Codenames and some othe details of the HD9000 series leaked

[CAT-THE-FIFTH]

AMD states the Hawaii GPU will be 30% smaller than the GK110 and 28NM:

AMD Volcanic Islands Codename GPU Model Refreshed Part
Hawaii R9 290X None -True HD 7970 Successor
Hawaii R9 290 None -True HD 7950 Successor
Tahiti XTL R9 280X HD 7970
Tahiti XT R9 280 HD 7950
Curacao XT R9 270X HD 7870
Curacao Pro R9 270 HD 7850
Bonaire XTX R7 260X HD 7790
Oland XT R7 250 HD 6670
Oland Pro R7 240 HD 6570

Seems to suggest the HD 7850 and HD 7870 replacement cards will be faster than the current HD 7970.

If thats the case the Hawaii based cards might be surprisingly quick.

Seems to suggest the HD 7850 and HD 7870 replacement cards will be faster than the current HD 7950 and HD 7970.

Even though they're below the Tahiti cards on the chart?

The chart seems to suggest the opposite, effectively saying:
New top end cards (79x0 replacement, new architecture)
Old top end cards refresh (79x0 with GCN '1.1', as in current 7790)
Old mid end cards refresh (78x0 with GCN '1.1')
Old low-mid end card (7790)
Old low end cards refresh (66|5x0 replacement with GCN '1.1')

Just refreshing with GCN1.1 isn't going to push pitcairn up to tahiti like performance.

What chart?

The current hd78** segment gets refreshed Tahiti XT cores, ie faster than normal Tahiti XT cores.. Savy?

What chart?

The current hd78** segment gets refreshed Tahiti XT cores, ie faster than normal Tahiti XT cores.. Savy?

The current hd78** segment gets 'new' Curacao cores, ie slower than the Tahiti refresh, but faster than the existing pitcairn cores.. Savy?

Or if you're just wanting to define segments differently, you're welcome to Until we see AMD's marketing slides we won't know.

Look at the list. Curacao is going into what is now the HD7700 range.

Top range

HD 79** replacments.
Hawaii R9 290X None -True HD 7970 Successor
Hawaii R9 290 None -True HD 7950 Successor

Middle range

HD78** replacments.
Tahiti XTL R9 280X HD 7970
Tahiti XT R9 280 HD 7950

Low range

HD77** replacements
Curacao XT R9 270X HD 7870
Curacao Pro R9 270 HD 7850

Tahiti XT R9 280 HD 7950

Low range

HD77** replacements
Curacao XT R9 270X HD 7870
Curacao Pro R9 270 HD 7850

Look at the list yourself - it says clearly curacao is the HD7870/7850 refresh. Look at the probable die sizes, look at the probable TDPs.

Extreme end (=titan, 780)

Hawaii R9 290X None -True HD 7970 Successor
Hawaii R9 290 None -True HD 7950 Successor

High end (=770, 680)
79x0 replacements
Tahiti XTL R9 280X HD 7970
Tahiti XT R9 280 HD 7950

Mid range, lower power (=760, 660ti)
78x0 replacements
Curacao XT R9 270X HD 7870
Curacao Pro R9 270 HD 7850

Mid-Low end, very low power
77x0 replacements
Bonaire XTX R7 260X HD 7790

Low end, very low power
6xxx replacements
Oland XT R7 250 HD 6670
Oland Pro R7 240 HD 6570

The 78x0 are relatively small, lowish power chips. Tahiti chips are much larger and use more power, the refresh won't change that. If the list is correct, AMD are adding a new category above the existing 79xx chips that will compete with nVidia's extreme category chips, something they don't currently have at the moment.

There's only 2 card ranges there, R9 and R7. R9 gets curacao, tahiti and hawaii cores. R7 gets bonaire and oland. R9 replaces both the 7900 and 7800 series, R7 replaces 7700 series and introduces new entry level GCN cards (since there is currently no GCN card lower than a 7750). Effectively hawaii replaces the 7990, and everything else just gets refreshed.

Since Tahiti is clearly placed between curacao and hawaii, we can assume curacao is going to be slower than tahiti, which is going to be slower than hawaii. So there's not going be much movement in actual performance. What might shift is the price, but until AMD announce that we're going beyond speculation and into fantasy...




If you want it in old AMD nomenclature:

R9 Gen 2:
Hawaii = 2990(X) - new top end cards.
Tahiti = 2980(X) - Tahiti refresh
Curacao = 2970(X) - Pitcarin Refresh

R7 Gen2:
Bonaire = 2760X - Bonaire (7790) being directly reused?
Oland = 2750/2740 - Oland is already used in mobile cards: direct reuse?

The Tahiti XT v2 card should be faster than a HD7970 with the all new Hawaii core a full performance tier above, so potentially a very fast card.

The Bonaire core for the new card is named as an XTX part and I'm pretty sure the hd7790 uses Bonaire XT, so again a possible performance increase.

According to this the HD7990 replacement will come at a later date.

We’re not targeting a $999 single GPU solution like our competition because we believe not a lot of people have that $999. We normally address what we call the ultra-enthusiast segment with a dual-GPU offering like the 7990. So this next-generation line is targeting more of the enthusiast market versus the ultra-enthusiast one

Yeah, but that doesn't tell us anything about which card is replacing which. If Hawaii is released at $699, then it's replacing the 7990, not the 7970, which means the other ranges trickle down from there. The Forbes interview doesn't actually say much about pricing except that Hawaii won't be priced as high as $999. There's a big price gap for the range to slot into between that and the 7970, let alone the 7870.

The Bonaire core for the new card is named as an XTX part and I'm pretty sure the hd7790 uses Bonaire XT, so again a possible performance increase.

Oh, I'm sure the new card will be faster than the 7790, but the fact that they're keeping the same codename for the silicon suggests it's not going to get a step-change in performance, just some tweaks.

pity there's no pricing details revealed

I don't really think it matters. The top of the range cards seem set to use Hawaii parts and the next range down seem to get beefed up versions of the Tahiti core. That gives us a rough idea of the performance.

The way it seems to me is,

Hawaii = All New GCN 2.0

Tahiti XTL = Re-vamp + GCN1.1

Tahiti XT = GCN1.1

Curacao XT = All New GCN2.0

Curacao Pro = All New GCN2.0

Bonaire XTX Re-vamp GCN1.1

Oland XT Not sure.

[CAT-THE-FIFTH]

Oland is of the same generation as Bonaire. It launched in OEM HD8670 parts.

[jigger]

Some more info. The Hawaii R9 looks set to be a very decent card.

Hopefully this will be the end of £500 GPU's form Nividia and the GTX780/GTX Titan can fight it out with the HD7950 replacement.

Supposedly,it has a 512 bit memory controller!!

Should offer around 400GB/s so the Tahiti ROPs bottleneck looks to have been well and truly fixed! Plus the use of 512 bit bus on a card that seems to be targeting mass market sales would mean AMD have got 28nm large die yields down to a fine art.

Fingers crossed we are finally back to 50% performance jumps and reduced prices per generation and Nvidia have something waiting in the wings. Although maybe Nvidia aren't fully back on track after dealing with the Fermi issues.
