AMD Radeon HD 7990 Clock Speeds and Core Config Confirmed, Tested

[EarthDog]

Says the dude who only runs a single 7970 or GTX690.

Do keep in mind there are a huge number of Crossfire users here on TPU that DO agree it's an issue, and as big of an issue as related, so you'll have a hard time convincing those that use Crossfire there's no problems, and that's it's no big deal.

See, I can be a broken record, just like you.



EarthDog: Not a big problem. No I don't run Crossfire.


Xzibit: Yeah, it's an issue....but look, NVidia has the same problems!


Also keep in mind, that W1zz does relate the same issues as being evident, in his reviews, before the PCPer stuff came out. Frankly, nobody really cares about PCPer, as all they showed is WHY we have issues in some instances, but doesn't provide a fix.



Why not just put your opinion on the subject in your signature, and not post? The less you post about it not being an issue, the less you'll find others posting that it is.

Ran it.. dont need it. 690 was essentially a gift so that is why I run it as opposed to any 1,2,3, or 4 7970's that I have had in the past. I would be running 7970's in CFx if the ones I had fit in my case.

Frankly, nobody cares about people blowing this out of proportion. As I said, is it an issue, yes it is, for some people, not all, not on all titles at or most even. CFx is not "useless" as some fearmongers have stated.

Here is my exact take on this in fact. As a team, instead of fearmongering like was done at many sites/articles...: http://www.overclockers.com/nvidias-fcat-gpu-testing-pursuing/

@ Math - I have always noted this is a problem, just not as bad as A LOT of people have made it out to be is all.

Seams to work that way. Nvidias issues didnt get that much play even tho it affect more than just multi-gpu setups.

My reason is its not gonna help much by trolling about it. It's just making the forum dummer and perpetuating the Green vs Red mentality.

A better example is what Nvidia users did. They flooded the Nvidia and its Forums for a fix and Nvidia responded 5 months later with drivers that minimized the issue.

Obviously its not a hardware fix since it was apperantly affecting Nvidia both in Non-Vsync and V-sync situations and in Single and Multi-GPU sitiations.

Are there issues fixed ?, No. but you dont see reviewers or as much forum play out of it outside of Nvidias own forum.

Information is there from all the PcPer information has dumped that in single GPU Nvidia has catching up to do to AMD but that not the focus right. No its multi gpu and the same data is showing how horrid the variance is past 1080p Nvidia at there current "Driver Fixed" state.

Driver releases are changing that for both camps and i suspect will continue to keep changing.

You said it yourself. AMD is aware of it and is working towards a solution.

How well served would the forum be if AMD users pointed out that Nvidia has worse variance in single gpu comparasons on every Nvidia news post. Would they be happy until Nvidia releases a statement on it or even after that provided a time window for improvements.

Eventually those "post" show up by those people.

The reliability monitor shown above disagrees with you. When installing Crossfire affects a system's integrity, there's a HUGE issue.

Crossfire is useless. Simply, my "qualifications" for what I consider "working" and what I consider "not working" are different than your own. Yet as much as I am critical of AMD, here I sit with multiple AMD GPUs in the system I am typing from right now...and AMD's driver crashes have BSOD'd my system no less than three times already today. Let's forget frame latency, and talk about REAL issues.

Personally, I don't have any Nvidia hardware, so I have no idea about what issues they might have. But the fact they do or do not have issues does not minimize AMD's issues, for me. It's just simply not relevant to me, since I hate Nvidia anyway.



Please do keep in mind that I am in no way TPU's "spokeperson", My opinions are my own, and do not reflect the opinions of this website, contrary to what EarthDog's link above seems to think.

Perhaps there was something lost in the English to English translation... nobody stated, inferred, nor alluded to you being a spokesperson of TPU. In fact it clearly says the truth... you are a "reviewer" and "posted a thread" which we linked.

Typical fanboy crap. Problems? STFU don't talk about them here! It is ruining my ego.

That is a real issue, but where are the hordes of people experiencing the same thing? It can't be universal as people run crossfire without those issues.

Uh...

I am one of few users here on Windows8. That's why you don't see many others.

THIS THREAD IS ABOUT THE AMD HD7990 FFS!!!!!!

Go and squabble elsewhere!!!!!

Somebody moderate the thread please!!!!!!!!

 

[d1nky]

Lol

Or it means it's not universal. It means we have no way of knowing. Drivers, come!

I dont want cadaveca to shut-up. I think hes FRUSTRATED that he spent his hard working money on something that should be working better for him.

The information has been put out there and its fact that it should be working better for him since the competition managed to improve it a year earlier. So it is possible.

I think he is smart enough to know that but when someone frustrated there frusted and thats that. You just cant help it. I think its worse for him cause hes staring at his issue 24/7 <-addict.

