AMD "Hawaii" R9 290X GPU Specifications Revealed

Here are the first set of specifications for AMD's next high-end GPU silicon, on which the company will no doubt carve out several SKUs from. Codenamed "Hawaii," and slated for unveiling on the 26th in, well, Hawaii, the 28 nm chip is what AMD will take NVIDIA's GK110 silicon head-on with. It is based on AMD's second-generation Graphics CoreNext micro-architecture.

With an estimated die-area of 430 mm² (18% bigger than "Tahiti,") the chip physically features 2,816 stream processors (SPs) spread across 44 clusters with 64 SPs each (a 37.5% increase over "Tahiti"). The chip features four independent raster engines, compared to two independent ones on "Tahiti." This could translate into double the geometry processing muscle as "Tahiti," with four independent tessellation units. The memory interface of the chip is expected to be 384-bit wide, based on the GDDR5 specification. Given the way TMUs are arranged on chips based on this architecture, one can deduce 176 TMUs on the chip. The ROP count could be 32 or 48. The chip will feature hardware support for DirectX 11.2, including the much hyped shared resources (mega-texture) feature.Source: 3DCenter.org

EDIT: this increase in efficiency not be true, see my post below



The R9 290X is clocked 16% lower than the 7970 GHz Edition but has 37.5% more SP. If the performance of Hawaii scales linearly with SP and clock speed with respect to Tahiti, then based on the TPU performance chart the R9 290X should be 97% as fast as GTX 780. If a dynamic boost mode is implemented (ala 7790) as has been rumored then they should be neck and neck in performance, possibly with the R9 290X being a little faster if it can boost over 1GHz consistently. However, as with any product the price is what will really determine a winner. But even if the R9 290X is priced the same as GTX 780, the R9 290X should be the better buy.
Nice calculations but 290X will actually be 7-12% faster than TITAN.

don't ask for the source

Did some math hear if this chip is anything like "Bonaire" well hears a speculation. "Bonaire" is a 29% increase in SP count and this results in roughly a 25% increase in performance. This chip "Hawaii" at 2816 is roughly a 28% increase in SP count, so.... Well you see the pattern hear.
I'll be honest I'm a little disappointed, I was expecting to see 20nm, but if this card can bring 780 levels of performance at $500 or less :rockout:
Aside "Bonaire" proved to have little impact on power consumption (5-8%), but applied to the 238w of power consumption this chip (regardless of the lower clock speeds) is gonna be cresting 250w :banghead:

Price is a speculation atm.. If you ask me 499$ is going to be the prive of the reference card.

The performance on this gpu is going to rock Nvidias socks off for the time being and I can see the Titan dropping to the 6 bill range just a few dollars more for the green crowd to be happy against the Amd 9 gen even though these are going to perform Tess and tress alot better, A LOT better then the 7970's :pimp:

must say this is one area where amd never disappoints.....true it must surpass nvidia or its meaningless.... nvidia will drop prices though.......
NVidia will never drop the prices of their two top end cards, because they see the high price of the cards as the cost to be a part of the green team. It's always been that way. Even if something performs identically to a Titan in every form, NVidia would still put a higher price on it compared to said identical card, purely for the right of passage into the green team.

I think they shot themselves in the foot with Titan. By keeping DP compute fully enabled with 6GB of RAM they sold their previously 'several thousand dollar' compute card for cheap. That would have probably annoyed a few small scale compute users that paid top dollar. I could see Titan just disappearing from inventory and a new GTX 785 (or something) that is a Titan without DP compute, 6GB memory but has higher power limits.

Nvidia only need to do that if the AMD card beats Titan. To be fair - it should. Titan is about 25-35% faster than 7970GHz. AMD's next gen card should surely be 30% faster than it's previous gen?

Titan isnt a full chip though is it? (Or am I thinking of the 780 when I say 1 cluster disabled?). So if something did beat the Titan from AMD, NVidia could happily rebrand the Titan 785, disable the DP Compute, and then release a Titan(Ultra?) with the extra cluster enabled - essentially the full quaddro chip.

1. Create hype with unrealistic spec. Diagram
2. Silently lower spec till release.
3. Profit.

Neh.

