AMD: R9xx Speculation

Well, given the love that both major IHVs have for Furmark, I might agree.

 

226 W is ACP and 243 is TDP.

 

Real numbers are better than pure extrapolation.

With GDDR5, power draw is massively due to I/O... for the old 5Gbps H5GQ1H24AFR :

- 32-bit mode 1560/1630mA max
- 16-bit mode 990/1010mA max

That's about 1200mA just for I/O, so a 2Gb chip would draw about 2000mA, assuming the same process, whereas 2Gb are on a newer process.

I don't know if there's more up-to-date data, but that's different from your "40-watt for 8 more chips"... you probably took the E6E as a baseline, but it's not a regular 5870, assuredly with a sightly different VRM (read something about it supporting higher voltage than the 1GB ref board, perhaps just different OCP levels) and probably even with different GPU binning.

 

Anyone have any (good)ideas about the 6970 die size? What about the GTX580 die size while we're at it?

 

AMD is getting annoyingly good at hiding info now

 

FWIW, the rumours float between 360 and 420 mm^2.

 

So is this the millionth time Fudo is wrong that Cayman is going to be ATI's biggest chip to date?

 

732,871 times to be exact.

ok, j/k

 

R600 is a doozy to beat!

 

SI Q2/Q3 2011

Somebody should start SI speculation thread:

For what it's worth, 28nm Radeons in mid 2011 is pretty much what I was expecting…

 

July 2011 is also what I'm expecting:

Bit of a cross post, but here it is

Apparently Cayman might not make release date.

Turks or Caicos@28nm will replace Juniper in May-June 2011, but i think that for Bart / Cayman successor we will have to wait for Sept 2011. The transistor density increase should be around 2.5x. I think AMD will aim for 1.8-2x Cayman, in 30% less die-size (around 300 mm^2). The biggest problem as usual it's the bandwidth.. can a 256bit/GDDR5@7Gps feed a badass probably 6 Teraflops chip?

 

You really consider Fudzilla trustoworthy anything AMD/ATI related?
They also said that HD6(8/0)00 would be delayed 'till november, then updated it that it might be released on schedule after all, but wouldn't be available (in masses) before november

There's zero chance this is anything other than NV FUD to try to convince impulse buyers to go for a GTX 580 instead of a Cayman-based SKU.

 

Wasn't Fudzilla pro-ATI last time around? Whatever. I always leave it B3D to sort out all the rumors for me...

 

Depends on the editor, Fuad always seems to get bad news stories from nv
