9000 series GPU to pair with your FX9000 CPU! Vegeta would be proud.
8000 series is exactly the same as the 7000 series. There aren't even any clock speed increases:
This is quite true, although I reference it as Hainan as that is the accepted rumor-monger place-holder for the chip everyone expects to be 1792sp. In the end it's really just semantics until we know what it's actually called. It seems odd to reference it as simply the successor to Pitcairn.
As for 2304sp, I still do not understand how people believe this will be a native spec. It makes no sense. Not only from a product point of view (the first salvage sku is a 7970 with not needed rops?) but also efficiency.
With 2304 shaders, your mainline efficiency would be at 1111/6000 from a clock/unit pov. The same as 1536 or 768sp and respective smaller buses. Using faster ram doesn't make sense because a clock would not be reached to absorb the bw for efficiency...hence it almost certainly being a salvage part. That doesn't stop them from releasing it first and harolding the full part later as the value high-end second-coming to make as much money as possible off early adopters, but it's just not realistic (especially since 48 rops would allow for 40-44 units) for that to be 'it'. It would be a severe waste of resources.
As for everything else,
Bonaire at 1100/7000 would be essentially equal to 650ti Boost.
Not-Hainan Le/7870 will take on 660...the former probably with 1pci-e connector (150w)
1536 1xxx/6000 would be fairly similar to 760.
1792 11xx/7000 would be very similar to a 770, slightly slower but conceivably use less power (225w).
(Get why nvidia refreshed their lineup as such? AMD is predictable and they preempted each important product with similar-to-better than expected performance.)
780 is clocked expecting a 2560 part at 1000/6000. I think that AMD will take the over/under on that (2304 at 1xxx/6000 and 2560 at 1xxx/7000) hence creating a market between 770/780 and 780/Titan. Truth be told, 780 should be the most efficient with regards to units/rops/bw, but AMD's arch won't be far behind and will be good for clocks/units/bw...and in theory should be able to clock higher within the same tdp because of smaller die size granted somewhat off-set by need for greater external bw (higher mem clock).
I think i read somewhere that 7790 had GCN 1.1 due to which it had nice power saving - plus some of 7790 tweaking reached 7990 as well, due to which 7990 doesn't eat double power compared to 7970.
Maybe this series of cards may actually be new technology instead of Kelper 2.0 from Nvidia
oh man...the memories. that 9800 xt 256 mb ddr2 edition with copper heatsink. saved up for months to get that thing when it released. hands down, best gpu ever. stupidly overpowerful for when it came out though. (late 03?)
put that on a pair of oced 1.5 ghz pIII chips and 2 gb of sdram....man, that machine was awesome. if only the motherboard hadnt died....
The best videocard they have EVER made was a gigabyte Maya II 9700 PRO, a true piece of ingeneering. I still have mine laying behind me in the box with a Abit motherboard and a 462(AMD xp 2200, Oc'ed to 3.2Ghz) and it still rocks on win 98 with a good old game.
On to topic, i really hope the new engine CGN 2.0 till be better to take care of the microstuttering thats all that matters for me to get a upgrade.
I have 2x5850 in xfire and to my need in games thats just about enough playing in 1920x1200, but i want a new screen 2550x1440 or even the new kid on the block, the Asus 4K screen, im going to need GFX power in the end.
If 1 cant do it then i have to go xfire again.
From what i've read once 20nm isnt a issue, AMD has 3-4 fabs to its disposal including TSMC.
But i agree if they release 2304core then it will be just between 780- Titan perf., 2560core would win, no doubt.
Imo these graphs speak for itself...:shadedshu
Those graphs speak of more speculation and rumor. Not to mention they don't seem very accurate as far as comparison.
It was that 9700 Pro that converted me to ATI Radeon [/QUOTE]
I still have my 9800 pro on my bookshelf in fact I also have 2 radeon 4850s one 5870 next to it running out of storage room I'm still using 2 hd 6950s . AMD should send me a thank you note for putting all their kids thru college .
Maybe, but its aprox. timeline says that real VI 9000 (Q4 2014) is still a looong way to go..
This series sounds like a tunning on the HD 7000 series to get more perf/watt, by the way we saw the improvements on kabini igp and 7790.
I'm waiting a new pricewar... get a ~780 perf. card going to ~350$ would be nice.
And Amd can make an oficial overclocked 9970 edition to troll the Titan
Here's the one thing that makes no sense... What’s the wait? Obviously AMD has had such designs waiting in the wings.
Consider what they got from Malta; although we never knew if those aren't cherry picked Tahiti's, or had true improvements for power. It pretty much indicated once production could provide lower leakage chips... things have the ability to improve. While Bonaire, seemingly good return on performance and power usage, while only receiving GCN 1.1. Perhaps a more sophisticated boost algorithms, true GCN 2.0 enhancements, with higher quality production might be some if not most of this 9XXX series, but why the wait?
Figure even if AMD held off like mid-April; at that point it was "dried in concrete" to everyone what Nvidia had planned, a re-spin their GTX 6XX. Even if AMD held back to that point to finalize product specs and send to fab, wouldn't they receive volumes of die candidates, send to AIB’s and have SKU’s for sale, I though that was like 18-20 weeks meaning more August-Sept.
October’s pushing 6-7 months, what gives?
Sales of current series is still good. It's about making money afterall.
So basically what I am getting from this is that I am good with my 7850's for awhile.