64 ROPs/ 512bit if you want to start the party.
A party, indeed! :rockout:

I'd still touch myself with 48/512... 64/512 would be full on FAPfest :laugh:

If these cards are as good as i'm hoping, i'll have one around the new year i think :)

@ 54thvoid: IIRC Titan is ~ 23% faster than 7970Ghz.

And what did nvidia pay have there cards made $3.74C :laugh:

Either way were getting the short end of it all :eek:

I assume English isn't your native language. "on par" means "equal to".
Therefore, if RCoon's assumption is that the 290X is equal to the 780, how can it have greater performance than the Titan which is around 8% faster than the 780?
Quite simply it can't. It is contradictory. There is no outright performance metric for reference SKU's where the 780 exceeds the Titan.
I did get what he meant, but 8 % faster Titan cannot and will not justify 350$ higher pricing.

EDIT: And about that performance metrics where 780 exceeds the Titan - please see this - http://www.techpowerup.com/reviews/EVGA/GTX_780_SC_ACX_Cooler/26.html

EDIT 2: The above review clearly shows, there is not much to overtake once you are done beating 780.

You do have to take into account that HD 7790 is pretty damn bandwidth starved, you know that right...


God, I love all you guys getting your nerd on and doing all that pseudo-pointless math and all... but there's so many things that you have to take into consideration... by the time you're finished one of 2 things will happen:

1. You're going to look like a clown when you realize you forgot about factor X or Y or Z.
2. The card has launched anyway so it's redundant.

Example one: Has anyone forgotten about AMD's uber driver overhauls that kept on enhancing and squeezing more and more performance out of the GCN arch? Maybe this will happen again (or maybe not), but this time, they have their shit ready day 1.

Thank you for the information.
The criticism, not so much. Anyway this is all speculation :toast:

I don't think the driver will fail this time. GCN has been around for 2 years. And AMD will smart enough to not release a new chip that cannot beat 780.
Now that will only be the price. If AMD bundle the card with BF4 for the same price as 780, who can resist to buy??

if you bought a Titan just for gaming, you should probably reevaluate your purchase.

I don't think it'll cost as much as the GTX 780, then again I don't like the speculated $599 price either, considering HD 7970GHz's predecessor (HD 7970s...) launched at lower than both those prices and that was pretty frowned upon. Remember the "OMG and it's only 30% faster than GTX 580!?" reactions, I do...

In a sense this would be the same as the 6970/Cayman hype. Remember, Cayman was planned to be 32nm, and all the early specs were based on that. But at the (relatively) last minute it was moved back to 40nm and cut down to make it a reasonable die size. I would expect the same here - Hawaii was expected to be built on 20nm, TSMC couldn't deliver, and it was moved back to 28nm and cut down in size.

Stop trolling. The postings were concerned with - and only mentioned- relative performance of three cards- nowhere was pricing used until you just bought it up. Classic straw man argument.

What part of "reference" don't you understand?
by: HumanSmoke

It may have escaped your notice that the EVGA GTX 780 SuperClocked isn't a reference SKU.
From the article that you linked to, here's W1zzard to explain the difference:
The card is factory-overclocked and offers out-of-the-box GPU clock speeds of 967 MHz core and 1118 MHz GPU Boost against the 863 MHz core and 900 MHz GPU Boost of NVIDIA's reference board.

Oi! That's precisely what I did :laugh:

At time of release Titan was far ahead of any other single gpu solution - that's why many folk ditched more 'powerful' but very buggy dual gpu solutions. Who'd a thunk Nvidia would've screwed us over with the 780? :ohwell:

But on topic, I'm looking forward to seeing what the new AMD flagship has to offer.

Titan is still miles ahead of the 780s imho, the added shaders when pushing 1300-1400 Mhz make a BIG difference.

And I dare to say it will be at least 30% faster then 780GTX/Titan, if 2800+ core then even more, kinda like 580GTX vs 7970Ghz

Its not miles ahead. Especially if you only consider gaming performance, for $300+ difference is not worth it. Now if you do things that need compute power sure, since Titan has the full blown double precision compute still intact.

And that Chinese site leaked some benchmarks too, actually a lot!
http://udteam.tistory.com/539

Like I had a thought 10-40% faster then Titan., Newer drivers will fix the rest, 7000 series driver boost anyone and extra 150-200mhz OC and its a killer gpu ;)

imo not bad at all for max 600€.
