>>”Power Connectors: 4×6-pin + Cooling: Triple-Fan” = Bye-bye, Radeon HD 7990! This is madness!

it’s just too much power connectors. It’s unconstructive! And TDP probably will be about 400 Watts that means 750-800 Watts PSU as a minimum requirement. And need to use three-fans cooler construction caused by necessity to reduce a huge heat and means really big noise. And now look at the GTX 690: it’s small, silent, fast, cold, takes only 300 Watts and need just 650 Watts PSU. And if HD 7990′s price tag will be about $700 – it’s worth it, if more – it isn’t.

Another shitty card from amd and one more epic fail.

2 GB of VRAM is still enough for 2560×1600. This mode uses about 1.6-1.8 GB at ultra graphics in most games with MSAAx4, 1.5-1.6 with FSAA or FXAA and 1.3-1.5 with TXAA antialising + AFx16 (which is doesn’t really needed, just lowers performance).
And Dual-GPU graphics card cannot be compared with two single-GPU cards is SLI or CrossFire mode. Two single-GPU cards are always more effective in most cases. And you compared 915 MHz GTX 690 with two 1050 MHz HD 7970 in CF mode. What do you expected, huh?
And HD 7990 probably will get lower GPU clock to keed TDP lower than 400W, or there will be too much power consumption and heat. If HD 7990 get 950-1000 MHz GPU clock the TDP will grow up to 450-500W and temperature will be about 95-98 degrees at 100% load. That requires 850 Watts PSU and water cooling system! This is insane! But if GPU clock will be 800 MHz the TDP will drop to 375-400 Watts. But 800 MHz won’t be enough to beat GTX 690.

Agree, HD 7990 will be a fail: high power consuption, high temps, driver problems/scaling, noise.
Such “four 6-pin power connectors, instead of two 8-pins.” is funny at least :)
AMD just need to do their job, but forgot 1st place(faster chip) with their CPU´s or GPU´s, just like in older days, Performance/Price/Quality ratio.
Give “vitamins” to their cards 7950/7970 is not the best solution IMO, only for some fanboys that will always buy AMD, without looking for other directions.
They lower 7000 prices now because GTX 660 Ti launch. HD7870 at $300 was ridiculous, and because of that Nvidia join the party and also put 660 Ti price tag at $300.
If AMD had put fair prices at launch, Nvidia also did the same and we all benefit of it.

I usually see on foruns, people still complaing about drivers, even with new 12.8, they say that 12.4 still most stable…
Users complain about crash after some minutes of gaming, but it can be unstable CPU or GPU OC, defective card, Power supply…almost of them have High End cards.
One thing that people forget are Pirated versions, that can go wrong sometimes.
Anyway, if/when 7990 launch let´s see what gonna happen.

1) Some games are exceeing 2GB of VRAM at 2560×1600. Max Payne 3 and Sniper Elite 2. Why would anyone spend $800-1000 on 2GB cards? GTX670 4GB SLI or HD7970 CF are way better options than GTX690.

2) That GTX690 has GPU Boost, so it’s actually faster than GTX670 SLI 2GB. You can read Xbitlabs review I linked to see exact GPU Boost they got.

3) I agree with you that HD7990 is pointless, but to me so is the GTX690. Those cards only make sense for people using small cases.

Performance wise, I already linked you that GTX690 Quad-SLI is just 5 fps faster than $900 HD7970 Ghz Edition setup. This is because at 2560×1600, a single HD7970 beats GTX680 and HD7970 Ghz is even faster. Here is even a GTX680 4GB and it loses:
http://tpucdn.com/reviews/Point_Of_View/GeForce_GTX_680_TGT_Ultra_4_GB/images/perfrel_2560.gif

GTX670 SLI is perfect for 1080P, while HD7970 GE CF setup is perfect for 2560×1440/1600 or 3 screens.

NV cards have huge problems at high resolutions due to memory bandwidth bottlenecks. But the 2GB aspect I mentioned is because when next generation of games launch, it won’t be enough most likely without using FXAA or TXAA.

I have gamed with Fermi, Cayman and Tahiti chips. I don’t have driver problems with NV or AMD cards. The ones that happens are usually with new games and they get fixed with game patches and later drivers from both camps. You can read driver problems on both sides if you ask honest users.

I think AMD should make a 7990 with a single Tahiti Xt 2 core with a few tweaks like the 4890, making it the most powerful single GPU card on the market. If so, my guess is 15% more power than the GTX 680. A pair of such card will kick GTX 690 in SLI mode in the nuts.

7990 canceled

Ya, it’s probably going to be coming from PowerColor or AIBs only if they want to. It was delayed too much which gave 690 all the head start and how many people out there want a $1000 dual-GPU card in the first place? In that market segment you have to be quick and NV beat them by miles.

Stock for stock: Ghz Edition 1050mhz 7970 could have been named HD7980 or XTX if AMD wanted to. Those are the specs from the factory. Here is even HD7970 Ghz vs. GTX680 factory overclocked 4GB version and it still loses to the 7970 Ghz:
http://tpucdn.com/reviews/Point_Of_View/GeForce_GTX_680_TGT_Ultra_4_GB/images/perfrel_2560.gif

You said GTX680 can also be overclocked? Yes but 7970 OCed vs. OCed GTX680, the 680 still loses. Already tested by many websites, here is yet another review to show you that was published just days ago:
http://www.xbitlabs.com/articles/graphics/display/msi-n680gtx-lightning.html

Go look at the benchmarks of HD7970 Ghz edition vs. GTX680 MSI Lightning. 680 costs way more $ and can’t win.

