Heheh, yes a flame war. How else do you discuss it sensibly? Forgive this post its about to go way off topic with bad typing.
*Firstly i should say that im an ATI fan partial to AMD, my last cards have been a 6970 and 6850, 4890 and GTX 260* So if you plan to read this with tinted glasses, make sure the lenses are green and not red if you want an even perspective please. Thank you.
TL;DR begin:
The 7970 is a good card, and so is the 680. The 680 is designed better for popularity and sales. Thats where Nv beat them. It will be the higher selling card. The seem to give a rats a$$ about the driver support too, so that should help.
One thing we can all agree on as fact is that Kepler IS FASTER than Tahiti. If you were to put both of them at the same clocks, the 680 can be 2-5% faster varying in titles and situations. 1100/1500 is a good comparision, the 680 still takes a slight edge. Thats what made it high end int he first place
The double edged sword or enigma or whatever is that GK104 could blow tahiti out of the water, rather than best it by 10%. If AMD wanted we would have a 1250/1800mhz Tahiti board, and if Nvidia wanted we could have a 1350/1800mhz GK104 board. (Okay if Nvidia really wanted we could have a 1000mhz GK110 board that would make every AMD fan STFU real quick.) The thing is, the 680 comes with 1gb less vram - for agruments sake that makes no difference except Skyrim fan-made HD texture packs and Triple screen 4xAA ultra BF3 or something equally egregious. The 7970 comes with a larger memory bus, and 3gb, but a complete lack of regard for how their fans interpret their multi-gpu and gameplay experiences. Nvidia seems to listen to the gamer crowd, pump them up, give them what they want, and support the gaming community. Of course they're gonna do that and expect an advantage or ROI. The downside is the low-cost pcb on the 680. You can argue that this is/is not low-cost, but if you read instead of whine you will see what I mean.
AMD builds the 7970 board, and seems to not even give a rat's ass if crossfire doesnt work on a triple A title, or if they don't have WHQL drivers out for 4 months. But amazingly the board is incredible. With an asus bios, you can push 1400vddc/1800mvddc through a very impressive array of power components. I won't go into detail on these components, but if anyone requests that I do, I surely will.
If you were to attempt to push 1400/1800 through that 680 ref pcb, it would be a fireworks display, excpet gk104 wouldnt be lighting on fire, it would be the sam-choice mosfets. GK104 can take the heat (or cool). So theoretically, if amd ever put out the super clocked tahiti (1200/1800), NV could easily build a robust board for gk104 and clock it at 1350/1800 and take the win right back from the new "tahiti product".
This whole argument lies in the fact that Kepler is so incredible compared to Tahiti. Kepler is a HUUUUGGEE win for Nvidia. Mainly cause NV was smart enough to survive with ginourmous dies like GF100 and GT200, while still being a money-earning company. If Sony, Nintendo and MS had time to see Kepler in action, then AMD would have no console contracts right now, Much less all of them combined. If Kepler and Maxwell continue this brilliant engineering trend, then AMD is SOL. and PS5, XBOX4, and WII U2 will all be nvidia.
But about 680 & 7970. Well despite the fact that PC gaming is about to be stalled by the next gen consoles (more than it already is today), Nvidia could technically drop in limited quantities their beast GK110 that we could all have a field day with. That chip is going to be so great, and AMD has nothing to respond with that I'm aware of. They have to have a 40CU + GCN in the works (like that rumored Tenerife slide) - which that slide is complete bs anyway, since it came from SA forums and is based off Charlies Canary/Sea/ "C" islands rumors.
Even if 'tenerife' isn't bs, then 40Cu Oc'd gcn2.0 probably still wont be able to take a 384bit/512bit 2304 CC Kepler on a clock-per-clock basis.
Stay focused here - about 680/7970. Here are some bullet points i consider factual:
The 7970 has more potential. board for board comparison there.
Gk104 has mroe potential than Tahitixt, chip for chip, clock for clock
Tahiti has more memory bandwidth (useful for shit like crysis, metro, multi dsiplay, multi-gpu extreme high res)
GK110 puts the memory bandwidht argument to rest.
680 is a more profitable, higher selling (faster performing) product than 7970
Nvidia is about to make a butt ton of money off Kepler, because they are already marketing and distribution magicians. They care about the community and being involved in game development. Their lack of engineering is the only thing that got AMD those console contracts, that and because NV had a costlier bid. Kepler is about to change all that.
Unless ati has some miracle performance metrics coming out of Sea islands, I don't see them beating kepler/maxwell. AMD's downfall is a whole different story, and now my fingers are tired and head hurts, and this is TLDR already. I bet the punctuation is headache-inducing too. sorry
Continuing right along! Amd is like a corporate de-evoluiton in progress, IMO (and far-fetched) 7970 was the "last great graphics board" from AMD. For many reasons... consolitis, weak next-gen consoles, amd/ati merger, small chip design, fusion evolution elements, intel's iGP, and Nvidia's compute strategy.
