Report: Specifications of AMD's Hawaii GPU Surface

By - Source: 3DCenter.org | B 56 comments

Specifications of AMD's upcoming Hawaii GPUs have surfaced, and they are nothing other than impressive.

A report from a German news site, 3DCenter.org, has shed some light on the specifications of AMD's upcoming 'Hawaii' GPU. So, without further ado, let's list 'em!

For starters, the chip will supposedly feature up to 2816 stream processors, all of which will be split among 44 different clusters. This means that each disabled cluster takes along 64 stream processors for weaker cards. In all likelihood, the Hawaii chips will feature either 32 or 48 ROPs along with about 176 TMUs. The chip will be built on the 28 nm lithography and manufactured by TSMC. It'll feature the GCN 2.0 architecture, as well as support for DirectX 11.2. The GPU is expected to be clocked at 900 MHz or above. The memory interface will be a 384-bit wide memory interface, carrying GDDR5 memory, though no reference capacity was mentioned in the report.

The report also indicates that it expects the performance of the flagship 'R9 290X' card to be between the GTX Titan and the GTX 690. Needless to say, AMD is directly taking on Nvidia's GK110 GPU.

AMD will likely be showcasing the GPUs next week, with sales starting around the mid-to-end of October, starting with the Radeon R9-290 (Hawaii Pro) and the Radeon R9-290X (Hawaii XT).

    I'm sure I posted once, not 4 times!
    Tom's, fix that bug!!

    The 290X is supposed to be a dual GPU successor to the HD 7990. At least according to Videocardz.com. That does not make it very impressive to be between the Titan and GTX 690. The 280X is the HD 7970 successor.


    I would assume that's a typo then and the HD7990 is already near the GTX690 and there is no way with more SPUs that it would be slower than the HD7990.

    I assume they meant R9-280X

    Well 5 more days till AMD "announces" it.

    The rumors have went from doubling SPUs to a small increase to this which seems promising if true.

    Hopefully they also get driver performance up in time.

    I have been waiting for these gpus for seeming for ever god let them be real. Keep up with amd. Make the drivers better and better

    looking forward to this launch. hope its as impressive as it sounds.

    Now, just price them nicely.

    hmm, similar clocks, similar memory BUS as the 7970, and really not THAT many more stream processors. thus, the performance per stream processor has to go up significantly to land between the Titan and the 690.

    if AMD can pull a 28nm chip Titan killer out on a 30% smaller die... I can't wait for their 20nm chips LOL

    7970 has 2048 stream processors. This has 2816, about 40% more. Add some architectural improvements, and it could get pretty close.

    From what I have seen the Titan is generally 30% better than the HD7970 GHz.

    This will also probably be based on the same GCN arch that went into the HD7790, which when OCed could contend with the HD7850 in some cases so I would assume there will be decent performance buffs for the R9-280X.

    I am hoping for more VRAM though. 3GB is nice but would prefer 4GB or maybe 6GB. But that will also make the price less attractive.

    Well, it's still got the 384-bit bus. You're likely to see multiples of three for memory, so probably 3GB, maybe 6GB.

    They might do a 4.5GB though.

    The GTX Titan is a mess anyway. Poor performance for 7.08 billions transistors(vs. 4.3 for the 7970), but it is a broken Tesla K20.

    I see newegg Canada has a Titan on for this evenings shellshocker @ $940. Still too much thou. I won't shed any tears during it's burial. And it will be interesting to see what these mature 28nm yields out of TSCM can do. Although... yawn

    I'm really looking fwd to 20nm as well!
    @vmen, agreed!!

    This is great news. I assume the introduction of AMD's next-generation video cards will drive down the current 7000-series price even further. Maybe I should wait a few weeks or months and see how prices end up before I snag a video card for my new build.

    An overclocked GTX 780 can match a GTX 690 already.
    Proof? See these two articles side-by-side:
    http://www.hardocp.com/article/2013/08/14/galaxy_geforce_gtx_780_hof_edition_review/
    http://www.tomshardware.com/reviews/catalyst-13.8-frame-pacing-crossfire,3595.html

    Compare the average fps results for Crysis 3, Far Cry 3, Metro LL, and Tomb Raider.

    Crysis 3: GTX 780 OC = 44.6 avg. fps / GTX 690 = 39.6 avg. fps
    Far Cry 3: GTX 780 OC = 50.2 avg. fps / GTX 690 = 82.4 avg. fps
    Metro LL: GTX 780 OC = 65.0 avg. fps / GTX 690 = 69.3 avg. fps
    Tomb Raider: GTX 780 OC = 55.7 avg. fps / GTX 690 = 47.6 avg. fps

    The GTX 780 OC loses to the GTX 690 in Far Cry 3, ties in Crysis 3 and Metro LL, and wins in Tomb Raider. I realize the settings used in both articles aren't identical, but they are close enough for a reasonably fair comparison. Keep in mind that a GTX 780 is a SINGLE GPU card and yet it is doing battle against a top-of-the-line dual-GPU card.

    Finally, at $689.99, the overclocked GTX 780 sets the bar that AMD has to beat:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814162142

    Will AMD bring out a comparable single-GPU card? They'll be in trouble if they don't.

    amd needs... NEEDS to be super competitive. titan has been out for quite a while now, and with the lack of competition, nvidia prices however the hell they want

    They wont quite be in trouble if they do but it wont help pricing or competition at all.

    I hope AMD is as I don't like the idea of $600+ top end single GPU setups. Even $500 is a bit pricey.

    I am optimistic they will push the GTX780. Honestly NVidia did it because they knew AMD wasn't releasing anything and could drop a gimped Titan with less VRAM and then rehash the 600 series and make a profit.

    Titan died the second the GTX780 came out. If you could pay $700 for a 780 and get near the same performance, why pay $1000? The performance difference was not worth the extra $300 Titan went for.

    Same as the price for the 780 didn't warrant anyone with a 7970 nor a 680 to really upgrade.

    Now if it gave 50% or better performance, sure maybe it would justify it. But honestly NVidia is just price gouging to inflate their margins.

    Honestly though I think anyone with a HD7970 or GTX680 could probably wait till well into 2014 before needing to upgrade as games still don't truly push them (except at 4K res which only the ones who can afford quad CFX/SLI could afford anyways) and wont until the new consoles are more saturated in the market and games start to use the DX11 hardware more.

    Even then they might not even flinch as both series were designed more for DX11 than anything and still do very well there.
