Hello

Also new Tonga XT ???

 

[caswow]

why is mitsubishi mentioned?

 

[ShintaiDK]

So summertime 2015 for AMDs nextgen card seems about right.

Tonga XT is the same as the M295X isnt it.

The article states that Fiji Pro, Fiji XT and Tonga XT are expected January/February 2015. Not sure how you arrived at Summer 2015. It also specifies that the filly unlocked Tonga XT lileky has a 384-bit bus.

When you apply the first sighted by these cargo companies to first product in retail there is usually much longer time in between.

The article besides the cargo list is nothing but speculation.

It took 5 months between GM204 being spotted at Zauba and 980 launch.

Between this, 20nm woes, exceptional GM204 perf/W, news about AMD's hybrid-cooling experimentation and high-end cards 2H slip up,

I'd be more generous when it comes to AMD's Zauba<->launch time interval.

Can you explain more clearly what you are getting at? After the 1st sentence I'm not clear on what you are implying.

 

[ShintaiDK]

It actually took 7 months.

 

[f1sherman]

I am saying that it will take more than 5 months between being spotted at Zauba and Fiji launch.

Ofc I am not *that guy*> I don.t know this. Just my guestimate

So this is what you were talking about.

McConnell and Chung said AMD's next high-end graphics processing unit launch has been delayed until the second half of 2015.

This is the "high-end cards 2H slip up"? Anything to explain the tie in to the rest of your post? Thanks.

Just going to post this here.

4096 ALUs, 800 MHz ~ 1000 MHz
4096-bit HBM1, 1.25 GHz -> 160 * 4 => 640 GB/s(max) (Equivalent to a 1024-bit GDDR5 bus @ 5 GHz)

Volume production 1Q 2014.

Consumer products in Q2 or maybe even Q3.

All I see is printed circuit board assembly parts. Now, these can be made FAAAAAR in advance of the actual GPU being available.

 

[monstercameron]

Gosh this looks beastly going by nostas link. Come on and just tack on 2 excavator modules and call it a day

 

[Keysplayr]

I wonder what the 4096-bit means.

Hbm?

 

[ShintaiDK]

HBM modules dont go to 1.25Ghz. They are currently at 800Mhz and 1Ghz. And the next step is 1.2Ghz.

The performance of the card also lands in the 2x2048SP GCN 1.x area with the same 4096SPs and clocks.

Not to mention the usage of Windows 7 without SP1.

And you can find other odd anonymous results:

Single nVidia card with 3072SPs.

Other messed up results. 38GB DDR5 at 5Ghz?

what are your sources on the bolded statements?

 

[NostaSeronx]

HBM modules dont go to 1.25Ghz.

HBM1 modules go to 1.4 GHz, HBM2 modules go to 2 GHz.

 

[ShintaiDK]

SK Hynix.

800Mhz was Q3. Only 1Ghz in Q4.

[ShintaiDK]

HBM1 modules go to 1.4 GHz, HBM2 modules go to 2 GHz.

Yes in around 2016

 

[NostaSeronx]

Yes in around 2016

Nope, around 2013 actually. AMD has been verified for HBM2 with all designs.

HBM1 stock max is 1.4 GHz, this for Q3 2014 designs and Q4 2014 designs.

The hybrid cooler suggests Fiji is a 28nm part, large >500mm2 die (from the earlier confirmation/leak), very power hungry.

28nm is so mature I doubt there's any issues with launching it sooner than you think.

 

[f1sherman]

AMD will have no problems hitting 250W even on 250mm2 20nm GPU.
GCN needs serious perf/W upgrade.

Q2/Q3, or H2 2015 20nm launch suggests >500mm2 28nm design was ditched.

But yeah, I guess (and hope) that hybrid cooling was made for that 28nm design.

 

[raghu78]

Wow 4096 SP with HBM1. thats massive. I hope AMD has made serious architectural efficiency improvements to improve perf/watt. These chips need to be competitive in perf and perf/watt otherwise AMD would just be shooting itself in the foot. I am waiting to see if AMD has improved perf/shader, perf/watt and perf/sq mm. If they have then its going to be one hell of a card. :biggrin:
