Topic: Information on ATI 7xxx Series Dec. 5th! - page 5. (Read 15042 times)

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

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

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.

^^ 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.

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

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. 

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

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. ?

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

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

Dec 5 came and went... No sign of REAL cards.

Just going by the $/MH it's not that great, but it's a 95w card, which is pretty good.  That's about half what a 5870 does.

Has that been confirmed, or is it still speculation?

Poop for mining, good to hear that.

Some speculation on pricing.

Looks like 7850 may be $199 at launch (not as attractive as my guesstimate of $150).  7870 might be $299 which would be worthless for mining.  Honestly I don't see that price holding.  Should have ~20% higher performance for 33% higher cost.  Gamers aren't going to like that.

I think the 7850/7870 pricepoints will slip after the launch day demand dies down.

While it is inferior clock for clock and ALU for ALU the overhead isn't that bad.  6xxx series don't underperform the 5xxx series by much.

The 7xxx series has the huge advantage of a die shrink and that means (slighly less than) double the performance per $ and per watt.  The performance per $ gain isn't that exciting but imagine all 6000 series GPU suddenly using half the power.  That is pretty cool.

However the 79xx are likely going to be poop.  The architecture is really geared towards large complex interactions that simply don't existing in SHA-256.  The wattage (guestimated by looking at connector types) is also worse.  That likely is from the power hungry and ultra fast XDR ram (which is beyond useless for mining).

So I stand by my earlier statement that the 7900 series is going to be poop when it comes to mining.

The 7850 & 7870 "may" be decent miners but given the huge availability of used 5xxx series GPU, the rising performance of FPGA designs, and the fact that mining capacity likely needs to decline not grow makes me think that even the 7850/7870 are simply in the wrong place at the wrong time.


Of course will will.  Moore's law marches on.  7990 has less ALU because they are more complex but it is still ~1600 ALU.  AMD won't stop making more powerful cards.  In say 2 years they will have a next-gen card (8000 series?) and the most poweful dual GPU card will likely be ~3200 ALU.
