Are new full fat Hawaii XT cards on the way ?

What ya gonna do Kaap?
Keep those poxy, stripped-down, cut-back, half-fat, under-powered 290Xs?

Yes

I am waiting for the next gen cards.

 

[Kaapstad]

Lol.
What a bloody tease, like i said in the other thread they must have a better cooler if they want to add more on an already power hungry card, unless their 'contingency' also comes with a more efficient architecture.

They could leave the cooling to the AIB partners.

Kap mod your cards to stop black screen benching. So much fun man. I am gonna go after so many records starting in a week or so now all my Lightnings are modded.

This should be interesting to see how the cards go with the better memory the lightnings have.

Good luck with the records.

I have noticed that multi GPU 290Xs seem to go really well on 3dmark vantage.

 

[Kaapstad]

I think they are clustered in texture units, 176, so divide that by 2816 = 16

Not much use ^^^

If we look at it this way.

290P: 2560 + 10% = 2816 (290X)

290X + 10% = 3089.6

Or, probably the way it should be worked out, 2560 + 20% = 3072

They seem to work around 256

10 x 256 = 2560 (290P)

11 x 256 = 2816 (290X)

12 x 256 = 3072 (290?)

290XT

Those numbers make sense to me too, so clock for clock we would be looking at between 5 and 10% faster, about 7% on avrage

In theory a 290X is 10% faster than a 290P, in practice as they don't overclock as well so it is about 7%. So yes about another 7% on top of a 290X.

Bugger I'm stuck with an old version of Hawaii.

 

[Kaapstad]

So many model changes, so when are these happening, kapp this year next year and btw id love to get stuck with that Hawaii lol

I don't know anymore than anyone else but my guess is if AMD release a higher speced Hawaii chip it will have to be in the next 2 or 3 months or there will be little point.

 

[Kaapstad]

My prediction is Kaap will have 2-3 of these on launch day for that important 10% extra

My prediction is I won't.

No point in buying less than 4 and if I did that they would bottleneck and be no quicker than what I have now.

Having said that I am getting close to buying a 4K monitor and it is a lot harder to bottleneck cards at that resolution.

I probably won't get any new GPUs until the full fat next gen cards are with us.

 

[Kaapstad]

This is just a question, dont take it the wrong way. Is 8 Pack sponsored by NV?

I don't think so, he gets gear from lots of different companies to test half of them are AMD based.

 

[Kaapstad]

O.M.#.G

They actually had an ace up the sleeve. You have to love that. Jen-Hsun Huang just spat his coffee all over his screen

Actually this is an interesting point and the question is why did AMD not launch a full fat Hawaii chip in the first place. The answer is they did not need to as they were selling as many normal 290Ps and 290Xs as they could make due to the mining craze. Now sales are down due to the drop in demand from mining this gives AMD the reason to launch the full fat version.

Yeah as usual it's never his fault, it's never harmless humour, instead of commenting on the topic it's just lets have a dig at nvidia from him as always.

The funny thing about his post is nvidia probably have something up their sleeve as well.

I don't think NVidia have got anything at all, the cupboard is bare. They can not give the cards more VRAM (the Titan BE has that covered) and they can not release a more powerful GK110 as the 780ti and Titan BE are already the full fat versions.

They could knock a tenner off the Titan Z I suppose.

 

[Kaapstad]

Rumor is Nvidia have got 28nm Maxwell parts coming, will probably wait until AMD launch the 295X to beat the 780 Ti and Titan Black, then Nvidia will drop the Maxwell cards shortly after with plan to have the lead again.

Wandering what they brand them, the 750 Ti is Maxwell, so I guess Nvidia could use GTX 785 or GTX 790 for a high end 28nm Maxwell card?

The 8XX series monikor should be saved for 20nm imho

I think these 28nm Maxwell parts are going to be a bit of a flop for NVidia looking at the specs. As soon as I read 256bit bus I thought to myself not again.