Nvidia supports HPC more than AMD, AFAIK, they lose ground on the fact that AMD is a veteran tenured company with a history of JEDEC, ISO, MS development. AMD/ATI is the reason for shit like directx and tessellation, but haha, now Nvidia can do that stuff even better than "GCN"
FOK "GCN" i love this crap. Virge disagreed with me when i told him Cayman was going to drop the T-unit and go for a 4-way very long instruction. He said that I should "humor him along with the rest of the folks in the peanut gallery". Well haha! I bet he knew all along it was VLIW-4 anyway, and was just egging me on back then. GCN is nothing more than an evolution of the freaking shader design resulting from the disaster R600. Rv670 if i recall happened right around the time AMD took over, and their design got smaller and more efficient. That rv670 vliw-5 design was great just like G80, and Kepler are. That design evolved into the 3870,4870,5870, and was altered at its biggest point at 6970/cayman. That is about the extent of development for them. I ask why the hell dont they make a 28nm cypress or a 28nm phenom II x4 for that matter. (oh yeah and faildozer doesnt make them seem any more ultra intelligent like something great is gonna come from the last few remaining bitboyz at ATI). ATI's falling apart. Well crap i mean AMD, ati is done already. Killbrew is gone, and look at all the management changes and ceos leaving and people being fired, that company is TOTALLY REFORMING. I hope something like the bitboyz R300 "respawns" from the pile of ashes when the dust settles, but somehow I doubt it will. Ati Canada is gone. DoomIII and R300 and G80 are gone. GK110 is the next BIG thing.
I remember anands old article about Dave Bauman and his elite dinner discussing (sunshine) or whatever was the codename of what was to become "Eyefinity". Thats a cool article for anyone to read. Check out the discussions on b3d, or just go enjoy your fav game on your 680, you lucky bastard. Historically ATI was always on the leading edge for engineering milestones, and I could be wrong but i dont see that happenign again. They were the first on every node transitiion at TSMC, they invented dx standards and tess, but now theres GF and TSMC, now theres Tri-gate and 20nm at intel's inhouse. Now theres the end of the road for standard silicon, the problems with tscm 40nm, 28nm and Nvidia's slides asking for new ways to earn money in lithography relationsihp with tsmc. Things are changing a lot. Nvidia could have their own in-house Tri-gate 20nm fab making SOC smartphone tegra shit in the next year or two. These are some reasons i thought the 7970 to be the last great AMD gpu. Gk110 better, and maybe the last big nvidia thing, untill the maxwell beast arrives. The environment is changing a lot around whats gonig on in the GPU landscape.
Nvidia markets better, we all knwo this. They have PAX, GTC, PDX, blah blah blah, and tons morer where that came from. They have "way its meant to be played" and a lot of other cool things that are really ntoable from a technicaly perspective.
My favs. That new ambient occlu in all the games from driver panel, that super quiet fan, and very compatible NVCP, fxaa, smaa, txaa, 20 different aa modes, 3d vision, and the glasses, even that stacked pci-e power connector thingy, Surround (copied from eyefinity) and now Kepler uArch with regular driver updates. I think Jensen was suprised himself when he said at the conference call that "kepler was tyhe best architecture they every made" It actually is really frickign good. The other good thing is that gpu boost that we're arguing about as auto-overclocking in thsi thread. That is a SMART EVOLUTION in graphics card design. They are squeezing the most out of their product which is in almost all ways better for us as the consumers. We win on every level, and the losers are the folks clamoring for ATI to add boost to their next gen 7970, when the reality is theyd ont give a shit and are busy making next-gen console gpus and reforming their company ranks. Just like nvidia is smart at evolving the cards themselves. Like begging for a change in the layout of intels motherboards, and the power limits of pci-sig. But this only lasted long enough until they had a faster card than the competition. Now who gives a crap about an inverted case where the HSF is ABOVE the gpu, and you can safely shoot 800 watts onto the video card. Nvidia makes Better designed coolers that allow for intake of air in a sensible way, Aerodynamic fan shroud. Nvidia card designs always looked like a ferrari to me, while amd's cards look like Mack dumptrucks. then if you were to compare Cypress to Fermi, Cypress is a ferrari while Fermi is a dump truck. Then if you compare Kepler to GCN, they're both high end ferraris, while kepler is a little faster and higher quality limited edition "Orange Lambo" if you will. But the cards, 7970 is still a dump truck and the 680 is an abosolule ferrari.
Now if you look at the PCBs... hehe 680 is a golf cart/moped/kia, and 7970 is a rolls royce, thats the only way i can safely put that, without trying to hurt someones feelings here. 680 owns in many metrics, but that PWM is not one of them. The power delivery is weaksauce, try and debate me on it, anyone im begging you to make a sensible argument about that power design. PLEASE!
Kingpins' billy-badass 680.5 board is a perfect example. He soldered a video card ON TO A VIDEO CARD for crying out loud. Yeah it set the record, but is it even a 680 anymore?... I mean jesus. LOL. It's a friggin space ship, not a graphics card.
