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.

at least i buy em from hard earned money instead of "showing off" with sponsor gifts..... poor world
Note the 1080p results on some games...
EDIT: And note, that is OK to do what you are doing, its just something I personally wouldn't do, no matter how I received the items. Waste is waste, ESPECIALLY if I earned that money and planned to spend it.

ONE 7970 is plenty and there 'if I needed it' at 1080p.
"EOF"
and that i´m still fine with my good old 4870x2 on actual game titles compared to the age/price of that card.... my 6990 is to "new" to tell how long it will last. may till 9990 ? who knows.
this was more like an personal quality/durability rating on choosing such product vs. single or upgrading every modell....
if you do CAD/GFX/ARTS, similar stuff or even simple nagios/zabbix monitoring i agree to have as much res as you can but then it might be betta to go on FirePro/GL or equivalent nvidia modell
gaming on 2560x1440 or higher is nice, no doubt but not an explicit musthave to defend the choice of dual cards.
i compared a single 6970, same setup, same Card Vendor, to a 6990 on lotsa game titles, benchmarks on my available resolutions, for me this was the right decision to go on 6990 by it results platform independent, twice a 6970 where same price to a 6990, 2nd thing is if you like to change cooler/fan and or go on wb it´s cheaper should be same on nvidia models aswell, so there is nothing complain about.....
if ppl like such out "of the box" products, let em have it :cool:
cmon
how to know what my card is not for other stuff in use like e.g. crunching.... ?
instead you get into a "Intel´s product line with ATI based dual GPU" commercial
and picking on a "FX" chip never mentioned by me or compared here in this thread ?
i cannot get the grip.
:toast:
Anyhoo, EOF and end OT and all that already can we?

First AMD 7990 Review is up
Benchmark - AMD 7990 Review (In Russian)
Come on TPU give us some nekkid PCB shots... :O
I'm such a fanboy of AMD dual GPU cards it's tempting me.