The real weakness of the GK104 cards is not the 2gb VRAM they come with but the awful 256bit bus that bottlenecks them. A 4gb version of a GK104 card still performs badly at higher resolutions. Heck even the 384bit bus on the Titan Z is showing the strain @4K with the performance dropping right off compared to Hawaii cards.

 

[Kaapstad]

What, you think that Nvidia (a multi-billion dollar company, which is worth 3 times as much as AMD) doesn't have any sort of back-up or contingency?

Companies of this scale always have something close in the pipeline.

Not always.

I don't see a lot of 20nm GPUs yet and how long have we been on 28nm.?

 

[Kaapstad]

In a couple of years, memory bottleneck will be all but eliminated when AMD and Nvidia stack chips. Bandwidth will skyrocket and in that respect make all of today's GPU memory speed irrelevant.

The Maxwell 28nm cards will likely be very fast and power efficient, but as you say with a 256 bit bus may suffer at 4K. I think the 4K market right now is about 1%, so the Maxwell cards could still appeal to gamers who are @ 1080P / 1440P.

When 4K is mainstream much much better GPU's will be available to use. Wouldn't worry about 4K much until then..

Both AMD and NVidia have got to take note of the performance @4K when they launch a new high end card even if only 1% of people are using the resolution. The point is the review sites are using 4K and buyers who want the fastest card will be swayed by the 4K results (they will also think about future proofing). A good example is the Titan Z review over at Guru3d where the 4K results make the card look even more of a joke than it is.

Of course Nvidia have an answer, ridiculous to think otherwise tbh . They have been one step ahead each time AMD drop a GPU..

AMD dropped 7970, Nvidia answered with 680 plus
'Nvidia Titan'
then followed with 780 (Took the lead)
AMD answered with 290X
Nvidia followed with 780Ti / Titan Black. (Took the lead)
If AMD drop full fat Hawaii, Nvidia will answer for sure..



Agreed. GTX 790 (Maxwell) 28nm. Plus price drops on GTX 780 / 780 Ti.

AMD dropped 7970, Nvidia answered with 680 plus
AMD sorted the drivers and sold shedloads of HD 7970s and outperformed the GTX 680.

AMD have also sold shedloads of 290Ps

The only thing NVidia could try is a GTX 790 but we already know where that is going as the Titan Z performance is very poor. The thing NVidia could do with a GTX 790 is to watercool it which would make the card err more expensive.

If NVidia really want to compete they need to sell their cards at realistic price points.

This would be more down to the lack of ROPS rather than the memory bandwidth. In the 295X2 vs Titan Z comparison the latter has more memory bandwidth (336GB/s vs 320GB/s).

The ROP throughput/Pixel fillrate on the titan Z is theoretically much lower than the 295X2.

~876Mhz x 48 = 42GB/s (x2)
~1000Mhz x 64 = 64GB/s (x2)

Back on topic the release of the "Full fat" 290XTX doesn't really change much at the top end. The 780TI will still end up (marginally) quicker in most review benchmarks, whilst user reviews / more in depth benchmarks will show rough parity across the top end cards (clocked up of course).

Overall, meh.

You are making my argument for me

How many ROPs is the new NVidia card said to have.

3,200 CUDA cores, TMU's: 200, ROPS: 32, Memory Bus: 256, Architecture: Maxwell.

This card is starting to look like an epic failure at high resolutions and oh that 256bit bus.

 

[Kaapstad]

Goes both ways, the 7990 launched at a ridiculous price only to tumble to half its price later in the year. Just wondering how long before the 295x2 takes a dive in price.

+1

I think we have had a hint from OCUK, I can see them selling for about £750.00 in a couple of months time.

 

[Kaapstad]

Teabreak

Time for a cup of tea.

 

[Kaapstad]

Don't give up hope, IIRC the sites were all wrong about Hawaii specs.

I hope NVidia get it together as I want to build a 20nm + Haswell-E green machine early next year.