Okay 680/7970 war, one more time (stay focused man) The 680 wins... But is it that easy? The 7970 has the world record. Andre Yang and Peter beat Vince and his alien 680 space ship technology, but only because Vince couldnt put 4 gtx 680 space ships on one Motherboard. With just that one sample at the uber 2Gz, he beat Andre's previous world record (which Vince argues is a cheated record anyway because the of the tessleation giving andre an extra 1-2k points). But hey Andre is a convicted cheater any from years past, and he was only last year unbanned from the XS community. But his cheating was because he knew how to get high scores and he would share them with others for money, not because he was faking the score he is a LEGIT bencher. Monety- Thats why he got banned. EVGA and Vince getting that 680 score above Andres 1.7g and Elmors 1.8G 7970's was a Press Statement more than anything. He said, let us inject this gk104 board with a friggin lightning bolt and see what happens *although you knwo behind the scenes he was begging Nvidia for a GK110 Engineering sample* but they said no, fok you You cant have a sample because if you set some super high retarded score, you're gonna want to show everyone, and there will be a massive riot cuz everyone wants that kind of performance. Yes folks, Kepler is a beast.
The very fact that he was able to beat a 7970 with a gk104 should tell the tale, regardless of how weak the 680 reference board is. And the 680 reference board's pwm is not all that "WEAK" per se really since it does its job and makes people happy by not exploding. Its not weak in that sense, its more like the pwm is "just enough to get by" with some little bit of overclockign headroom to boot. It OCs some, but they still stop you at 1.2v for the F of it. Make room for the primo models, like the Classified, doesnt hurt my feelings.
In the end if I had both a 7970 and a 680, somebody may wonder, what would this lunatic do with these two cards?
Well I would overvolt both of them. I would first off want the 4GB classified with the extra power and 14phase pwm for the 680, and i would go with a dual x sapphire 7970 or a watercooled lightning or something. I would probably put them on water blocks and oc the fark out of them and would want to sample many cards of each, since I know overclockablity differs by sample. But sadly I have neither, and my opinion is invalidated. Ride it out on my 6850 while i play borderlands at medium res, med qual...
you got 4 ppl
guy 1: My 680 ocs like shit, only does 1095 on baseclock
guy 2: my 7970 ocs like crap, only does 1080 on baseclock
newbie3: woah guys my 680 must be good, runnin fine at 1320/1800
newbie4: check my 7970, its at 1375/1950.
The factors at play are #1 VARYING SAMPLES. Somebody whos really good at overclocking could get a sample that stops them at 1080mhz - MURPHYS LAW. Someone who sucks and is newbie at overclockign could get a sample that is golden, best every seen, rarest, and be stuck at 1050 because he cant figure out how to unlock CCC limits or something dumb, or doesnt evne know how to OC in the first place. Like "oh i run stock" and that guys card might be the 1400mhz jewel diamond in the rough.
So you have to knwo what you're doing and push it to the limits, but you also have to get a good sample in the first place. Thats why those guys have 20 GTX 680s or 20 HD7970s in the same box, cuz they're testing them all for the rarest finest sample they can find.
Nvidia is winning right now. The strategy is great $499 680 GK104 (which they could only produce 200 of them before TSMC problems ramping big lots) Props to anyone who got one early. 256bit bus, and it still rocks the competition. Tahiti is good, and going by that OC review from Hard, they can both OC really high, but in the end, the OC 680 still bests the OC 7970. HOW-EVER the WORLD RECORDs are still held by the 7970. Not sure how to approach this, but it's definitly not as clear a win for as say 4870 versus 280 or 5870 versus 480 or 6970 versus 580. In those generations, the X80 beat the X870 eight times outa 9, not 50/50. Even when you overclocked both to their limits, the Nvidia top end still won, and they set all the HWBOT world records, this is the real MAJOR difference.
The 680 is not doing that. They could sell it at 460/560 prices and there would be no difference on the company spreadsheets. The last minute OC and name change was genius. The oem bios + 300.63 driver clocked it at 705mhz, the finalized + 300.99 at 1006/1058. It is engineered to be a high-selling, high-margin product that will be enjoyed by the masses and covers all bases. It overclocks, it does 3d, surround, plays all the games. Its a good product. It's not the Gx1x0, it is the Gx1x4. This says a LOT. It says Kepler is radical, game-changing and billy-badass in general. Kepler is the FTW graphics technology of the future, and is the nail in the coffin for the cursed GCN. I would love to have a 680, and thats part of the reason I hate the damn thing so much! Call me jealous or whateva/ I dont care. Its a wonderful product. It is a tad expensive, but you can put some of that on AMD for ripping us off on the 7 series (compared to their awesomely priced 3870/4870/5870/6970 that is). If Nvidia wants they could play this poker game and not show their all their cards... WHAT? NO WAY... GK110 is what AMD better watch out for. It's going to be a death blow for sure.
And the 20-25% rumors are because
1, gk104 is clocked higher than normal,
2, 110 will have compute centric built in because its being duplicated to Quadro, Tesla workstations and HPC,
3, the rumoured ratio of specs for 110/104 is not as big a gap in Kepler as it was in Fermi,
4, the probably wont have to make 110 a 1ghz sku since there wont be much comp.
Kepler was the big Nail in the coffin. Now time will tell the story of next-gen consoles, and GK110/maxwell/Sea islands.
Props if you read this. head hurts now. gg.
