AMD Roadmap? Source - Bitdreams

[Stuka87]

Seems plausible.

EDIT: Didn't see the dates and code names. All wrong.

 

[Rvenger]

Nope. Fake

They just used the 7970/7950 spec and adjusted the ROPs and SP. Should be 4gb with 512bit bus or 6gb with 384bit bus.



EDIT: Transistor count seems legit. I think it will be released with more than 3gb vram. But it could release in 3-6gb options I guess.

 

[blackened23]

Release date 9970 : Q4 2012

SOUNDS LEGIT GUYS

Since the 9970 has been out for 8 months now, I figure the 9990 is due any day now. Q2 2013! Oh wait.

Bullshit.

1. The name is not right. The new cards will come out with R9-2xxx naming scheme. Radeon R9-280X for example.

2. The codename is Hawaii.

3. The SP : DP ratio is 2:1

4. The theoretical peak SP performance is mostly right.

 

[3DVagabond]

Not enough of a difference between the 9970 and 9950

 

[boxleitnerb]

Fake, full of mistakes. The OP should have researched better instead of posting this.

Research...........what, exactly?

 

[taq8ojh]

Can't we just wait two (or what) bloody weeks instead of posting nonsense stuff from who knows what stoned source, or speculating about card X having Y or Y+457 transistors?

 

[Keysplayr]

You can also opt to chill. What's the harm? I certainly didn't post this as a fact. Just floating out there recently and shared.

 

[taq8ojh]

There's no harm at all. I am not jumping at you either. I am just saying my thoughts on the whole speculations thing aloud

yeah from what sushiwarrior said Hawaii is a massive chip with lots of sp and clocked low for very good perf/watt . He said Hawaii beats even Pitcairn on perf/watt. So this chip has got to be clocked closer to 900 Mhz. so here are a few combinations which could lead to same theoretical SP performance.

3072 sp x 2 x 875 Mhz = 5376000 MFLOPS = 5.376 TFLOPS
2880 sp x 2 x 925 Mhz = 5328000 MFLOPS = 5.328 TFLOPS
2816 sp x 2 x 950 mhz = 5350400 MFLOPS = 5.350 TFLOPS
2688 sp x 2 x 1000 Mhz = 5376000 MFLOPS = 5.376 TFLOPS

Out of these I am hoping its 3072 sp. That would be really nice. also the memory bus seems to be 512 bit. everybody was expecting a 384 bit memory bus. Since AMD's ROPs have a crossbar to the memory controllers I think they don't need to match the memory controllers perfectly in ratio. Tahiti had 4 ROP partitions of 8 ROPs each tied through a crossbar to six 64 bit memory controllers. Hawaii looks like it will have 48 ROPs with 6 ROP partitions of 8 ROPs each tied to 8 64-bit memory controllers.

know what you're saying. These forums are mostly speculation threads anyway.

So what was/is Curacao supposed to be?

 

[NostaSeronx]

Volcanic Islands =

OP : QP : DP : SP

1 : 2 : 4 : 8

VI is competitive with Knight's Landing through HSAIL.

 

[zlatan]

So what was/is Curacao supposed to be?

The original successor of the Tahiti GPU. Hawaii is the successor of the canned Curacao.

 

[el etro]

This probably could have been the canned Sea Islands GPUs(Refreshed GCN like Bonaire is - 8000 original series). Their mid-low end part is a downclocked Bonaire....

 

[tviceman]

I think there are some mistakes in the graphs and some things that aren't concrete yet (like core clocks) but the transistor, TDP, and processor count seems very, very plausible to me. 25% more GCN cores and 800 million more transistors sounds like the kind of same-node bump within AMD's scope of R&D and resources available to them. I think this graph is based on the actual hard specs of the chips, so yes I think it's real.

 

[Rvenger]

It was a good find Keys but I think some info has been copied over from Southern Islands. I think the transistor count will be somewhat correct though. Bigger but not quite a big die.

 

[sushiwarrior]

yeah from what sushiwarrior said Hawaii is a massive chip with lots of sp and clocked low for very good perf/watt . He said Hawaii beats even Pitcairn on perf/watt.

Uhhhh don't think I'd go that far, just significantly better than Tahiti that's for sure.

They just used the 7970/7950 spec and adjusted the ROPs and SP. Should be 4gb with 512bit bus or 6gb with 384bit bus.

We are all hoping for that AND with a lower price then a 384 Bit GTX 780 with 3 GB's of vRam.

Man the Old 65nm GTX 280 512Bit/1024MB at 800Mhz can power a 2560/1440 PLS (IPS) display for watching movies staying under 60C without issues but gaming is another matter.

1500Mhz vRam - Hynix - Then what's the Voltage and Heat - Better have a descent cooler?

An EVGA GTX 780 Classified 3Gb Hydro can hit 1900 MHz on Samsung vRam (not Elpida) at under 1.4v. I run 16 GB's of Samsung MV-3V4G3D-US_DDR3 at 1867 Mhz 9-9-9-24 1T @ 1.34v with no Heat Sinks in my rig and it breaks all Ram Benches.

 

[NostaSeronx]

If the GDDR5 bus is 16 * 32 then the ROPs will be 64. TMUs tend to follow the ROP count so it will come out around 256 TMUs.

 

[boxleitnerb]

ROPs can be independent from the memory bus width, see Tahiti and Pitcairn.

 

[yacoub]

Why the skip of 8000-series numbers?

Also, should be 4GB GDDR5 on the 7950 and 7970 replacements.

And won't new cards be DX11.2?

 

[Rvenger]

8000 series were a rebadge for OEMs only so they will skip that series naming scheme for retail.

 

[NostaSeronx]

ROPs can be independent from the memory bus width, see Tahiti and Pitcairn.

ROPs are independent of units not memory.

Tahiti on die has 48 ROPs of 16 are disabled. Sea Islands on the high end was going to unlock the full die at 1 GHz. This some how got cancelled as Nvidia wasn't being competitive enough. Thus, you see GCN aim its eyes towards Knight's Landing instead.

SI = R600
VI = R700

In relative performance leap for those who want to know.

GlobalFoundries will also be touting a design win for 20nm-LPM this year but, I am unsure if it is for AMD/Nvidia/SomeFPGACompany. It isn't a test chip, it is something that will be sold.
