUs
* NVIDIA PhysX 64-bit engine for real-time, hyper-realistic physical and environmental effects

What's left? The power consumption.

There is no real-time ray tracing.
The other stuff you mentioned is pure marketing...

I never said he was a noob.
And do not confuse VRMs with GPU chips.
VRM has a different structure and can operate at higher temperatures. Most GPU VRMs are rated for 120C. But the GPU chips are definitely not.
