Yep, and will be considerably faster than the 6870 it's replacing, however, the usual derpers will derp.
Nvidia can release the 580 1.5gb for about £450 and no one bats an eyelid, it's just AMD haters, erm hating (and Martin and Alex

)
AMD haters hating? Over the past four years.
I came back to the UK in 2008 minus a wife. This means - PC porn !
First PC, refurb green Alienware for £280 (a return, basically) everything was fine in it apart from the GPU so I bought a 9800GT.
Then I found out that I paid £150+ for a card that was £130 or so with the name 8800GT. I wasn't best pleased but oh well.
Next card - GTX 280. Went pop, replaced with.
A shiny pair of 5770s.
In the meantime I set up a second PC with two
3870x2s to see if Quadfire was as bad as people said. It was. Infact no, that's too nice, it was worse.
Then I got a GTX 470. Cracking card with a Zalman on !.
Then when it ran short of vram I got a
6970 Lightning.
When that needed RMA I bought a
7970.
So I am no fan boy nor a hater of any company. I do admit I do have a few niggles with Nvidia bubbling away deep down inside me (their rebrands and trickery, and of course their 3DFX bashing that was uncalled for unless you're a greedy corporation !) but I will buy their cards if they meet the correct criteria.
The 7770 does not meet the correct criteria. Infact, if one was to use your argument and calculate how fast a 5770 could go if it could do 1ghz (clock per clock) then you'd probably find that the 5770 was every bit as fast as the 7770.
And I maintain, this is down to AMD. They should have opened more up on the 7770 to
clearly set it apart from its predecessors. They haven't, and they're asking too much money for it.
I thought Verdetrol was really funny. I did, it made me laugh loads, just as much as XFX's Power Rangers video. However, if you're going to try and be funny then you need to be clearly funny. When the 7770 released it just made AMD look completely stupid. Kinda like the time they did the videos ripping on Intel and then Intel came along with the Core 2 duo and gave them the biggest pimp slap
ever.
That came shortly after AMD's raging success with the Athlon XP series where they gave Intel a poggering. Sadly, as with many other things, they decided to get rather cocky and confident and were dealt numerous crushing pimp slaps.
They've come out and admitted that they can no longer compete at the top end. That's nice, that's honest. Now they are becoming clearly deluded with a minor success*
* I mean the 7970 of course. Had they priced it at £350 or there abouts it would have gone down in history. Not taking away from its prowess of course, but at the price it commands it will never be the stuff of legend.
