I am going to buy a new video card in the next 2 weeks, so I decided to get a Radeon HD 7990. I want to ask you if you know which is the most powerful Radeon HD 7990 (from the new 7990s) with the highest performance! I am looking forward to getting the Sapphire Radeon HD 7990.. Is there a better Radeon HD 7990 than it? Thanks in advance!

^Agreed

Right now AMD Crossfire solutions (which is what a 7990 is) aren't a good option given their FrameRating issues, and with the GTX780 coming out and being virtually identical to a Titan offers much better Price/Performance.

If you decide to go 7990 anyway, that Gigabyte Radeon mentioned is your only option, all the others are out of stock :p. From what I can tell their all pretty much identical anyway (except for the Powercolour 7990, but dont go for that since its an older 7990 model, designed by the manufacturers and not AMD themselves).

Yeah, right! The Radeon HD 7990 is light years away from GTX 780 and it's false that my only option is Gigabyte Radeon HD 7990! As you can plainly see, in my country - Bulgaria, I can buy Sapphire Radeon HD 7990 as it is not out of stock - http://outmax.bg/dmz/index.php?_a=viewProd&productId=48770 !

The price of the Sapphire Radeon HD 7990 which I am going to buy from the Bulgarian shop is less than 1000 euro!

Never said the 7990 is worse than a 780, just that the 780 offers better Price/Performance. The FrameRating thing I mentioned is also true, I suggest you look it up as it is a relatively new concept.

Then that's perfect for you, enjoy your Sapphire 7990 from Bulgaria. Since the vast majority of the people here are from North America, we kind of assume that retailers like Newegg are what your going to be buying from. If you wanted a more informed opinion on whats available to you, telling us that you are in fact from Bulgaria and buyong from that retailer would have gone to great lengths of clearing this issue up.

Anyway, that Sapphire card is your only option (being the only 7990 available at that site as far as I can tell) anyway, so why ask if there are any better ones?



Well thats great... and?

They are all reference cards so it does not really matter which brand you go with, they all come out from the same manufacturer and every board partner just sticks their name/logo on it with the exception of the Powercolor of course, so you could go with whatever is cheapest or provide longer warranty period.


But still like you have been told above, the 7990 is the WORST choice when it comes to the $1000 market cards, you are way better of with a GTX 780, a GTX 690 or a Titan, the GTX 690 being the absolute fastest and provides the smoothest and most solid experience, while the GTX 780 is a best value for money card for cards in that price range.

Unless OpenCL is your primary purpose of this card, i think buying the 7990 is a huge mistake for what it costs when high performance, high resolution gaming is what you are seeking.

You have been told and it is up to you how you want to proceed.

I asked, because there are many, many other Bulgarian dilers and web sites from which I can buy other versions of the card.. I have bought my Corsair Hydro Series H110 water cooling system from amazon.com, so I might have bought another version of Radeon HD 7990 from there as well, if it was the best and I couldn't find it in Bulgaria.

And why do those statistics exist, if the GTX 690 is so much better compared to the Radeon HD 7990, like you are saying?!

Notice the AMD and Radeon logo's in the corner? Would hardly call that an unbiased review.
Also all those tests are performed at very high resolutions (5760x1080 or 4K) which is where traditionally Radeon cards have always outperformed Nvidia due to their better memory systems. You want to be looking at benchmarks at 1080p.

Since this review came out, FrameRating was discovered and it is a significant factor. I really suggest you look it up, as AMD crossfire solutions really do suffer quite badly from it.

Also I should say, if your gaming at 1080p, a 7990, 690 or 780 are all overkill. Go for a 7970 if your just gaming at 1080p.

I'll play at 1920x1200! I am going to buy such a powerful video card, because I don't want to get a new one each year, and I want to experience extreme gaming at its finest! I want to have more than 100 FPS while playing the latest games, even after 2 years, that's why I am going as high-end as possible!

lol these are hypothetical frame rates and is not what you can see playing consistently and smoothly on your screen, and i wouldn't take charts from the manufacturer as a basis for buying their card, unless you believe that Ariel cleans better than Persil or the other way around because their TV commercials show them producing whiter clothes .. hahaha

Check the following review with Frame Time Variance or Frame Rating accounted for which provides a more realistic picture of what experience you should be expecting from the 7990 with explanation of why things are tested the why they did and why that provide a more realistic measurement of FPS

http://www.tomshardware.com/reviews/geforce-gtx-780-performance-review,3516.html

The market known facts are that the AMD Radeon cards provide very good value/performance for single card configuration, but if you want dual card configuration or is buying in the $1000 cards market, then nVidia provides much more mature and reliable technology and better cards.

No fanboyism involved here, if you are so much in love with AMD and would feel better buying their products for all configurations and all price ranges available, then by all means just ignore the advise you are getting here and buy yourself a 7990 and be happy.

To answer your question of which 7990 is best, i told you they are ALL EXACTLY THE SAME, because that is AMD's reference design, so buy whichever is cheaper, offer faster delivery, longer warranty or whatever better terms!

