AMD: Southern Islands (7*** series) Speculation/ Rumour Thread

hmm that great overclock numbers make me think rumours about nvidia's leaving hotclocked SPs is real.. even a factory overclocked card can do %45 better lol, ppl should reach 1400-1500MHz with msi tf iii, asus 3slots and gbt 3fans cards vs..

also feeding the conspiracy theory i dont know but isn't there a rumour that Tahiti's CU count is factor of 3 ?

 

Interesting. Talk about going beyond the usual canned benchmark review.

So 1.17V looks like a regular operating voltage, not just some overclock configuration. That explains the higher than expected power consumption at load. Maybe it's a bit higher due to power gating to compensate for a small voltage drop across the gating transistor?

Or, mind blown, it is HPL after all? Still a remote option, though. Just look at those clocks...

 

this is what he did..

But maybe there are 40 CU designs...

 

"Da Original" ? I smell shens.

 

36 CU = 1 CU-Array (4 CU) for redundancy ?

 

It's not clear from that exchange if they meant there is redundancy for the CUs or for the ROPs.
I can see there being redundant ROPs, since they are no longer per-channel and are fixed-function blocks organized in compact arrays.

A die shot would give the answer, but none has been shown that I know of.

 

How it will split across two of ACE? Looks like a BS to me

 

32 CUs, not 36, no hidden unit for future use. Got that straight from horse's mouth.

 

Looks like there's a lot of headroom in this process:

and they've gone the route of limiting power consumption for now. AMD may need to squeeze in a few new model names between the 7970 and 7990, the latter of which will presumably be the dual gpu card.

 

I suppose they could always release a 7980 or whatever, but I think they're more likely to just let partners make overclocked 7970s: same basic effect, much less hassle.

 

Give me a 36CU, 1400mhz 7970U for £450-500, and I'd be (finally) happy with this card. 50(ish) GPixel and 200(ish) GTexels are nice round numbers.

 

Usually redundancy has been by extra units within "the big unit", not complete extra unit?

 

I might have to drop my GTX580 for this quickly.

Can't wait to see BF3 benchmarks of the Atomic RX.

 

It's ROPs. Also why there are no half RB configurations of Cayman.

 

AMD HD 7950 won't show up on January 9th

It doesnt make sense but Guru3D corroborates fudo's story and they claim AMD as the source.

Such is the annoyingness of people complaining about "paper launches". Now because of them we dont get the 7950 info for nearly another month, for no good reason. Just so that people wont complain about a "paper launch".

Card would have available early February either way, only difference is now we wont know more about it for longer.

Longtime paper launch supporter here.
