Crazy hot, I wish I was a gamer,...    Boring FPGA here I come.

[m3sSh3aD]

Personally id go with this,

7800s are going be pants. Same as 7700 FPGA is the only way now)

79xx - CGN
78xx - CGN
77xx - CGN
76xx - Turks
75xx - Turks
74xx -Caicos
73xx - cedar

CGN will SUCK for mining

Has this been confirmed ? Is there no die shrink of the current cards like 6970 -> 7870 with VLIW4 or VLIW5 and based on 28nm etc. ?

[m3sSh3aD]

Same Gutted

But i'd put my money on that site over all the force fed b$ sites out there. Thinq_ / Semiaccurate & tech eye seem to have the juicier stuff but is short in order   All other sites seem to be PR to me

[DeathAndTaxes]

28nm now shipping to OEM says AMD (just 7970 & 7950 only)

http://www.tomshardware.com/news/AMD-Tahiti-Southern-Islands-Radeon-Rory-Read,14288.html

Also I doubt the above report.  It is the only one indicacting 7800 & 7700 will be CGN.

Still from a personal perspectives. 
CGN = better for games.
Lack of VLIW in 7800 series = my collection of 5970s just became more valuable for miners.
I still think 7800s won't be CGN but if they are not a huge problem for me.  I am likely running these 5970s until I move into FPGA anyways.

^^ Slow on the uptake gabi

S/A may have the famed charlie but i go with what they say more than any other tech site as they actually do some journalism and not go to the same sources to hash the same B$. But it as got worse of late But tech is boring tbh. Silicon should have gone 5+ years ago. All the billions spent on going down from 40nm to 20 and below could have had graphene in mass production but noooooo, Intel seem to buy/kill any competitors. Face it, Silicons at a brick wall. Compare AMD to Intel when there at the same die shrink, 40nm vs 40nm etc. Intel suck. Ranting aint i.

I'm ok with my setup until FPGA, i'm already invested infact in FPGA with a whopping 288 shares of 3000 lol.

I managed to extract the following from the 11.12 driver:

Cypress: VLIW5
Juniper: VLIW5
Redwood: VLIW5
Cedar: VLIW5
Cayman: VLIW4
Barts: VLIW5
Turks: VLIW5
Caicos: VLIW5
WinterPark: VLIW5
BeaverCreek: VLIW5
Loveland: VLIW5
Tahiti: GCN
Pitcairn: GCN
Capeverde: GCN
Devastator: VLIW4
Scrapper: VLIW4

So I'm inclined to believe recent reports that all of the higher end cards are using GCN.

Nice find although rather gutting. I hope GCN will be good for mining but i got about 1% on that. I was hoping for good 78xx series 6950/6970 will be popular after price drop......

Deathandtaxes - Only death is guaranteed and you willing wager a bet on this. I know my sources boy  5 BTC seasonal bet

[deepceleron]

Interesting that the slide above shows SHA256 performance, it's almost like AMD figured out who was buying all those video cards...

[Transisto]

Curious 5870 vs 6970 vs 7970 compare, clock for clock and watt for watt ?

[m3sSh3aD]

SHA256... bit dumb question but whats that? Raw calculating power? And if so, are there PR people saying its better than a 6970 for mining? Be surprising as the 5870 was already better than the 6970 so it would be a step foreward..... again..... lol

PR slides like that mean diddly squat, but still interesting what PR companies come up with. '3 times durable', 'OC Genie' etc etc. What happened to good old jumpers and fiddling

[P4man]

So what is that chart showing? Utilization or (power?) efficiency?
Either way, doesnt look like a huge improvement for bitcoin. But indeed, nice that they show it.

SHA256... bit dumb question but whats that?

Lol? Weren't you mining at a few GH/s? SHA256 is the hash algorithm used by bitcoin:
http://en.wikipedia.org/wiki/SHA-2

[m3sSh3aD]

p4man and deathandtaxes are my favourite people around here don't you know! Sorry i don't know p4man to your superior knowledge... (SARCASM) I have a life too.

And yes, I'm mining fine at a profit and i've had my bill. Even at a lowly $2 i was still in the + so that pisses on yours and deathandtaxes bombfire with all your technicalities. I've just cashed 200 BTC in for £460 with the crimbo NY rush. I expect it go up to the end of the week and then drop to its 2.5 - 3 $ where it stands. Thats until spring season with holidays when it goes up, and next Halloween time and then November the BTC goes down to 25 BTC per block which will cause a bit of madness but Christmas an NY will be bonkers next year

Stick that in your pipe and eat it and i bet i'm right, I know cause i look at it from an outside view. NOT FOR PROFIT as you 2 do. As i've said a million times, I'm off on vacation for 2 months, blab to you later

Slide Snipped.

Interesting thing is that the chart is PER MM^2.  There is a die shrink thus each transistor is half as large.  With no architectural changes one would expect SHA256 performance to be (roughly) 2x simply due to the die shrink.  Right?  Isn't the chart indicating (once you factor out the die shrink) that the 7970 architecture is worse @ SHA-256 than a 6970?  (i.e. if the 7970 was manufactured @ 40nm instead of 28nm it would be worse or if the 6970 was manufactured @ 28nm it would be better).

Now if only the SHA bar was the AES one.  It shows what a little optimization can do (performance gain is far beyond what die shrink alone would achieve).  It makes sense AMD would optimize AES performance.  AES is more likely used by everyday users than SHA.  Winzip for example announced new version which is OpenCL accelerated to allow strong encryption/decryption of files much faster than CPU based versions.   I would expect other archive utilities (7zip hopefully) to follow suit.

Interesting point on the MM^2, It would make it something like 60% less efficient or something if what you say rings true. This would be on par with Nvidia's cards more or less as predicted.

Time will tell i suppose, Not long now

[m3sSh3aD]

No no, p4man is such a known troll/loser/dumbass here that he will soon just change his account.

Yes, I've had his shit when i was only trying help and advice people on OC'ing and what not. Kept telling me i'm a moron. Well who's the moron making money and going on a 2 month vacation now! He is a loser. Deathand taxes at least comes up with some good suggestions. I got 1 thing wrong (i said 5990 not 5970 but i believe its been rebranded or different AIB's using 5990). So i was right i believe on that as well.

I offer my insight and opinion and am willing be corrected and ask questions, not just jump on someone cause your opinion id different. All my stuff comes FROM REAL WORLD KNOWLEDGE, i wonder about p4man myself..... Get the men in white!

[Mousepotato]

Wait.. so what's the verdict?  Does the 7-series suck for hashing or not?