I am against the GTX 690 and 780 so much, because back in 2011 I bought a shitty "gaming" notebook with GT 555M - 1 GB GDDR5 and i7-2630QM! It went to the repairing service for absolutely everything and stayed there around 3.5 ~ 4 months all in all.. The card had huge problems, it lagged, skipped frames, froze, lowered the frame rate and crashed in absolutely every game, always!! I was happy if I could pull 80 FPS on Crysis (1024x768, all low) for 1 minute, before they drop to 20 FPS and stay like that for 15 - 20 minutes, not to talk about the unimaginable lag spikes which occurred every 5 - 10 seconds, making every game absolutely and totally unplayable! If I start writing about how many ways I've tried to fix the problem and what I've done, I'd be here writing till the end of next week and wouldn't still be done. It was insane!! I didn't have any problems with my previous laptop (HP Pavilion 2010eq) which had a much slower card - HD 4530 and a dual core AMD Athlon II M300 2.0 GHz processor.. Sure, I had 40 FPS in Crysis (1024x768, all low), but the game ran smoothly without any problems what so ever and was fully playable like all the other games.. I've actually beaten Crysis 2 on HD 4530 and despite the fact that I had around 15 FPS at 800x600 and was sometimes forced to play at 800x480 and happy to reach 20 FPS, the game ran pretty fine without any frame skips or major slowdowns, and I had fun, because the graphics weren't that bad as well..

which in your case i would indeed stick with AMD because you have got to the point where you are now paranoid about nVidia products and would indeed be happier with anything AMD.

That is a perfectly understandable situation because everybody's experience and preferences are different, for example i see most people swear by the Sapphire cards and perceive them as very good and very reliable etc.. for me personally my experience with my Sapphire card is very different because it caused me TONS AND TONS of problems and made me see anything Sapphire as garbage just like you see anything nVidia as such.

But again despite of your personal hating to the brand, the 7990 has serious problems, real problems that render it immature and problematic technology, now AMD has been promising better drivers that would fix the problem for a while, we are yet to see such drivers, and they may never fix the problem as it could be just the way the Tahiti chip is just is and in this case the 7990 will always work worse than the 690 until AMD comes up with its next 20nm based architecture that is supposed to have this issue fixed.

You are in somewhat tricky position, but sure if you will feel better owning a 7990 which i know you will, then just buy it, but don't have your expectations very high because you might not be happy with the end results.

For the most part, the current generation's crossfire introduce more problems and issues than they do helping performance.

It might not have even been Nvidia's fault for the bad performance, it quite easily could have been the notebook manufacturers or even the GPU manufacturers (because Nvidia sure as hell don't manufacture their chips) issue. Nvidia just design them.
AMD has fabs around the place for their CPU's (well, used too), so I assume they manufacture their GPU's in house.

One bad experience shouldnt turn you off one whole company, there are any number of reasons it went wrong and its not necessarily the name written on it. I could easily mess up any Dell computer I can find, and whoever uses it next will probably blame Dell.

After having to deal with the nightmare called Lenovo IdeaPad Y570, I decided to start building a desktop computer for myself, building it took almost an year as of the time of buying a new PSU and HD 7990. When I got a Sapphire HD 6770 for the desktop, I was absolutely amazed. I had 3 times higher frame rates compared to what I experienced with the 555M, I didn't have lag spikes or slowdown even in the most unoptimized games like Crysis 1 and every game ran perfectly.. From that time on, I decided to never turn my back at AMD and to never buy Nvidia cards again.. Some people may say that HD 6770 is nothing that good to be happy about and that it's a medium-end card stably going to the low-end, but from what I've experienced with the 555M, 6770 came as an upgrade from GeForce2 to 9800pro.. I have so much faith in AMD, that I am ready to buy their cards with closed eyes, which as you said may hide its dangers..

Great, so i think you have all your information complete at this point, and you are fully aware of what you are buying, then all is left is to just go ahead and make your purchase, nothing else can be said or researched further..

Now is your own personal decision time, good luck with whatever you decide to buy :)

but then in your situation it could be best to buy the 7970Ghz single card for now because for you it will be the best of both worlds, it is AMD as you like it to be and it is a proven and reliable technology being a single card without any of the immature crossfire component.

This card will be much cheaper than the 7990 and will last you for at least one year until AMD's Volcanic Islands 20nm Hawaii 9970 is out and then you can use the money that you saved from your 7970Ghz purchase over the 7990 to buy the next 9970 which will be in the performance range of today's 7990 and can be had for the money you saved this year by getting the 7970Ghz and will then last you for say a couple more years.

This way and with the same amount of money, you could have awesome gaming performance for say 3 years, all based on AMD technology :)

If i was in your position i would do exactly that, instead of spending so much money on the 7990 today when Volcanic Islands will be out in around 6 months

Or use that leftover cash from the 7970 and get yourself either a 3x1080p monitor setup or 1440p monitor, so then if you wanted to get a 9990 later on (I imagine by then FrameRating issues would be lessened given AMD have had most of a year to come up with a hardware solution + Drivers) you could actually benefit from its performance.

Youv mentioned before you want 100+FPS in games, most monitors cant even display faster than 60FPS. By increasing the resolution your placing more load on the GPU, therefore actually taking advantage of its extra performance.

and we are still not sure what this solution will be like, if the problem is hardware-based, drivers can only provide workarounds like limiting FPS to enhance rating or some similar solution, in which case the GTX 690 SLI solution will maybe faster as its chip does not suffer from the same problem.

I would not base my buying decision on a software solution that has been promised for long and has not become reality yet.

What we know for sure is that AMD can do so much on a 20nm node with a new architecture that is said to be re-engineered from the group up.

In all cases i wouldn't spend so much TODAY on a crossfire solution if i am willing to stick with AMD

Either buy a single card solution for now, or wait until June/July to verify the promised solution or save as much money as i can for the upcoming 9970 :)
