Interesting leak about AMD Pirate Islands family of GPUs

Just found it at WCCF Tech. Have fun!

AMD Pirate Islands : R9 300 Series Roadmap Leak, Flagship Cores Bermuda XTX, Treasure Island XTX and Fiji XTX

 

Damn 7GHz GDDR5 on a 512-bit bus?!?

 

Yay competition

Likely 370X will make itself to the 100W thermal envelope for MXM 3.0B cards, doubt they will release the 384-512 bit cards on MXM.

 

Are we sure we aren't looking at the early rumored specs for 1800XT ?

 

"911, what's your emergency?"

Throw some pizza rolls in that computer case. Ding!

 

^ doubt that would happen. Smaller transistor sizes means more performance for the same thermal envelope. If only they made cards more reliable these days though **cough 580M cough**

 

But you have to remember, AMD thinks 95C is a normal operating temperature.

 

The problem unless the shaders are a lot more efficient pitcairn to 370x is not very interesting.

 

48ROP vs 32ROP can make a big difference though.

 

With a clock reduction? It would all line up for a 30% increase which would quite frankly be pathetic.

 

It would still be better than a fourth rebrand of Pitcairn.
Besides "* Values are not indicative of the final product."

 

Well since the new architecture is announced, MXM will soon follow, so some competition on the high end GPU market for mobile buyers.

I wouldn't say 95C is normal operating temperature, but 90's should be the absolute max a GPU should go up to TBH. My 5870M CF in my M17x R2 did reach upper 80's on full load, I haven't yet fully tested the 6990M in my new (well not that new) P170HM.

 

Me either. 95C is way too hot. That's what AMD said was a normal temperature, not me, lol.

 

When did they say that?

 

R9 290X release.

 

Mother of god 7GHz GDDR5 at 512 bits. That's like what, 448GB/s maximum memory bandwidth? Jesus.

Why do you say 95C is too hot? Does silicon or connections melt or something above those temperatures? I ask because some years ago I've had an ATI HD 4670 hit 120ºC+ (while playing Oblivion and overclocking for a few hours) before I realised it's fan had stopped working and that card still works to this day. What exactly determines high temperatures?

 

There are safety limits in CPU's and GPU's these days, and likely won't go above 95C before it throttles the clocks down. The actual true high temp is dependent on the process and usually when the silicon die can actually get damaged. I think many are like 130-135C, but anything above 90C is really entering the "danger zone".

 

I think the thermal problem usually is not the die that go pew pew, it is the stuff around the die get pew pew'd. Excuse my language~, i just feel like typing that word today.

 

My old HD 6870m could peak at 100c but i did run a hefty overclock on it. Normal temps when gaming was usually around 90c.

 

95c? My 7970 doesn't even get to 80c. The 6990m though that was hot but so was the 580m

This is pretty interesting. We might see HBM with upcoming Pirate Islands

Yup same here... My CPU might hit 85C however GPU never goes to/above 80C....
