Not amazing but really good, decent IMO.
My 5870 needs to move aside and this will be it's replacement

He is on vacation right now I think.Where's the guy that was saying 1GB of vram is more than enough?
They didn't double the cores, they increased it by 30% and net about 40-50% performance.Great ..., they double their cores again for minimal gains. Maybe overclocked this thing can scream? If they hit 30% gains in some areas a hefty OC might give u a 15 to 20% performance boost which could be nice.
Certainly isn't anything exciting tho ... . Oh well, bring on Fermi @ 28nm :awe:
LOL
So I was right (alongside a FEW others) in our assesment of ~30% faster than a GTX580 in average.
I guess it's time to look over the threads and see who got chaught up in "SILLY SEASON TM"...and thus cn be ignored at next launch

Super disappointed, really not significant enough to bother with over my current 580s unless they turn out to be excellent and easy overclockers, hitting 20-25% OCs and scaling at least nearly 1:1 if not better.
The overclocking potential of the Radeon HD 7970 has been much vaunted in the recent leaks and it certainly didn't disappoint. Even without any software or hardware voltage mods, we managed to bring the CPU core from the default 925MHz up to the maximum 1125MHz that CCC would allow. We also turned memory up to 1500MHz and Power Control to +20% to prevent throttling.
Without batting an eye, the HD 7970 clocked right up to a completely stable 1125 MHz core speed and 1575 MHz memory speed. I can’t wait to get voltage control on these things. If it does that at stock, imagine what we can do with some more voltage available!
AMD representatives were quite confident about the Radeon HD 7970’s overclocking headroom. They went so far to say that most cores will make it over 1 GHz, that many will get past 1.1 GHz, and that some will even slam right into 1.2 GHz. Moreover, they claimed that the stock 1375 MHz GDDR5 memory could make it to 1625 MHz or higher.
We were happy to perform the tests needed to validate AMD’s claims. Unfortunately, the card’s stock BIOS is more of a prude than the company’s representatives. Its software-based Overdrive tool won’t push any higher than 1125 MHz on the core and 1575 MHz memory. Compared to the stock 925 MHz core and 1375 MHz memory settings, though, those are respectable ceilings for a consumer card. Of course, board partners will be able to customize the overclocking limits of their own offerings, and if the Radeon HD 7970 has the overclocking headroom that AMD says it does, we’d hope to see factory-overclocked cards with nice boosts.
The AMD Radeon HD 7970 comes clocked at 925MHz on the core and 1375MHz on the memory, but if you enter the CATALYST Control Center (CCC) you can raise or lower the clock frequencies within the parameters set by AMD. For this card AMD set limits for this particular BIOS to 1125MHz on the core and 1575MHz on the memory. The good news here is that the Radeon HD 7970 that we were sent for testing could hit these clocks without touching the fan control or power control settings! Not bad to get a 200MHz jump on both the GPU and memory for a seconds worth of work. Without any voltage mods AMD says that enthusiasts and overclockers should be able to hit 1.2GHz and if someone wanted to do some voltage mods that they might be able to able to hit 1.3 GHz! We don't want to mess with modding the Radeon HD 7970, so we stayed with the stock 1.1 Volts on the core and installed a new BIOS that 'unlocked' the clock limitations of the video card.
On our 7970 samples the fastest speeds we were able to achieve were 1115MHz on the core and 1510 MHz on memory. This is an increase of 190MHz on the core and 135MHz on memory, something which opens up a lot of potential for AMDs partners to enhance the 7970. It also increased our 3DMark score to X3124.

Actually "SILLY SPELLING TM" might be more suitable.....
Do not want.
Compared to my 6950, the 7970 jacks up heat and noise with only ~30% increase in performance. Add to that the ripoff price AMD is gunning for and this turd will sit on shelves.
TBH I was expecting way more from 28nm. I guess I should always assume I will be let down by TSMC.

25/30 percent IMO, I wasn't aware they were at 1500+ shaders with the 6970 already.
Maybe you should try Eyefinity?
Also,
Can we have a generic review collection thread without an editorial in the thread title? Let us be the judge if it is "disappointing" or not based on our own criteria.
Enthusiasts seeking the fastest will care little about perf/watt.AMD has, yet again, delivered the best Perf/Watt card.
It's certainly not a bad performer. Just wish the price was a bit lower.

I can only imagine that these really will only shine when you have at least 2 of them driving a multi monitor setup.
if only it was 30% faster on average, its more like 15%, and the few games where it even comes close to 30% (more like 25%) are games like Crysis and Metro where the frame rate is still too garbage to play on max settings with just one GPU (ie 30s) or games like Portal 2 where you're still getting well over 100fps on the 580 and thus really don't need any more GPU.
otherwise all the other major blockbuster games actually worth investing in a GPU for (ie BF3, SC2, Batman AC) the advantage only ranges from 5-18%.
so yeah, you were wrong, you don't get to round up just to make it look like your prediction was good