I'd go do a WOD or something to cool off.

You're right, Xzibit. I am pretty frsitrated, so I do have pretty strong feeling about AMD releasing a card that "supports" Crossfire in a way that is fundamental to it's ability to work right. I've waited now 18 months for some nice working 7-series Crossfire drivers, and Win8 drivers since Win8 launched.


I did take a break for several months...

Now AMD's kinda saying they are going to fix it...and I am a bit loath to believe them, since there are many many issues here, and the whole frame latency thing is a just part of it. I really hope AMD pulls this off, honestly, and if they do, I'll be one of the first to buy.

Sweet jebus... our author took a lot more writing freedom than I thought there Dave... my apologies. Had I seen that before, I would have never let it get published like that. That said, I can see how he that impression however...

Heh, It's not a big deal, but I do try to make sure if I raise an issue, it's a real one. Like Frame Latency.


Sorry, couldn't help myself with that one.

 

[EarthDog]

Touche kind sir, no doubt its a real issue for some!

We are looking in to changing that around a bit, for the record...

 

[Akrian]

I'm looking forward to the release of this card. It will force ( hopefuly) AMD to fix some of the crossfire issues. If only we ( crossfire/ trifire quadfire) users could get performance like in BF3, only in every game heh.

Thanks.


My posts in the forums are all my own, and never reflect any opinion TPU as an entity might have. I am not under the employ of TPU.


Personally, TPU is W1zzard, GPU-Z, and all of us users. When I stop doing board reviews, everything else will continue, and I'll still be a user.

@cadaveca, earth dog, frick:

I too am running Windows 8 and 7970 crossfire. My cards are overclocked and run 24/7 for WCG, and they only stop when I stop them to game. I said it before: I don't deny the issue of frame latency, and yet I still maintain that it's not as bad as most proclaim, similar to EarthDog's stance.

I'm not particularly addressing Dave, as he may be more sensitive to things like that (I don't get sick from anything in my system), and/or he may be more attune to noticing slight stuttering. Id also bet that most are not at Dave's level, inclouding myself. I have noticed little things randomly, like minor stutter or whatnot, but nothing that has been major.

My games don't crash, and my system runs maxed 24/7. My pc rebooted once during the night a while ago while crunching, not sure why, but it hasn't happened again.

Recently the only issue I had was Crysis 3 crashing a few times, and that turned out to be an unstable overclock. I backed it down 15MHz and it's been fine size.

So tl;dr
My system runs 24/7 and runs well. Yet, I look forward to the newer drivers from AMD, but til then I'm still fine, as most probably are.

And on topic, I'm stoked for the 7990

Don't forget that CrossFire runt frame problem. This means that these figures will be totally false and hence real world performance much lower until AMD fix this problem.

Note that these problems mostly disappear when either vsync or just a single card are used.

Have not run amd cards in some time so I can't really comment on the specifics of the issue. I will say if you're running a multicard solution with the above bolded and underlined setting off, you're going to run into issues. Mafia 2 on 480 sli was nearly unplayable with it off at launch. Flip it on and it ran like butter, still does. Now if you're still getting massive issues with vsync on, then I'd think about swapping. But to me a simple settings change shouldn't justify backlash.

again haven't run amd since my 2900xt (and tbh I actually loved that card) so I can't speak to current issues. But even with nvidia multicard solutions, you need vsync on.

AMD DUAL GPUs

Am I the only one that noticed that both texture and fillrate have more than doubled compared to the 7970 GHz Ed with the same amount of ROPs and a higher clockspeed?
If these are Tahiti chips like the ones used in the 7950 en 7970 series, they should have a lower texture and pixel fillrate at 1GHz.

I wonder what they did to the chip for this to be possible(two typos seem highly improbable to me, unless the table is fake ofc)

Edit: Humansmoke gave me the somewhat obvious answer

Regarding problems only involving non-sync with AMD, I would not have problems for those mentioned problems below because I sync my screen frame rate [60Hz].

 

[ViperXTR]

nvm

 

[n0tiert]

I would love to have that card running in my rig, that´s for shure......
my last two cards where 4870x2 / 6990 and this one will definetly kick greenboys butts !
and yeah the 4870x2 still runs great on latest game titles so it was a good investment.

may i´m blind but the dual card runs great, never had a chance to compare a dual vs. 2 single of same type GPU´s and didn´t realize micro stutters, btw who has time in e.g. BF3 to fetch it ?!

i hope W1zzard will get his hands on it asap

 

[EarthDog]

Yeah you run that beats on a 22" monitor... go boy!

 

[Krneki]

There is truth here. I wouldn't touch a Crossfire setup until this problem is fixed.

Hardware wise, ATI cards are better, but if you want a reliable experience you pay the extra for Nvidia drivers.

i also have a 40" FullHD Samsung, next .....