The Ati Rage Fury pro and K6-2 is what pulled me over to the Ati/Amd kingdom and been with them since.
Im personally ! Dreaming! of a 20nm miracle and it would be a miracle.
The top cards will have 2 or 3 GB of VRAM I wander...
1 GCN 1.0 core < 1 GCN 2.0 core
Also, GTX 780, and even GTX 770 for that matter, use more power than a R7970... so I dont know what you mean...
much faster same power draw at 28nm theres no way AMD can increase performance to match while dropping power consumption also know one knows how good GCN 2.0 will it seems to be more of a VLIW 5 to VLIW 4 change to me which resulted in little performance difference
Going from previous AMD gpu changes
at the same process node
they will gain 10-15% max and increase power draw at peak by about 40 watts.
THe GTX 780 is roughly 18-22% faster than the 7970 GHz edition, this would mean going by previous AMD design changes and performance increases that if GCN 2.0 is much like the VLIW 5 vs VLIW 4 change then the new HD9000 series would be slightly slower than the GTX 780 unless AMD is willing to push the power draw much higher.
THis means AMDs gpu will probably peak at 260-270w in a game and hit a maximum of 300-315w in likes of Furmark while being slower. Only way to counter act that would be higher clocks, which requires better binning = higher prices or even higher power consumption.
Having owned every high end AMD gpu since the HD 4000 series, my past experiences tell me AMD will equal the GTX 780 while being slightly cheaper but will run hotter and have a much higher power draw to achieve it.
4870 1gb was 13% slower than the 4890
5870 was 12 % slower than the 6970
7970GHz edition will most likely be roughly the same difference.
4890 was 27% slower than the 5870
6970 was 23% slower than the 7970 GHz edition added 9% on to that for a 31%
Thus looking at past changes at the same manufacturering process it can be expected that the 7970 GHz edition will be around 12-15% slower than the HD 9970 or w.e AMD calls it which as it stands is not enough to make the leap to beating the GTX 780, AMD wont risk pushing out the GPUs untill they can beat it soundly by a few % points in order to prove they are "better"
Regardless it wont matter much if AMD can rival the 780 while being cheaper COnsumers win. I just do not expect the gains everyone else does.
Vliw 4-5 ,??, I don't see it, and I think all the focus being placed on shaders might mean naught.
To me the details aren't there on gcn2 but I'm expecting a design aimed to differentiate via Hsa tweeks , after all ioummu or whatever it is has arrived and at rev 2 + ie established, and they are pushing hsa hard now , there Will imho be full dx11.2 support in architecture and therein another possible advantage.
Sounds like a pretty mediocre card -- I sure hope it is more powerful than it sounds (they need it to be at least 80% faster than 7970). 4K resolution monitors/TVs should hit mainstream markets next year at latest and tests done by various websites proved that even a single Titan cannot pull off any decent framerates at that resolution. In fact, even BF4 alpha testing shows that current gen cards fail miserably at getting anywhere close to high settings in next gen games, even at 1080p. Current GPUs have all had great value thus far against current 7+ year old consoles but when next gen consoles hit, Nvidia and AMD need to bring their A-game and at least double the performance of every tier of cards sold for the same price as current gen cards, otherwise nobody will buy them (who wants another repeat of ATI's 2900XT? Nobody, but we all want another Nvidia 8000 series to follow up to next gen consoles).
Well things somewhat went in "free-fall" with the 760 release and subsequent stock and price that GTX660Ti had been holding. As soon as folks got a look at the 760, price on GTX660Ti tumbled and pressed the last of the GTX660 to fall on the GTX650Ti Boost.
On the 78XX, now even 7850 2Gb are like $165 -AR and 7870 have been at $180 –AR having to slip with the GTX660 GTX650Ti Boost sell-off. Now yes AMD probably still has substantial chips for both in the channel, you figure all such wafer capacity shouldv'e moved off the Pitcairn and onto Hainan. I think they'll slowly bring them to a trickle to try to re-attain a pricing of $160/$210. As much as the 7790 was to back-fill the 7850 1Gb's, I think they're here to stay, vying what is the GTX650 Boost 1Gb.
I think a bulk of 79XX Sku's started slowly drying up after the 780, with most AIB's holding with just a few nicer Boost/Ghz offerings while maintain acceptable stock levels. Most all the more generic stuff (not Boost/Ghz) have already been waning. I think AMD and there AIB will finish out the summer aiming to recapture most of the what's the respective $270/410 price points.
I don't think AMD can see enjoying making less money on Tahiti/Pitcairn parts, and possibly even some sales being taken by "suppose" new models from Nvidia in the sweet spot of the enthusiast market. Sure if they've huge volume in the channel, but why are they in that position? There's been an abundance of time to work out such a transition. It's as if someone dragged their heels on switching scheduled 28Nm wafer starts from Tahiti to Curacao / Pitcairn to Hainan. The process is the same, they certainly held a schedule wafer starts, the design/engineering has been in place by all accounts, but somehow here they are 5-6 months in a holding pattern. Is it only me that it’s not making sense?
The only thing is if they had made it like August it could be 6 months till a Volcanic Islands, if they stay with October they’ve just a 3 month lull.
Hard to believe they will keep the same performance increase like they did back in the day.
3870->4870->5870 Ah good days.
Historically it has been up and down. 80% would be fantastic for sure, but it won't happen and it can't happen.
