What were people expecting?

1) The 780Ti is GK100

2) 980 is GM204 (i.e. the 770 replacement)

3) It's still on 28nm.

If you want the performance, wait for GM200 on a new node.
 
Oh and not to mention the supposed power draw numbers. It's supposed to be around 175W or so. You're getting around 780Ti performance (greater than 780Ti stock but obviously they're clocked very differently) for about 2/3rds of the power on the same node from the 770 replacement - GM204. How can you not appreciate this?
 
Why all sites (Guru3D included) report this like GTX980 is slower than GTX780ti?
According to this graph, stock GTX980 is 11% faster than stock GTX780ti (100/90).
Also the memory clock remains the same and despite that increasing the core clock by 6% they are getting 5% performance which means one thing.
256bit GDDR5 does not bottleneck this GPU! :O
 
prediction reporting....i'm not even going to bother reading and the chart means nothing with out a product. to me that's like the last 20 years of cherry picked weather reporting out of 4,54X,XXX,XXX billion years on one test subject out of a universe.
might as well be the 5 day weather forecast imo.

this revising of one particular chip design isn't worth more than spending $100 on and waiting 5 years for the next chip architecture design is better bang for the buck.
the enabling of shader modules that were previously disabled and the removal of memory interface chokes that are still subpar at best considering the 384bit and 512 bit interfaces of the 9000 & 200 series as well as amd's 3000 series.
i guess they can get away with it when the resolution has been restricted to 1080p for over 10 years. every one thank sony for this blockade in computer graphics/gaming that has kept consoles viable as a gaming platform and blurry pixelated movies over 50".
 


Well... keep in mind that these numbers are extrapolated from leaked specs and what we already know about Maxwell. They're purely synthetic, so take them with a big grain of salt. However the performance results they came to do seem surprisingly believable.
 


Yeah, I forgot to add that "if people at VideoCardz are not trolling...." 😛
 


I didn't say any of those cards use Tonga. I said "Tonga is based off of Hawaii", and many of the architectural refinements in Tonga are already available in Hawaii and Bonaire. Every 285 review I've read, including the one here on Tom's, has pretty much stated the same, that Tonga is essentially a further refinement of GCN 1.1. They went on to provide many examples of inherited architectural refinements from Hawaii. So I'm not sure where you're getting this "Tonga GPU is based on the Tahiti" from.



Haven't heard of Maxwell, or something? You're commenting in an article speculating about it, so I find this assertion a little strange.



Yaa, I don't think the image compression is going to result in much of a performance boost, if any. If anything its main benefit is maintaining performance on narrower buses and reducing the dependence on wider buses (like Maxwell), so I'm not sure why you're anticipating a big performance benefit from pairing a higher-end Tonga-like GPU with a much wider bus, or why you're anticipating Nvidia having trouble responding to these refinements when they essentially already have. It's not going to make a difference unless it actually needs that additional bandwidth, so I would think the goal of a refresh like you're suggesting would be to reduce the bus width as opposed to maintaining it (a la 285).
 


Tonga is not based off hawaii its off tahiti
pitcarin when reviesed will be iceland
hawai xt is going to become hawaii xtx
 
spentshells said:
so less heat more performance per watt while using the smaller memory interface while staying within the same generation spells bad news for nv in the performance war.

I was referring only to tahiti vs tonga for power requirements.

I would deffinately advise you try out google for any of these questions

bonaire is not using tonga revisions as it isn't using the same core (tahiti) but is based on the tech used for xbox and ps4 (xbox at least)

Yer really making a deal out of being told what is what and that isn't the point. Read a little more and you will see what you are saying is off and wrong.

 


...okay dude.

"Despite what its specifications may suggest, Tonga is not a spin on the Tahiti GPU in the Radeon R9 280 and 280X. Rather, it is a new and condensed version of the Hawaii GPU in the Radeon R9 290 and 290X."

"In addition, the Radeon R9 285 inherits the 290 series' quad-shader layout, allowing four primitives to be rendered per clock cycle instead of two."

"Of course, Tonga has inherited Hawaii's fixed-function hardware, too, such as TrueAudio (AMD's new audio processor) and project FreeSync (the open-source answer to Nvidia's G-Sync) support."

Tonga is two steps removed from Tahiti, and from an architectural standpoint it's obvious it's inherited a lot from GCN 1.1 (Hawaii, Bonaire).
 




You are wrong, sorry about that.

pitcarin revised is iceland
tahiti revised is tonga
hawaii xt when revised is hawaii xtx

Same website as the linked article.

No prob, it looks like icland is not pitcarin but will replace mobile and low end a la 250(x) and its related. Im wrong all the time just not now.

Bonaire is in fact the gpu used in xbox
custom deal

MASTER... as they say
 


There's obviously some sort of communication barrier happening here, because you seem to be consistently misinterpreting what I'm saying, and apparently (giving you the benefit of the doubt) I'm misinterpreting what you're saying. I never suggested Bonaire used or is based on Tonga... just chronologically that wouldn't make any sense.

And I haven't heard of Bonaire being based off the GPU in the Xbox, that's news to me. Could you provide a source? To my knowledge the GPU in the Xbox is based on GCN 1.0, not 1.1.

