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

Ahead of its April 24 launch, AMD board vendors has been distributing marketing materials to their retail partners. One such retailer in Japan revealed the flagship graphics card's specifications sheet, revealing details such as clock speeds and GPU core configuration.

To begin with, AMD isn't compromising much on clock speeds on the HD 7990 "Malta," in an effort to lower power draw. The card features GPU core clock speed of 1000 MHz, which puts it above the single-GPU Radeon HD 7970, but not much lower than the Radeon HD 7970 GHz Edition, with its 1050 MHz. The memory is clocked at 6.00 GHz, on par with the HD 7970 GHz Edition, which yields a cumulative memory bandwidth of 576 GB/s.

Moving on to the core configuration, the Radeon HD 7990 "Malta" doesn't disable anything on the "Tahiti" silicon. It uses a pair of "Tahiti" chips, with 2048 stream processors each, 128 TMUs each, 32 ROPs each, and 384-bit GDDR5 memory interfaces, each. The card features a total of 6 GB of memory, 3 GB per GPU.

In another slide, AMD gave retailers performance numbers for the Radeon HD 7990 "Malta" from its own testing. The HD 7990 is pitted against GeForce GTX 690 and GeForce GTX TITAN, and the three cards were put through 3DMark "Fire Strike" in performance and extreme presets. In performance preset, the Radeon HD 7990 scored 16 percent higher than GeForce GTX 690, and 29 percent higher than the GTX TITAN. In the extreme preset, it kept the trend up, scoring 15 percent higher than the GTX 690, and 31 percent higher than the GTX TITAN.

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

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

just not as bad as A LOT of people have made it out to be is all.
The reliability monitor shown above disagrees with you. When installing Crossfire affects a system's integrity, there's a HUGE issue.

Crossfire is useless. :roll: 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. :p

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.:p



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. :toast:

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...

[quote="overclockers.com]TechPowerUP! is also a Big Site and they aren’t running FCAT testing either. Their reviewer cadaveca started a forum thread on the subject and was very blunt and straightforward. While he was obviously expressing strong opinions about CrossfireX, he has some good insights in the thread, such as:


The real unfortunate part is the cost in testing such things is still prohibitive for nearly everyone.

and, when asked if they will be doing this testing, which meant their reviewers would need to do a massive amount of work, he said…

Nope. Just Ryan @ PCPER does. His new job is verifying that drivers work properly (whatever “properly” means). And as long as they are, every other reviewer can just keep on doing what they do.

…which is precisely what we intend to do.[/quote]I can't speak for GPU testing here @ TPU. I have nothing to do with that. I made that comment in a general context, and it's being taken in that post, as what TPU's position is. The only reviewer that has anything to do with GPUs is W1zzard, nobody else. I'm in charge of motherboards and memory. That thread was a post made, as a user, not a reviewer. It was posted in the forums, not the front page, since it really has nothing to do with TPU, and everything with my own personal feelings. I didn't even talk to W1zzard about it until after the fact. He does seem to agree that AMD has issues, but that doesn't mean his opinion sides with mine, at all. English comprehension issues, for SURE!! Nobody asked what TPU was doing...please re-read that post that says I said what TPU is going to do.

[QUOTE=Frick, post: 2889149"]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.[/quote]I am one of few users here on Windows8. That's why you don't see many others.

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... :o

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. :p Like Frame Latency.


Sorry, couldn't help myself with that one. :p

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. :p

@[USER=25138]cadaveca[/USER], 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 :toast:

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

by: Mathragh
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 :D
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].

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 :)

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.