You can troll all you want, the data are there and it proves you wrong:
$430-470 HD7970 Ghz editions = quiet with after-market coolers beats $500-600 GTX680 cards stock for stock or OC vs. OC overall.

Sure there will be some games where the 680 wins such as BF3, but there will be other games where 7970 crushes the 680 and that list is WAY longer:

- Dirt Showdown
- Anno 2070
- Sniper Elite V2
- Sleeping Dogs
- Bullet Storm
- Batman AC with 8xMSAA
- Skyrim with ENB Mods / 8x MSAA
- Trine 2 with SSAA
- Alan Wake series
- Arma II Operations / Day-Z mod

The games where 680 will win:
- BF3 (single digits % lead)
- Project Cars
- Lost Planet 2
- HAWX 2
- Crysis 2 (single digits % lead)

For that ^ NV charges $70-170 more! Enjoy paying that premium.

Ya, my point was that NV ripped us off like AMD did too. 8800GTX for $600-830, GTX280 for $650. HD7970 launched for $50 more and had 20% more performance than a 580 with original drivers and no overclocking considered. What was AMD supposed to do launch an HD7970 for $369 you are saying?

So what do you want exactly $369 HD7970 vs. $499 GTX680 that was 3 months late? That would have been fair to you? AMD did what any business would do is to maximize profits with no competition. NV would have done exactly the same, stop kidding yourself. They did many times before like I said with 8800GTX and GTX280/260 series.

Also, not sure why you are bringing fanboysm and other stuff into your response. The point is at today’s prices AMD offers higher price/performance at every price except possibly GTX670 depending on where you live. Right now HD7850 has no NV competitor and goes for $190-210, HD7870 goes for $230-240 and HD7950 goes for $300-320 over here, HD7970 1000mhz editions are $420.

I am not seeing AMD ripping customers off especially since many believe GK104 is just a mid-range Kepler and NV sells those for $400-500. So, who is ripping their customers off exactly? BOTH companies are doing it. At least on the AMD side, you get more performance for less $ via overclocking and you have the option to bitcoin mine on the side profitably at least in North America.

20% using launch drivers boss. Right now HD7970 is = GTX670.

1920×1200 = http://www.techpowerup.com/reviews/Sapphire/HD_7970_Toxic_6_GB/28.html
GTX580 = 73%
GTX670 = 88%
HD7970 = 89%

GTX670 and 7970 are now priced comparatively. I don’t agree with that AMD PR slide you posted btw!

This is how I look at it:

HD 7970 Ghz competes with 680 at $430-500
HD 7970 competes with 670 at $370-420
HD 7950 competes with GTX660Ti at $300-320
HD7870 has no competitor at $240-250
HD7850 has no competitor at $190-220

Oh if you friends bought HD7870 for $350, that’s probably because GTX580 was $350 when they bought that card. It’s like me telling you “Oh my friends bought GTX280 for $649 and then I got an HD4890 for $175 12 months later. My friends are NV fanboys.”

You are blaming AMD for setting high prices but:

1) NV was 3 months late with GTX670/680
2) NV was 6 months late with GTX660Ti
3) NV supposedly held back GK110 and shoved us with $500 GTX680 mid-range GK104 :(
4) Why should HD7970 have launched for $450 when it beat a $450 GTX580 when it launched and had 30% overclocking headroom, next generation DX11.1, 4K tv support, better power consumption, 3GB of VRAM, Compute functionality?

It doesn’t make sense. AMD did what any company in the world would – raise prices when there is no competition. Like I said NV did that with 8800GTX and GTX280 back in the days. Don’t pretend there is some double standard that AMD raises prices only.

What I am saying you can’t say HD7970 was a rip-off at $550 and then say $500 GTX680 wasn’t a rip-off either. If you want to say that this generation is too expensive because NV held back the real GK110 (aka GTX780 possibly) and that HD7970 and 680 should have been mid-range $350 chips, I won’t disagree. As it stands now, AMD is undercutting GTX680 with $430-450 HD7970 Ghz editions and those are actually faster than the GTX680. In fact, even the $550 GTX680 Lightning cannot even beat a 1050mhz HD7970 Ghz edition. So AMD is bringing similar performance for way less $. I realize it’s very expensive for you but I am just saying HD7970 is just as overpriced as GTX670/680 are.

Keep in mind NV itself keeps ripping us off: GTX460 768mb/1GB launched at $199/229 and now NV is charging $299 for GTX660Ti mid-range? Since when did mid-range become $300? See that’s my point: both companies raised prices this generation. 8800GT and GTX460 were amazing values but there is no such card for $200 this round. I think it’s amazing that 660Ti launched now. Because of that card AMD lowered prices on the 7850/7870/7950 and made it more affordable. For $230-240 the 7870 is delivering ~ GTX580 $500 level of performance 1.5 years ago. That’s not that bad, since it uses way less power. You gotta remember it’s still 2x cheaper than the MSRP on the GTX580 was and nearly the same speed. So we did get some improvement in price/performance; it just took 8+ months from 7000 series launch to get it.

3 new games already use DirectCompute by the way:
- Dirt Showdown
- Sniper Elite V2
- Sleeping Dogs

It’s not a huge factor yet but compute shaders are already starting to be used in some games for global illumination/lighting/HDAO. What I meant when I said compute is that you can do other things with the HD7000 series like accelerate WinZip, Photoshop, render in LuxMark. Now it may not matter to you, but those features are free.

How expensive is electricity rate per killo-watt hour over there? It’s about $0.15 per KwH, so a 225W 1150mhz 7970 is costing me $24 to run a month 24/7 99%.