I'm not trying to be difficult here, I just really don't think you're right and I'm honestly confused as to why you think Tonga is based on Tahiti when there's been a GCN revision between them, and it shares so many architectural enhancements with Hawaii. There's just so much evidence to the contrary. Could you maybe provide a source says what you're trying to say?
 
No bro I dig, but I did provide the bonaire link to you, it was even in the toms article when released if I remember.

And I did provide the info on hawaii as well, as I mentioned thhough just google it, there is lots more info.

 


omg dude... you're either a noob or you're trolling or something, I can't tell at this point. The quotes I provided came directly from Tom's review of the 285, and reviews from other sites make similar architectural comparisons between Tonga and Hawaii. This is not coming from me, so I think your response would be more appropriate if you wrote "everyone is wrong". You just keep on banging your head into this wall of mounting evidence that I'm providing and you're not giving anything substantive in response. You just keep on saying 'no, you're wrong, I'm right'. I mean, it's like I'm arguing with a child here.

So let me get this straight, your rationale for why Tonga is architecturally based on Tahiti and not Hawaii is simply because it's intended to take the place of Tahiti in AMD's product lineup based on performance characteristics and pricing? Please tell me that's not what you're saying, because if it is you're seriously misguided, and you're completely misinterpreting what I'm saying, and what the article you linked is trying to say. It doesn't say anywhere that Tonga is based on Tahiti, it only says that cards based on Tonga are supposed to slot in at similar price points and performance levels as cards based on Tahiti. It makes no mention of a direct architectural connection. And it's basically saying the same thing about Hawaii and Hawaii XTX. That's totally different from what I'm trying to say, and from what I think you're trying to say.

And the link you provided as 'evidence' that Bonaire is based on the GPU in the Xbox... just wow. The author mentioned that in passing speculation once, and never addressed it again throughout the article. He was speculating dude, nothing more. Notice also that the article is dated about half a year before the launch of the One, in fact he's referring to is as the '720'. And he said he thinks the GPU in the Xbox will be based on Bonaire, not the other way around. What you're saying wouldn't make much sense since Bonaire launched on the desktop well before the launch of the Xbox One.
 
Are GPU's topping out like CPU's did a couple of years ago? Looks like if you bought an i7-2700K and a GTX 780 after the price cut you have gotten the most bang out of your buck then and for the foreseeable future.

LOL or if you got a 7970 3 years ago and just overclocked to perform the same as the silly overpriced 780.

Your going to get a 7970 equal in any situation to a 780.....

You do know a stock R9 290 trades blows with one right?

I would know... I just upgraded to an R9 290 from a R9 280X...

My OC 280x firestrike = 7577

My R9 290 stock firestike = 9559

My R9 290 slight OC firestrike = 10051
 
If this is true, I am deeply disappointed.

Unless, the heat is so much less than 780ti, I would be able to overclock it much further than my current dual 780tis.
 


Alright, you don't like being wrong, I get that, look around for yourself.

http://www.tomshardware.com/reviews/microsoft-xbox-one-console-review,3681-4.html

Pretty tired of this. You seem to think repeating what you think you've read is actually knowing something, it isn't.If you need more information, please I encourage you to use google.

I hope you figure some of this out on your own because you do not know what you are talking about at this time. This is a community not a classroom.





 


Well gosh you really think you're the shit don't you? Get over yourself dude. Even after parading around, what to any informed reader of this thread, would be your obvious misconceptions about architectural relationships in GCN, you're still doing this, deflect, dismiss, talk down "MASTER... as they say".


... because I'm responding to you?

Thanks for the link. First legitimate source from an actual review. I admit that the only hardware deep dive I've read on the Xbox One/PS4 were the two published on Anandtech, which made no mention of a direct connection to Bonaire or Pitcairn. But still, it was pretty easy to dismiss that first link you gave as dated speculation.

But wait, aren't you forgetting something? You know, the original topic that you've conveniently left out of your response while subtly suggesting for the first time that I simply didn't understand what you meant?



Seriously? In each response I gave I was trying to honestly clarify to you what I meant while deciphering your cryptic broken sentences. You antagonized, repeated, and escalated the argument with every response dude:

"Tonga is not based off hawaii its off tahiti
pitcarin when reviesed will be iceland
hawai xt is going to become hawaii xtx"

"You are wrong, sorry about that.

pitcarin revised is iceland
tahiti revised is tonga
hawaii xt when revised is hawaii xtx"

"MASTER... as they say"

Maybe you just aren't accustomed to responses? You are growing tired of this correct? If I misunderstood something about what you were trying to say, why didn't you try to clarify when it was happening, the multiple times I asked if I understood you correctly? Why only suggest a misunderstanding now in retrospect? Lame attempt to save face? Or are you really that much of a troll?

Instead of being intentionally vague and dismissive, like "You seem to think repeating what you think you've read is actually knowing something, it isn't" why don't you be real and tell me what I don't understand. How am I misinterpreting what I've read? Are you talking about the links I provided, or the crap you posted? I know I've already asked this but you've yet to answer it. For real, what do you mean?
