Radeon HD 7700 Series Specifications Surface
In the coming week, AMD will release its Radeon HD 7700 series, which aims to increase its competitiveness in the sub-$200 market. The latest specifications exposé reveals AMD's new design strategy: Instead of increasing components such as stream processors and ROPs, which would increase transistor counts, and unnecessarily increase power draw, AMD is counting on a lesser number of better-configured Graphics CoreNext stream processors. While the previous-generation HD 5770/6770 "Juniper" GPU featured VLIW5 stream processors, the new "Cape Verde" GPU, which will go into making up Radeon HD 7770 and 7750, will feature GCN stream processors. Apart from architectural performance improvements, AMD is counting on increased clock speeds to do the trick. The specifications are listed below.

With the ridiculous prices of HD 7900 series, I am now looking forward to HD 7800 series (and Kepler to reduce prices due to competition)
they will be roughly like 6870 and 6850 while using very little power.
this is standard for amd.
thx for nothing, AMD!
Based on that I presume 7770's performance will be less than the 6770 cos 7770 has 640SPs and 6770 has 800SPs.
I think AMD are doing this deliberately ... may be they want to show a huge jump in performance when they release their 8xxx this year (rumored).
me dont like :(
Here's hoping it beats the HD6770 by a margin worth speaking of.
I remember in the 5xxx series when the 5770 used to be half of the high end 5870 and now this.
Let's go, benchmarks!
and not preformance per $ :(
This is just lame...
Then the 6850/6870 will again elevate in the product mix.
And......again......what can you buy with 140 bucks right now that performs 100% better than my 2 and a half years old vcard?
The 7770 has a 80W TDP, hmmmm. lower the clocks to like 850-900 and with a custom PCB no extra power as well? Oh this sounds amazing!
